    SUMMARY JUDGMENT; GRANTING IN PART AND DENYING IN PART DEFENDANTS’ MOTION
    FOR PARTIAL SUMMARY JUDGMENT; DENYING PLAINTIFFS’ CROSS-MOTION FOR PARTIAL
    SUMMARY JUDGMENT
    I. INTRODUCTION
    This suit arising under the Freedom of Information Act (“FOIA”), 5 U.S.C. § 552, began
    in 2007, when Plaintiffs M. Gregg Bloche and Jonathan H. Marks sought records from multiple
    federal government entities concerning the involvement of medical professionals in designing
    and implementing interrogation tactics. Presently before the Court are two sets of motions.
    First, three Defendant agencies, (1) the Department of the Navy (“Navy”); (2) the Office of the
    Assistant Secretary of Defense for Health Affairs (“OASD-HA Policy”); and (3) the Department
    of Defense’s Office of the Deputy General Counsel for Personnel and Health Policy (“OASD-
    HAGC”), renew their motion for summary judgment. 1 See ECF No. 110. For the reasons set
    forth below, the Court grants in part and denies in part this motion.
    1
    These Defendants filed a renewed motion for summary judgment along with
    supplementary documentation to address deficiencies identified in the Court’s prior
    memorandum opinion concerning this set of records. See Bloche v. Dep’t of Def. (“Bloche II”),
    Second, separately before the Court are cross-motions for summary judgment concerning
    six other Defendant agencies: (1) the United States Army (“Army”); (2) the Office of the
    Director of National Intelligence (“ODNI”); 2 (3) the United States Special Operation Command
    (“SOCOM”); (4) the Defense Intelligence Agency (“DIA”); (5) the United States Central
    Command (“CENTCOM”); and (6) the Joint Task Force Guantanamo (“JTF-GTMO”). 3 See
    ECF Nos. 96, 97. 4 Each of these Defendant agencies conducted its own search in response to
    Plaintiffs’ FOIA requests, and the adequacy of Defendants’ searches are not at issue. 5 What is at
    
    370 F. Supp. 3d 40
    (2019). As noted therein, OASD-HA Policy and OASD-HAGC are
    components of a named Defendant, the Department of Defense (“DOD”), and are not formally
    Defendants in this suit. 
    Id. at 48
    n. 1. For consistency and clarity, the Court identifies the parties
    in the same manner and will occasionally refer to these DOD components as Defendants in this
    opinion. The Court refers to the March 2019 opinion as Bloche II to distinguish it from a 2017
    opinion in this same suit that concerned Defendant Navy. See Bloche v. Dep’t of Def. (“Bloche
    I”), 
    279 F. Supp. 3d 68
    (2017).
    2
    While the instant cross-motions were ripening, Defendant ODNI resolved Plaintiffs’
    challenges concerning both the documents that it had produced and the documents that it had
    referred to the State Department. See Pls.’ Mem. P. & A. Supporting Cross-Mot. for Partial
    Summ. J. (“Pls.’ Mem.”) 7, ECF No. 97-1 (discussing further releases by State Department); 
    id. at 8
    n.2 (noting that Plaintiffs no longer challenge two ODNI-associated documents); Pls.’ Reply
    Supporting Cross-Mot. (“Pls.’ Reply”) Ex. 1, Updated History of Disputed Docs. 7, ECF No.
    101-1 (documenting that Plaintiffs do not dispute the documents referred to State or any other
    documents produced by ODNI). Thus, the remainder of this opinion will not discuss Defendant
    ODNI or the State Department.
    3
    JTF-GTMO, CENTCOM, and SOCOM are components of DOD and are not, formally
    speaking, Defendants in this suit. The Court will nonetheless refer to these components as
    Defendants to address the records at issue with greater particularity.
    4
    ECF number 97 is substantively identical to ECF number 98, although 97 is labelled a
    cross-motion for partial summary judgment, whereas 98 is styled as Plaintiffs’ memorandum in
    opposition to Defendants’ motion for partial summary judgment and lacks one of the
    attachments. The Court refers exclusively to ECF number 97 in this opinion. Along similar
    lines, ECF number 99 is substantively identical to ECF number 100, although 99 is labelled as
    Defendants’ memorandum in opposition to Plaintiffs’ cross-motion and 100 is styled as a reply
    to Plaintiffs’ opposition and lacks two attachments. The Court refers exclusively to ECF number
    99 in this opinion.
    5
    Plaintiffs do not challenge the adequacy of the search at all, with one exception:
    Plaintiffs’ reply brief contends that Defendant Army has not performed an adequate search for
    four missing documents: Army 25, Army 26, Army 112, and Army 113. See Pls.’ Reply 2.
    2
    issue in these cross-motions is the application of FOIA exemptions to withhold in full or in part
    the documents produced by the agencies. For reasons that the Court will detail below after
    addressing Defendants’ renewed motion for summary judgment, see ECF No. 110, the
    Defendant agencies involved in the pending cross-motions for summary judgment, see ECF Nos.
    96, 97, have provided adequate justification for some, but not all of their claimed exemptions.
    The Court thus grants in part and denies in part Defendants’ motion for partial summary
    judgment and denies Plaintiffs’ cross-motion for partial summary judgment.
    II. LEGAL STANDARD
    Congress enacted FOIA to permit citizens to discover “what their government is up to.”
    U.S. Dep’t of Justice v. Reporters Comm. for Freedom of the Press, 
    489 U.S. 749
    , 773 (1989)
    (quoting EPA v. Mink, 
    410 U.S. 73
    , 105 (1973) (Douglas, J. dissenting)). FOIA requires the
    agency to disclose records located in response to a valid FOIA request, unless material in the
    records falls within one of FOIA’s nine statutory exemptions. 5 U.S.C. § 552(b); see also
    Judicial Watch, Inc. v. Dep’t of Def., 
    847 F.3d 735
    , 738 (D.C. Cir. 2017); NLRB v. Sears,
    Roebuck & Co., 
    421 U.S. 132
    , 136 (1975).
    Plaintiffs’ memorandum in support of their cross-motion for partial summary judgment included
    a single line in a footnote that purportedly “reserve[d] [the] right to object to Defendants’ alleged
    ‘thorough and exhaustive search’ for unredacted versions” of these documents. Pls.’ Mem. 25
    n.5. Plaintiffs’ reply brief then developed this objection for the first time. Courts in this Circuit
    have “generally held that issues not raised until the reply brief are waived.” Sitka Sound
    Seafoods, Inc. v. NLRB, 
    206 F.3d 1175
    , 1181 (D.C. Cir. 2000) (quoting Board of Regents of
    Univ. of Wash. v. EPA, 
    86 F.3d 1214
    , 1221 (1996)); see also Walker v. Pharm. Research & Mfrs.
    of Am., 
    461 F. Supp. 2d 52
    , 59 (D.D.C. 2006) (citing In re Asemani, 
    455 F.3d 296
    , 300 (D.C.
    Cir. 2006)). This principle holds when a party does not argue a point until its reply brief, even if
    the party referred to the argument in its opening brief. Sitka Sound Seafoods, 
    Inc., 206 F.3d at 1181
    . Here, by failing to contest the adequacy of Army’s search until its reply brief, Plaintiffs
    waived this argument. Thus, the Court addresses only the application of FOIA exemptions by
    each of the Defendant agencies.
    3
    “FOIA cases typically and appropriately are decided on motions for summary judgment.”
    Pinson v. U.S. Dep’t of Justice, 
    236 F. Supp. 3d 338
    , 352 (D.D.C. 2017) (quoting Defs. of
    Wildlife v. U.S. Border Patrol, 
    623 F. Supp. 2d 83
    , 87 (D.D.C. 2009)). In general, summary
    judgment is appropriate when “the movant shows that there is no genuine dispute as to any
    material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). A
    “material” fact is one capable of affecting the substantive outcome of the litigation. See
    Anderson v. Liberty Lobby, Inc., 
    477 U.S. 242
    , 248 (1986). A dispute is “genuine” if there is
    enough evidence for a reasonable factfinder to return a verdict for the non-movant. See Scott v.
    Harris, 
    550 U.S. 372
    , 380 (2007). In a FOIA suit, “summary judgment is appropriate if there are
    no material facts genuinely in dispute and the agency demonstrates ‘that its search for responsive
    records was adequate, that any exemptions claimed actually apply, and that any reasonably
    segregable non-exempt parts of records have been disclosed after redaction of exempt
    information.’” Prop. of the People, Inc. v. Office of Mgmt. and Budget, 
    330 F. Supp. 3d 373
    , 380
    (D.D.C. 2018) (quoting Competitive Enter. Inst. v. EPA, 
    232 F. Supp. 3d 172
    , 181 (D.D.C.
    2017)).
    A court addressing a motion for summary judgment in a FOIA suit is to review the matter
    de novo. See 5 U.S.C. § 552(a)(4)(B); Life Extension Found., Inc. v. Internal Revenue Serv., 
    915 F. Supp. 2d 174
    , 179 (D.D.C. 2013). The reviewing court may grant summary judgment based
    on the record and agency declarations if “the agency’s supporting declarations and exhibits
    describe the requested documents and ‘the justifications for nondisclosure with reasonably
    specific detail, demonstrate that the information withheld logically falls within the claimed
    exemption, and are not controverted by either contrary evidence in the record nor by evidence of
    agency bad faith.’” Pronin v. Fed. Bureau of Prisons, No. CV 17-1807, 
    2019 WL 1003598
    , at
    4
    *3 (D.D.C. Mar. 1, 2019) (quoting Larson v. Dep’t of State, 
    565 F.3d 857
    , 862 (D.C. Cir. 2009)
    (internal citation omitted)). “Ultimately, an agency’s justification for invoking a FOIA
    exemption is sufficient if it appears ‘logical’ or ‘plausible.’” Scudder v. Cent. Intelligence
    Agency, 
    254 F. Supp. 3d 135
    , 140 (D.D.C. 2017) (quoting Judicial 
    Watch, 715 F.3d at 941
    (internal citations omitted)). But exemptions are to be “narrowly construed.” Bloche II, 370 F.
    Supp. 3d at 50 (quoting Morley v. Cent. Intelligence Agency, 
    508 F.3d 1108
    , 1115 (D.C. Cir.
    2007)). An agency cannot justify its withholding by providing “[c]onclusory and generalized
    allegations of exemptions,” 
    Morley, 508 F.3d at 1114
    –15 (internal citations omitted), and an
    agency must do more than provide “summary statements that merely reiterate legal standards or
    present ‘far-ranging category definitions for information,’” Citizens for Responsibility & Ethics
    in Wash. v. U.S. Dep’t of Justice, 
    955 F. Supp. 2d 4
    , 13 (D.D.C 2013) (quoting King v. U.S.
    Dep’t of Justice, 
    830 F.2d 210
    , 221 (D.C. Cir. 1987)).
    III. DEFENDANTS’ RENEWED MOTION FOR SUMMARY JUDGMENT
    The sole issue in Defendants’ renewed motion for summary judgment, as noted
    previously, is Defendants’ application of FOIA exemptions. This Court’s March 2019
    memorandum opinion and order denied summary judgment with respect to nine documents,
    directing Defendants both to produce these documents for in camera review and to provide
    supplementary justification. The majority of these documents were withheld in full or in part
    pursuant to Exemption 5’s deliberative process privilege, 6 see 5 U.S.C. § 552(b)(2), and two
    6
    The seven documents originally withheld pursuant to Exemption 5 are OASD-HA
    Policy 28-35, 659, 758-59, 761-62, 765-66, and OASD-HAGC 272 and 563-68. See Bloche 
    II, 370 F. Supp. 3d at 54
    –55. After the Court’s March 2019 memorandum opinion, OASD-HAGC
    determined that OASD-HAGC 272 and 563-68 could be released with only the names of
    personnel redacted, pursuant to Exemption 6, and produced these documents to Plaintiffs. Defs.’
    Mem. P. & A. Supporting Renewed Mot. Partial Summ. J. (“Defs.’ Mem. P. & A. Supporting
    Renewed Mot.”) 4, ECF No. 110-1 (citing Ex. C, Second Declaration of Mark H. Herrington
    5
    were withheld pursuant to Exemption 7(E), which permits an agency to withhold information
    related to “techniques and procedures for law enforcement investigations and prosecutions,” 
    id. § 552(b)(7).
    7 The Court will address each of these exemptions (deliberative process privilege for
    Defendant OASD-HA and 7(E) for Defendant Navy) in turn. Because it finds that Defendant
    OASD-HA has justified its invocation of FOIA Exemption 5 for all but one of its withheld
    documents and that Defendant Navy has justified its invocation of FOIA Exemption 7(E) for
    both of its partially withheld documents, the Court will grant in part and deny in part
    Defendants’ renewed motion for summary judgment.
    A. Defendant OASD-HA Policy
    1. Exemption 5 – The Deliberative Process Privilege
    Exemption 5 of FOIA protects “inter-agency or intra-agency memorandums or letters that
    would not be available by law to a party other than an agency in litigation with the agency.” 5
    U.S.C. § 552(b)(5). The Supreme Court and the D.C. Circuit have construed Exemption 5 to
    exempt documents “normally privileged in the civil discovery context.” 
    Sears, 421 U.S. at 149
    ;
    see also Martin v. Office of Special Counsel, 
    819 F.2d 1181
    , 1184 (D.C. Cir. 1987). Exemption
    5 thus “incorporates the traditional privileges that the Government could assert in civil litigation
    against a private litigant”—including, as relevant here, “the deliberative process privilege.”
    Brown v. Dep’t of State, 
    317 F. Supp. 3d 370
    , 375 (D.D.C. 2018) (quoting Loving v. Dep’t of
    (“Second Herrington Decl.”) ¶¶ 6–7, ECF No. 110-3). Thus, the sole documents for which
    Plaintiffs continue to challenge Defendants’ Exemption 5 withholdings are OASD-HA Policy
    28-35, 659, 758-59, 761-62, and 765-66.
    7
    The Court also directed the OASD Defendants to reconsider the application of
    Exemption 6 to redact the domain portion of agency email addresses. See Bloche II, 370 F.
    Supp. 3d at 58–59. The parties reached agreement on this issue and filed a motion to amend this
    order, see ECF No. 108, which this Court granted on April 29, 2019, see ECF No. 111.
    Exemption 6 is, accordingly, no longer at issue in this suit.
    6
    Def., 
    550 F.3d 32
    , 37 (D.C. Cir. 2008) (internal quotation mark and citation omitted)); see also
    Baker & Hostetler LLP v. U.S. Dep’t of Commerce, 
    473 F.3d 312
    , 321 (D.C. Cir. 2006).
    The deliberative process privilege protects “documents reflecting advisory opinions,
    recommendations and deliberations comprising part of a process by which governmental
    decisions and policies are formulated.” 
    Loving, 550 F.3d at 38
    (quoting U.S. Dep’t of the
    Interior v. Klamath Water Users Protective Ass’n, 
    532 U.S. 1
    , 8 (2001)). It aims to “prevent
    injury to the quality of agency decisions,” 
    Sears, 421 U.S. at 151
    , and “rests on the obvious
    realization that officials will not communicate candidly among themselves if each remark is a
    potential item of discovery and front page news,” Klamath Water Users Protective 
    Ass’n, 532 U.S. at 8
    –9. The privilege thus balances the merits of transparency against the concern that
    agencies will be “forced to operate in a fishbowl.” Petroleum Info. Corp. v. U.S. Dep’t of the
    Interior, 
    976 F.2d 1429
    , 1434 (D.C. Cir. 1992).
    For the deliberative process privilege to apply, the record must “bear on the formulation
    or exercise of agency policy-oriented judgment.” Petroleum Info. 
    Corp., 976 F.2d at 1435
    (emphasis in original). To qualify, the record at issue must be both predecisional and
    deliberative. See Prop. of the 
    People, 330 F. Supp. 3d at 382
    . To be predecisional, a record
    must be antecedent to the adoption of an agency policy. See Access Reports v. U.S. Dep’t of
    Justice, 
    926 F.2d 1192
    , 1194 (D.C. Cir. 1991). Although “the term ‘deliberative’ does not add a
    great deal of substance to the term ‘pre-decisional,’” it essentially means “that the
    communication is intended to facilitate or assist development of the agency’s final position on
    the relevant issue.” Nat’l Sec. Archive v. Cent. Intelligence Agency, 
    752 F.3d 460
    , 463 (D.C. Cir.
    2014).
    7
    Moreover, the agency bears the burden of showing that the privilege properly applies.
    See Dillon v. U.S. Dep’t of Justice, No. 17-1716, 
    2019 WL 249580
    , at *8 (D.D.C. Jan 17, 2019)
    (citing Prop. of the 
    People, 330 F. Supp. 3d at 380
    ). In order to meet its burden, the agency must
    offer a “relatively detailed justification” of its application of the privilege. Elec. Privacy Info.
    Ctr. v. U.S. Drug Enf’t Agency, 
    192 F. Supp. 3d 92
    , 103 (D.D.C. 2016) (quoting Mead Data
    Cent., Inc. v. U.S. Dep’t of Air Force, 
    566 F.2d 242
    , 251 (D.C. Cir. 1977)). “An agency may
    rely on detailed affidavits, declarations, a Vaughn index, in camera review, or a combination of
    these tools.” Elec. Frontier Found. v. U.S. Dep’t of Justice, 
    57 F. Supp. 3d 54
    , 59 (D.D.C. 2014)
    (quoting Comptel v. Fed. Commc’n Comm’n, 
    910 F. Supp. 2d 100
    , 111 (D.D.C. 2012)).
    “Ultimately, an agency’s justification for invoking a FOIA exemption is sufficient if it appears
    logical or plausible.” Dillon, 
    2019 WL 249580
    , at *8 (quoting Wolf v. Cent. Intelligence Agency,
    
    473 F.3d 370
    , 374–75 (D.C. Cir. 2007) (internal quotation marks and citation omitted)).
    2. Defendant’s Claims of Deliberative Process Privilege
    At issue here are five documents, OASD-HA Policy 28-35, 659, 758-59, 761-62, and
    765-66, for which Defendant OASD-HA Policy did not previously provide “sufficiently detailed
    justifications” for its application of FOIA exemptions. Bloche 
    II, 370 F. Supp. 3d at 53
    . As this
    Court previously explained, the contested documents fall into two categories: first, agency policy
    documents and associated discussions and, second, possible communications with outside
    entities. 
    Id. at 51.
    “[B]oth of these categories of documents fall within the scope of the
    deliberative process privilege—as long as each particular privilege claim is properly supported
    by the ‘relatively detailed justification’ that FOIA requires.” 
    Id. (quoting Mead
    Data Cent., 
    Inc., 566 F.2d at 251
    ). For the following reasons, OASD-HA Policy has now adequately justified its
    8
    privilege claim for almost all of the challenged OASD-HA Policy documents, but it has not
    established that the privilege properly applies to OASD HA Policy 28-35.
    a. OASD HA Policy 28-35
    OASD HA Policy 28-35 is an email chain from 2008 along with an attached information
    memo (“info memo”) discussing proposed amendments to DOD detainee healthcare policies.
    Second Herrington Decl. ¶ 8; see also Defs.’ Mem. P. & A. Supporting Renewed Mot. 12–13.
    The info memo discusses proposed amendments to DoDI 2310.08E and 2310.01E that were
    offered by a representative from the group Physicians for Human Rights (“PHR”). Second
    Herrington Decl. ¶ 8. PHR’s specific proposed text is appended to the info memo produced by
    the agency. 
    Id. PHR submitted
    this material in response to the Assistant Secretary of Defense
    for Health Affair’s (“ASD(HA)’s”) desire for input regarding a potential amendment to these
    policies. 
    Id. Exemption 5
    was not applied to the email chain, but the attached info memo and
    proposed amendments offered by PHR are withheld in full under Exemption 5’s deliberative
    process privilege. 
    Id. Defendants justify
    this withholding as authorized by the “consultant
    corollary” exception to Exemption 5’s general rule that a record must be an “interagency or
    intra-agency communication,” 5 U.S.C. § 552(b)(5), to qualify as privileged. Defs.’ Mem. P. &
    A. Supporting Renewed Mot. 13–14. Under the consultant corollary, “records of
    communications between an agency and outside consultants qualify as ‘intra-agency’ for
    purposes of Exemption 5 if they have been ‘created for the purpose of aiding the agency’s
    deliberative process.’” 100Reporters LLC v. U.S. Dep’t of Justice, 
    248 F. Supp. 3d 115
    , 146
    (D.D.C. 2017) (quoting Pub. Citizen v. U.S. Dep’t of Justice, 
    111 F.3d 168
    , 170 (D.C. Cir. 1997)
    (emphasis in original)); see also Pub. Emps. for Envtl. Responsibility v. U.S. Section, Int’l
    Boundary & Water Comm’n, U.S.-Mex., 
    740 F.3d 195
    , 201 (D.C. Cir. 2014) (“This Court has
    9
    also interpreted the phrase ‘intra-agency’ in Exemption 5 to go beyond the text and include U.S.
    agency records authored by non-agency entities if those records were solicited by a U.S. agency
    in the course of its deliberative process.” (citing McKinley v. Bd. of Governors of the Fed.
    Reserve Sys., 
    647 F.3d 331
    , 336 (D.C. Cir. 2011)). Defendants offer that this is just such a
    communication: “PHR’s proposed amendments and the subsequent ‘info memo’ summarizing
    PHR’s proposals were created to aid the ASD(HA)’s deliberations regarding possible
    amendment of the detainee healthcare policies and not to solicit a benefit at the expense of a
    competitor.” Defs.’ Mem. P. & A. Supporting Renewed Mot. 14.
    In challenging this withholding, Plaintiffs primarily contest the vagueness of OASD-HA
    Policy’s description of the document and the attachments. See, e.g., Pls.’ Mem. P. & A. Opp’n
    Defs.’ Renewed Mot. Partial Summ. J. (“Pls.’ Mem. P. & A. Opp’n”) 15 (“Even if one assumes
    (as Defendants imply but do not make clear) that the attached memo to the email chain contains
    not just PHR recommendations but comments by DoD personnel on the amendments,
    Defendants still have not explained how disclosure would inhibit full and frank exchange of
    views.”). Plaintiffs also suggest that this communication was not predecisional because the
    policies were issued in 2006, yet the dialogue regarding proposed amendments occurred in 2008,
    such that the document was not “generated before the adoption of an agency policy” in the way
    that the deliberative process privilege requires. Pls.’ Mem. P. & A. Opp’n 14 (quoting Coastal
    States Gas Corp. v. U.S. Dep’t of Energy, 
    617 F.2d 854
    , 861 (D.C. Cir. 1980)).
    Neither party’s argument is entirely persuasive. In contesting the predecisional status of
    the document, Plaintiffs misconstrue the relevant policymaking timeline. Here, as Defendants
    note, the policy deliberations concerned whether to amend the policy in 2008. An agency may
    deliberate about potential changes to a policy before concluding that there should be no
    10
    amendment, and the privilege may still apply so long as the agency establishes the role that the
    documents at issue played in the deliberative process. Accord Nat’l Sec. Archive v. Cent.
    Intelligence Agency, 
    752 F.3d 460
    , 463 (D.C. Cir. 2014) (“There may be no final agency
    document because a draft died on the vine. But the draft is still a draft and thus still pre-
    decisional and deliberative.”). Because OASD-HA Policy’s supplemental declaration specifies
    how opinions were generated in deliberation about a specific policy proposal that predated a final
    policy determination, it establishes that the document was part of a policy-oriented
    decisionmaking process in the manner required to invoke Exemption 5.
    That said, without more clarity about PHR’s relationship to the agency in generating the
    material, this Court cannot determine the propriety of applying the deliberative process
    privilege—which, again, only applies to “inter-agency or intra-agency” documents. 5 U.S.C. §
    552(b)(5). The problem is that OASD-HA Policy has not provided enough explanation about its
    relationship with PHR, a non-agency actor, for the Court to assess whether OASD-HA Policy
    may properly rely on the “consultant corollary” exception to Exemption 5. It is true, as
    Defendants point out, that the involvement of an entity outside of the agency in generating a
    document does not necessarily bar the application of the privilege. See Defs.’ Mem. P. & A.
    Supporting Renewed Mot. 14. But there are limitations on when an agency can rely on this
    exception. Critically, an agency can invoke the consultant corollary only if the “outside
    consultant did not have its own interests in mind.” Pub. Emps. for Envtl. 
    Responsibility, 740 F.3d at 201
    –02. Here, the agency received PHR’s proposal after the ASD(HA) “asked his staff
    to meet with th[e] [PHR] representative to get their views for his consideration.” Second
    Herrington Decl. ¶ 8. Without more detail that OASD-HA Policy fails to provide, this statement
    does not discharge OASD-HA Policy’s burden to establish that the PHR “consultant function[ed]
    11
    just as an [agency] employee would be expected to do”—and not as an advocate representing “an
    interest of its own, or the interests or any other client, when it advise[d] the agency.” 
    McKinley, 647 F.3d at 336
    (quoting Klamath Water Users Protective 
    Ass’n, 532 U.S. at 12
    ). In fact,
    Plaintiffs characterize PHR’s recommendations not as a neutral proposal, but rather as a
    “proposal from a human rights group,” Pls.’ Mem. P. & A. Opp’n 15, that would ostensibly
    represent its own interests in providing such a proposal. In some respects, the relationship
    sounds more like an interested advocacy group commenting on a proposed agency policy (as
    happens routinely during proposed rulemaking) than it does an agency consultant providing
    internal advice. Thus, until the agency clarifies the context in which PHR was asked to provide
    this information and the relationship between the organization and the agency in the delivery of
    advice, Defendants’ justification is insufficient to demonstrate “that any exemptions claimed
    actually apply.” Prop. of the People, 
    Inc., 330 F. Supp. 3d at 380
    (quoting Competitive Enter.
    
    Inst., 232 F. Supp. 3d at 181
    ).
    b. OASD-HA Policy 659
    OASD 659 is an undated single page of handwritten notes by an unknown author that
    was located alongside a draft investigation report with the title, “Medical Issues Relevant to
    Interrogation and Detention Operations.” Second Herrington Decl. ¶ 9. The agency withheld the
    draft investigation report, OASD-HA Policy 660-690, in full under Exemption 5, and this Court
    previously found the draft to be privileged. Id.; see Bloche 
    II, 370 F. Supp. 3d at 53
    –54 (finding
    it “clear that the draft was part of a policy-oriented decisionmaking process,” such that it was
    privileged). Defendants equate the handwritten notes to marginal comments in a draft document
    that were “presumably either helping to edit the draft or writing down excerpts from the report to
    participate in further deliberations.” Second Herrington Decl. ¶ 9. Plaintiffs contest this
    12
    designation, arguing that that the agency’s withholding of the document is unjustified because
    OASD-HA cannot specify whether the notes were editorial comments or excerpts from the
    report, such that the agency has not indicated the document’s role in the deliberative process.
    Pls.’ Mem. P. & A. Opp’n 16. This argument about the function of the notes, however, is
    wrong-headed. Regardless of whether the notes were created to edit the draft or to participate in
    further deliberations about the draft, the agency’s declaration attesting that the notes reference
    particular pages of the draft, see Second Herrington Decl. ¶ 8, and the Court’s in camera review
    of the notes establish that they are the opinions of the writer regarding particular pages of the
    draft. As such, OASD-HA Policy has amply specified the notes’ relationship to the draft and, by
    extension, how they contributed to a drafting “process by which governmental decisions and
    policies are formulated.” 
    Loving, 550 F.3d at 38
    (quoting Klamath Water Users Protective
    
    Ass’n, 532 U.S. at 8
    ). Given that the draft is properly withheld in full pursuant to Exemption 5, it
    is logical that the notes are also properly withheld pursuant to that same privilege claim. Thus,
    the agency has adequately justified its application of the privilege here.
    c. OASD-HA Policy 758-59, 761-62, and 765-66
    Plaintiffs’ final deliberative process challenge concerns OASD-HA Policy 758-59, 761-
    62, and 765-66, which involve the same policy proposal and associated agency communications.
    Defendants’ supplemental declaration provides specificity about the documents that was lacking
    in its prior submissions. See Bloche 
    II, 370 F. Supp. 3d at 54
    . OASD-HA Policy 765-66 is a
    “request from the Army” seeking approval from the ASD(HA) “regarding the Army’s proposed
    plan for handling a personnel matter under the provisions of DoDI 2310.08E,” including “the
    Army’s rationale for approving the request.” Second Herrington Decl. ¶ 11. OASD-HA Policy
    758-59 and 761-62 are email communications concerning the Army’s Request. 
    Id. ¶ 10.
    OASD-
    13
    HA Policy 761-62 consists of the ASD(HA) military assistant’s email seeking “a
    recommendation from Health Affairs staff members on whether to grant” the Army’s request,
    and OASD-HA Policy 758-59 is the reply email that contains the recommendation provided by
    these staff members. 
    Id. Plaintiffs contend
    that this additional detail is not enough, contesting
    the use of the term “personnel-related matter” as “an extraordinarily vague and broad term that
    provides no specificity about the nature of the matter or how it related to decision-making
    policy.” Pls.’ Mem. P. & A. Opp’n 16–17.
    Although the Court agrees that “personnel-related matter” is an imprecise designation in
    the abstract, when the phrase is read in context, the agency has provided additional specificity
    and related the matter to a particular deliberative process. The declaration provided gives
    enough detail for the Court to draw the conclusion that the “personnel-related matter arose under
    the provisions of DoD’s detainee healthcare policy – DoDI 2310.08E – and stems from a request
    from the Army seeking the ASD(HA)’s approval of the Army’s proposed plan for handling the
    matter.” Defs.’ Reply Supporting Renewed Mot. Partial Summ. J. 8 (citing Second Herrington
    Decl. ¶¶ 10–11). Because these communications were antecedent to any policy decision by
    ASD(HA) and written by individuals without decision-making authority, and because they
    operated to “facilitate or assist development of the agency’s final position on the relevant issue,”
    Nat’l Sec. 
    Archive, 752 F.3d at 463
    , OASD-HA Policy has shown that the emails in OASD-HA
    Policy 758-59 and 761-62 qualify for the privilege. Moreover, the agency’s supplemental
    discussion establishes that OASD-HA Policy 765-66, the text of the Army’s initial request, also
    qualifies. This text contains “the Army’s rationale” and “proposed plan” and is thus precisely
    the sort of document “seek[ing] a decision” that Exemption 5 protects in order to encourage
    uninhibited inter-agency dialogue. Second Herrington Decl. ¶ 11.
    14
    d. Segregability
    Before approving the agency’s invocation of the privilege with respect to OASD-HA
    Policy OASD-HA Policy 659, 758-59, 761-62, and 765-66, however, this Court must also “make
    specific findings of segregability regarding the documents to be withheld.” 8 Sussman v. U.S.
    Marshals Serv., 
    494 F.3d 1106
    , 1117 (D.C. Cir. 2007) (citations omitted); see also 5 U.S.C. §
    552(b). This analysis is especially critical for the deliberative process privilege, which “does not
    protect documents in their entirety; if the government can segregate and disclose non-privileged
    factual information within a document, it must.” 
    Loving, 550 F.3d at 38
    (citation omitted). The
    agency may meet its segregability burden with a combination of a Vaughn Index and an affidavit
    or declaration establishing with “reasonably specificity” that it released all segregable material.
    See Bloche 
    II, 370 F. Supp. 3d at 55
    (citing Johnson v. Exec. Office of U.S. Attorneys, 
    310 F.3d 771
    , 776 (D.C. Cir. 2002)).
    Here, as described above, OASD-HA Policy has provided supplementary material in the
    form of a declaration that details the agency’s withholdings. The agency has further averred that
    it conducted a “line-by-line review of OASD-HA Policy’s records” and determined that it
    “released all reasonably segregable information.” Second Herrington Decl. at ¶ 12. Plaintiffs
    contend that this statement is not enough, arguing that the withholding of draft documents in full
    suggests that OASD-HA Policy did not release non-exempt, factual information. Pls.’ Mem. P.
    & A. Opp’n at 17–18. But this bare allegation does not overcome the “presumption” that the
    agency “complied with the obligation to disclose reasonably segregable material.” 
    Sussman, 494 F.3d at 1117
    (citing Boyd v. U.S. Marshalls Serv., 
    475 F.3d 381
    , 391 (D.C. Cir. 2007)). Nor do
    8
    The Court will assess whether OASD-HA Policy has properly segregated material in
    OASD-HA Policy 28-35 after further justification is provided for the withholding of this
    document.
    15
    Plaintiffs provide any evidence of an “alleged Government impropriety” that might overcome
    this presumption. Nat’l Archives & Records Admin. v. Favish, 
    541 U.S. 157
    , 174 (2004). Thus,
    the supplemental materials submitted discharge the agency’s obligation, and the agency may
    withhold OASD-HA Policy 695, 758-59, 761-62, and 765-66 pursuant to Exemption 5’s
    deliberative process privilege. 9
    B. Defendant Navy
    The sole remaining issue in Defendants’ renewed motion for summary judgment is
    Defendant Navy’s application of Exemption 7(E) to withhold information in two documents,
    Navy 35 and Navy 38. See Defs.’ Mem. P. & A. Supporting Renewed Mot. 5–7. Both of these
    documents “pertain to detainee interrogation operations at the United States Naval Base,
    Guantanamo Bay, Cuba.” 
    Id. at 7
    (citing 
    id. Ex. B,
    Declaration of Lieutenant Peter Tyson Marx,
    JAGC, USN (“Marx Decl.”) ¶ 7a-b, ECF No. 110-3). For the reasons forth below, Navy has
    justified its invocation of Exemption 7(E) for the withheld portions of Navy 35 and Navy 38.
    1. Exemption 7(E)
    FOIA Exemption 7(E) permits an agency to withhold “records or information compiled
    for law enforcement purposes, but only to the extent that the production of such law enforcement
    9
    In contesting the application of this privilege and at various other points, Plaintiffs raise
    segregability issues and contend that Defendants must release “information sought and
    subsequently received” that “was in fact incorporated into the final decision or policy.” Pls.’
    Mem. P. & A. Opp’n 17. But as the Court explained in its March 2019 memorandum opinion,
    this stance misstates the law: “FOIA does not require an agency to release portions of any draft
    that are ultimately repeated in the final policy.” Bloche 
    II, 370 F. Supp. 3d at 53
    n.3. The
    deliberative process privilege is not rooted in formal determinations of this sort. Rather, it
    functions to shield material when its disclosure would harm agency deliberations by “divulg[ing]
    information regarding ‘decisions to insert or delete material or to change [the] draft’s focus or
    emphasis’ and thus ‘would stifle the creative thinking and candid exchange of ideas necessary to
    produce good . . . work.” 
    Id. (quoting Hardy
    v. Bureau of Alcohol, Tobacco, Firearms, and
    Explosives, 
    243 F. Supp. 3d 155
    , 174 (D.D.C. 2017) (alteration and omission in original)
    (internal citation omitted)); see also Dudman Commc’ns Corp. v. Dep’t of Air Force, 
    815 F.2d 1565
    , 1569 (D.C. Cir. 1987).
    16
    records or information . . . would disclose techniques and procedures for law enforcement
    investigations or prosecutions if such disclosure could reasonably be expected to risk
    circumvention of the law.” 5 U.S.C. § 552(b)(7)(E). An agency seeking to apply Exemption
    7(E) must, accordingly, make two showings. First, to demonstrate that the “records or
    information” were “compiled for law enforcement purposes,” 
    id., the agency
    must establish both
    “a rational nexus between the investigation and one of the agency’s law enforcement duties” and
    a “connection between an individual or incident and a possible security risk or violation of
    federal law,” Blackwell v. Fed. Bureau of Investigation, 
    646 F.3d 37
    , 40 (D.C. Cir. 2011)
    (quoting Campbell v. U.S. Dep’t of Justice, 
    164 F.3d 20
    , 32 (D.C. Cir. 1998)). Second,
    Exemption 7(E) requires the agency to “demonstrate logically how the release of the requested
    information might create a risk of circumvention of the law.” Mayer Brown LLP v. Internal
    Revenue Serv., 
    562 F.3d 1190
    , 1194 (D.C. Cir. 2009) (quoting PHE, Inc. v. U.S. Dep’t of Justice,
    
    943 F.2d 248
    , 251 (D.C. Cir. 1993). These requirements must be met in a nonconclusory
    fashion, yet there is a “relatively low bar for the agency to justify withholding.” 
    Blackwell, 646 F.3d at 42
    .
    2. Defendant’s Application of Exemption 7(E)
    a. Navy 35 and Navy 38
    Navy 35 is a six-page memorandum dated January 31, 2001, from the Naval Criminal
    Investigative Service (“NCIS”) Director to the Navy General Counsel that was “attached to a
    one-page memorandum from the Navy General Counsel to the Assistant Secretary of Defense
    (Special Operations & Low Intensity Conflict) dated February 4, 2003, with the subject line
    ‘Proposed Alternative Approach to Interrogations.’” Marx Decl. ¶ 7a. This one-page
    17
    memorandum has been released in full to Plaintiffs, 
    id., and only
    the redactions in the six-page
    memorandum itself are presently contested.
    Navy 38 is an eighteen-page document that partially overlaps with the material contained
    in Navy 35. See Marx Decl. ¶ 7b. Specifically, Navy 38 consists of the same one-page
    “Proposed Alternative Approach to Interrogations” memorandum and the same six-page
    memorandum contained in Navy 35. 
    Id. Navy 38
    additionally includes an eleven-page appendix
    entitled “Special Recommendations for Interrogators of Al-Qa’ida Detainees at Guantanamo
    Bay, Cuba.” 
    Id. This appendix
    is partially withheld under Exemption 7(E). 
    Id. ¶ 7b(2).
    Navy offers that the information contained in both Navy 35 and Navy 38 “readily meets
    the threshold requirement of Exemption 7”—that the materials were “compiled for law
    enforcement purposes,” 5 U.S.C. § 553(b)(7)(E)—because it was “compiled to assist” NCIS
    “agents and other law enforcement personnel carry out their investigatory mission.” Marx Decl.
    ¶ 7b(1). Navy further states that disclosure of the redacted portions of the six-page memorandum
    appearing in both Navy 35 and Navy 38 would reveal “psychological and strategic approaches to
    interviewing detainees that are not generally known to the public.” 
    Id. ¶ 7b(2).
    The agency
    paints a dim picture of public disclosure, warning that the information, if revealed, “could
    reasonably be expected to risk circumvention of the law because current and future military
    detainees could use the information to evade interrogation,” thereby “significantly lower[ing] the
    effectiveness of these interviewing techniques” in ways that “could lead to unreliable
    information being obtained from interview subjects” in the future. 
    Id. The agency
    offers
    additional discussion of the withheld information in Navy 38, which consists of “detailed
    psychological strategies and techniques designed to build rapport with Al Qa’ida detainees . . .
    that are not generally known to the public,” and the release of which the agency warns could
    18
    compromise future interrogations “because current and future military detainees could use the
    information to evade interrogation.” 
    Id. ¶ 7b(3).
    For this document, Navy also offers further
    specification, noting that the document contains “details” concerning personnel, timing, the
    “reliability of certain kinds of information,” and “psychological and physical indicators” for the
    interviewer to note. 
    Id. Plaintiffs make
    three arguments concerning the agency’s application of 7(E). First,
    Plaintiffs question “what law enforcement purpose is involved.” Pls.’ Mem. P. & A. Opp’n 10.
    Second, Plaintiffs contend that Navy has not established “exactly what laws would purportedly
    be circumvented” if the psychological techniques and strategies discussed in the withheld
    portions of the documents were released. 
    Id. Finally, Plaintiffs
    contend that Navy’s asserted
    harms are baseless because “some (if not all) of the[] techniques have either been changed or
    rendered unlawful” in the “intervening years,” such that public disclosure of the techniques
    cannot lead to a present-day risk of circumvention. 
    Id. Based on
    the supplementary declaration and in camera review of the agency’s
    withholdings, Navy has the better argument on all three fronts. For one, the agency has cleared
    Exemption 7(E)’s threshold requirement. NCIS, which is located within the Department of the
    Navy, is “the civilian federal law enforcement agency uniquely responsible for investigating
    felony crime, preventing terrorism, and protecting secrets” for the U.S. Navy and U.S. Marine
    Corps. Marx Decl. ¶ 7b(1). NCIS is tasked with a “counterterrorism mission” and “is
    responsible for detecting, deterring, and disrupting terrorism worldwide through a wide array of
    investigative and operational capabilities.” 
    Id. As part
    of this mission, the agency has operated
    alongside “other law enforcement agencies” to “engage[] in investigatory activities related to the
    September 11, 2001, terrorist attacks, and the individuals detained at the United States Naval
    19
    Base at Guantanamo Bay, Cuba.” 
    Id. As Defendants
    argue, the NCIS mission centers on
    matters of counterterrorism and national security, which courts in this Circuit have found to fall
    within “the realm of law enforcement purposes sufficient to justify withholding based on
    Exemption 7.” See Defs.’ Mem. P. & A. Supporting Renewed Mot. (citing Am. Civil Liberties
    Union of S. Cal. v. U.S. Citizenship & Immigration Servs., 
    133 F. Supp. 3d 234
    , 242 (D.D.C.
    2015) (citations omitted)); see also Strang v. U.S. Arms Control & Disarmament Agency, 
    864 F.2d 859
    , 862 (D.C. Cir. 1989) (reading the term “law enforcement” as “encompassing the
    enforcement of national security laws as well”); Pratt v. Webster, 
    673 F.2d 408
    , 420 (D.C. Cir.
    1982) (concluding that there must be a connection between the “activities that give rise to the
    documents sought” and “enforcement of federal laws or . . . the maintenance of national
    security”).
    This description establishes an adequate connection between the records at issue and
    NCIS’s law enforcement duties. See 
    Blackwell, 646 F.3d at 40
    (quoting 
    Campbell, 164 F.3d at 32
    ). Logically, NCIS cannot carry out its law enforcement function with respect to the
    investigation of individuals detained at the Naval Base in Guantanamo Bay, Cuba, Marx Decl. ¶
    7b(1), without an established approach to interrogation. Based on the titles of the materials and
    the agency’s discussion of them, the documents were drafted to reevaluate the agency’s approach
    to interrogation. Thus, so long as NCIS compiled materials for law enforcement purposes and
    satisfies the second prong of Exemption 7(E)—discussed next—it may invoke the exemption.
    Although 7(E) sets a low bar, clearing it nonetheless requires more than merely restating
    the relevant legal standard. Navy’s declaration clears the bar for Navy 38: the Marx Declaration
    provides particularized details concerning aspects of the withheld eleven-page memorandum,
    such as details regarding “timing of demands” and “physical and psychological indicators,”
    20
    disclosure of which it asserts could “reasonably be expected to risk circumvention of the law
    because current and future military detainees could use the information to evade interrogation.”
    
    Id. at ¶
    7b(3). Contrary to Plaintiffs’ argument, the law does not demand that Defendants
    identify a particular law that would be evaded; rather, FOIA asks only that the agency
    “demonstrate logically how the release of the requested information might create a risk of
    circumvention of the law.” 
    Blackwell, 646 F.3d at 42
    (quoting Mayer Brown 
    LLP, 562 F.3d at 1194
    (alterations omitted)). The justification provided for Navy 38 establishes a logical chain
    that connects the information in the documents, in sufficient detail, to make this demonstration
    with regard to the eleven-page appendix. But the agency’s justification falls below even the low
    bar of 7(E) for the six-page memorandum that appears in both Navy 35 and Navy 38. All that
    Navy offers is a permutation of the legal standard, made without particularity: the threat that the
    public release of the document would compromise the effectiveness of the interrogation
    techniques at issue. See Marx Decl. ¶¶ 7b(2)-(3). What Navy has failed to provide in its
    supplemental filings are adequate details (of the sort it offered for Navy 38) about what kinds of
    information the document contains. As such, it has not specified in a nonconclusory way how
    release of the information “could reasonably be expected to risk circumvention of the law.” 5
    U.S.C. § 552(b)(7)(E).
    That said, an assertion made by a law enforcement agency invoking Exemption 7(E) is
    entitled to deference, see 
    Campbell, 164 F.3d at 32
    , and the Court’s in camera review of the
    document indicates that the partial redaction is appropriate in order for Navy to shield particular
    details of its interrogation strategy. Plaintiffs’ third argument concerning timing does not change
    this conclusion. As Defendants note, the Marx Declaration refers to a risk of evasion for
    “current and future military detainees” and the potential impact on “future investigations and
    21
    interviews.” Defs.’ Reply Supporting Renewed Mot. 4 (citing Marx Decl. ¶¶ 7b(2)-(3)).
    Plaintiffs have not pointed to any reason to discredit this statement. Taking this sworn
    declaration at its word, it appears that the techniques are in fact still in use, and Plaintiffs’
    contention is unavailing. Thus, Navy may withhold in part Navy 35 and Navy 38 pursuant to
    FOIA Exemption 7(E). 10
    IV. CROSS-MOTIONS FOR SUMMARY JUDGMENT
    As previously stated, also before the Court are cross-motions for summary judgment
    involving a different set of Defendant agencies—Army, SOCOM, DIA, CENTCOM, and JTF-
    GTMO—and Plaintiffs’ challenge to these agencies’ application of FOIA exemptions. See ECF
    Nos. 96, 97. Sixty nine of the seventy-eight documents contested at this juncture involve
    Defendant Army. See Pls.’ Reply Ex. 1, Updated History of Disputed Docs, ECF No. 101-1. 11
    Army invokes various combinations of deliberative process, attorney-client, and attorney work
    product privilege pursuant to FOIA Exemption 5, see 5 U.S.C. § 552(b)(5), to withhold sixty-
    nine documents in part or in full, 12 see Pls.’ Reply Ex. 1, Updated History of Disputed Docs. 2–

    This Court previously confirmed that Defendant Navy satisfied its burden confirming
    segregability, see Bloche 
    II, 370 F. Supp. 3d at 55
    –56, and no new arguments have been raised
    nor any new evidence presented on this matter. The Court thus need not reassess this issue here.

    Because this table is not paginated, the Court refers to the ECF page numbers when
    discussing it.

    Defendant Army originally also applied FOIA Exemption 1, see 5 U.S.C. § 552(b)(1),
    to Army 112 and Army 113. However, because the Army cannot locate unredacted versions of
    these documents, it is not possible for an Original Classification Authority to conduct a
    classification review in the manner that Exemption 1 requires. Defs.’ Mot. Partial Summ. J. Ex.
    B, Declaration of Major John E. Swords (“Swords Decl.”) ¶ 5 n.2, ECF No. 96-3. The Army
    “relies on its prior Exemption 5 determination,” conducted in 2008, “for purposes of this
    motion.”

    application of Exemption 5 to withhold in full Army 112 and Army 113.

    applied by the other four Defendant agencies. For the reasons set forth below, only Defendant
    CENTCOM has provided sufficient justification for all of the claimed exemptions.
    A. Army
    1. Exemption 5
    Again, Exemption 5 exempts documents that are “normally privileged in the civil
    discovery context.” 
    Sears, 421 U.S. at 149
    . In addition to the deliberative process privilege,
    which this Court discussed above in addressing Defendants’ renewed motion for partial summary
    judgment, ECF No. 110, Exemption 5 includes two other privileges that Army also invokes: the
    attorney-client privilege, and the work product privilege. See 
    Brown, 317 F. Supp. 3d at 375
    ;
    
    Loving, 550 F.3d at 37
    .
    The attorney-client privilege covers “confidential communications between an attorney
    and his client relating to a legal matter for which the client has sought professional advice.”
    Mead Data Cent., 
    Inc., 566 F.2d at 252
    . It is not limited to the context of litigation, see 
    id. at 252–53;
    rather, it “also protects communications from attorneys to their clients if the
    communications ‘rest on confidential information obtained from the client.’” Tax Analysts v.
    Internal Revenue Serv., 
    117 F.3d 607
    , 618 (D.C. Cir. 1997) (quoting In re Sealed Case, 
    737 F.2d 94
    , 99 (D.C. Cir. 1984)). If the communications suggest that “the Government is dealing with its
    attorneys as would any private party seeking advice to protect personal interests,” Coastal 
    States, 617 F.2d at 863
    , then a court may infer confidentiality. That said, a court should narrowly
    construe the attorney-client privilege, which “protects only those disclosures necessary to obtain
    informed legal advice which might not have been made absent the privilege.” 
    Id. at 862–63
    (quoting Fisher v. United States, 
    425 U.S. 391
    , 403 (1976)).
    23
    The work product doctrine “shields materials ‘prepared in anticipation of litigation or for
    trial by or for [a] party or by or for that . . . party’s representative (including the . . . party’s
    attorney, consultant, . . . or agent).’” Tax 
    Analysts, 117 F.3d at 620
    (quoting Fed. R. Civ.
    P. 26(b)(3)); see also Hickman v. Taylor, 
    329 U.S. 495
    (1947). This doctrine protects
    deliberative materials as well as “factual materials prepared in anticipation of litigation.” Tax
    
    Analysts, 117 F.3d at 620
    (citing Martin v. Office of Special Counsel, 
    819 F.2d 1181
    , 1184–87
    (D.C. Cir. 1987); A. Michael’s Piano, Inc. v. Fed. Trade Comm’n, 
    18 F.3d 138
    , 147 (2d Cir.
    1994)). Thus, it provides relatively broader coverage than the deliberative process privilege.
    However, to qualify for such coverage, the document must have been prepared “in anticipation
    of foreseeable litigation.” Schiller v. NLRB, 
    964 F.2d 1205
    , 1208 (D.C. Cir. 1992), abrogated on
    other grounds by Milner v. Dep’t of Navy, 
    562 U.S. 562
    (2011) (emphasis added) (citing
    Delaney, Migdail & Young, Chartered v. Internal Revenue Serv., 
    826 F.2d 124
    , 127 (D.C. Cir.
    1987)). To establish that litigation is foreseeable, the bare fact that “litigation might someday
    occur” is insufficient. Senate of the Commonwealth of Puerto Rico on Behalf of Judiciary
    Comm. v. U.S. Dep’t of Justice, 
    823 F.2d 574
    , 587 (D.C. Cir. 1987) (quoting Coastal 
    States, 617 F.2d at 865
    ). As is the case for all parts of Exemption 5, this privilege is to be read narrowly.
    See 
    id. at 584
    (“Congress intended to confine exemption (b)(5) ‘as narrowly as [is] consistent
    with efficient Government operation.’” (quoting Coastal 
    States, 617 F.2d at 868
    )). And again, as
    is the case for all FOIA exemptions, the agency seeking to invoke the exemption must “establish
    [its] right to withhold evidence from the public,” Coastal 
    States, 617 F.2d at 861
    , and must carry
    this burden with a “relatively detailed justification” of its application of the privilege. Elec.

    Ctr., 192 F. Supp. 3d at 103
    (quoting Mead Data Cent., 
    Inc., 566 F.2d at 251
    ).
    24
    Because Army’s application of Exemption 5 involves various combinations of the
    privileges available to it under this exemption, the Court will begin with the simplest case—the
    contested documents that involve only the deliberative process privilege—and then proceed to
    Army’s other privilege claims.
    2. Defendant Army’s Claims of Deliberative Process Privilege
    Army withholds twenty-two of the challenged documents in full or in part under only the
    deliberative process privilege. 13 The majority of these documents are draft documents and
    surrounding agency discussion thereof, including email exchanges. A handful involve the
    agency’s formulation of external communications and publicity plans. In a vacuum, these are the
    sorts of documents that reflect an agency’s deliberative process and thus fall within the scope of
    the privilege. See, e.g., Reliant Energy Power Generation, Inc. v. Fed. Energy Regulatory
    Comm’n., 
    520 F. Supp. 2d 194
    , 204 (D.D.C. 2007) (“An agency may withhold a draft document
    if there is a danger of ‘chilling’ communication within the agency” (quoting Dudman
    
    Commc’ns, 815 F.2d at 1569
    )); Competitive Enter. Inst. v. EPA., 
    12 F. Supp. 3d 100
    , 118
    (D.D.C. 2014) (applying privilege to documents that reflect “ongoing decisionmaking about how
    the agency’s activities should be described to the general publics” (quoting Nat’l Sec. Archive v.
    Fed. Bureau of Investigation, No. 88-1507, 
    1993 WL 128499
    , at *2 (D.D.C. Apr. 15, 1993));

    , at *4 (D.D.C. Aug. 18, 1997)
    (permitting agency to withhold information related to its determination of what to disclose to the
    media). That said, in practice, the deliberative process privilege is highly context-specific: the
    13
    These documents, which the Court identified based on the Revised Updated Army
    Vaughn Index, see Defs.’ Mem. P. &. A. Opp’n Pls.’ Cross Mot. Partial Summ. J. (“Defs.’ Mem.
    P. & A. Opp’n”) Ex. 1, ECF No. 99-2, are: Army 15, Army 16, Army 20, Army 22, Army 25,
    Army 26, Army 39, Army 46, Army 54, Army 62, Army 63, Army 64, Army 67, Army 71,
    Army 72, Army 82, Army 83, Army 84, Army 85, Army 87, Army 97, and Army 105.
    25
    propriety of its application is “dependent upon the individual document and the role it plays in
    the administrative process.” Elec. Frontier Found. v. U.S. Dep’t of Justice, 
    826 F. Supp. 2d 157
    ,
    167–68 (D.D.C. 2011) (quoting Animal Legal Defense Fund, Inc. v. Dep’t of the Air Force, 44 F.
    Supp. 2d 295, 299 (D.D.C. 1999)); see also Coastal 
    States, 617 F.2d at 867
    . To carry its burden
    regarding the privilege, then, Army must provide a “relatively detailed justification” for each of
    the documents that contextualizes how the withheld information relates to a policy-oriented
    decisionmaking process. Mead Data Cent., 
    Inc., 566 F.2d at 251
    .
    Many of Army’s deliberative process claims concerning draft documents and associated
    communications provide the requisite justification. The agency’s drafts and deliberations around
    Army Field Manual 2-22.3 (“FM 2-22.3”) are illustrative. 14 Army has withheld in full four draft
    versions of FM 2-22.3 or its appendices: Army 15, Army 16, Army 20, and Army 22. Defs.’
    Mem. P. & A. Opp’n Ex. L, Second Declaration of Major John E. Swords (“Second Swords
    Decl.”) ¶ 10a. The Second Swords Declaration establishes that each of these drafts was
    produced before FM 2-22.3’s adoption, 
    id., which makes
    them predecisional. See Access
    
    Reports, 926 F.2d at 1195
    (quoting Taxation with Representation Fund, 
    646 F.2d 666
    , 677 (D.C.
    Cir. 1981), for the proposition that “[p]redecisional documents are thought generally to reflect
    the agency ‘give-and-take’ leading up to a decision that is characteristic of the deliberative
    process” (emphasis in original)). In addition, the agency’s revised updated Vaughn Index, see
    ECF No. 99-2, provides adequate detail to identify “a policy-oriented decisionmaking process to
    which the draft contributed,” Bloche 
    II, 370 F. Supp. 3d at 51
    . For instance, the entry for Army
    15 establishes that the document at issue is a “draft policy appendix, with comments, addressing
    a particular restricted interrogation technique,” and states that the agency withheld it in full
    14
    As the Court addresses below, this is not the case for Army 25 and Army 26, which
    also involve FM 2-22.3, but which the Army has been unable to locate in an unredacted form.
    26
    because of its draft status and the fact that it contains “comments which include
    recommendations and opinions regarding legal and policy matters.” 15 Revised Updated Army
    Vaughn Index 1. Given this draft’s status as part of the decisionmaking process around how to
    develop the new FM 2-22.3, see Second Swords Decl. ¶¶ 7, 10a, this material is deliberative and,
    hence, privileged. The same is true of the four drafts of FM 2-22.3 and its appendices, 16 see
    Revised Updated Army Vaughn Index 1–2, as well as Army 46, an email chain and attached
    15
    Although the entries for the other drafts repeat similar or even identical language, this
    repetition is logical when, as here, all of the drafts relate to the agency’s formulation of the same
    policy proposal. As such, repetition alone does not make the text the sort of conclusory, rote
    assertion that fails to satisfy Exemption 5’s demands. This Circuit’s law “ha[s] never required
    repetitive, detailed explanations for each piece of withheld information.” Judicial Watch, Inc. v.
    Food & Drug Admin., 
    449 F.3d 141
    , 147 (D.C. Cir. 2006) (citing Keys v. U.S. Dep’t of Justice,
    
    830 F.2d 337
    , 349–50 (D.C. Cir. 1987)). Rather, “[e]specially where”—as is the case here—“the
    agency has disclosed and withheld a large number of documents, categorization and repetition
    provide efficient vehicles by which a court can review withholdings that implicate the same
    exemption for similar reasons.” Id.; see also Am. Immigration Council v. U.S. Dep’t of
    Homeland Sec., 
    950 F. Supp. 2d 221
    , 236–37 (D.D.C. 2013) (“[T]he government need not
    furnish repetitive descriptions of the same type of document and may describe commonalities
    among its withholdings” (citing Judicial 
    Watch, 449 F.3d at 147
    )).
    16
    Although Plaintiffs challenge the withholding of Army 20 on the grounds that this
    document is labeled as a “working version,” Pls.’ Reply 18–19, the mere designation of this
    document as a “draft/working version,” see Revised Updated Army Vaughn Index 1, does not
    compel the conclusion that the agency must disclose it in full. Without more firm evidence to
    suggest that the draft was in fact “informally adopted,” Pls.’ Reply 19, “as the agency position on
    an issue” in a manner that would defeat the claim of privilege, Judicial Watch v. U.S. Postal
    Serv., 
    297 F. Supp. 2d 252
    , 261 (D.D.C. 2004) (quoting Arthur Andersen & Co. v. Internal
    Revenue Serv., 
    679 F.2d 254
    , 257 (D.C. Cir. 1982), there is no reason to discredit the agency’s
    statement that the draft preceded and contributed to the development of the final version, see
    Swords Decl. ¶ 7, and thereby played a role in that policy-oriented decision-making process in a
    manner that justifies its privileged status. Without more concrete evidence, the Court will not
    infer that the agency adopted a position taken in a draft as a final decision in a way that requires
    disclosure. See Trans Union LLC v. Fed. Trade Comm’n, 
    141 F. Supp. 2d 62
    , 70–71 (D.D.C.
    2001) (concluding that, “where it is unclear whether” initial input from the agency provided the
    basis for its final output, the input “is exempt from disclosure” (citing Renegotiation Bd. v.
    Grumman Aircraft Eng’g Corp., 
    421 U.S. 168
    , 184–185 (1975)). Nor, despite Plaintiffs’
    argument, must the agency demonstrate the extent to which a draft differs from the final
    document—which would itself expose its deliberative process. See Reliant Energy, 
    520 F. Supp. 2d
    at 204 (quoting Exxon Corp. v. Dep’t of Energy, 
    585 F. Supp. 690
    , 698 (D.D.C. 1983)).

    draft policy on “Gap Analysis, Behavioral Science Consultation [‘BSC’] to Interrogation and
    Detention Operations” that is “annotated with notes, comments, and questions posed by various
    personnel during coordination of the [BSC] policy,” 
    id. at 9.
    17
    So, too, do the agency’s justifications suffice when it comes to many of the internal
    communications surrounding its development of not only FM 2.22-3, but also other agency
    policies. Take Army 72, which consists of an email chain with an attached draft PowerPoint that
    was prepared for a “Familiarize Brief” on the proposed FM. See Revised Updated Army Vaughn
    Index 23. The agency has “redacted portions of [the] email regarding recommended changes to
    [the] [P]ower[P]oint brief,” which is withheld in full. 
    Id. Although Army
    would, ideally, speak
    with more precision to define the purpose and expectations of a “Familiarize Brief,” the material
    provided logically indicates that the PowerPoint is a draft briefing document and that the email
    chain contains “recommended changes” to it. 
    Id. By indicating
    the context (development of the
    agency’s position concerning the FM) for which the material was produced, Army has amply
    “‘identif[ied the decisionmaking process’ to which the withheld documents contributed.” Elec.
    Frontier Found. v. U.S. Dep’t of Justice, 
    890 F. Supp. 2d 35
    , 52 (D.D.C. 2012) (emphasis in
    original) (quoting 
    Sears, 421 U.S. at 150
    ). Army has thus established how releasing the withheld
    materially could logically and plausibly chill agency deliberations concerning the draft FM,
    17
    Plaintiffs contest the withholding of this document at some length, challenging, in
    particular, Defendants’ assertion that “the Gap Analysis was never finalized and is therefore
    exempt” on the grounds that “a gap analysis typically compares . . . proposed policy and current
    policy,” such that “even a non-finalized gap analysis would contain” unprivileged “information
    about current policy.” Pls.’ Reply 18. But this contestation as to whether the agency segregated
    non-privileged material in the document is a different issue from whether the privilege applies to
    the document at all, and Plaintiffs fail to present any independent reason to believe that this draft
    policy memoranda and the surrounding communication about it are not properly part of Army’s
    deliberative process.
    28
    thereby undermining the purpose of the privilege. 18 See 
    Scudder, 254 F. Supp. 3d at 140
    (quoting Judicial 
    Watch, 715 F.3d at 941
    ). Army provides similar, if not more detailed,
    justification for its application of the privilege to other email chains concerning other developing
    agency policies. As an illustration of a particularly detailed description, consider Army 39,
    which the agency has explained consists of two emails exchanged in February 2005 and
    December 2004 “between a Womack Army Medical Center Doctor and various Army doctors”
    that consist, respectively, of the “notes on a meeting with a Special Operations Command
    Clinical Psychologist and his opinions and recommendations on the presence of psychologists
    during interrogations” and a message “sent by the Director of the Psychological Applications
    Directorate of the Army’s Special Operations Command to a[] Special Operations Command
    employee enumerating his opinions and recommendations regarding what the mission objectives
    should be for psychologists providing support to detainee operations.” Revised Updated Army
    Vaughn Index 6.
    Although Army provides slightly less detail, it has also adequately justified its redactions
    for most of its other applications of the privilege. The majority of these applications are partial
    withholdings in email chains concerning the “logistics of coordinat[ing] review of” a “Proposed
    SecDef Memo on Ethics Principles and Procedures for Detainees,” 
    id. at 20
    (discussing Army
    67); see also 
    id. at 23
    (similar description for Army 71), “seeking advice and assistance” from
    agency attorneys “on tracking of investigations based on allegations of improper behavior in
    18
    Plaintiffs do not directly contest this conclusion, but instead argue that the PowerPoint
    is “extremely likely” to “contain factual information and information on current policies in order
    to contextualize the proposed changes,” which “must be segregated out” and released. Pls.’
    Mem. 28. But again, the question of whether the agency has met its burden to release all
    reasonably segregable, non-exempt material is a distinct issue from whether the material is
    properly privileged, and hence exempt, in the first instance. The Court discusses segregability
    below.

    relation to detainee operations,” 
    id. at 30
    (discussing Army 82); “addressing concerns raised by
    DOD” about a draft Army document, the “Interim Guidance on Detainee Medical Care,” 
    id. at 31
    (discussing Army 83); see also 
    id. (similar description
    for Army 84); 
    id. at 32
    (similar
    description for Army 85), 19 and an email chain between attorneys “addressing proposed changes
    to AR 190-8 and the legal implications of some of the proposed changes,” 
    id. at 34
    (discussing
    Army 87). For these documents, Army details between which parties the emails were sent,
    establishes that the emails contain opinions and recommendations, and discusses the relationship
    between the email and a particular policy development process, thereby adequately supporting its
    invocation of the privilege. The same is true of the email chains with attachments. See, e.g., 
    id. at 15
    (discussing Army 54, a partially redacted email and attachment concerning Final
    Coordination on DoD Instruction 2310.kk, including a fully withheld comment matrix with
    proposed edits);

    “discussing legal opinions on a draft policy memo on Medical Ethics Principles and Procedures
    for the Protection and Treatment of Detainees in the Custody of the Armed Forces of the United
    19
    Plaintiffs object that these documents cannot be shielded because Army “largely relies
    on ‘boilerplate language’ to justify its withholdings,” asserting that “Defendants have
    consistently failed to identify ‘the nature of the decisionmaking authority vested in the
    document’s author and recipient’” and instead relied on inadequate “broad conclusory
    statements.” Pls.’ Reply 21 (first quoting Hunton & Williams LLP v. U.S. Envtl. Protection
    Agency, 
    346 F. Supp. 3d 61
    , 74 (D.D.C. 2018), then citing Mead Data Cent., 
    Inc., 566 F.2d at 258
    ). But mere repetition with regard to more than one document, which Plaintiffs characterize
    as “boilerplate” language, is not necessarily the sort of conclusory justification that falls short of
    FOIA’s demands. The relevant question is whether the agency has established how the
    documents at issue relate to the formulation of the agency’s policy. If the policy is the same in
    more than one instance, then it is logical that the agency’s justification would also be similar.
    On the description provided, it is sufficiently clear that the challenged documents involved
    recommendations offered up as part of a particular deliberative process. See Nat’l Sec. 
    Archive, 752 F.3d at 463
    (applying privilege where it is clear that “the communication is intended to
    facilitate or assist development of the agency’s final position on the relevant issue.”). Thus, the
    privilege is justified.
    30
    States,” with the draft policy memo redacted in full). The redacted portions of these documents
    are thus privileged.
    The remaining challenged documents involve the agency’s development of its position
    concerning FM 2-22.3 or its internal discussions concerning other agency policies. Some of
    these documents provide the “relatively detailed” justification required to apply the privilege.
    Army 62 is illustrative of an adequate justification. This document consists of a “[d]raft
    communications plan prepared by the Army’s office of the Chief of Public Affairs for [the]
    purpose of developing a media and public affairs strategy for the issuance of the FM.” Revised
    Updated Army Vaughn Index 17. The agency makes clear that this “draft communications plan .
    . . was prepared to assist the Army in navigating the significant public interest in detainee
    interrogation methods by proposing a media and public affairs strategy for announcing” the
    FM’s “upcoming issuance.” Second Shields Decl. ¶ 10. This description sufficiently establishes
    that the document played a role in Army’s decisionmaking about how to communicate the
    developing policy to the public, see Competitive Enter. 
    Ins., 12 F. Supp. 3d at 118
    (quoting Nat’l
    Sec. Archive, 
    1993 WL 128499
    , at *2), such that it is privileged. Along similar lines, Army
    provides sufficient justification to withhold in part Army 105, which consists of “notes prepared
    by attorneys for senior Army personnel in order to assist in their preparation for addressing a
    [c]ongressional committee regarding the Common Article 3 Executive Order.” Revised Updated
    Army Vaughn Index 43. The agency clarifies that the relevant deliberative process at issue is
    Army’s decision about “what information should be provide to Congress” and specifies that the
    “list of talking points reflects internal deliberations regarding what information” to provide. 
    Id. But Army’s
    other privilege claims are insufficiently supported. Consider Army 63 and
    Army 64, which both consist of “questions and answers in draft form addressing various Army
    31
    concerns or points of clarification about the new Army FM 2-22.3.” Revised Updated Vaughn
    Index 18. The agency states that these draft questions and answers addressed “the Army’s
    forthcoming issuance of the FM” and were “prepared for decision makers to address various
    concerns and points of clarification with the proposed FM.” Second Shields Decl. ¶ 10.
    However, Army never identifies or describes which decisionmakers were targeted, nor does it
    state what sorts of concerns or points of clarification were involved with any particularity.
    Without more to contextualize the agency’s development of and subsequent reliance on—or lack
    thereof—the reasoning in these documents, the Court cannot be certain that these documents
    entail predecisional “formulation or exercise of . . . policy-oriented judgment.” Bloche II, 370 F.
    Supp. 3d at 54 (quoting Prop. of the 
    People, 330 F. Supp. 3d at 382
    (emphasis in original)); see
    also Petroleum Info. 
    Corp, 976 F.2d at 1435
    .
    Nor has Army adequately justified its withholding in full of four documents, Army 25,
    Army 26, Army 112, and Army 113, all of which it seeks to shield in full pursuant to Exemption
    5’s deliberative process privilege. 20 Because Army cannot locate unredacted versions of these
    four documents, 21 it “relies on its prior Exemption 5 determination,” reached in 2008, “for
    purposes of this motion.” Swords Decl. ¶ 5 n.2. The problem with this reliance, however, is that
    20
    Army states that it withholds Army 25 and Army 26 “as deliberative process,” Revised
    Updated Army Vaughn Index 3, but does not specifically mention deliberative process privilege
    for Army 112 or 113. See 
    id. at 45.
    The Court infers that this is the privilege on which Army
    relies based on its assertion that the documents are “[f]ully exempt under (b)(5)” “given their
    [status as] classified, deliberative and advisory documents prepared prior to an agency decision”
    and the fact that they “include[] recommendations or express opinions on legal and policy
    matters before the Department of the Army.” 
    Id. If Army
    intends to invoke attorney-client
    privilege in addition to or in lieu of deliberative process privilege, then it must explicitly do so.
    21
    As previously noted, although Plaintiffs’ reply brief contests the adequacy of Army’s
    search for these four missing documents, see Pls.’ Reply 2, Plaintiffs waived this argument given
    the failure to develop this objection until this late stage, apart apart from a passing reference in a
    footnote in its opening brief. See Sitka Sound Seafoods, 
    Inc., 206 F.3d at 1181
    . Thus, the Court
    considers only the Army’s application of exemptions to these four documents.
    32
    the agency has not “describe[d] the requested documents and ‘the justifications for nondisclosure
    with reasonably specific detail.’” Pronin, 
    2019 WL 1003598
    , at *3 (quoting 
    Larson, 565 F.3d at 862
    ). The agency’s 2008 declaration does not speak to these documents at all, instead focusing
    primarily on the search that Army originally conducted. See Defs.’ Mot. Partial Summ. J. Ex. B-
    1, Declaration of Lisa M. Satterfield, ECF No. 96-3. Nor do Army’s 2018 declarations provide
    any justification for nondisclosure of these four documents. 22 This showing does not establish
    that the documents are privileged in their entirety. To be sure, Army does describe the nature of
    the documents with reasonable specificity. For instance, Army 25 is a draft appendix to the draft
    FM 2-22.3 that “addresses restricted interrogation approach techniques.” Revised Updated
    Army Vaughn Index 3; see also 
    id. (same justification
    for Army 26). And Army 112 is a
    memorandum with the subject “Final Report and Recommendations to Assess the Legal, Policy,
    and Operational Issues Relating to Interrogation of Detainees Held by the U.S. Armed Forces
    (2/11/2003). 
    Id. at 45;
    see also 
    id. (describing Army
    113 as memorandum that contains the
    Judge Advocate General’s legal opinions on the Department of Justice’s stance regarding
    “current and significant operational law issues” for “enemy combatants held at Guantanamo
    Bay”). But given that Army does not have access to the unredacted document, this description
    alone cannot justify its withholding in full. Army has not presently provided any justification for
    withholding the unredacted portions, and this lack of justification gives it “no standing to invoke
    exemptions.” Piper v. U.S. Dep’t of Justice, 
    294 F. Supp. 2d 16
    , 32 (D.D.C. 2003), amended,
    
    428 F. Supp. 2d 1
    (D.D.C. 2006), aff’d sub nom. Piper v. U.S. Dep’t of Justice, 222 F. App’x 1
    (D.C. Cir. 2007). The fact “that the Government can no longer locate the file” in unredacted
    22
    The original Swords Declaration speaks solely to the “thorough and exhaustive search”
    that Army conducted to attempt to locate the documents, Swords Decl. ¶ 3 n.1, and the Second
    Swords Declaration, see ECF No. 99-2, does not discuss them at all.
    33
    form “does not give it license to withhold information with the caveat that it could not track
    down the documents when challenged.” 
    Id. Army must,
    accordingly, describe in “reasonably
    specific” detail how all of the withheld portions relate to a particular deliberative process. Until
    such time, Army has not established that Army 25, 26, 112, and 113 are properly shielded under
    the deliberative process privilege.
    In sum, then, the Court grants Defendants’ motion for summary judgment with respect to
    all of their deliberative process privilege claims, with the exception of the six documents
    identified in the preceding discussion: Army 25, Army 26, Army 63, Army 64, Army 112, and
    Army 113. As the Court explained in Bloche II, where, as here, “an agency fails to meet its
    burden, FOIA provides courts ‘a host of procedures’ to determine whether the exemption claim
    is proper, including discovery, further agency affidavits, and in camera review of the records in
    
    question.” 370 F. Supp. 3d at 55
    (quoting Allen v. Cent. Intelligence Agency, 
    636 F.2d 1287
    ,
    1298 (D.C. Cir. 1980), abrogated on other grounds by Founding Church of Scientology of
    Wash., D.C., Inc. v. Smith, 
    721 F.2d 828
    , 830–31 (D.C. Cir. 1983)). In general, “a district court
    should not undertake in camera review of withheld documents as a substitute for requiring an
    agency’s explanation of its claimed exemptions.” 
    Spirko, 147 F.3d at 997
    . Nonetheless, “in
    camera inspection may be particularly appropriate . . . when the number of withheld documents
    is relatively small.” 
    Id. at 996
    (internal quotation marks omitted)); see also Gatore v. U.S. Dep’t
    of Homeland Sec., 
    292 F. Supp. 3d 486
    , 495 (D.D.C. 2018) (finding in camera review the “most
    efficient means” of resolving an issue “given the small number of documents at issue);
    Physicians for Human Rights v. Dep’t of Def., 
    675 F. Supp. 2d 149
    , 167 (D.D.C. 2009)
    (quoting 
    Allen, 636 F.2d at 1298
    ) (same). In this instance, given the relatively small number of
    documents at issue, the Court finds further agency supplementation along with in camera review
    34
    of the documents to be the most expeditious resolution. Thus, Army must provide these
    materials to the Court along with updated justifications for its claims of deliberative process
    privilege, either in the form of new declarations or a revised Vaughn index, see Vaughn v. Rosen,
    
    484 F.2d 820
    , 826–28 (D.C. Cir. 1973), whereupon it may, if it continues to apply deliberative
    process privilege to the contested documents, submit a renewed motion for summary judgment.
    3. Defendant Army’s Claims of Attorney-Client Privilege
    Army relies on another part of Exemption 5, the attorney-client privilege, to withhold in
    part Army 80 and to withhold in full Army 96. Unlike the documents discussed below, for
    which Army invokes both attorney-client privilege and another privilege, the attorney-client
    privilege is the sole basis for these redactions. Plaintiffs challenge both of these withholdings,
    contending that Army’s updated declaration, see Second Swords Decl., still fails to establish
    “how or why these records were meant to be confidential or whether they were actually kept
    confidential,” Pls.’ Reply 12. Although Plaintiffs are correct that the agency claiming attorney-
    client privilege must show confidentiality and thereby demonstrate that the privilege is
    applicable, see Mead Data Cent., 
    Inc., 566 F.2d at 254
    , for the reasons set forth below, Army has
    carried its burden for both of the challenged documents.
    Army 80 and Army 96 consist of emails dated July 6, 2005, and July 7, 2005,
    respectively, on the same topic. Each document is described in Army’s Vaughn Index as an
    “[e]mail from a [Department of the Army] Office of the General Counsel Attorney to an Office
    of Congressional Legal Liaison member addressing legal concerns raised by the DoD with
    respect to the Army’s position on the treatment of detainees, as well as recommendations as to
    how the DoD’s legal concerns should be incorporated into [c]ongressional briefings.” Revised
    Updated Army Vaughn Index 29, 41. Army 96 includes “the sole email comprising Document
    35
    80, as well as two additional emails between the same individuals with the Senior Deputy
    General Counsel cc’d” that “contain opinions and recommendations regarding the inclusion of
    specific information in a briefing for the Secretary of Defense.” Second Swords Decl. ¶ 9b(ii).
    For both documents, Army redacted portions of the email communications, which the agency
    states were “made in confidence,” with “no record of that confidentiality being compromised in
    the intervening years.” Second Swords Decl. ¶¶ 9b(i)–(ii); see also Revised Updated Army
    Vaughn Index 29, 41.
    With this combination of the Vaughn Index and its declarations, Army has adequately
    justified its application of the privilege. Because the attorney-client privilege “protects
    communications from attorneys to their clients if the communications ‘rest on confidential
    information obtained from the client,’” Tax 
    Analysts, 117 F.3d at 618
    (quoting In re Sealed 
    Case, 737 F.2d at 98
    –99), and this was a communication in which an Army attorney conveyed her
    position on “legal concerns” regarding an agency position to an agency client, Army has
    established that this is the sort of communication that the privilege protects. See also In re
    Kellogg Brown & Root, Inc., 
    756 F.3d 754
    , 757 (D.C. Cir. 2014) (“[T]he [attorney-client]
    privilege applies to a confidential communication between an attorney and client if that
    communication was made for the purpose of obtaining or providing legal advice to the client.”).
    Moreover, Army’s description carries its burden to “demonstrate that confidentiality was
    expected in the handling of these communications, and that it was reasonably careful to keep this
    confidential information protected from general disclosure.” Coastal 
    States, 617 F.2d at 863
    .
    Plaintiffs’ contrary argument is misguided. Army explicitly states that the communications were
    made in confidence. See Second Swords Decl. ¶ 9b(i). And the Court credits the sworn
    statement that there is “no record of” “confidentiality being compromised,” 
    id., as adequate
    36
    evidence that they were in fact maintained internally and not divulged in a manner that would
    compromise confidentiality. In short, there is no reason, based on the evidence Plaintiffs offer,
    to question the confidentiality of the communication. See Hunton & Williams, LLP, 248 F.
    Supp. 3d at 256 (affirming agency’s attorney-client privilege claim where there was no indicia
    that the documents were distributed to outside entities). The redacted portions of Army 80 and
    Army 96 are, accordingly, privileged and appropriately withheld.
    4. Defendant Army’s Overlapping Privilege Claims
    The remainder of the documents that Army has withheld in full or in part pursuant to
    Exemption 5 involve more than one privilege claim. The Court will first assess Army’s
    overlapping attorney-client and attorney work product privilege claims before turning to its
    overlapping deliberative process and attorney-client privilege claims. For the reasons set forth
    below, Army has justified only a few of its withholdings in these categories based on the
    material provided.
    a. Attorney-Client Privilege and Attorney Work Product Privilege
    Army has applied both attorney-client and attorney work product privilege to three
    contested documents: Army 81, Army 95, and Army 111. Again, the purpose of each of these
    privileges is distinct. See Coastal 
    States, 617 F.2d at 864
    . The attorney-client privilege, as the
    Court just discussed, “protects confidential communications from clients to their attorneys made
    for the purpose of securing legal advice or services” as well as “communications from attorneys
    to their clients if the communications ‘rest on confidential information obtained from the
    client.’” Tax 
    Analysts, 117 F.3d at 618
    (quoting In re Sealed 
    Case, 737 F.2d at 98
    –99). The
    narrower attorney work product privilege “shields materials ‘prepared in anticipation of litigation
    or for trial by or for [a] party or by or for that . . . party’s representative.’” 
    Id. at 620
    (quoting
    37
    Fed. R. Civ. P. 26(b)(3)). Plaintiffs make two general arguments regarding these documents:
    Army’s justifications for attorney-client privilege are conclusory, and Army’s justifications for
    attorney work product privilege fail to establish that the documents were prepared in anticipation
    of litigation. Pls.’ Reply 12–13; see also Pls.’ Mem. 35. For the reasons set forth below, Army
    has adequately justified its application of the work product privilege to Army 95 and the
    attorney-client privilege to Army 81, but its submissions are insufficient to justify its withholding
    in full of Army 111.
    Two of the contested documents, Army 95 and Army 81, are email communications
    concerning allegations of improper behavior in detainee operations, detainee abuse, and
    associated investigations. See Revised Updated Army Vaughn Index 31, 40. Army details the
    investigation at issue in Army 95: this document consists of “an email chain beginning with a
    request to several agency directorates and their counsel from Major General George Fay for
    assistance with answering a follow-up question to his investigative findings and
    recommendations regarding allegations of detainee abuse at Abu Ghraib that were lodged against
    specifically identified U.S. soldiers.” Second Swords Decl. ¶ 9b(iv). Army states that the
    redacted portions of the email chain involve “agency counsel’s legal opinions and
    recommendations regarding the possibility of criminal prosecutions as a result” of the
    investigation. 
    Id. These statements
    suffice to establish that this document qualifies for work product
    privilege. Plaintiffs are correct that the bare prospect that “litigation might someday occur” is
    too insubstantial a ground to justify invocation of this privilege. Senate of the Commonwealth of
    
    Puerto Rico, 823 F.2d at 587
    . That said, “Exemption 5 extends to documents prepared in
    anticipation of foreseeable litigation, even if no specific claim is contemplated.” Schiller, 
    964 38 F.2d at 1208
    (citing Delaney, Migdail & Young, Chartered v. Internal Revenue Serv., 
    826 F.2d 124
    , 127 (D.C. Cir. 1987)). The relevant standard is whether the government’s attorney
    “prepared a document in the course of an investigation that was undertaken with litigation in
    mind.” Boyd v. Executive Office for United States Attorneys, 
    87 F. Supp. 3d 58
    , 84 (D.D.C.
    2015) (quoting Safecard Servs., Inc. v. Sec. & Exch. Comm’n, 
    926 F.2d 1197
    , 1202 (D.C. Cir.
    1991)); see also Agility Public Warehousing Company K.S.C. v. Department of Defense, 110 F.
    Supp. 3d 215, 228 (D.D.C. 2015) (“The work-product doctrine is not limited to those cases
    where litigation is a foregone conclusion.”). The key question is whether litigation is foreseeable
    by the individual who prepared the document, at the time that it was prepared: “[f]or a document
    to meet [the anticipation-of-litigation] standard, the lawyer must at least have had a subjective
    belief that litigation was a real possibility, and that belief must have been objectively
    reasonable.” Agility Public Warehousing Company 
    K.S.C., 110 F. Supp. 3d at 228
    (emphasis in
    original) (quoting In re Sealed 
    Case, 146 F.3d at 884
    ). Here, Army has pointed to a specific
    investigative proceeding, involving a specific individual in the Army, concerning “the possibility
    of criminal prosecutions as a result of the investigation.” Second Swords Decl. ¶ 9b(iv). It has
    further stated that the redacted portions reflect the agency counsel’s communications regarding
    the possible criminal prosecutions, establishing that the counsel knew of the “real possibility” of
    litigation at the time that he wrote. This specification thus carries the agency’s burden, and
    Army may withhold portions of Army 95 pursuant to the work product privilege. 23
    But similar specificity is lacking for Army 81. For this document, the withheld material
    23
    Because “the protection offered by the [work product] doctrine ‘is broader than the
    attorney-client privilege in that it is not restricted solely to confidential communications between
    an attorney and client,” Agility Pub. Warehousing Co. 
    K.S.C., 110 F. Supp. 3d at 227
    (quoting
    Fed. Trade Comm’n v. Boehringer Ingelheim Pharms., Inc., 
    778 F.3d 142
    , 149 (D.C. Cir. 2015)),
    the Court will not assess Defendants’ claim that attorney-client privilege also applies to Army
    96.
    39
    appears in an email “from an attorney in the Department of Defense’s Office of General Counsel
    to an attorney in the Department of the Army’s Office of General Counsel seeking assistance
    with tracking investigations into allegations of detainee mistreatment and recommendations for
    how to respond to anticipated legal questions and possible litigation.” Second Swords Decl. ¶
    9b(iii) (emphasis added). Rather than identify a particular investigative proceeding, Army relies
    on generalities coupled with the statement that “[c]ounsel anticipated the possibility of
    litigation.” 
    Id. But there
    is a difference between “possible litigation,” 
    id., and the
    “foreseeable
    litigation” that the law demands to claim the privilege, 
    Schiller, 964 F.2d at 1208
    . And in this
    instance, Army has not indicated in a nonconclusory fashion the investigative context that would
    establish a “real possibility” of litigation, Agility Public Warehousing Company K.S.C., 110 F.
    Supp. 3d at 228 (emphasis omitted) (quoting In re Sealed 
    Case, 146 F.3d at 884
    ), at the time that
    the attorney prepared the material. Thus, without greater detail to establish more than the
    concern that “litigation might someday occur,” Senate of the Commonwealth of 
    Puerto Rico, 823 F.2d at 587
    , Army cannot rely on work product doctrine to withhold Army 81.
    That said, the justification provided does permit the agency to partially withhold Army 81
    pursuant to attorney-client privilege. Army’s Vaughn Index specifies that the redacted portions
    of the document “reflect advice that was being sought as well as the recommendations provided”
    by the agency’s counsel. Revised Updated Army Vaughn Index 31. Thus, this communication is
    clearly one “between an attorney and his client relating to a legal matter for which the client has
    sought professional advice.” Mead Data Cent., 
    Inc., 566 F.2d at 252
    . In addition, Army affirms
    that the material was confidential, and that confidentiality has been preserved. See Second
    Swords Decl. ¶ 9b(iii) (“The legal opinions and recommendations withheld in Document 81 were
    made in confidence between agency counsel and their clients and have subsequently remained
    40
    confidential.”). This statement, in conjunction with the entry in its Vaughn Index and the
    description of the communication’s purpose in the declaration, carries Army’s burden to
    “demonstrate that confidentiality was expected in the handling of these communications,”
    Coastal 
    States, 617 F.2d at 863
    , and as such, Army has adequately justified its application of the
    privilege.
    However, Army has not similarly justified its withholding in full of Army 111. Army
    cannot rely on the attorney work product privilege here for the same reason that its justification
    falls short with respect to Army 81: the prospect of litigation is not sufficiently clear. In
    discussing Army 111, Army does not identify any specific investigation, but instead states that
    the “draft memorandum” “provides legal analysis, opinions, and recommendations regarding the
    adoption of certain detainee interrogation techniques being considered by the Department of
    Defense,” and which the author, the Judge Advocate General, “anticipates will potentially be
    subject to litigation in both international and domestic forums.” Second Swords Decl. ¶ 9a. As
    with Army 81, this speculative future prospect of possible litigation, without more, does not
    suffice to establish that material is privileged pursuant to the work product doctrine. And unlike
    Army 81, Army cannot fall back on attorney-client privilege to withhold the document in full.
    As stated previously, the attorney-client privilege is narrower than work product doctrine in the
    sense that it covers only “confidential communications between an attorney and a client.” Agility
    Pub. Warehousing Co. 
    K.S.C., 110 F. Supp. 3d at 227
    (quoting Boehringer Ingelheim Pharms.,
    
    Inc., 778 F.3d at 149
    ). But here, neither the declaration nor the Vaughn Index states that all the
    withheld portions of the document involve confidential attorney-client “communications”
    “relating to a legal matter,” Mead Data Cent., 
    Inc., 566 F.2d at 252
    , and as such, Army has not
    adequately justified its withholding.
    41
    The Court thus finds the application of attorney-client privilege proper for Army 81 and
    Army 95, but finds Army’s explanation inadequate for Army 111. In this case, the Court
    exercises its “broad discretion” regarding how best to redress Army’s failure to meet its burden
    by ordering updated justification for Army 111, 
    Allen, 636 F.2d at 1298
    , which Army may
    submit either in the form of new declarations or a revised Vaughn index, see 
    Vaughn, 484 F.2d at 826
    –28. 24
    b. Deliberative Process Privilege and Attorney-Client Privilege
    For the remaining forty documents, Army justifies its withholdings pursuant to both the
    deliberative process privilege and the attorney-client privilege. 25 Army re-reviewed these
    documents before releasing its most recent Vaughn Index. See Second Swords Decl. ¶ 8. In
    support of its deliberative process claim, Army affirms that “[t]hese documents reflect the advice
    that was sought, and the opinions and recommendations that were given, regarding proposed
    policies and draft policy documents.” 
    Id. And in
    support of its attorney-client privilege claim,
    Army offers that “Army attorneys evaluated the proposed polices, reviewed the drafts they
    received, and provided their legal analysis, reviews, opinions and recommendations,” which
    were “made in confidence and were not subsequently shared with individuals outside of the
    attorney-client relationship.” 
    Id. Defendants present
    any such overlap as unproblematic,
    24
    To the extent that Army continues to rely on attorney work product privilege, it must
    provide more concrete detail about the litigation context for which the document was prepared.
    To the extent that Army rests instead on attorney-client privilege, it must indicate with greater
    precision why this privilege alone shields the document in full, including further detail
    concerning the confidentiality of the material within it. To the extent that Army relies on both
    privileges, it must indicate any portions of the document for which application of the privilege is
    not coterminous.
    25
    These documents are: Army 21, Army 24, Army 34, Army 40, Army 41, Army 42,
    Army 43, Army 44, Army 45, Army 47, Army 48, Army 49, Army 50, Army 51, Army 52,
    Army 55, Army 56, Army 65, Army 66, Army 69, Army 70, Army 73, Army 74, Army 75,
    Army 76, Army 77, Army 78, Army 79, Army 86, Army 88, Army 89, Army 90, Army 91,
    Army 92, Army 93, Army 94, Army 98, Army 99, Army 107, Army 109.
    42
    asserting that “‘the Court need not decide whether the[se] documents were [] properly withheld
    under the attorney-client privilege[,]’ because the Army sufficiently demonstrated that they also
    properly withheld the information under the deliberative process privilege.’” Defs.’ Mem. P. &
    A. Opp’n 26 n.5 (quoting Judicial Watch v. U.S. Dep’t of Justice, 
    20 F. Supp. 3d 260
    , 276
    (D.D.C. 2014)). Plaintiffs see it differently, contending both that the overlap matters because
    attorney-client privilege may “protect the secrecy of the underlying facts” in a way that the
    deliberative process privilege does not, and that, in any event, Army has not adequately justified
    its deliberative process withholdings. Pls.’ Reply 14–15 (quoting Mead Data Cent., 
    Inc., 566 F.2d at 254
    n.28); see also Pls.’ Mem. 37 (challenging failure to explain why both privileges
    “apply, which privilege applies to which redactions, or where they overlap”).
    Plaintiffs have the better argument. Although Defendants are correct as a matter of
    law—an agency can simultaneously invoke both privileges, and in some cases, the Court need
    only make a determination as to one—their conclusion is incorrect. Because neither Army’s
    declarations nor its Vaughn Index adequately indicate which privilege applies to which portions
    of the document, it has not in fact “sufficiently demonstrated” that its withholdings are proper
    pursuant solely to the deliberative process privilege. As the following discussion explains, the
    problem stems from the language that Army invokes and the manner in which it claims both
    privileges without any particularity as to which privilege applies to which portions of the
    document. This issue arises in several ways, which the Court will summarize before assessing
    why this approach is problematic, in context.
    First, despite explicitly claiming both privileges, many of Army’s justifications do appear
    to rely primarily on the deliberative process privilege—but without expressly stating that all
    redactions were applied pursuant to this privilege. In these instances, Army contends that the
    43
    redaction is justified because it “contains the opinions, recommendations, and suggestions of the
    authors regarding the proposed policies and reflect[s] the give-and-take of the consultative
    process.” Revised Updated Army Vaughn Index 2 (discussing Army 21); see also, e.g.,

    id. at 4
    4 (discussing redactions in Army 44 of
    “portions of email chain that reflected intra-agency deliberations regarding [] comments and
    recommendations” on a proposed draft). There are numerous other, similar examples in the
    Vaughn Index. At times, the entry for a record also states that the document is “predecisional,”
    see 
    id. at 2
    (characterizing Army 21 as a “predecisonal draft memorandum”); more often, Army
    implies the document’s predecisonal status, see, e.g., 
    id. at 7
    (referring to recommendations on a
    draft DODI and then referencing the final version of the DODI for Army 41); 
    id. at 3
    3–34
    (similar discussion of Army 86 and Army 88, respectively). One logical read of this language,
    which invokes the words associated with deliberative process privilege, is that Army claims only
    this privilege to justify all of these redactions. But because Army’s submissions simultaneously
    invoke attorney-client privilege, without specifying the portions of the document covered by
    either privilege or stating that all the redacted material is protected by the deliberative process
    privilege and the attorney-client privilege (e.g., that application of the privileges is coterminous),
    the Court cannot be certain.
    Moreover, although Defendants imply that the deliberative process privilege standing
    alone supports the withholdings in all of these documents, see Defs.’ Mem. P. & A. Opp’n 26
    44
    n.5, other entries in the Vaughn Index create doubt as to whether this privilege alone covers all
    the withholdings. For some of the documents, the justificatory language itself mixes the
    deliberative process and attorney-client legal standards in a way that creates ambiguity around
    Army’s rationale. Take Army 43, for which Army “redacted portions of [an] email exchange
    reflecting legal advice and recommendations.” Revised Updated Army Vaughn Index 8. At no
    point does Army establish which portions were redacted because of their status as opinions and
    recommendations (deliberative process privilege), or whether the same or different portions were
    redacted because of their status as legal advice or recommendations (attorney-client privilege).
    Or consider, as another representative example, Army 45, a set of emails in which attorneys from
    Army and “other military branches” provided “legal advice” to the Assistant Secretary of
    Defense (Health Affairs). 
    Id. at 9.
    For this document, Army “redacted portions of draft
    predecisional inter/intra agency communications between the client and agency counsel
    commenting on the proposed response” to a report by the Council on Ethical and Judicial Affairs
    on the grounds that the redacted portions “contain the opinions, recommendations, and
    suggestions of the authors regarding the proposed policies and reflect the give-and-take of the
    consultative process.”

    see also

    consist of “communications between agency counsel and client”);

    “legal and other comments,” or “legal recommendations” ); 
    id. at 4
    2 (similar language regarding
    redaction in Army 98 of “legal advice” on draft document). For some of these documents,
    moreover, Army has withheld in full an attached document, without explicitly specifying which
    privilege applies to it, and on what basis. See, e.g., 
    id. at 6
    (Army 40); 
    id. at 14
    (Army 52); 
    id. at 2
    1 (Army 69); 
    id. at 22
    (Army 70).
    Furthermore, for still other documents, the language of the Vaughn Index suggests even
    more strongly that Army—notwithstanding Defendants’ argument that solely the deliberative
    process privilege suffices to justify all redactions, see Defs.’ Mem. P. & A. Opp’n 26 n.5—relied
    in part on deliberative process and in part on attorney-client privilege. For an illustrative
    example, consider Army 107, which Army describes as a “[d]eliberative and advisory document
    prepared by legal counsel for the client prior to an agency decision” and as a “legal opinion”
    before explaining that it “redacted portions of [a] memorandum that consist of recommendations
    and other comments on the draft FM [2-22.3].” Revised Updated Army Vaughn Index 44
    (emphasis added); see also 
    id. at 17
    (stating that, for Army 17, Army “redacted portions of email
    communications between agency counsel and client” and also “redacted discussion, analysis, and
    proposed recommendations on [a] draft version” of a Detainee Ethics Memo); 
    id. at 3
    3 (similar
    language for Army 86 redactions). The trouble is that this mixture of deliberative process and
    attorney-client privilege language makes it confusing, if not impossible, to discern which
    privilege has been applied with respect to which withholdings.
    46
    As Plaintiffs rightly argue, this uncertainty about which privilege applies to a particular
    withholding has real stakes. The two privileges often overlap, yet they are not identical:
    attorney-client privilege covers the underlying factual material associated with an attorney’s
    provision of legal advice, whereas the “deliberative process privilege directly protects advice and
    opinions and does not permit the nondisclosure of underlying facts unless they would indirectly
    reveal the advice, opinions, and evaluations circulated within the agency as part of its decision-
    making process.” Mead Data Cent., 
    Inc., 566 F.2d at 254
    . Accordingly, without more specific
    detail as to which parts of which documents are withheld under which privilege, Army has not
    carried its burden to justify application of either privilege. See Pronin, 
    2019 WL 1003598
    , at *3
    (establishing that an agency seeking to invoke an exemption must “describe the requested
    documents and ‘the justifications for nondisclosure with reasonably specific detail.’” (quoting
    
    Larson, 565 F.3d at 862
    )). Even if the invocation of deliberative process privilege alone justifies
    at least some of Army’s redactions—which the Court does not decide at this juncture—it is not
    clear that all of the redactions are proper under this privilege. Thus, the Court directs Army to
    submit supplemental material to clarify which privilege it is claiming for each portion of these
    forty challenged documents, at which point it will determine whether Army’s justification for
    applying either one or both of these privileges is adequate. 26
    26
    This path is also most appropriate because the filings do not provide the information
    that is necessary to find that attorney-client privilege applies; notably, many of the Vaughn Index
    entries mention the involvement of attorneys, but fail either to establish the confidentiality of the
    communication or to establish with specificity that “obtaining or providing legal advice [was] a
    primary purpose of the communication, meaning one of the significant purposes of the
    communication.” In re Kellogg Brown & Root, 
    Inc., 756 F.3d at 760
    . Thus, the Court orders
    Army to, in any such supplementation: (1) clarify whether its invocation of deliberative process
    privilege and attorney-client privilege are coterminous in a given document; (2) explain, to the
    extent that attorney-client privilege alone shields any portion of the document, how that
    communication originally involved confidential information provided by the client, what specific
    47
    5. Segregability
    As previously discussed with regard to Defendants’ renewed motion for partial summary
    judgment, before addressing the exemptions claimed by the other Defendant agencies, the Court
    must assess one final matter concerning Defendant Army’s claimed exemptions: segregability. 27
    See 
    Sussman, 494 F.3d at 1117
    (discussing district court’s duty to consider segregability).
    Again, FOIA requires an agency invoking an exemption to disclose any reasonably segregable,
    non-exempt information. See Prop. of the People, 
    Inc., 330 F. Supp. 3d at 380
    (quoting
    Competitive Enter. 
    Inst., 232 F. Supp. 3d at 181
    ); see also 5 U.S.C. § 552(b). “To meet its
    burden on segregability, a government agency usually must submit a sufficiently detailed
    Vaughn Index for each document and an affidavit or declaration stating that it has released all
    segregable material.” Bloche 
    II, 370 F. Supp. 3d at 55
    (citing 
    Johnson, 310 F.3d at 776
    ).
    The parties in this case disagree as to whether Army has met this burden. In addition to
    generally challenging Army’s “over-withholding of information,” Pls.’ Reply 22, Plaintiffs argue
    that Army has failed to segregate and disclose non-exempt material for its deliberative process
    privilege claims and “has provided no explanation for why segregable information has not been
    legal advice was sought, and how the confidentiality of the material has been preserved; and (3)
    establish, to the extent that deliberative process privilege alone shields any portion of the
    document, what specific policy decision was at issue and how that deliberative process was
    predecisional to a final agency determination (including a choice not to act).
    27
    This Court will address segregability only with respect to the documents for which
    Army has provided adequate justification, as detailed above. Thus, the Court reserves discussion
    of the segregability of the following documents, for which Army’s Vaughn Index and
    declarations provide insufficient explanations: Army 21, Army 24, Army 25, Army 26, Army 34,
    Army 40, Army 41, Army 42, Army 43, Army 44, Army 45, Army 47, Army 48, Army 49,
    Army 50, Army 51, Army 52, Army 55, Army 56, Army 63, Army 64, Army 65, Army 66,
    Army 69, Army 70, Army 73, Army 74, Army 75, Army 76, Army 77, Army 78, Army 79,
    Army 86, Army 88, Army 89, Army 90, Army 91, Army 92, Army 93, Army 94, Army 98,
    Army 99, Army 107, Army 109, Army 111, Army 112, and Army 113.
    48
    released.” Pls.’ Mem. 27; see also 
    id. at 3
    8 (“Army has provided no explanation for why the
    redacted documents [to which it applied both the deliberative process and attorney-client
    privilege] do not contain segregable information.”). In support of this argument, Plaintiffs point
    to documents such as Army 46, a policy memorandum, and assert that such a document “must
    include background and factual information that is not deliberative in nature.” 
    Id. at 28.
    Along
    similar lines, Plaintiffs contend that Army 72, which includes a PowerPoint presentation on a
    proposed draft of FM 2-22.3 prepared for a “Familiarize Brief,” is “extremely likely” to “contain
    factual information and information on current policies in order to contextualize the proposed
    changes.” 
    Id. In response
    to Plaintiffs’ objections, Army updated its Vaughn Index entries, with
    “[p]articular attention . . . paid to the ten documents which were previously withheld in full.”
    Second Swords Decl. ¶ 5. Major Swords states that he “re-reviewed” these ten documents, nine
    of which relate to FM 2-22.3, and determined that one (Army 61) could be released in full and
    that “there was no reasonably segregable, non-exempt information that could be released in the
    remaining nine documents” based on his “line-by-line review.” Second Swords Decl. ¶ 10.
    But there are two fundamental problems with Army’s reliance on these submissions to
    establish that it has satisfied its segregability burden. First and foremost, this declaration
    addresses the nine wholly withheld documents with specificity, yet it never discusses Army’s
    review of the other documents to which it applied FOIA exemptions. Nor does Army’s first
    declaration include any statement that Army has released all segregable information. To be sure,
    by detailing the manner in which Army applied the deliberative process privilege, see Swords
    Decl. ¶ 7, Army invites the Court to infer that this is the case. But as in its March 2019
    memorandum opinion, “the Court declines this invitation; courts typically require sworn
    declarations or affidavits to avoid such conjecture.” Bloche 
    II, 370 F. Supp. 3d at 56
    . Thus,
    49
    Army has not established that there is no further, reasonably segregable information in its
    partially withheld documents.
    Second, there is a flaw in the justification for the fully withheld documents: it is not
    obvious which “ten documents” are referenced. On the Court’s count, the Vaughn Index on
    which Army presently relies to justify its withholdings lists twelve documents that remain
    withheld in full: Army 15, Army 16, Army 20, Army 22, Army 25, Army 26, Army 62, Army
    63, Army 64, Army 111, Army 112, Army 113. See Revised Updated Vaughn Index. Thus, the
    Court cannot pinpoint which documents are referenced in Army’s second declaration, which
    makes it impossible to identify with certainty which documents Major Swords re-reviewed in his
    segregability analysis. Army must therefore, for all documents, re-review its withholdings,
    produce any remaining, non-exempt segregable material that remains withheld, and submit a
    sworn statement to confirm that all segregable material has been released for all partially and
    wholly withheld documents. Until such time, Army has not satisfied what FOIA requires to
    withhold information in any of the sixty-nine challenged documents.
    As the Court previously mentioned, in addition to challenging these documents withheld
    in part or in full by Defendant Army, Plaintiffs contest the exemptions applied to nine documents
    by four other Defendant agencies: SOCOM 8, DIA 9-12, CENTCOM 1-9, CENTCOM 23-25,
    CENTCOM 36-49, JTF-GTMO 4-16, JTF GTMO 52-66, JTF-GTMO 78-90, and JTF-GTMO
    94-95. Beginning with Defendant SOCOM, the Court will next discuss these documents.
    B. SOCOM
    Plaintiffs challenge the withholding of information in SOCOM 8 pursuant to the
    deliberative process privilege, which, as previously discussed, requires Defendants to show that
    the withheld information is both predecisional and deliberative. See Prop. of the People, 
    330 F. 50
    Supp. 3d at 382. SOCOM 8 is a single page in a “38-page slide presentation from December
    2005 by the Deputy Director of SOCOM’s Psychological Applications Directorate concerning
    then-current applications of operational psychology.” Defs.’ Mot. Partial Summ. J. Ex. H,
    Declaration of Mark H. Herrington (“Herrington Decl.”) ¶ 6, ECF No. 96-9; see also Defs.’
    Mem. P. & A. Opp’n 22 (citing Herrington Decl. ¶ 6). The redacted page in the slide
    presentation discusses “repatriation lessons learned” and involves the author’s analysis of “how
    best to meet the psychological needs of U.S. prisoners of war when they are rescued and returned
    home.” Herrington Decl. ¶ 6. The specific information that SOCOM has withheld consists of
    “comments provided in 2003 by a soldier who was a prisoner of war during Operation Iraqi
    Freedom,” which SOCOM states consists of this soldier’s “opinions, advice, and
    recommendations.” 
    Id. Plaintiffs contest
    these withholdings as neither predecisional nor
    deliberative. First, Plaintiffs argue that the comments are not predecisional to “the document’s
    context[:]” “current agency application.” Pls.’ Mem. 30. Plaintiffs also maintain that the
    comments, which were made two years before the slide presentation was created, are “no longer
    predecisional” “[t]o the extent that the agency ha[s] chosen to adopt them, or decisionmakers
    incorporated them into the final policy.” 
    Id. Second, Plaintiffs
    contend that SOCOM “has failed
    to specifically describe the role this information played” in its decisionmaking. 
    Id. at 31.
    Defendants counter that this argument misconstrues the relevant decisionmaking context:
    “SOCOM’s ‘consideration of improvements in the repatriation process’ for U.S. service
    members who were prisoners of war.” Defs.’ Mem. P. & A. Opp’n 23 (quoting Herrington Decl.
    ¶ 6). As such, Defendants assert that the soldier’s opinions and recommendations are both
    predecisional and deliberative, and thus properly privileged. 
    Id. 51 Without
    more specificity about the decisionmaking timeline and context, however,
    SOCOM has failed to carry its burden concerning application of the privilege. To qualify as
    deliberative and hence subject to the privilege requires, “in essence, that the communication is
    intended to facilitate or assist development of the agency’s final position on the relevant
    issue.” Nat’l Sec. 
    Archive, 752 F.3d at 463
    (citing Russell v. Dep’t of the Air Force, 
    682 F.2d 1045
    , 1048 (D.C. Cir. 1982)). Here, SOCOM has not explained how, exactly, the comments
    from 2003 contributed to the agency’s deliberative process concerning a final position on the
    relevant issue. SOCOM does state a general policy justification for the withholding, explaining
    that “[d]ebriefings of former U.S. prisoners of war are kept in confidence to ensure full
    disclosure and to avoid service personnel withholding information for fear of embarrassment.”
    Herrington Decl. ¶ 6. But this overarching policy rationale does not connect the 2003 comments
    up to a deliberative process culminating in a final agency position on how to improve the
    repatriation process for former prisoners of war.
    This lack of detail is especially problematic, moreover, because “application of the
    deliberative process privilege is context-specific.” 
    Hardy, 243 F. Supp. 3d at 168
    (quoting
    Edmonds Inst. v. U.S. Dep’t of Interior, 
    460 F. Supp. 2d 63
    , 70 (D.D.C. 2006)); see also Coastal
    
    States, 617 F.2d at 867
    (stating that the applicability of the privilege depends on the role that
    information “plays in the administrative process”). On the submissions provided, the Court lacks
    the information it needs to evaluate SOCOM’s application of the privilege, in context. The key
    problem, put simply, is that SOCOM does not say anything about how or why the comments
    were gathered in 2003. Were they provided as part of an earlier policymaking initiative or
    decision point, or were they collected as part of the same deliberative process to which the 2005
    presentation contributed? Or, in the alternative, were they gathered as part of the individual’s
    52
    debriefing, and then subsequently applied to inform an agency policy evaluation? Without
    knowing more, the Court cannot ascertain what role, if any, the redacted communication played
    in facilitating or assisting development of the agency’s final position on the matter. And as such,
    it cannot ascertain whether the redacted comments are deliberative in the manner that the
    privilege requires. Nor does SOCOM clarify the role of the 2005 presentation in which the
    redacted comments appear vis-à-vis the agency’s deliberative process concerning the same issue.
    This lack of specificity makes it all the more difficult to determine the role of the comments with
    respect to the “frank exchange of ideas and opinions,” Nat’l Sec. 
    Archives, 752 F.3d at 462
    (quoting Dudman 
    Comm’ns, 815 F.2d at 1567
    ), required to formulate the agency’s final position.
    It is possible that the material is in fact privileged. But on the material provided, SOCOM’s
    justification is insufficient to allow the Court to draw any firm conclusions. Thus, to the extent
    that SOCOM continues to rely on the deliberative process privilege to withhold the material, the
    Court directs SOCOM to submit a supplementary declaration or affidavit that provides this
    missing information. 28
    C. DIA
    A single document is also at issue with respect to Defendant DIA, which has withheld in
    full a four-page trip report, DIA 9-12. Defs.’ Mot. Partial Summ. J. Ex. C, Declaration of Alesia
    Y. Williams in Support of Defendants’ Motion for Summary Judgment (“Second Williams
    28
    Until such time, the Court reserves the question of whether the material has been
    properly segregated. SOCOM’s supplementation must clarify: (1) the agency decision or
    deliberative process for which the comments were gathered in 2003, and how that context relates
    to the context in which the 2005 presentation was delivered, and (2) whether any portion of the
    2003 advice and recommendations was implemented as SOCOM’s final policy between the time
    that the comments were provided and delivery of the 2005 presentation.

    Declaration”) ¶¶ 8–20, ECF No. 96-4. 29 This document is a “written summary of a trip taken” in
    late 2002 and early 2003 to “assess DoD interrogation at Guantanamo Bay.” 
    Id. ¶ 8.
    DIA
    justifies the withholding by invoking three FOIA exemptions: it shielded (1) “certain information
    in DIA 9-12” under FOIA Exemption 1 because it “relates to intelligence sources and methods,”
    
    id. ¶ 12;
    (2) “certain information in DIA 9-12” under FOIA Exemption 3 because it “specifically
    identif[ies] the names of DIA personnel, specific DIA office symbols, and specific DIA
    activities,” release of which would contravene 10 U.S.C. § 424; and (3) “certain information
    from DIA 9-12” under FOIA Exemption 5 because it “constitutes an intra-government agency
    communication that includes recommendations relating to interrogation TTPs” based on the
    author’s “experiences and observations,” 
    id. ¶ 20.
    Plaintiffs do not contest DIA’s Exemption 3
    withholdings “to the extent they are not being used to withhold the document in full.” Pls.’
    Reply 24 (citing Pls.’ Mem. 21). Plaintiffs do, however, challenge DIA’s withholding in full on
    the grounds that “it is impossible for Plaintiffs to know how much has been withheld under each
    exemption.” Pls.’ Mem. 21. Thus, Plaintiffs argue that,” “[e]ven if all three of these Exemptions
    adequately apply to specific sections of the document,” it is not possible to draw this conclusion
    without knowing “which Exemptions apply to which sections.” Pls.’ Reply 24.
    In this case, for reasons similar to those outlined previously with respect to Defendant
    Army’s concurrent deliberative process and attorney-client privilege withholdings, the Court
    agrees with Plaintiffs. Neither the declaration provided nor DIA’s Vaughn Index, see Pls.’ Mem.
    Ex. C, Vaughn Index to the Declaration of Alesia Y. Williams, ECF No. 97-5, indicates which
    portions of the document were redacted pursuant to which privilege. The Vaughn Index,
    29
    The initial Williams Declaration discusses the documents contested in Defendants’
    renewed motion for partial summary judgment, see ECF No. 110, addressed previously in this
    opinion. The instant declaration was provided in 2018 and concerns the documents at issue in
    the parties’ pending cross-motions for summary judgment. See ECF Nos. 96, 97.
    54
    confusingly, makes no mention of Exemption 5 in discussing DIA 9-12. See 
    id. DIA instead
    offers a blanket reference to “certain information” in justifying each exemption. See Second
    Williams Decl. ¶¶ 8, 12, 20. Nor do DIA’s submissions at any point state whether any single
    privilege would shield the document in full. It is easy to intuit which portions were redacted
    pursuant to Exemption 3, yet this is not the case for Exemptions 1 and 5, which—on the
    information provided—may have been applied to distinct parts of the document. Until DIA
    clarifies whether it applied Exemption 1 and Exemption 5 to the same or different portions of
    DIA 9-12, it is premature for the Court to draw conclusions as to whether the document is
    properly withheld. Thus, the Court directs DIA to submit a supplementary affidavit or
    declaration that states which portions of DIA 9-12 were withheld pursuant to which FOIA
    exemption, whereupon it will determine the adequacy of DIA’s justifications as well as whether
    it has properly segregated all non-exempt material.
    D. CENTCOM
    Plaintiffs contest Defendant CENTCOM’s redaction of portions of three documents
    pursuant to Exemption 1: CENTCOM 1-9, CENTCOM 23-35, and CENTCOM 36-49. Because
    the Court has not yet discussed what an agency must establish to apply Exemption 1, it will set
    forth the applicable legal standard before assessing whether CENTCOM may partially withhold
    these documents. For the following reasons, CENTCOM has carried its burden here and may
    apply Exemption 1 to shield portions of these three documents.
    1. Exemption 1
    FOIA Exemption 1 “protects material that is (1) “specifically authorized under criteria
    established by an Executive order to be kept secret in the interests of national defense or foreign
    policy” and (2) “in fact properly classified pursuant to such [an] Executive order.” 5 U.S.C. §

    552(b)(1); see also 
    Larson, 565 F.3d at 861
    (quoting 5 U.S.C. § 552(b)(1)). For an agency to
    withhold material under Exemption 1, the information at issue “must be classified in accordance
    with the procedural criteria of the governing Executive Order as well as its substantive terms.”
    Lesar v. U.S. Dep’t of Justice, 
    636 F.2d 472
    , 483 (D.C. Cir. 1980). The basis for classification of
    national security information that is relevant here is located in Executive Order 13,526 (“EO
    13,526”). See Defs.’ Mot. Partial Summ. J. Ex. J., Declaration of Major General Michael Erik
    Kurilla (“Kurilla Decl.”) ¶ 8, ECF No. 96-11.
    Under EO 13,526, four conditions are required to establish that information has been
    properly classified: (1) “an original classification authority is classifying the information;” (2)
    the United States Government owns or controls the information, or the information was produced
    by or for the Government; (3) “the information falls within one or more of the categories of
    information listed in section 1.4” of EO 13,526; and (4) “the original classification authority
    determines that the unauthorized disclosure of the information reasonably could be expected to
    result in damage to the national security” and “is able to identify or describe the damage.” Exec.
    Order 13,526, 75 Fed. Reg. 707, 707 (Dec. 29, 2009); see also Elec. Privacy Info. Ctr. v. U.S.
    Dep’t of Justice, 
    296 F. Supp. 3d 109
    , 124 (D.D.C. 2017) (discussing EO 13,526). Section 1.4 of
    EO 13,526 identifies eight categories of information that “could reasonably be expected to cause
    identifiable or describable damage to the national security[,]” including, as relevant here,
    information pertaining to “military plans, weapons systems, or operations” or “intelligence
    activities (including covert action), intelligence sources or methods, or cryptology.” Exec. Order
    13,526, 75 Fed. Reg. at 709. “Thus, if information that is responsive to a FOIA request fits into
    any of the eight categories, and if an original classifying authority has designated the information
    classified based on that authority’s determination that the unauthorized disclosure of the
    56
    information reasonably could be expected to result in damage to the national security, the
    information has properly been deemed ‘classified’ and the government can invoke Exemption 1
    to withhold the information from disclosure under the FOIA.” Elec. Privacy Info. Ctr., 296 F.
    Supp. 3d at 124–25 (citing 
    Larson, 565 F.3d at 864
    ).
    As with all FOIA exemptions, an agency that withholds information pursuant to
    Exemption 1 bears the burden of justifying its decision. 
    King, 830 F.2d at 217
    nn.57–58 (citing
    5 U.S.C. § 552(a)(4)(B)). The agency must, as with all FOIA exemptions, put forth a
    justification for invoking the exemption that “appears logical or plausible.” Dillon, 
    2019 WL 249580
    , at *8 (quoting 
    Wolf, 473 F.3d at 374
    –75)). That said, the national security context is
    unique, and courts in this Circuit have “consistently deferred to executive affidavits predicting
    harm to the national security[] and have found it unwise to undertake searching judicial
    review.” Nat’l Sec. Counselors v. Cent. Intelligence Agency., 
    960 F. Supp. 2d 101
    , 164–65
    (D.D.C. 2013) (quoting Ctr. for Nat’l Sec. Studies v. U.S. Dep’t of Justice, 
    331 F.3d 918
    , 927
    (D.C. Cir. 2003)); see also James Madison Project v. Cent. Intelligence Agency, 
    605 F. Supp. 2d 99
    , 109 (D.D.C. 2009) (citing Schlesinger v. Cent. Intelligence Agency, 
    591 F. Supp. 60
    , 67
    (D.D.C. 1984), then citing Halperin v. Cent. Intelligence Agency, 
    629 F.2d 144
    , 148 (D.C. Cir.
    1980)). Courts are thus to “accord substantial weight to an agency’s affidavit concerning the
    details of the classified status of the disputed record,” while taking into account the reality “that
    any affidavit or other agency statement of threatened harm to national security will always be
    speculative to some extent, in the sense that it describes a potential future harm.” Am. Civil
    Liberties Union v. Dep’t of Def., 
    628 F.3d 612
    , 619 (D.C. Cir. 2011) (quoting 
    Wolf, 473 F.3d at 374
    ).
    57
    2. Defendant’s Application of Exemption 1
    In this case, CENTCOM both affirms that the material is properly classified and states
    that it is properly withheld under Section 1.4(a) and 1.4(c) of EO 13,526. See Kurilla Decl. ¶¶ 8–
    10. This information is classified at the SECRET level, “including records labelled
    SECRET//NOFORN (which prohibits even foreign coalition partners from viewing the
    records).” 
    Id. ¶ 8.
    CENTCOM states that material redacted on one page of CENTCOM 1-9, one
    page of CENTCOM 23-35, and four pages of CENTCOM 26-39 concerns “document titles and
    procedures related to interrogation.” 
    Id. ¶ 11
    (discussing redactions at “bates numbered pages[]
    3, 25, 40, and 45-47”). It submits that “[d]ivulging these procedures would provide future
    potential detainees with invaluable insight into interrogation operations[,] enabling them to
    overcome techniques to extract vital intelligence.” Id.; see also Pls.’ Mem. Ex. K, CENTCOM
    Vaughn Index 2–3, ECF No. 97-13. 30
    The CENTCOM Vaughn Index adds further detail regarding each document. For
    CENTCOM 1-9, “[t]he redacted information would reveal tactics, techniques, and procedures
    (TTPs) for collecting and assessing intelligence information[] and reviewing intelligence and
    operational plans.” CENTCOM Vaughn Index 2. For CENTCOM 23-25, “[t]he redacted
    information would reveal interrogation methods and approaches by personnel involved in
    assessing detainees and intelligence processes.” 
    Id. at 3.
    And for CENTCOM 26-49, the
    redacted information would reveal not only “interrogation methods and approaches,” but also
    “operational plans when other countries are involved.” 
    Id. Thus, CENTCOM
    asserts that it has
    30
    Because this document is not paginated, the Court refers to it here and throughout this
    opinion with the ECF page numbers.
    58
    withheld this information as properly shielded by Section 1.4(a). 31 CENTCOM also states that it
    withheld material located within CENTCOM 1-9 pursuant to Section 1.4(c) because it “relates to
    intelligence-gathering efforts, methods, and results,” the disclosure of which would also risk
    giving “future potential detainees” “invaluable insight” that would “enable[e] them to overcome
    techniques to extract vital intelligence.” Kurilla Decl. ¶ 12 (discussing challenged withholding
    “located on bates numbered page[] 3”). The information withheld on this basis is the same
    information withheld under Section 1.4(a). See Defs.’ Mem. P. & A. Supporting Renewed Mot.
    8.
    Plaintiffs do not argue that the challenged information is improperly classified, but rather
    contest the sufficiency of CENTCOM’s justifications. Plaintiffs assert that “CENTCOM does
    not make clear how each” of the “particular documents” at issue “would in fact harm national
    security if released,” Pls.’ Mem. 18, in the manner required to sustain its Exemption 1 claim. In
    particular, Plaintiffs contest CENTCOM’s repeated reliance on a “blanket statement” that these
    documents could provide “‘invaluable insight into interrogation operations,’ without explaining
    how or why.” 
    Id. at 18–19.
    Without more, Plaintiffs press the Court to deem “CENTCOM’s
    broad justification . . . too conclusory to satisfy the Exemption 1 plausible and logical standard”
    and to conduct in camera review. Pls.’ Reply 8.
    The Court agrees that CENTCOM’s justifications are terse. Contrary to Plaintiffs’
    contentions, however, its submissions are sufficiently detailed to establish that the withheld
    portions logically and plausibly fall within Exemption 1’s protections for classified material.
    The titles of each of the documents contextualize CENTCOM’s justifications: CENTCOM 1-9 is
    “an appendix to the Behavioral Science Consultation Team Standard Operation Procedures,” and
    31
    Although the Vaughn Index also discusses Section 1.4(c) with respect to CENTCOM
    36-49, because the declaration does not, the Court focuses only on 1.4(a) here.
    59
    both CENTCOM 23-25 and CENTCOM 36-49 are “Multi-National Force-Iraq Interrogation
    Policy” documents. Kurilla Decl. ¶ 6. Based on these titles and the SECRET level of
    classification for “document titles and procedures related to interrogation” contained in these
    documents, it strikes the Court as logical and plausible that the documents contain “details of
    practices associated with interrogation,” the disclosure of which would risk undermining the
    future viability of techniques relied upon “to extract vital intelligence.” 
    Id. at 11.
    As Defendants
    put this point, drawing from the Kurilla Declaration: “it is both logical and plausible that
    disclosure of information pertaining to the military’s interrogation methods reasonably could be
    expected to harm the national security by providing ‘future potential detainees with invaluable
    insight into interrogation operations,’ which would ‘enable[e] them to overcome [the military’s
    interrogation] techniques[,]’ thereby diminishing the military’s ability to ‘extract vital
    intelligence’ from adversaries.” Defs.’ Mem. P. & A. Opp’n 9 (quoting Kurilla Decl. ¶ 12). The
    Court is hard-pressed to say how CENTCOM could explain “how or why” release of the
    documents would harm national security interests, Pls.’ Mem. 18–19, with any greater
    specificity, without risking disclosure of the classified techniques themselves. Nor do Plaintiffs
    suggest what, exactly, is missing from the CENTCOM submission, beyond resting on the
    allegation that it is too conclusory and repetitive.
    CENTCOM has thus met its “light” burden, Am. Civil Liberties 
    Union, 628 F.3d at 624
    ,
    to establish a risk of a particular category of harm articulated in section 1.4 of EO 13,526 with
    respect to the release of properly classified information, such that it may properly invoke
    Exemption 1. CENTCOM also submits, via sworn affidavit, that its FOIA Office conducted a
    “line-by-line” review of each record and, “with respect to the records that were released in part,
    all information not exempted from disclosure pursuant” to an exemption “was correctly
    60
    segregated and non-exempt portions were release[d].” Kurilla Decl. ¶ 17. Thus, CENTCOM has
    satisfied what FOIA requires and may partially withhold CENTCOM 1-9, CENTCOM 23-35,
    and CENTCOM 36-49 pursuant to Exemption 1.
    E. JTF-GTMO
    The final matter before the Court in the parties’ cross-motions for partial summary
    judgment is Defendant JTF-GTMO’s application of FOIA exemptions. Plaintiffs contest the
    partial withholding of JTF-GTMO 4-16, JTF-GTMO 52-66, JTF-GTMO 78-90, 32 and JTF-
    GTMO 94-95 pursuant to Exemption 7(E) and Exemption 1. See Updated History of Disputed
    Docs. 6. Because JTF-GTMO claims Exemption 7(E) as the basis for withholding most of the
    redacted information in JTF-GMTO 4-16 and JTF-GTMO 52-66, see Defs.’ Mot. Partial Summ.
    J. Ex. I-1, ECF No. 96-10 (redacted versions of documents), the Court begins there. 33
    Before proceeding with this analysis, however, the Court will attempt to clarify what,
    exactly, is contested at this juncture, and how it relates to the parties’ submissions. JTF-GTMO
    has provided redacted versions of the documents, and Defendants explain how some—but
    critically, not all—of the documents that Plaintiffs challenge are included in the material that
    JTF-GTMO attached to its declaration as Exhibit 1. Defendants state that “the pages released to
    Plaintiffs as GTMO 4-16 and GTMO 78-90 appear as GTMO 001-0013 in Exhibit 1” and “the
    32
    Because both parties acknowledge that JTF-GTMO 78-90 is a duplicate of JTF-GTMO
    4-16, Defs.’ Mot. Partial Summ. J. 15 (citing Ring Decl. ¶ 5); Pls.’ Mem. 15, the Court does not
    separately address it.
    33
    In contrast to the exemptions applied by the other Defendants, because JTF-GTMO has
    provided three of the redacted documents as an exhibit attached to its declaration, it is evident
    where these exemptions are coterminous and where they apply to different portions of a
    document. See Defs.’ Mot. Partial Summ. J. Ex. I-1, ECF No. 96-10. On the Court’s read of
    these documents, JTF-GTMO has applied Exemption 7(E) to all redacted portions of JTF-
    GTMO 4-16 and JTF-GTMO 52-66 for which it also applied Exemption 1. For the reasons
    detailed below, it cannot assess whether this is also the case for the other redactions at issue.
    61
    pages released to Plaintiffs as GTMO 52-66 appear as GTMO 0023-0037.” Defs’ Mem. 15 n.5.
    This explanation leaves the Court with two puzzles. First, although Plaintiffs indicate that they
    challenge the partial withholding of JTF-GTMO 94-95, there is no mention of it in either of the
    parties’ filings apart from the entry in Plaintiffs’ history of disputed documents—nor does
    Defendants’ exhibit appear to include it. Based on JTF-GTMO’s declaration and Vaughn Index,
    it is possible that this document is a duplicate of JTF-GTMO 52-66. See Ring Decl. ¶ 5
    (discussing the release of the document “redactions in 2008, at which time duplicates of the same
    document were released with bates-stamped pages 17-18 and 94-95”); JTF-GTMO Vaughn
    Index 5, ECF No. 97-10 34 (indicating that the document is a duplicate). But because the Vaughn
    Index entry is most similar to the one for JTF-GTMO 78-90, see JTG-GTMO Vaughn Index 5,
    the Court is not certain whether it is a duplicate of that document, which is itself a duplicate of
    JTF-GMTO 4-16. Without clarification concerning what other record this document duplicates
    and—if it is different from one of the other contested documents—what justification applies to
    the redactions within it, the Court cannot determine whether JTF-GTMO has carried its burden
    regarding JTF-GTMO 94-95. To the extent that JTF-GTMO continues to withhold information
    in either of these documents, it must submit further supplementation clarifying the basis for its
    withholdings in GTMO 94-95. 35
    Second, a similar ambiguity plagues another aspect of JTF-GTMO’s submissions.
    Although the exhibit containing redacted documents contains a third document, located at Bates
    34
    Because this document is not paginated, the Court refers to it with the ECF page
    numbers.
    35
    Although Plaintiffs do not make any arguments concerning this withholding, because
    the agency bears the burden of showing that the privilege properly applies, see Dillon, 
    2019 WL 249580
    at *8 (citing Prop. of the 
    People, 330 F. Supp. 3d at 380
    ), and because Plaintiffs appear
    to challenge it, JTF-GTMO must offer a “relatively detailed justification” of its application of the
    privilege, Elec. Privacy Info. 
    Ctr., 192 F. Supp. 3d at 103
    (quoting Mead Data Cent., 
    Inc., 566 F.2d at 251
    ), before the Court can say whether JTF-GTMO has carried its burden.
    62
    numbered pages 0014 and 0015, see Defs.’ Mot. Partial Summ. J. Ex. I-1, ECF No. 96-10 at 23–
    24, 36 and the Ring Declaration discusses this document, neither party explains how these pages
    correspond to a contested document. The Ring Declaration itself states that it refers to
    documents “by the page numbers associated with their 2008 and 2018 releases, which are the
    page numbers utilized by Plaintiffs’ Consolidated Spreadsheet of Insufficient Document
    Productions from Defendant Agencies,” Ring Decl. ¶ 5, which was attached to the parties’ May
    18, 2018 Joint Status Report, see ECF No. 90-1. But this spreadsheet does not include any
    document that corresponds to these Bates numbers. Nor does Plaintiffs more recent submission
    of the documents it continues to challenge discuss these Bates numbers. See Updated History of
    Disputed Docs. Thus, because the Court cannot link up the justifications and exhibit provided to
    an identifiable document that remains contested, it cannot determine the propriety of JTF-
    GTMO’s redactions on these Bates numbered pages. It is to prevent exactly this sort of
    difficulty that government agencies often rely on Vaughn indices in the first instance. See
    
    Vaughn, 484 F.2d at 827
    (“The need for adequate specificity is closely related to assuring a
    proper justification by the governmental agency.”). To clear up this issue, the Court directs the
    parties to indicate whether the material located at Bates numbered pages 0014-0015 remains
    challenged and how the document is identified. If Plaintiffs do in fact contest this material, then
    JTF-GTMO must pinpoint its justification for the withholdings therein, whereupon the Court will
    assess whether these justifications are adequate.
    Turning back to JTF-GTMO 4-16 and JTF-GTMO 52-66, for the reasons set forth below,
    JTF-GTMO has not provided sufficient explanation for its invocation of Exemption 7(E).
    36
    Because these documents have been paginated multiple times, to avoid confusion, the
    Court refers here to the ECF page numbers as the authoritative source.
    63
    1. Exemption 7(E)
    As discussed previously with respect to Defendants’ renewed motion for partial summary
    judgment, ECF No. 110, an agency seeking to apply Exemption 7(E) must (1) demonstrate that
    the “records or information” were “compiled for law enforcement purposes,” 5 U.S.C. §
    552(b)(7)(E), and (2) “demonstrate logically how the release of the requested information might
    create a risk of circumvention of the law,” Mayer Brown 
    LLP, 562 F.3d at 1193
    –94. In
    assessing the risk of circumvention of the law, this Circuit has emphasized the “relatively low
    bar,” 
    Blackwell, 646 F.3d at 42
    , that the agency must clear: “the exemption looks not just for
    circumvention of the law, but for a risk of circumvention; not just for an actual or certain risk of
    circumvention, but for an expected risk; not just for an undeniably or universally expected risk,
    but for a reasonably expected risk; and not just for certitude of a reasonably expected risk, but for
    the chance of a reasonably expected risk.” Mayer Brown 
    LLP, 562 F.3d at 1193
    . That said, to
    meet even this low bar, the agency must “demonstrate logically how the release of the requested
    information might create a risk of circumvention of the law,” 
    id. at 11
    94, in a nonconclusory
    fashion that does more than “essentially just restate[] the applicable legal standard in different
    words,” see Bloche 
    II, 370 F. Supp. 3d at 58
    .
    2. Defendant’s Application of Exemption 7(E)
    Again, JTF-GTMO applied Exemption 7(E) to all of the redactions in JTF-GTMO 4-16
    and JTF-GTMO 52-66. Because JTF-GTMO’s Vaughn Index does not discuss the application of
    Exemption 7(E) to either document—only the application of Exemption 1 and other exemptions
    not at issue here—the Court relies on the justification provided in the Ring Declaration. JTF-
    GTMO 4-16 is a document entitled “Behavioral Science Consultation Team, Joint Intelligence
    Group, Joint Task Force – GTMO, Standard Operating Procedures,” Ring Decl. ¶ 5, that was
    64
    created to “establish Standard Operating Procedures (SOP) for the daily operation of the
    Behavioral Science Consultation Team (BCST)” at Guantanamo Bay, Cuba, Defs.’ Mot. Partial
    Summ. J. Ex. I-1. JTF-GTMO 52-66 is a “notes page printout,” Defs.’ Mot. Partial Summ. J. Ex.
    I-1 at 4, for “an undated slide presentation titled ‘Interrogator Training’” that “was prepared to
    explain the legal basis and justifications” for JTF-GTMO’s interrogations. Ring Decl. ¶ 5. For
    both of these documents, JTF-GTMO states that the exemption meets Exemption 7’s threshold
    requirement that the records were compiled for “the law enforcement purposes of pursuing a
    violation of federal law and a breach of national security.” 
    Id. ¶ 14.
    JTF-GTMO further offers
    that “the records contain information related to detainee observation protocols and detainee
    management strategies,” 
    id. ¶ 15,
    such that release of the withheld information could allow
    detainees to “better understand how the guard force operates and government strategies for
    ensuring the security of detention and interrogation operations, which could be used to evade
    those protocols,” 
    id. ¶ 16.
    Plaintiffs do not challenge the statement that the information was
    compiled for law enforcement purposes, but instead attack JTF-GTMO’s justification as
    insufficient to satisfy what Exemption 7(E) demands. See Pls.’ Mem. 40. Plaintiffs contend that
    JTF-GTMO has not set forth with adequate particularity “how potential evasion of protocols
    would lead to circumvention of the law.” 
    Id. Here, even
    taking into account Exemption 7(E)’s low bar, the Court agrees that JTF-
    GTMO’s justification is wanting. As this Court concluded in its March 2019 memorandum
    opinion with respect to similar language offered by Defendant Navy, see Bloche II, 
    370 F. Supp. 3d
    at 58, the conclusory language provided does little more than restate the applicable legal
    standard. Although JTF-GTMO does mention the “guard force” and “government strategies for
    ensuring the security of detention and interrogation operations,” it does not include any further
    65
    details, such as whether the information pertains to personnel, timing, reliability, or other matters
    entirely. And this lack of any further information means that the Court can only speculatively
    connect the dots to determine how release of the redaction could create the “chance of a
    reasonably expected risk” of circumvention of the law. Defendants’ arguments to the contrary
    are unavailing. For instance, Defendants invoke Rosenberg v. Dep’t of Defense, 
    342 F. Supp. 3d 62
    , 94 (D.D.C. 2018), as a recent case that “credit[ed] JTF-GTMO’s explanation that ‘detainees’
    improved understanding’ of security-related protocols ‘could reasonably be expected to ‘create a
    risk of circumvention.’” Defs.’ Mem. P. & A. Opp’n 29. But in Rosenberg, the redacted
    information involved a far more specific topic: “the inherently contentious and confrontational
    topic of enteral feeding of JTF-GTMO 
    detainees.” 342 F. Supp. 3d at 94
    (internal quotation
    mark and citation omitted). In this case, JTF-GTMO has not provided the Court with a
    comparably specific topic at issue in the redacted material. The Court can imagine the topic, to
    be sure, based on the surrounding text. But the justifications themselves fail to spell it out, and it
    is the duty of the agency—not the Court—to establish the requisite connection between a law
    enforcement “individual or incident” and possible security risk or violation of federal law.
    
    Blackwell, 646 F.3d at 40
    (quoting 
    Campbell, 164 F.3d at 32
    ).
    Accordingly, JTF-GTMO has not carried its burden to establish that it properly withheld
    information pursuant to Exemption 7(E) in JTF-GTMO 4-16 and JTF-GTMO 52-66. 37 Again, in
    such a situation, “the district court . . . has several options, including inspecting the
    37
    The Court recognizes that Exemption 1 was also applied to portions of the document,
    and may independently protect these limited redactions. But because this exception does not
    shield the remainder of the redacted portions, and because JTF-GTMO applied Exemption 7(E)
    to all portions of the document to which it also applied Exemption 1, the Court will address the
    application of Exemption 1 only if it—upon submission of further supplementary material—
    concludes that Exemption 7(E) does not properly shield the withheld portions of the challenged
    documents.

    documents in camera, requesting further affidavits, or allowing the plaintiff discovery.” Pub.
    Emps. for Envtl. Responsibility v. Envtl. Prot. Agency, 
    213 F. Supp. 3d 1
    , 16 (D.D.C. 2016)
    (citing Spirko v. U.S. Postal Serv., 
    147 F.3d 992
    , 997 (D.C. Cir. 1998)). Here, particularly since
    parts of the documents at issue remain classified, the Court finds supplementary justification to
    be the most appropriate path to resolution. The Court thus directs Defendant JTF-GTMO to
    provide updated justifications for its application of FOIA exemptions, either in the form of new
    declarations or a revised Vaughn index, see 
    Vaughn, 484 F.2d at 826
    –28. 38 After such a
    submission, Plaintiffs shall confirm that all four documents remain contested, and either or both
    parties may file renewed motions and/or cross-motions for summary judgment.
    V. CONCLUSION
    For the foregoing reasons, Defendants’ renewed motion for partial summary judgment,
    ECF No. 110, is GRANTED with respect to Defendant Navy, GRANTED with respect to
    Defendant OASD-HA Policy 659, OASD-HA Policy 758-59, OASD-HA Policy 761-62, and
    OASD-HA Policy 765-66 and DENIED with respect to OASD-HA Policy 27-35. Defendants’
    motion for partial summary judgment, ECF No. 96, is GRANTED with respect to all federal
    Defendants’ application of FOIA exemptions other than the application of exemptions in the

    In this supplementary filing, JTF-GTMO is to: (1) clarify its basis for withholding JTF-

    and whether any such document has been released in full or in part; (2) indicate what document
    on Plaintiffs’ Updated History of Disputed Documents, ECF No. 101-1, it refers to in its
    justification of the material located at Bates numbered pages 0014-0015; and (3) supplement its
    justifications for withholding information pursuant to Exemption 7(E) to address the issues
    identified above.
    39
    For the following forty-seven documents, summary judgment is denied because the
    explanation is inadequate, for the reasons specified in this opinion: Army 21, Army 24, Army 25,
    67
    52-66, JTF-GTMO 78-90 and JTF-GTMO 94-95. Plaintiffs’ cross-motion for partial summary
