    Before: SRINIVASAN, Chief Judge, MILLETT and WALKER,
    Circuit Judges.
    Opinion for the Court filed by Chief Judge SRINIVASAN.
    SRINIVASAN, Chief Judge: In 2003, while on deployment
    with the Army in Iraq, Jason Sissel suffered back and leg
    injuries in a motor vehicle accident. The Army’s medical
    evaluations determined that his condition rendered him unfit
    for duty. Depending on the extent of his disability, Sissel could
    either be “retired” from service, in which case he would receive
    retirement benefits, or “separated” from service, in which case
    he would receive severance pay but no retirement benefits. The
    Secretary of the Army gave Sissel a disability rating of 20%,
    below the 30% threshold necessary to qualify him for
    retirement from service.
    Sissel brought an action against the Army in district court,
    challenging the Secretary’s assignment of a 20% disability
    rating. According to Sissel, the Secretary should have given
    him a 30% rating, consistent with the rating he had received
    from the Department of Veterans Affairs in a separate
    3
    assessment conducted by the VA to determine his eligibility for
    veterans’ disability benefits.
    The district court granted summary judgment in favor of
    the Army. We conclude, however, that the Secretary’s
    approach when determining Sissel’s disability rating was
    inconsistent with the applicable statute and regulations. We
    thus vacate the grant of summary judgment to the Army and
    remand for further proceedings.
    I.
    A.
    If a military servicemember incurs a “physical
    disability . . . while entitled to basic pay,” the Secretary of the
    relevant military department determines if the disability
    renders the servicemember “unfit to perform the duties of the
    member’s office, grade, rank or rating.” 
    10 U.S.C. §§ 1201
    (a),
    1203(a). If the servicemember has been rendered unfit, the
    servicemember may be either “retired” or “separated” from
    service, depending on the degree of disability. 
    Id.
     §§ 1201(a),
    1203(a). A retired servicemember is eligible to receive
    retirement benefits, whereas a separated servicemember
    receives only severance pay with no retirement benefits. See
    id. §§ 1201(a), 1203(a).
    For a servicemember with fewer than 20 years of service,
    the member can qualify for retirement if the relevant Secretary
    finds that “the disability is at least 30 percent under the standard
    schedule of rating disabilities.” Id. § 1201(b)(3)(B). If the
    servicemember’s disability falls below that 30% threshold, “the
    member may be separated from the member’s armed force,
    with severance pay,” but not retirement benefits. Id. § 1203(a);
    see also White v. Mattis, No. 18-cv-02867, 
    2019 WL 6728448
    ,
    4
    at *1 (D.D.C. Dec. 11, 2019) (“Soldiers who are separated are
    entitled only to severance pay, while soldiers who are retired
    receive, inter alia, lifetime retired pay, healthcare, and
    commissary privileges.”).
    B.
    For Army personnel, the Secretary of the Army makes
    fitness and ratings determinations under a process known as the
    Physical Disability Evaluation System (DES). See Dep’t of the
    Army, Army Regul. 635-40, Disability Evaluation for
    Retention, Retirement or Separation (2017) (2017 Army Regul.
    635-40). The specific version of the DES used to evaluate
    Sissel’s disability is the legacy DES (LDES). See 
    id.
     ¶ 4–
    1(d)(1). The LDES process consists of two steps.
    At the first step, “[w]hen a commander believes that a
    soldier of his or her command is unable to perform the[ir]
    duties,” the commander “refer[s] the soldier to the responsible
    [treatment facility] for evaluation.” Dep’t of the Army, Army
    Regul. 635-40, Physical Evaluation for Retention, Retirement,
    or Separation ¶ 4–8 (1990) (1990 Army Regul. 635-40). After
    that evaluation, if the soldier appears “not medically qualified
    to perform duty,” the soldier goes before a Medical Evaluation
    Board (MEB). 
    Id.
     ¶ 4–9. The MEB then makes a decision “as
    to the soldier’s medical qualification for retention.” 
    Id.
     ¶ 4–10;
    see also 2017 Army Regul. 635-40 ¶ 4–7(a). If the MEB
    determines the soldier does not meet retention standards, it will
    recommend referral of the soldier to a Physical Evaluation
    Board (PEB). 1990 Army Regul. 635-40 ¶ 4–10.
    The PEB’s review is the second step of the process. The
    PEB initially determines whether the soldier is physically fit or
    unfit to perform the duties of their role. 
    Id.
     ¶ 4–19(a)(1); 2017
    Army Regul. 635-40 ¶¶ 4–19, 4–22, 5–1. If the soldier is unfit,
    5
    the PEB then decides the percentage rating for each “unfitting
    compensable disability,” using the Veteran’s Administration
    Schedule for Rating Disabilities (VASRD). See 1990 Army
    Regul. 635-40 ¶ 4–19(i); 38 C.F.R. ch. 1, pt. 4 (VASRD). The
    VASRD contains a schedule of medical conditions, each
    identified by a diagnostic code and assigned a disability rating
    percentage or range of percentages. See, e.g., 
    38 C.F.R. § 4
    .71a.
    “An unfitting, or ratable condition, is one which renders
    the soldier unable to perform [his] duties . . . in such a way as
    to reasonably fulfill the purpose of his or her employment on
    active duty.” 1990 Army Regul. 635-40 ¶ 3–5(c). Under the
    applicable regulations, a finding of unfitness may be based on
    the effect of one disability standing alone or on “the combined
    effect of two or more disabilities.”            
    Id.
     ¶ 4–19(f)(4).
    Correspondingly, a disability is compensable either if it, “in
    itself, is unfitting or [if it] contributes to the unfitting
    condition.” 
    Id.
     ¶ 4–19(f)(6)(b). If the PEB finds that a
    particular condition neither itself renders the soldier unfit nor
    contributes to a finding of unfitness, the Board must list that
    condition with an annotation indicating that the condition is
    “non-ratable.” 
    Id.
     ¶ 3–5(d).
    In 2008, Congress codified those principles, requiring the
    Secretary (and by extension the Boards that conduct the
    LDES), “[i]n making a determination of the rating of
    disability,” to “take into account all medical conditions,
    whether individually or collectively, that render the member
    unfit.” 10 U.S.C. § 1216a(b). Army regulations similarly
    provide that a soldier may be determined unfit based on “the
    overall effect of two or more impairments even though each of
    them, standing alone, would not cause the Soldier to be found
    unfit because of physical disability.” 2017 Army Regul.
    635-40 ¶ 5–4(g). Additionally, “unfitness due to overall or
    6
    combined effect may include one or more conditions
    determined to be unfitting in combination with an
    independently unfitting condition.” Id.
    If a soldier concurs with the PEB’s rating decisions, the
    PEB’s recommendation is finalized and approved on behalf of
    the Secretary of the Army. Since 2008, however, a soldier
    discharged between September 11, 2001, and December 31,
    2009, with a disability rating percentage of 20% or less may
    appeal to the Physical Disability Board of Review (PDBR).
    The PDBR was established pursuant to the National Defense
    Authorization Act for Fiscal Year 2008, 
    Pub. L. No. 110-181, § 1643
    , 
    122 Stat. 3
    , 465–67 (codified at 10 U.S.C. § 1554a), to
    “address the disparities in the disability ratings issued by the
    military departments in the Department of Defense and the
    VA” during that period.        U-Ahk-Vroman-Sanchez v. U.S.
    Dep’t of Def., No. 19-cv-3141, 
    2021 WL 394811
    , at *2 (D.D.C.
    Feb. 4, 2021).
    Following its review, the PDBR may “recommend to the
    Secretary” the issuance of a new disability rating, the
    modification of a previous rating, the recharacterization of a
    soldier’s separation to include medical retirement, or no
    change. See 10 U.S.C. § 1554a(d)(1)–(4). If the PDBR “makes
    a recommendation not to correct the military records,” its
    recommendation is final. Id. § 1554a(e)(3). Otherwise, the
    Secretary “may correct the military records” pursuant to the
    PDBR’s recommendation. Id. § 1554a(e)(1).
    At that point, if the soldier remains dissatisfied with the
    Secretary’s determination, he may seek judicial review under
    the Administrative Procedure Act. See 
    5 U.S.C. § 702
    .
    
    7 C. 1
    .
    Jason Sissel enlisted in the Army and was deployed to Iraq
    during Operation Iraqi Freedom. In 2003, Sissel was involved
    in a motor vehicle accident, suffering injuries to his back and
    right leg. He underwent spinal fusion surgery but continued to
    suffer significant back pain along with pain and weakness in
    his right leg.
    In February 2005, Sissel’s surgeon recommended that an
    MEB assess Sissel to determine his ability to perform his
    duties. An MEB was convened the next month. The MEB
    diagnosed Sissel with degenerative disc disease of the lumbar
    spine, as well as dense hypesthesia (numbness) of the right foot
    and mild weakness in the right leg. See Sissel v. McCarthy, No.
    19-cv-356, 
    2021 WL 6062832
    , at *3 (D.D.C. Dec. 22, 2021).
    The MEB determined that Sissel failed to meet retention
    standards and referred him to a PEB.
    In June 2005, a PEB was convened to review Sissel’s
    fitness to serve. The PEB’s report described Sissel’s disability
    as “chronic back pain and right-leg weakness.” Sissel, 
    2021 WL 6062832
    , at *3 (quotation marks omitted). The report
    linked the disability to a single VASRD code (number 5241),
    which covers spinal fusions. See 
    38 C.F.R. § 4
    .71a. The PEB
    concluded that Sissel’s injuries prevented his performance of
    duty. Sissel, 
    2021 WL 6062832
    , at *3. The Board
    recommended a combined disability rating percentage of 10%
    under VASRD code 5241 and a disposition of separation with
    only severance pay. See 
    id.
     The PEB’s report did not annotate
    any conditions as not contributing to unfitness and thus non-
    ratable.
    8
    Sissel concurred with the PEB’s decision, and the decision
    then was finalized on behalf of the Secretary. In October 2005,
    the Army honorably discharged Sissel.
    2.
    While Sissel worked his way through the LDES, he also
    applied to the Department of Veterans Affairs for disability
    benefits based on the same injuries. VA disability benefits are
    distinct from and offset medical severance and retirement
    benefits. See 
    10 U.S.C. § 1212
    (d); 
    38 U.S.C. §§ 5304
    –05.
    The VA diagnosed Sissel with chronic back pain and a
    right leg injury associated with the back injury. Based on that
    diagnosis, the VA assigned two disability ratings under two
    separate VASRD codes. Under the first code, the VA rated
    Sissel as 20% disabled for his back injury. And under the
    second code, the VA rated him as 10% disabled for his right
    leg injury. The VA thus assigned a total rating percentage of
    30%.
    3.
    Years later, in 2014, Sissel requested that the PDBR
    increase his disability rating from 10% to 30%. He maintained
    that the PEB should have assigned his back injury a 20% rating,
    as the VA had done, rather than the 10% the PEB had assigned
    in 2005. He further contended that the PEB erroneously failed
    to separately rate his leg condition at 10%.
    The PDBR recommended granting Sissel’s request to raise
    his back injury rating to 20% but declining to assign his leg
    injury a separate rating. The updated, recommended total
    disability rating thus was 20%, still not enough to qualify for
    medical retirement. In assessing the PEB’s decision to
    9
    combine Sissel’s back and leg injuries under a single VASRD
    Code, the PDBR explained that the combined rating reflected
    the PEB’s judgment that the constellation of his conditions
    rendered him unfit. The Deputy Assistant Secretary, on behalf
    of the Secretary, accepted the PDBR’s recommendation.
    4.
    In 2019, Sissel sued the Secretary in the district court,
    alleging that the Secretary’s decision to adopt the PDBR’s
    recommendation was arbitrary, unsupported by substantial
    evidence, and contrary to law. The parties jointly moved for a
    remand to the PDBR to reconsider Sissel’s disability rating,
    and the district court granted the motion.
    The PDBR engaged in a “de novo reconsideration” on
    remand but ultimately made the same recommendation: a 20%
    total rating, with no separate rating for the leg injury. Sissel,
    
    2021 WL 6062832
    , at *4 (quotation marks omitted). The
    PDBR again explained that the PEB’s decision to combine
    Sissel’s back and leg conditions under a single disability rating
    reflected a judgment that “‘the constellation of [his] conditions’
    rendered him unfit for duty.” 
    Id.
     The PDBR added that it
    considered each “bundled condition[]” to be “reasonably
    justified as separately unfitting” unless a preponderance of
    evidence indicates the condition would not cause the member
    to be found unfit. 
    Id.
     (alteration in original) (quotation marks
    omitted). The PDBR reached the same conclusion as it had
    before: “the back condition was reasonably considered
    unfitting at separation, but the preponderance of evidence
    showed the [leg injury] would not have, on its own, caused
    [Sissel] to be . . . found unfit.” 
    Id.
     at *4 n.16.
    The Deputy Assistant Secretary, acting on the Secretary’s
    behalf, accepted the PDBR’s recommendation. The Deputy
    10
    Assistant Secretary also reviewed an informal review of
    Sissel’s case conducted by a doctor who was an advisor for the
    Army Review Boards Agency. That doctor determined that
    Sissel’s right-leg condition would require its own rating if it
    either “contributed significantly to the finding of unfitness” or
    was “an absolute stand-alone unfitting condition.” See Sissel,
    
    2021 WL 6062832
    , at *5 (quotation marks omitted). Finding
    neither of those to be true of Sissel’s right-leg condition, the
    doctor concluded that his unfitness instead was predominantly
    due to his back condition. See 
    id.
     The Deputy Assistant
    Secretary likewise determined that Sissel’s right-leg condition
    was neither separately unfitting nor contributed “significantly”
    to his unfitness.
    Sissel’s suit then returned to the district court, which
    granted summary judgment to the Secretary. The court held
    that the Secretary’s decision was not contrary to law, and the
    court further held that the Secretary’s decision was adequately
    explained and supported by substantial evidence. See 
    id.
     at *7–
    13.
    II.
    A.
    Before addressing Sissel’s challenges to the Secretary’s
    decision, we first consider the appropriate standard of review.
    The Secretary submits that we should conduct an “unusually
    deferential application” of Administrative Procedure Act
    review. Sec’y Br. 28. We disagree.
    We have said that “[i]t is the longstanding practice of this
    court to review a decision of a military corrections board under
    an ‘unusually deferential application of the “arbitrary or
    capricious” standard’ of the APA.” Roberts v. United States,
    11
    
    741 F.3d 152
    , 158 (D.C. Cir. 2014) (quoting Kreis v. Sec’y of
    the Air Force, 
    866 F.2d 1508
    , 1514 (D.C. Cir. 1989)). We
    articulated that approach in Kreis, which involved a challenge
    to a decision of the Air Force Board for the Correction of
    Military Records. The statute empowering military corrections
    boards, 
    10 U.S.C. § 1552
    (a)(1), allows for correction of “any
    military record . . . when the Secretary considers it necessary
    to” do so. 
    10 U.S.C. § 1552
    (a)(1) (emphasis added). That
    language, we reasoned, “substantially restrict[ed] the authority
    of the reviewing court to upset the Secretary’s determination”
    because “[i]t is simply more difficult to say that the Secretary
    has acted arbitrarily if he is authorized to act ‘when he
    considers it necessary.’” Kreis, 866 F,2d at 1514 (quoting 
    10 U.S.C. § 1552
    (a)(1)). We thus concluded that “decisions of the
    Board are reviewable under the APA, albeit by an unusually
    deferential application of the ‘arbitrary and capricious’
    standard.” 
    Id.
    The question here is whether the statute empowering the
    PDBR, 10 U.S.C. § 1554a, exudes similarly unusual deference
    to the Secretary. Under that statute, the PDBR “may . . .
    recommend to the Secretary” that a separation be
    recharacterized or a rating be modified or issued and the
    Secretary “may correct the military records . . . in accordance
    with a recommendation made by the [PDBR].” 10 U.S.C.
    § 1554a(d), (e)(1) (emphasis added). True, the statute’s use of
    “may” indicates that the PDBR and the Secretary have the
    discretion, rather than the obligation, to act. See, e.g., Biden v.
    Texas, 
    142 S. Ct. 2528
    , 2541 (2022). But a great deal of agency
    action is discretionary, and the default standard of review still
    is ordinary arbitrary-and-capricious review. In Kreis, we
    concluded that an unusually deferential application of that
    standard was warranted because section 1552(a)(1) confers
    uncommon discretion by authorizing the Secretary to act when
    she “considers it necessary.” 
    10 U.S.C. § 1552
    (a)(1); see
    12
    Kreis, 866 F.3d at 1514.           Section 1554a contains no
    comparable language.
    Contrary to the Secretary’s contention, our reliance on
    ordinary arbitrary-and-capricious review should not threaten to
    “destabilize military command and take the judiciary far afield
    of its area of competence.” Cone v. Caldera, 
    223 F.3d 789
    ,
    793 (D.C. Cir. 2000). To be sure, determining whether a
    condition renders a soldier unfit for service calls for military
    judgment. But the cases in which we have emphasized the need
    for a heightened standard of review to safeguard military
    judgment have involved decisions concerning active personnel,
    such as performance reviews and promotion decisions. See,
    e.g., Roberts, 
    741 F.3d at
    155–57; Cone, 
    223 F.3d at
    790–92;
    Kreis, 
    866 F.2d at 1509
    . The PDBR, however, is tasked with
    reviewing disability rating decisions that will determine the
    compensation of soldiers who left the military no later than
    2009. See 10 U.S.C. § 1554a(b). Reviewing those decisions
    under ordinary arbitrary-and-capricious review would not
    “destabilize military command.” Cone, 
    223 F.3d at 793
    .
    Of course, even ordinary arbitrary-and-capricious review
    is “[h]ighly deferential” and “presumes the validity of agency
    action.” AT&T Corp. v. FCC, 
    220 F.3d 607
    , 616 (D.C. Cir.
    2000). The Secretary’s decision is thus entitled to that kind of
    deference.
    B.
    We now turn to the Secretary’s decision. The PDBR’s
    recommendation, which the Secretary accepted, is amenable to
    more than one interpretation. But no matter how one reads that
    recommendation, the Secretary, in accepting it, did not act in
    accordance with the law governing disability ratings. The
    Secretary either (i) concluded that Sissel’s leg condition
    13
    contributed to his unfitness but nonetheless did not assign it a
    disability rating, or (ii) concluded that Sissel’s leg condition
    was not unfitting because it neither separately rendered Sissel
    unfit nor “significantly” contributed to his unfitness. Either
    way, the Secretary’s decision was contrary to law.
    1.
    Certain aspects of the PDBR’s recommendation suggest a
    conclusion that Sissel’s leg condition contributed to his
    unfitness together with his back injury. According to the
    PDBR, the PEB had determined that the “constellation” of
    Sissel’s back and leg injuries was unfitting. Sissel, 
    2021 WL 6062832
    , at *4. The record contains support for the PDBR’s
    understanding of the PEB’s decision. The PEB listed both of
    Sissel’s injuries—chronic back pain and right leg weakness—
    under a single diagnostic code. 
    Id.
     Importantly, in listing both
    conditions under a single code, the PEB did not annotate the
    leg condition as non-ratable. Under the relevant regulations,
    that omission indicates that the PEB found the two conditions
    collectively unfitting. See 1990 Army Regul. 635-40 ¶ 3–5(d).
    To the extent the PEB found Sissel’s right-leg condition
    collectively unfitting, the PDBR’s ensuing recommendation in
    some respects suggests agreement that Sissel’s leg condition
    contributed to his unfitness together with his back condition.
    The PDBR undoubtedly found the latter condition separately
    unfitting: after “de-coupl[ing]” the back and leg conditions,
    the PDBR concluded that “the back condition was reasonably
    considered unfitting at separation” and assigned “a disability
    rating of 20% for the back condition, coded 5241.” Sissel, 
    2021 WL 6062832
    , at *4 n.16. But the PDBR did not expressly
    disclaim the PEB’s explanation that the “constellation” of
    Sissel’s back and leg injuries also was unfitting. Moreover, the
    PDBR recommended a 20% disability rating “for the combined
    14
    conditions of ‘back pain and right leg weakness,’” 
    id. at *4
    (emphasis added), consistent with a conclusion that Sissel’s leg
    injury contributed to unfitness together with his back condition.
    If the PDBR concluded that Sissel’s leg injury, along with
    his back injury, was collectively unfitting, the PDBR was
    obligated to give Sissel’s leg condition a rating. But the PDBR
    did not do so, meaning the Secretary acted contrary to law in
    adopting the PDBR’s conclusion.
    Longstanding Army regulations confirm an obligation to
    rate any compensable disability—that is, any disability that “in
    itself, is unfitting or contributes to the unfitting condition.”
    1990 Army Regul. 635-40 ¶ 4–19(f)(6)(b) (emphasis added);
    see also 
    id. ¶ 4-19
    (i); 2017 Army Regul. 635-40 ¶ 5–5. That is
    so even if, as here, one of the conditions in the constellation of
    collectively unfitting conditions would also, on its own, suffice
    to render the soldier unfit. See 2017 Army Regul. 635-40 ¶ 5–
    4(g). To the same effect, the governing statute establishes that,
    “[i]n making a determination of the rating of disability of a
    member of the armed forces . . . , the Secretary concerned shall
    take into account all medical conditions, whether individually
    or collectively, that render the member unfit.” 10 U.S.C.
    § 1216a(b) (emphasis added).
    Thus, to the extent the PDBR concluded that Sissel’s leg
    condition rendered him collectively unfit when considered
    together with his back condition, it was obligated to assign a
    rating to the leg condition. By extension, the Secretary, in
    accepting the PDBR’s recommendation to give no rating to
    Sissel’s leg condition, acted contrary to law insofar as the
    PDBR concluded that his leg condition was collectively
    unfitting together with his back condition.

    2.
    In certain respects, however, the PDBR indicated that
    Sissel’s leg condition did not contribute to his unfitness—i.e.,
    that it was not collectively unfitting together with his back
    condition. Most notably, the PDBR stated that Sissel’s
    “decreased RLE [right lower extremity] sensation would not be
    anticipated to have any impact on [Sissel’s] duty performance
    and there was no evidence in the record that it did.” Sissel,
    
    2021 WL 6062832
    , at *4 n.16 (emphasis added). And the
    Secretary, in adopting the PDBR’s recommendation, said that
    she concurred that Sissel’s leg condition was not separately
    unfitting and did not contribute to his unfitness.
    Insofar as the Secretary determined that Sissel’s leg
    condition was not collectively unfitting, though, the Secretary
    referenced too stringent a standard. The Secretary, echoing the
    conclusion of the doctor whose informal advice the Secretary
    reviewed, stated that Sissel’s leg condition did not contribute
    “significantly” to his unfitness. Sissel, 
    2021 WL 6062832
    , at
    *5. But according to the terms of the Army’s regulations, any
    “contribution”—regardless of level of significance—calls for a
    rating. See 1990 Army Regul. 635-40 ¶ 4–19(f)(6)(b); 2017
    Army Regul. 635-40 ¶ 5–5. That is also the most natural
    reading of the relevant statute: when multiple conditions
    “collectively . . . render the member unfit,” the Secretary “shall
    take into account all” of those medical conditions. 10 U.S.C.
    § 1216a(b) (emphasis added). The fact that a condition
    contributes to a soldier’s unfitness is enough, and the
    Secretary’s apparent addition of a “significantly” criterion
    naturally raises questions about what degree and manner of
    contribution is thought to suffice, questions that the terms of
    the statute and regulations do not make salient.
    16
    The Secretary’s “significantly” add-on is also undermined
    by the fact that, under the LDES, the insignificance of a
    condition that contributes to unfitness is taken into account in
    the rating ultimately assigned to the condition, not in whether
    the condition should get any rating in the first place. The
    applicable regulations explain that, “[o]ccasionally a medical
    condition which . . . contributes to unfitness for military
    service is of such mild degree that it does not meet the criteria
    for even the lowest rating provided in the VASRD.” 1990
    Army Regul. 635-40 app. ¶ B–15. In that situation, the
    regulations instruct the PEB to generally “[a]pply a 0 percent
    rating” even though the condition does contribute (albeit
    mildly) to the soldier’s unfitness. Id. The regulations thus
    presume that every condition contributing to unfitness—no
    matter how insignificant the contribution—receives a rating,
    even if a rating of 0. That is inconsistent with the Secretary’s
    indication that Sissel’s leg condition was not unfitting (and
    hence non-ratable) because it did not “significantly” contribute
    to his unfitness. Any assumption that a medical condition, to
    receive a rating, must contribute “significantly” to unfitness
    thus is contrary to law.

    For the foregoing reasons, we vacate the district court’s
    grant of summary judgment and remand for further
    proceedings consistent with this opinion.
    So ordered.
