    Before: MILLETT, RAO, and CHILDS, Circuit Judges.
    Opinion for the Court filed by Circuit Judge MILLETT.
    MILLETT, Circuit Judge: Jaskirat Singh, Milaap Singh
    Chahal, and Aekash Singh wish to serve their Nation by
    enlisting in the United States Marine Corps. They are each
    fully qualified to enlist, having satisfied the Corps’ pre-
    enlistment criteria. There is just one barrier to their entry.
    Jaskirat, Milaap, and Aekash are members of the Sikh faith,
    which requires them, as relevant here, to maintain unshorn hair
    and beards and to wear certain articles of faith. Those religious
    practices conflict with the Marine Corps’ standard grooming
    policy for the initial training of newly enlisted recruits,
    3
    commonly known as boot camp. The Corps has agreed to
    accommodate Plaintiffs’ religious commitments (with some
    limitations not relevant here) after each of them finishes basic
    training. But it will brook no exception for the Sikh faith
    during those initial thirteen weeks of boot camp.
    The district court denied Plaintiffs’ request for a
    preliminary injunction based solely on an analysis of the public
    interest. We reverse in part and remand for the prompt issuance
    of a preliminary injunction in favor of Jaskirat Singh and
    Milaap Chahal, and for reconsideration of Aekash Singh’s
    request for a preliminary injunction in light of this opinion.
    I
    A
    This case arises at the intersection of weighty competing
    interests. On the one hand, “no military organization can
    function without strict discipline and regulation that would be
    unacceptable in a civilian setting.” Chappell v. Wallace, 
    462 U.S. 296
    , 300 (1983). Plus the “complex, subtle, and
    professional decisions as to the composition, training,
    equipping, and control of a military force are essentially
    professional military judgments” that courts generally are ill-
    equipped to second guess. Gilligan v. Morgan, 
    413 U.S. 1
    , 10
    (1973); see also Winter v. Natural Res. Def. Council, Inc., 
    555 U.S. 7
    , 24 (2008). To inculcate the importance to service
    members of sacrificing “personal preferences and identities in
    favor of the overall group mission[,]” the military has long had
    an interest in “the strict enforcement of its uniform dress
    requirements.” Goldman v. Weinberger, 
    475 U.S. 503
    , 504,
    508 (1986).
    4
    On the other hand, the cost of military service has never
    entailed the complete surrender of all “basic rights[.]”
    Chappell, 
    462 U.S. at 304
     (internal quotation marks and
    citation omitted); see also Rostker v. Goldberg, 
    453 U.S. 57
    ,
    67 (1981) (“[W]hen it acts in the area of military affairs,”
    “Congress remains subject to the limitations of the Due Process
    Clause[.]”); Parker v. Levy, 
    417 U.S. 733
    , 758 (1974)
    (“[M]embers of the military are not excluded from the
    protection granted by the First Amendment[.]”).
    Of particular relevance here, in exercising their “plenary
    constitutional authority over the military,” see Chappell, 
    462 U.S. at 302
    , the Political Branches have repeatedly required the
    military to carefully balance its need for disciplined uniformity
    with the religious needs of service members.
    For example, Congress responded promptly and directly
    to the Supreme Court’s decision in Goldman v. Weinberger,
    
    475 U.S. 503
     (1986), which rejected a service member’s First
    Amendment claim to wear a yarmulke while in uniform, 
    id.
     at
    509–510. A statute passed the following year instructed the
    military not to ban religious apparel in uniform unless it would
    “interfere with the performance of the member’s military
    duties” or disrupt a “neat and conservative” appearance. See
    Pub. L. No. 100–180 § 508, 
    101 Stat. 1019
    , 1086–1087 (1987)
    (codified at 
    10 U.S.C. § 774
    ).
    Then, in 1993, Congress enacted the Religious Freedom
    Restoration Act (“RFRA”), Pub. L. No. 103–141 (codified at
    42 U.S.C. § 2000bb et seq.). RFRA prohibits the federal
    government from “substantially burden[ing] a person’s
    exercise of religion” unless the Government “demonstrates that
    application of the burden to the person” is the “least restrictive
    means” of furthering a “compelling” interest. See 42 U.S.C.
    § 2000bb–1(b)(1)–(2). As the Government has recognized,
    5
    RFRA, with its demanding compelling-interest and least-
    restrictive-means test, “undoubtedly ‘applies in the military
    context.’” United States Navy Seals 1–26 v. Biden, 
    27 F.4th 336
    , 346 (5th Cir. 2022) (quoting United States v. Sterling, 
    75 M.J. 407
    , 410 (C.A.A.F. 2016), cert. denied, 
    137 S. Ct. 2212
    (2017)); see also Application for Partial Stay at 22–24, Austin
    v. United States Navy Seals 1–26, No. 21A477, 
    142 S. Ct. 1301
    (March 7, 2022) (government acknowledging that RFRA
    applies to military decisionmaking); Religious Liberty in the
    Military Services, Department of Defense Instruction 1300.17
    at 1–3 (Jan. 22, 2014) (applying 42 U.S.C. § 2000bb–1 to
    religious accommodations); Religious Liberty in the Military
    Services, Department of Defense Instruction 1300.17 at 1–2
    (Sept. 1, 2020), J.A. 548–549 (describing its purpose as, in part,
    to “[i]mplement[] requirements” of RFRA and “to provide, in
    accordance with the RFRA, that DoD Components will
    normally accommodate practices of a Service member based
    on a sincerely held religious belief”).
    As the Supreme Court has explained, “Congress’s express
    decision to legislate the compelling interest test indicates that
    RFRA challenges should be adjudicated in the same manner as
    constitutionally mandated applications of the test, including at
    the preliminary injunction stage.” Gonzales v. O Centro
    Espirita Beneficiente União do Vegetal, 
    546 U.S. 418
    , 429–430
    (2006) (“O Centro”). As under the First Amendment, RFRA’s
    “compelling interest test” is an “affirmative defense” for which
    the Government bears the burden of persuasion, and it subjects
    governmental action to strict scrutiny. See O Centro, 
    546 U.S. at 424
    , 429–430. Strict scrutiny is an “exceptionally
    demanding” test. Holt v. Hobbs, 
    574 U.S. 352
    , 364 (2015)
    (quoting Burwell v. Hobby Lobby Stores, Inc., 
    573 U.S. 682
    ,
    728 (2014)). If the Government can achieve its interests
    without burdening religion, “it must do so.” Fulton v. City of
    Philadelphia, 
    141 S. Ct. 1868
    , 1881 (2021); see also Hobby
    6
    Lobby, 573 U.S. at 728. By subjecting military decisions to
    RFRA scrutiny, the Political Branches determined, in their
    expert judgment, that Americans need not surrender their faith
    to fight for their Nation absent demonstrated necessity.
    Since RFRA, Congress and multiple Presidents have
    doubled down on their commitment to accommodating religion
    within military life. In the National Defense Authorization Act
    for Fiscal Year 2013, Congress specifically instructed the
    military to accommodate the “conscience, moral principles, or
    religious beliefs” of service members and forbade any
    disciplinary action based on such beliefs to the extent
    “practicable.” See Pub. L. No. 112–239 § 533(a)(1) (codified
    at note preceding 
    10 U.S.C. § 1030
    ). Congress expanded that
    protection the following year by narrowing the grounds on
    which the military could justify disciplinary action and by
    requiring an Inspector General report on freedom of religion
    and conscience in the military. See National Defense
    Authorization Act for Fiscal Year 2014, Pub. L. No. 113–66
    §§ 532–533, 
    127 Stat. 672
    , 759–760.
    Most recently, in 2015, the Political Branches expressly
    acknowledged the “numerous religious traditions” represented
    among service members, including “Christian, Hindu, Jewish,
    Muslim, [and] Sikh,” and determined that this diversity
    “contributes to the strength” of the armed forces and should be
    “promote[d].” National Defense Authorization Act for Fiscal
    Year 2016, Pub. L. No. 114–92 § 528, 
    129 Stat. 726
    , 814; see
    also JOSEPH R. BIDEN, NATIONAL SECURITY STRATEGY 21
    (Oct. 2022) (“We will strengthen the effectiveness of the force
    by promoting diversity and inclusion[.]”).
    Citing RFRA, and in line with those directives, the Army,
    Navy, Air Force, and Coast Guard, as well as their training
    Academies, each accommodate the Sikh religious practices at
    7
    issue here during both initial recruit training and military
    service.     Department of the Navy Bureau of Personnel
    Instruction (BUPERSINST) 1730.11A at 4, 9 (March 16,
    2020); Army Directive 2017–03 at 1, 3–5 & Enclosure at 2–4
    (Jan. 3, 2017); Department of the Air Force Instruction 36–
    2903 at 148 (Feb. 7, 2020); Coast Guard Commandant
    Instruction (COMDTINST) 1000.15 at 4–6 (Aug. 30, 2021).
    The Marine Corps, though, has refused in this case to
    make a religious exception to its uniform and grooming
    requirements for Plaintiffs during boot camp. The Corps’
    Uniform Regulations require men ordinarily to keep “clean-
    shaven” faces and prohibit wearing religious articles absent
    authorization. See Marine Corps Order 1020.34H §§ 1001 ¶ 6,
    1004 ¶ 4 (May 1, 2018) (“Marine Corps Uniform
    Regulations”). Also, during boot camp, a male recruit must
    weekly “have his entire hair length clipped to the scalp[.]” Id.
    § 1004 ¶ 7a(1)(a)(2); Jeppe Decl. ¶ 17, J.A. 721.
    B
    Sikhism is a monotheistic faith with over 25 million
    adherents worldwide, making it the fifth-largest religion in the
    world. Religious Accommodations in the Armed Forces:
    Hearing Before the H. Comm. on Armed Services, 113th Cong.
    107 (2014) (statement for the record of the Sikh Coalition)
    (“Sikh Coalition Testimony”). Plaintiffs, like many Sikhs,
    view their faith as one of “courageous warriors against
    injustice,” Compl. ¶ 184, J.A. 39, and Sikhs have served with
    distinction in the United States military since at least World
    War I, Sikh Coalition Testimony at 108.
    As relevant here, Sikhism forbids its adherents to cut the
    hair on their head or to shave the hair on their face (kesh) and
    requires men to wear a turban or a patka (a smaller covering)
    8
    over their heads. See Compl. ¶¶ 78–79, 82, J.A. 25–26; Sikh
    Coalition Testimony at 107. Adherents also must wear a
    specific metal bracelet (kara). Compl. ¶ 79, J.A. 25–26.
    Additionally, those who have gone through an initiation
    ceremony must carry a small ceremonial dagger under their
    clothes (kirpan), wear specific undershorts (kacchera), and
    insert a small ceremonial comb in their hair (kanga). Compl.
    ¶ 79, J.A. 25–26; Pl. Opening Br. 10 n.4; see also Tagore v.
    United States, 
    735 F.3d 324
    , 328–329 (5th Cir. 2013)
    (discussing the kirpan); Cheema v. 
    Thompson, 67
     F.3d 883,
    884 (9th Cir. 1995) (discussing Sikh articles of faith),
    overruled on other grounds by City of Boerne v. Flores, 
    521 U.S. 507
     (1997). All three plaintiffs may not shave their hair
    and must wear a patka or turban over their heads and a bracelet.
    Milaap Chahal, having gone through the initiation ceremony,
    also must wear the dagger, undershorts, and comb. Pl. Opening
    Br. 10–11 n.4.
    Plaintiffs are lifelong Sikhs for whom the failure to
    comply with those faith obligations would be intolerable.
    Cutting one’s hair, for example, is “as reprehensible as
    adultery,” as Milaap Chahal attested in his administrative
    appeal. J.A. 170. Throughout history, Sikhs have chosen death
    over cutting their hair. Compl. ¶ 85, J.A. 27; see also Sikh
    Coalition Testimony at 107 (“[D]enying a Sikh the right to
    wear a turban and maintain unshorn hair * * * is perceived by
    followers as the most humiliating and hurtful physical injury
    that can be inflicted upon a Sikh.”).
    Between March and November of 2021, Jaskirat Singh,
    Milaap Chahal, and Aekash Singh sought to enlist in the
    Marine Corps. They each passed the Armed Services
    Vocational Battery test, and were otherwise “found to be
    mentally, morally, and physically qualified for accession in to
    the Marine Corps.” Marine Corps Instruction 1730.9 § 4.3
    9
    (July 12, 2021) (defining a “qualified applicant”); Defs.’
    Answer ¶ 27, J.A. 748 (agreeing that Plaintiffs “have been
    determined to be ‘qualified applicants’ for accession pursuant
    to Marine Corps Order 1730.9”); id. ¶¶ 62–63, 138, 205, J.A.
    752, 760, 767. Each then submitted a pre-accession request for
    a waiver of the requirement that they shave their heads and
    faces, and permission to cover their heads with a turban or
    patka and wear a bracelet. Milaap Chahal also asked to be
    allowed to carry the additional articles of faith under his
    uniform.
    The Marine Corps granted each request in part on
    substantially identical terms. Citing its “compelling interest”
    in “instilling in each Marine an identity as part of a team” and
    in “break[ing] down recruits’ individuality,” the Corps
    withheld all accommodations during the thirteen-week basic
    training program. J.A. 59; J.A. 165–166; J.A. 236. But the
    Corps committed to allowing Plaintiffs to wear unshorn hair,
    neatly tied beards, turbans or patkas, and a steel bracelet after
    basic training, except “when receiving hostile fire pay or
    imminent danger pay,” or when a battalion or squadron
    commander determines that “operational necessity” requires a
    suspension. J.A. 59; J.A. 164; J.A. 236. Chahal’s request to
    wear religious undershorts, a comb, and a ceremonial dagger
    also was only granted for after basic training, and subject to
    similar conditions. J.A. 165.
    Each Plaintiff timely filed an administrative appeal that
    has remained pending for ten to fourteen months.
    After receiving no further response on their administrative
    appeals, Plaintiffs filed suit in April 2022 against the
    Commandant of the Marine Corps and other senior Department
    of Defense officials. As relevant here, the complaint alleges
    that the Marine Corps’ denial of their requested
    10
    accommodations during recruit training violates RFRA and the
    First Amendment. Two days after filing their complaint,
    Plaintiffs filed a motion for a preliminary injunction “allowing
    them to maintain their hair, beards, and religious articles
    (including the turban) during recruit training and for the
    pendency of this case.” Mot. Prelim. Inj. at 19, ECF No. 16,
    Toor v. Berger, No. 22–1004 (D.D.C. April 13, 2022).
    The district court denied preliminary relief. While
    recognizing that the Government faced a strict-scrutiny burden
    under RFRA, the district court found it “unnecessary” to
    address the Plaintiffs’ likelihood of success on the merits or
    their irreparable injury because the Government “credibly
    alleged” that granting the preliminary injunction would “pose
    a serious threat to national security” by disrupting training
    methods. Mem. Op. 10–12, J.A. 822–824.
    Plaintiffs filed an interlocutory appeal and subsequently
    moved for an injunction pending appeal or, in the alternative,
    an expedited appeal. We granted expedition. We have
    jurisdiction under 
    28 U.S.C. § 1292
    (a)(1).
    II
    A preliminary injunction is an extraordinary remedy that
    requires a moving party to make a “clear showing” that (1) it
    has a likelihood of success on the merits, (2) the balance of
    equities favors preliminary relief, (3) an injunction is in the
    public interest, and (4) it will likely suffer irreparable harm
    before the district court can resolve the merits of the case. See
    Archdiocese of Wash. v. Washington Metro. Area Transit
    Auth., 
    897 F.3d 314
    , 321 (D.C. Cir. 2018) (quoting League of
    Women Voters v. Newby, 
    838 F.3d 1
    , 6 (D.C. Cir. 2016)); see
    also Winter, 
    555 U.S. at 22
    .
    11
    Preliminary injunctions are generally a “stopgap measure”
    meant only to “preserve the relative positions of the parties”
    until trial. Sherley v. Sebelius, 
    689 F.3d 776
    , 781–782 (D.C.
    Cir. 2012) (quotation omitted). After all, “deciding whether to
    grant a preliminary injunction is normally to make a choice
    under conditions of grave uncertainty.” O Centro Espirita
    Beneficiente União do Vegetal v. Ashcroft, 
    389 F.3d 973
    , 1015
    (10th Cir. 2004) (en banc) (McConnell, J., concurring).
    Bearing in mind that a grant of preliminary relief could prove
    to be “mistaken” once the merits are finally decided, id. at
    1017, courts are institutionally wary of granting relief that
    disrupts, rather than preserves, the status quo, especially when
    that relief cannot be undone if the non-movant ultimately wins
    on the merits. Id. at 1014–1015; see Dorfmann v. Boozer, 
    414 F.2d 1168
    , 1173 & n.13 (D.C. Cir. 1969). When the injunction
    addresses military affairs, courts “give great deference to the
    professional judgment of military authorities concerning the
    relative importance of a particular military interest.” Winter,
    
    555 U.S. at 24
     (quoting Goldman, 
    475 U.S. at 507
    ).
    Each of these weighty circumstances is at play in this
    case.    The proposed injunction would alter “the last
    uncontested status” before this suit: the Corps’ longstanding
    policy of refusing to accommodate religious objections to
    shaving during boot camp. See Huisha-Huisha v. Mayorkas,
    
    27 F.4th 718
    , 733 (D.C. Cir. 2022) (emphasis and quotation
    omitted). And Plaintiffs could start and finish their thirteen-
    week training before the district court can render a final
    determination on the merits, making the relief granted
    potentially conclusive on that claim in their complaint.
    Although the Government did not ask the district court or
    this court at the motion stage to apply a heightened standard for
    preliminary relief, many of our sister circuits have adopted
    more stringent criteria for injunctions that alter the status quo
    12
    or grant irreversible relief. See Silvertop Assocs. Inc. v.
    Kangaroo Mfg. Inc., 
    931 F.3d 215
    , 218 n.1 (3d Cir. 2019) (A
    “heightened mandatory injunction standard” applies if the
    injunction “request[s] * * * substantially all of its relief in a
    way that the relief could not later be undone” or does not
    “maintain the status quo.”); Edmo v. Corizon, Inc., 
    935 F.3d 757
    , 784 n.13 (9th Cir. 2019) (“Because mandatory
    preliminary injunctions go well beyond the status quo pendente
    lite, they are particularly disfavored and are not issued in
    doubtful cases.”) (formatting modified and quotation omitted);
    In re Microsoft Corp. Antitrust Litig., 
    333 F.3d 517
    , 526 (4th
    Cir. 2003) (“Mandatory preliminary injunctions [generally] do
    not preserve the status quo and normally should be granted only
    in those circumstances when the exigencies of the situation
    demand such relief.”) (quoting Wetzel v. Edwards, 
    635 F.2d 283
    , 286 (4th Cir. 1980)), abrogated on other grounds by eBay
    Inc. v. MercExchange, LLC, 
    547 U.S. 388
     (2006); Prairie Band
    of Potawatomi Indians v. Pierce, 
    253 F.3d 1234
    , 1246–1250
    (10th Cir. 2001) (noting that a heightened standard applies if
    “the effect of the order, once complied with, cannot be
    undone”) (quotation omitted); Boucher v. Greenfield Sch. Bd.,
    
    134 F.3d 821
    , 826 n.6 (7th Cir. 1998) (“A preliminary
    injunction that would give the movant substantially all the
    relief he seeks is disfavored, and courts have imposed a higher
    burden on a movant in such cases.”); Tom Doherty Assocs., Inc.
    v. Saban Ent., Inc., 
    60 F.3d 27
    , 35 (2d Cir. 1995) (“[I]f a
    preliminary injunction will make it difficult or impossible to
    render a meaningful remedy to a defendant who prevails on the
    merits at trial, then the plaintiff should have to meet the higher
    standard of substantial, or clear showing of, likelihood of
    success to obtain preliminary relief.”).
    While we believe that, on the record before us, Plaintiffs
    would prevail under any of those heightened tests for a
    preliminary injunction, we decline to reformulate the
    13
    traditional test set out by the Supreme Court in Winter, which
    considered preliminary injunctive relief aimed at the military.
    
    555 U.S. at 12, 20
    . Instead, Winter shows that the established
    test for preliminary relief is sufficiently flexible to take account
    of all the concerns implicated by the nature of the relief sought
    here. After all, “[f]lexibility rather than rigidity has [long]
    distinguished” equity jurisdiction. Weinberger v. Romero-
    Barcelo, 
    456 U.S. 305
    , 312 (1982) (quotation omitted).
    Winter, for its part, already obligates courts to carefully
    “balance the competing claims of injury[,]” and to weigh the
    “effect on each party of the granting or withholding of the
    requested relief.” 
    555 U.S. at 24
     (quoting Amoco Prod. Co. v.
    Village of Gambell, 
    480 U.S. 531
    , 542 (1987)). Properly
    understood, the “public consequences [of] employing the
    extraordinary remedy of injunction[,]” Romero-Barcelo, 
    456 U.S. at 312
    , necessarily include the risk that the relief requested
    will cause unusual disruption if granted in error, for example
    by disturbing the status quo in a way that cannot readily be
    undone.
    III
    Applying Winter’s test and taking full account of the
    additional headwinds the Plaintiffs’ request for status-quo-
    altering and potentially claim-concluding relief faces, we hold
    that Jaskirat Singh and Milaap Chahal have clearly
    demonstrated the appropriateness of preliminary injunctive
    relief. They have shown not just a likelihood of success, but
    an overwhelming one, on the merits of their RFRA claim. The
    balance of equities and the public interest weigh strongly in
    favor of issuing the injunction. And they are now suffering and
    will continue to suffer grave, immediate, and ongoing injuries
    to the exercise of their faith. As for Aekash Singh, he shares
    that same likelihood of success and balance of interests, but it
    14
    is unclear on the current record whether he needs injunctive
    relief before the district court can rule on the merits.
    A
    Plaintiffs “not only have a substantial likelihood of success
    on the merits—it is difficult to imagine them losing.” Alabama
    Ass’n of Realtors v. Department of Health & Hum. Servs., 
    141 S. Ct. 2485
    , 2488 (2021).
    RFRA forbids the federal government—including the
    Marine Corps—from “substantially burden[ing] a person’s
    exercise of religion” unless it shows that burden is “in
    furtherance of a compelling governmental interest” and is the
    “least restrictive means” of doing so. 42 U.S.C. §§ 2000bb–
    1(a), (b); O Centro, 
    546 U.S. at 431
    . In meeting that standard,
    the Marine Corps cannot rely on “broadly formulated
    interests.” Hobby Lobby, 573 U.S. at 726 (quoting O Centro,
    
    546 U.S. at 431
    ). Instead, the Corps must demonstrate the
    specific harm that “would”—not could—result from “granting
    specific exemptions to particular religious claimants.” O
    Centro, 
    546 U.S. at 431
     (quoting Wisconsin v. Yoder, 
    406 U.S. 205
    , 236 (1972)); see also United States v. Alvarez, 
    567 U.S. 709
    , 725 (2012) (requiring a causal relationship between the
    restriction imposed and the interest served).
    The Marine Corps does not dispute either the sincerity of
    the Plaintiffs’ faith or the Complaint’s explanation of why
    maintaining unshorn hair and carrying religious articles is an
    inviolable aspect of their religious exercise.
    The Marine Corps also acknowledges that refusing the
    Plaintiffs any religious accommodation during boot camp—
    which is their only route into service in the Corps—imposes a
    substantial burden on the exercise of their faith. See Gov’t
    15
    Opp. Prelim. Inj. at 2, ECF No. 35, Toor v. Berger, No. 22–
    1004 (D.D.C. May 25, 2022) (“[T]he Government does not
    contest for purposes of this motion that Plaintiffs’ request is
    rooted in sincerely held religious beliefs and that conforming
    to the discipline of uniformity during recruit training will
    burden those beliefs.”); see 
    id.
     at 8–9 (arguing only that the
    denial was “the least restrictive means” of furthering “the
    compelling interests of mission accomplishment, unit
    cohesion, and good order and discipline”). The Plaintiffs are,
    in effect, penalized through the outright denial of their desired
    military careers solely for practicing their faith.
    So the Plaintiffs’ likelihood of success comes down to
    whether the Marine Corps has demonstrated a compelling
    interest accomplished by the least restrictive means in refusing
    to accommodate their faith for the thirteen weeks of boot camp.
    The Marine Corps has failed to meet its burden on both fronts.
    1
    We note at the outset that the Marine Corps does not assert
    a compelling interest grounded in any safety concerns for
    Plaintiffs or their fellow recruits arising from the requested
    accommodations. Neither does it argue that the presence of
    unshorn hair or faith articles will interfere physically with the
    boot camp training regimen. Nor does it contend that unshorn
    hair, groomed in compliance with Marine Corps standards and
    covered with a turban or patka, is incompatible with being a
    Marine after boot camp. Quite the opposite: The Marine Corps
    stands ready to accommodate Plaintiffs’ unshorn hair and
    religious articles after boot camp and throughout their careers,
    with limited exceptions not relevant here.              J.A. 59
    (memorandum from David A. Ottignon, Deputy Commandant
    for Manpower and Reserve Affairs, to Jaskirat Singh); J.A.
    165–166 (memorandum from Ottignon to Milaap Chahal); J.A.
    16
    236–237 (memorandum from Ottignon to Aekash Singh); see
    also J.A. 735 (recommendation from Religious
    Accommodation Review Board that the Corps “approve
    [Aekash Singh’s] request following successful completion of
    Recruit Training”); J.A. 739 (same for Jaskirat Singh); J.A. 743
    (same for Milaap Chahal).
    Instead, relying solely on a declaration from Colonel Adam
    Jeppe, a Marine Corps officer involved in denying Plaintiffs’
    accommodation requests, the Marine Corps argues that
    excepting the Plaintiffs from the repeated ritual of shaving their
    faces and heads alongside fellow recruits, and permitting them
    to wear a head covering, will impede its compelling interest in
    forging unit cohesion and a uniform mindset during boot camp.
    Colonel Jeppe explains that uniformity is crucial to the
    “psychological transformation” by which civilians acquire the
    “team mentality,” “willingness to sacrifice,” and “esprit de
    corps” that are “the hallmark of the Marine Corps.” Jeppe
    Decl. ¶¶ 18–19, J.A. 721. This transformation does not require
    that “every [M]arine look[] the same.” Prelim. Inj. Hr’g Tr. at
    17:24–18:1, J.A. 791–792; see also Inj. Pending App. Oral
    Arg. Tr. 33:14–19. Rather, it requires that recruits (1) follow
    “the same set of regimented practices,” Gov’t Br. 33, and (2)
    be “stripped of their individuality,” Gov’t Br. 20 (quoting
    Jeppe Decl. ¶ 17 , J.A. 720). Just as all recruits suspend
    “individual expression, freedom of movement, and freedom of
    dietary choices,” so too, Colonel Jeppe reasons, must Plaintiffs
    shed religious practices that symbolize their individual beliefs.
    Jeppe Decl. ¶ 24, J.A. 723.1
    1
    But see Oral Arg. Tr. 57:23–58:3 (When asked at oral argument
    whether the Marine Corps accommodates dietary restrictions at boot
    camp, counsel for the Corps responded: “My understanding, in
    general, is that * * * the food that is provided generally
    accommodates people’s dietary restrictions.”).
    17
    We fully credit the vital importance of training Marines
    “ready to make the sacrifices necessary” to defend the Nation.
    Jeppe Decl. ¶ 23, J.A. 722. And we tread with great care
    knowing that the “complex, subtle, and professional decisions
    as to the composition[ and] training” of “military force[s]” are
    matters of expert “military judgment[]” assigned to the
    Political Branches rather than to the judiciary. Gilligan, 
    413 U.S. at 10
    ; see Austin v. United States Navy Seals 1–26, 
    142 S. Ct. 1301
    , 1302 (2022) (Kavanaugh, J., concurring). For that
    reason, we “indulge the widest latitude” in considering the
    Marine Corps’ interest in fostering cohesion and unity among
    its members, which surely qualifies as compelling.
    Youngstown Sheet & Tube Co. v. Sawyer, 
    343 U.S. 579
    , 645
    (1952) (Jackson, J., concurring).
    But even giving the widest berth to the Corps’ compelling
    interest in enforcing its grooming and appearance policies
    generally, RFRA requires us to ask the more particularized
    question of whether the Corps “has such an interest in denying
    an exemption” to these specific plaintiffs. Fulton, 141 S. Ct. at
    1881; see also O Centro, 
    546 U.S. at 431
     (requiring courts to
    examine “the asserted harm of granting specific exemptions to
    particular religious claimants”). “Once properly narrowed,”
    Fulton, 141 S. Ct. at 1881, the Marine Corps’ explanation
    founders.     More specifically, Colonel Jeppe’s claimed
    compelling need for inflexible grooming uniformity does not
    stand up against the “system of exceptions” to boot camp
    grooming rules that the Corps has already created and that
    seriously “undermine[]” the Corps’ contention that it “can
    brook no departures” for Plaintiffs. Id. at 1882.
    First, the Marine Corps makes medical exemptions from
    the required shaving of facial hair during boot camp. As the
    Navy Surgeon General’s “senior dermatology medical
    advisor” attests, recruits with pseudofolliculitis barbae
    18
    (“PFB”) develop painful pustules and lesions when shaving.
    Decl. Capt. Josephine Nguyen, MC, USN (“Nguyen Decl.”),
    J.A. 730–732. PFB is a “common” condition “that occurs
    mainly in men of African descent.” Id. ¶ 2, J.A. 730. One
    study by a Navy surgeon suggests that “approximately 45 to
    83% of the African American male population” may suffer
    from PFB. See Jorge Garcia-Zuazaga, Pseudofolliculitis
    barbae: Review and Update on New Treatment Modalities,
    168 MILITARY MED. 561, 561 (2003).
    The Corps has a detailed protocol for excepting recruits
    with PFB from the shaving regimen. Recruits in boot camp
    experiencing a flare-up “typically” receive a “no-shave”
    waiver for four to eight weeks—that is, for one-third to more
    than one-half of their basic training. Nguyen Decl. ¶ 5, J.A.
    732. “[O]nce shaving bumps subside and after clearance by
    medical,” recruits with mild forms of the condition are allowed
    to maintain a beard as long as it is “neatly trimmed[.]” Marine
    Corps Order 6310.1C (“PFB Treatment Protocol”) att. 1 ¶ 1h
    (Oct. 9, 2012), J.A. 260. Recruits with “moderate” cases may
    forgo shaving or clipping altogether and instead use chemical
    products to remove the hair if able. Id. att. 1 ¶ 2, J.A. 261–262.
    If the PFB flare-ups continue with clipping or chemicals, an
    additional four-week exemption from hair removal is
    available—which would then exempt the recruit from
    removing facial hair for virtually the entire boot-camp training
    period. Id. att. 1 ¶ 3a, J.A. 263.
    These medical exemptions directly undermine the Corps’
    claimed compelling interest in subjecting Plaintiffs to “the
    same set of regimented practices” as their peers. Cf. Gov’t Br.
    33. Recruits with PFB routinely will go days or weeks—or
    almost all of boot camp in some cases—without shaving
    alongside fellow recruits. That is because skin has to heal and
    beards have to grow in before clippers or chemicals can even
    19
    be attempted. See PFB Treatment Protocol ¶ 5d, J.A. 258. Yet
    the Marine Corps nowhere argues or even suggests that
    Marines who endure the rigors of recruit training while also
    managing painful PFB come out of boot camp with any less
    commitment to unit cohesion, self-sacrifice, or discipline than
    those who shave daily.
    To be sure, regimentation remains for the recruits in that
    each one must adhere to the Marine Corps’ prescribed
    grooming protocol. But shaving, it turns out, is not an
    indispensable component of that regimen. Instead, the daily
    facial grooming ritual to which Colonel Jeppe refers already
    involves recruits undertaking varied methods to contain their
    facial hair. Most will shave, some will clip, some will apply
    chemicals, and some will do nothing for days or weeks.
    Plaintiffs too would be subject to a regimented daily
    grooming ritual that would obligate them to neatly groom and
    tie their beards on the terms prescribed by the Corps—
    presumably the same terms that would govern their post-boot
    camp grooming obligations. See J.A. 59 (providing that, for
    Jaskirat Singh, when authorized, his “beard must be maintained
    in a neat and conservative manner, as determined by [his]
    squadron or battalion commander[,]” and that it must be no
    more than two inches in length, rolled or tied); J.A. 234 (same
    for Aekash Singh); J.A. 166 (same for Milaap Chahal, except
    that the beard length with tying is limited to ¼ of an inch); see
    also U.S. Navy Bureau of Personnel Instruction
    (BUPERSINST) 1730.11A ¶ 5(d)(4)(c) (March 16, 2020), J.A.
    84 (requiring beards to be “rolled, tied[,] and/or otherwise
    groomed to achieve a length not to exceed 2 inches when
    measured from the bottom of the chin”); Army Directive 2017-
    03, Enclosure at 2–3 (Jan. 3, 2017), J.A. 125–126 (same);
    Department of the Air Force Instruction 52–201 att. 7 (June 23,
    20
    2021) (same); Coast Guard Commandant Instruction
    (COMDTINST) 1000.15 ¶ 11c(4) (Aug. 30, 2021) (same).
    Yet Colonel Jeppe’s declaration fails to explain why
    allowing these three recruits to tightly tie up their beards would
    interfere with the necessary development of a Marine mindset
    during boot camp in a way that growing or clipping beards does
    not.
    Instead, the Corps says that medical exemptions are
    different because recruits with skin conditions are required to
    shave before arriving at recruit training. But that statement
    fails to explain how having a clean-shaven face before
    “ship[ping] to Boot Camp,” Jeppe Decl. ¶ 30a, J.A. 726, is
    indispensable to the formation of a Marine over the course of
    boot camp. Colonel Jeppe’s declaration, in other words, fails
    to connect recruits’ initial appearance upon arrival with those
    day-in and day-out training rituals and regimens for thirteen
    weeks that he says are so crucial to unit cohesion and stripping
    away individuality. See Jeppe Decl. ¶ 20, J.A. 721. After all,
    the central purpose of recruit training is to change that
    individual who shows up on the first day into a fully
    committed, fit, and able Marine ready for the distinct rigors of
    service in the Corps.
    So the Corps’ proffered rationale fails to establish the
    “direct causal link between the restriction imposed and the
    [compelling-interest] injury to be prevented” required by
    RFRA’s strict scrutiny test. Alvarez, 
    567 U.S. at 725
    .
    Of course, the reason for exemption would differ between
    medically exempt and religiously exempt recruits. But that is
    RFRA’s point: Government must, if able, afford religious
    exercise equal stature with other interests that it
    accommodates. See Tandon v. Newsom, 
    141 S. Ct. 1294
    , 1297
    21
    (2021) (per curiam) (rejecting regulations that “treat[ed] some
    comparable secular activities more favorably than at-home
    religious exercise,” without “conclud[ing] that those activities
    pose a lesser risk” of harm); see also Church of the Lukumi
    Babalu Aye, Inc. v. City of Hialeah, 
    508 U.S. 520
    , 547 (1993)
    (“It is established in our strict scrutiny jurisprudence that a law
    cannot be regarded as protecting an interest of the highest order
    when it leaves appreciable damage to that supposedly vital
    interest unprohibited.”) (internal quotation marks and citation
    omitted; formatting modified).
    Second, the Marine Corps exempts female recruits from
    shaving and from cutting their hair altogether. Marine Corps
    Uniform Regulations § 1004 ¶ 7b(1)(a), J.A. 303 (prescribing
    short, medium, and long hairstyles for women). Women are
    allowed instead to wear their hair in several styles. It may be
    short, medium, or long in length; styled with bangs or layers;
    and worn in braids, twists, or locs. Id. § 1004 ¶ 7b(1)(b), J.A.
    303–305. (“Locs” appears as “locks” in the Marine Corps
    Uniform Regulations.) Women Marines may dye their hair if
    it “result[s] in natural colors” that “complement the person’s
    complexion,” and they may wear a natural-looking wig that
    otherwise complies with regulations.               Id. § 1004
    ¶¶ 7b(1)(b)(3), (7), J.A. 305.
    As the Government notes, women’s hairstyles within these
    categories are regulated in various ways. See Gov’t Br. 31–32.
    For instance, bangs cannot be so long that they fall into a
    Marine’s line of sight, and there are limitations on the bulk of
    tied-up hair of two to three inches. Marine Corps Uniform
    Regulations § 1004 ¶¶ 7b(1)(a)(2)–(3), J.A. 303.
    But what matters here is that female recruits plainly do not
    engage in the same daily or weekly grooming rituals as one
    another—let alone as male recruits do. At the same time, they
    22
    still undergo the regimen of daily conforming their hair to
    dictated and detailed standards. See, e.g., Marine Corps
    Uniform Regulations § 1004 ¶ 7b(1)(a)(3), J.A. 303 (“Long
    hair will be neatly and inconspicuously fastened or pinned,
    except that bangs may be worn.”); id. § 1004 ¶ 7b(1)(b), J.A.
    303–304 (requiring hair to “be styled so as not to interfere with
    the proper wear of all uniform headgear” and listing hairstyles
    “not authorized for wear in uniform”); id. § 1004
    ¶ 7b(1)(b)(1)(e), J.A. 304 (“When worn secured, individual
    braids and twists will be small in diameter (no more than 3/8
    inch), and will be tightly interlaced/twisted to present a neat,
    professional military appearance.”).
    Women, in other words, do not engage in a daily facial
    shaving ritual or even a common-among-females hair styling
    regimen. Nonetheless, they emerge from boot camp as full-
    fledged Marines who are as committed to unit cohesion,
    stripped of individuality, and ready to defend the Nation as are
    male recruits.
    Notably, the Marine Corps has been mandated by law to
    integrate its male and female recruit training, and that process
    has already begun. See National Defense Authorization Act of
    2020, Pub. L. No. 116–92 § 565, 
    113 Stat. 1198
    , 1395–1396
    (2019) (codified at note preceding 
    10 U.S.C. § 8431
    ); see also
    Oral Arg. Tr. 59. Yet Colonel Jeppe’s declaration nowhere
    addressed how denying Plaintiffs an exemption to shaving and
    haircut rituals can be a compelling necessity for developing
    Marines when male recruits either already do or soon will train
    alongside recruits that neither shave nor conform to a single
    buzzcut hair style.
    Third, Colonel Jeppe explains that the Corps has a
    compelling interest in minimizing exemptions to its grooming
    policies because the “most important element in the Marine
    23
    Corps’ conduct of expeditionary operations is * * * a team-
    oriented state of mind” at a “whole-of-force level.” Jeppe Decl.
    ¶¶ 25, 31, J.A. 724, 726–727.
    While, as a court, we take as given the Corps’ judgment
    about the need for a singular whole-of-force mindset, that
    claimed interest is troublingly disconnected from the Corps’
    own leadership recruitment process. Specifically, the Marine
    Corps is part of the Navy. 
    10 U.S.C. § 8063
    (a). So many of
    its officers are educated and train at the Naval Academy. Yet
    the Naval Academy accommodates beards, unshorn hair, and
    the wearing of the same Sikh religious articles at issue here.
    Gov’t Br. 27 (“[T]he Navy has adopted more permissive
    accommodations policies at the Academy[.]”); Defs.’ Answer
    at ¶ 218, J.A. 769 (admitting that “midshipmen at the U.S.
    Naval Academy may maintain beards and religious head
    coverings in certain circumstances”).           Notably, those
    accommodations make no apparent exception for the arduous
    initial months of the Naval Academy’s plebe summer.
    Likewise, the other military Academies’ accommodation
    policies do not change during the Army’s and Air Force’s basic
    training for cadets, or the Coast Guard’s swab summer.
    Memorandum from Steven W. Gilland, Brigadier General,
    Commandant of Cadets to Brigade Tactical Officer, U.S. Corps
    of Cadets ¶¶ 2–4, ECF No. 13 Ex. A, Chahal v. Seamands, No.
    17–12656 (E.D. Mich. Aug. 24, 2017) (permitting cadets at
    “the United States Military Academy” to wear “a turban/under-
    turban in a matching camouflage pattern,” among other
    accommodations for cadets with accommodations for “uncut
    beard and uncut hair”); Air Force Cadet Wing Instruction 36–
    3501 ¶ 6.2.1.2.1 (Aug. 12, 2020) (“Cadets may * * *
    grow/wear * * * beards * * * with an approved religious
    accommodation request using the process outlined in [Air
    Force Instruction] 36–2903.”); Coast Guard Commandant
    Instruction (COMDTINST) 1000.15 ¶¶ 4, 11c (Aug. 30, 2021)
    24
    (applying religious accommodation policy to “Coast Guard
    Academy cadets”).
    The Government advises that, after graduating from the
    Naval Academy, cadets who wish to enter the Marine Corps
    must go through a four-week Leatherneck training program and
    then six months at The Basic School. Gov’t Br. 27–28. Yet in
    denying Plaintiffs their accommodations, the Marine Corps
    never addressed the fact that those expeditionary officers might
    be accommodated through their training. See Oral Arg. Tr.
    42:21–25 (Q:         “You’re not aware that [religious
    accommodations] are stripped away, having been granted for
    four years, including summers working with the Marines?” A:
    “Not aware of that, Your Honor.”); see also Gov’t Br. 26
    (“[R]eligious apparel that is not visible or apparent in
    uniform”—like the comb, ceremonial knife, and undershorts
    sought to be worn by Milaap Chahal—“is permitted in some
    instances” during Officer Candidates School.).
    Fourth, the Marine Corps has chosen to moderate its
    grooming requirements when doing so advances recruitment
    interests. Specifically, the Corps permits tattoos anywhere on
    a recruit’s body except for their head, neck, or hands—and
    even that latter restriction is subject to exceptions. Marine
    Corps Bulletin 1020 at 3 (Oct. 29, 2021), J.A. 64 (“Marines or
    applicants with tattoos or brands outside of the authorized areas
    * * * may request an exception to policy to the appropriate
    adjudicating authority,” although they are “not likely to be
    approved.”).
    Yet tattoos are a quintessential expression of individual
    identity. Still, the Corps permits them during boot camp not
    because tattoos comport with the Corps’ interest in stripping
    recruits of individuality, but because “their prevalence in
    25
    society creates a potential problem for recruitment,” and they
    “cannot be readily removed[.]” Jeppe Decl. ¶ 32(a), J.A. 727.
    If the need to develop unit cohesion during recruit training
    can accommodate some external indicia of individuality, then
    whatever line is drawn cannot turn on whether those indicia are
    prevalent in society or instead reflect the faith practice of a
    minority. See Larson v. Valente, 
    456 U.S. 228
    , 245 (1982)
    (“Free exercise thus can be guaranteed only when legislators
    * * * are required to accord to their own religions the very same
    treatment given to small, new, or unpopular denominations.”);
    cf. Railway Exp. Agency v. New York, 
    336 U.S. 106
    , 112 (1949)
    (Jackson, J., concurring) (“The framers of the Constitution
    knew, and we should not forget today, that there is no more
    effective practical guaranty against arbitrary and unreasonable
    government than to require that the principles of law which
    officials would impose upon a minority must be imposed
    generally.”).
    Nor can the Marine Corps tenably rely on the difficulty of
    tattoo removal to justify the differential treatment. Sikhs have
    historically endured persecution, torture, and death rather than
    surrender their faith indicia. See, e.g., A. Walter Dorn &
    Stephen Gucciardi, The Sword & the Turban: Armed Force in
    Sikh Thought, 10 J. MILITARY ETHICS 52, 64–66 (2011). So the
    removal of a religiously commanded article of faith could be
    far more “difficult” for Plaintiffs than the temporary physical
    discomfort of a tattoo’s excision.
    In short, even fully crediting the Marine Corps’
    overarching compelling interests in developing unit cohesion,
    stripping individuality, and building a team-oriented state of
    mind, the Government has not come close to meeting its burden
    of showing “why it has a particular interest” in denying hair,
    beard, and religious article exceptions to these Plaintiffs “while
    26
    making them available to others” in the same or analogous
    form. See Fulton, 141 S. Ct. at 1882. In other words, the Corps
    has not shown, in light of its preexisting exemptions to the
    grooming process—which go largely unexamined by Colonel
    Jeppe—that denying these accommodations would have any
    impact on its claimed interests. See Alvarez, 
    567 U.S. at 725
    ;
    O Centro, 
    546 U.S. at 431
    .
    2
    Plaintiffs’ prospects of success are even greater because the
    Marine Corps has failed to demonstrate that denying Plaintiffs
    the same accommodations during boot camp that they would
    be given during later service in the Corps is the “least restrictive
    means” of advancing its interest in developing unit cohesion
    and a team-oriented mindset. Hobby Lobby, 573 U.S. at 691.
    Specifically, the Marine Corps has not shown that its
    approach is “narrowly tailored” in pursuit of those interests.
    Hobby Lobby, 573 U.S at 719 n.30; see Church of the Lukumi
    Babalu Aye, 
    508 U.S. at 546
    . A government policy is not
    narrowly tailored when it is either overinclusive or
    underinclusive—and on this record, the Corps’ policy is both.
    See Holt, 574 U.S. at 367; see also Church of the Lukumi
    Babalu Aye, 
    508 U.S. at 546
    . The Corps likewise has wholly
    failed to explain how its asserted national security harms
    “would” result just from accommodating these Plaintiffs in a
    manner similar to exemptions already made on a daily basis.
    See O Centro, 
    546 U.S. at 431
     (quoting Yoder, 
    406 U.S. at 236
    ).
    At the outset, the Corps’ claimed inability to depart from
    uniform shaving and haircuts is materially undermined by the
    already noted exemptions for medical beards, women’s
    hairstyles, at least some aspects of officer training, and tattoos.
    That itself is powerful evidence that the Corps’ policy is not
    27
    narrowly tailored. See Holt, 574 U.S. at 367–368 (finding that
    the Government failed to explain “why its grooming policy is
    substantially underinclusive” when it rejected petitioner’s
    request to grow a ½-inch beard as part of his religious
    observance while it permitted ¼-inch beards for medical
    reasons and hair of ½-inch length on heads); see also Church
    of the Lukumi Babalu Aye, 
    508 U.S. at 547
     (“[T]he ordinances
    are underinclusive to a substantial extent with respect to each
    of the interests that respondent has asserted, and it is only
    conduct motivated by religious conviction that bears the weight
    of the governmental restrictions.”); Hobby Lobby, 573 U.S. at
    728.
    In addition, the Marine Corps has provided no evidence
    that it even considered less restrictive alternatives. While the
    Corps need not refute every conceivable option to show its
    policy is the least restrictive means of advancing a compelling
    interest, it must at minimum explain why obvious and available
    alternatives are not workable. Holt, 574 U.S. at 365–367. Even
    when RFRA requires great deference, as it surely does here, the
    Government still must provide “persuasive reasons” for
    rejecting readily at hand alternatives, especially those that have
    been proven to work in analogous circumstances. See id. at
    368–369.
    The Plaintiffs have convincingly shown that the Marine
    Corps has failed to grapple with that aspect of the least-
    restrictive-means requirement. For example, nowhere do the
    Marine Corps’ accommodation denials, Colonel Jeppe’s
    declaration, or the Government’s briefs in this court explain
    why the Corps cannot apply the same or similar
    accommodations that the Army, Navy, Air Force, and Coast
    Guard provide in recruit training, both at boot camp and in the
    Academies.
    28
    The Navy, for example, allows members to seek an
    accommodation to wear unshorn hair and a beard for religious
    reasons, provided that the beard is neatly groomed or tied, and
    it permits Sikhs to retain their other articles of faith. Its
    standards and procedures governing religious accommodations
    provide that sailors may apply to wear a turban, among other
    religious head coverings, and that unless safety requires
    otherwise, a sailor granted such an accommodation is not
    required to wear military headgear on top of their religious
    head covering. A sailor can seek permission to wear unshorn
    hair in a patka or turban and a beard, provided that beards are
    “worn in a neat and conservative manner” and do not exceed
    two inches in length or may be groomed to not exceed two
    inches. Bureau of Navy Personnel Instruction (BUPERSINST)
    1730.11A ¶ 5(d)(4) (March 16, 2020), J.A. 84.2
    Given that the Marine Corps is part of the Department of
    the Navy and designed for “service with the fleet,” 10 U.S.C.
    2
    The Army, Air Force, and Coast Guard have similar policies. The
    Army maintains the same guidelines for beard length and
    appearance. Army Directive 2017–03 Enclosure at 2–3 (Jan. 3,
    2017), J.A. 125–126. In addition, “[a]n accommodated Soldier may
    wear a turban (or under-turban or patka, as appropriate) made of a
    subdued material in a color that closely resembles the headgear for
    an assigned uniform[,]” so long as the head covering is “worn in a
    neat and conservative manner that presents a professional and well-
    groomed appearance.” Id. at 3, J.A. 126. The Air Force may also
    approve accommodations for turbans, beards, and unshorn hair with
    the same guidelines as the other branches. See Religious Freedom in
    the Department of the Air Force, Department of the Air Force
    Instruction (DAFI) 52–201 at 32–33 (June 23, 2021) (template for
    “turban, uncut beard and hair approval memorandum”). The Coast
    Guard also allows waivers of its grooming policy for turbans,
    unshorn hair, and beards if neatly groomed. Military Religious
    Accommodations, Coast Guard Commandant Instruction
    (COMDTINST) 1000.15 §§ 11(c)(4), (6) (Aug. 30, 2021).
    29
    § 8063(a), the Marine Corps’ failure to consider the
    accommodations made by the Navy takes much air out of its
    least-restrictive-means claim. We are left with no explanation
    why accommodations work for sailors but not Marines serving
    on the same ships or at the same bases. Perhaps there is a
    reason. But the Marine Corps has not voiced it at any point
    over the last nearly two years of litigation and has no apparent
    plans to do so. See Defs. Objs. & Resps. Pls.’ 1st Set Interrogs.
    at 2, ECF No. 66–1, Toor v. Berger, No. 22–1004 (D.D.C. Dec.
    12, 2022) (opposing discovery on religious accommodation
    practices “outside of the Marine Corps” because they are “of
    tangential, if any, relevance to the claims at issue in this
    case[.]”).
    That void leaves this court no basis to conclude that
    similar accommodations would be inimical to developing
    excellent and team-oriented Marines. See Holt, 574 U.S. at
    368–369 (“‘While not necessarily controlling, the policies
    followed at other well-run institutions would be relevant to a
    determination of the need for a particular type of restriction.’
    That so many other prisons allow inmates to grow beards while
    ensuring prison safety and security suggests that the
    Department could satisfy its security concerns through a means
    less restrictive than denying petitioner the exemption he
    seeks.”) (quoting Procunier v. Martinez, 
    416 U.S. 396
    , 414
    n.14 (1974)).
    The Marine Corps instead relies on its status as the only
    fully “expeditionary” unit within the military. Jeppe Decl.
    ¶¶ 25, 31, J.A. 723–724, 726–727. Such expeditionary service,
    Colonel Jeppe explains, may require quick responses “to a
    broad variety of crises and conflicts across the full spectrum of
    military operations anywhere in the world.” Jeppe Decl. ¶ 25,
    J.A. 723–724.
    30
    That may well be true. But the expeditionary function of
    Marines after they complete boot camp or the Academy is
    orthogonal to the only issue in this case, which is whether
    accommodations will be provided to recruits in Marine boot
    camp. No one in boot camp is deploying on a military
    expedition.
    To the extent Colonel Jeppe means that rigid grooming
    requirements are required to develop an “expeditionary
    mindset,” Jeppe Decl. ¶¶ 25, 26, 28, J.A. 724–725, that claim
    cannot be reconciled with the exemptions already made for
    other Marine recruits’ beards, hair, and other individual
    physical indicia. More specifically, Colonel Jeppe offers no
    word of explanation as to why accommodating Sikh beards that
    are neatly groomed and tied, or unshorn hair neatly wrapped in
    a patka or turban, would impair the development of the Marine
    expeditionary mindset in a way that beards grown by
    individuals with PFB or unshorn hair worn by women recruits
    or officers has not.
    Colonel Jeppe likewise offers no support for his concern
    that accommodating these Plaintiffs could have a “cumulative
    impact” on the Corps’ “whole-of-force” expeditionary
    mindset, see Jeppe Decl. ¶¶ 10c, 31, J.A. 717, 726, that would
    outstrip the effects of the exemptions already allowed. See O
    Centro, 
    546 U.S. at
    435–436 (rejecting “the classic rejoinder of
    bureaucrats throughout history: If I make an exception for you,
    I’ll have to make one for everybody, so no exceptions”);
    Yellowbear v. Lampert, 
    741 F.3d 48
    , 62 (10th Cir. 2014)
    (Gorsuch, J.) (“It can’t be the case that the speculative
    possibility that one exception conceivably might lead to others
    is always reason enough to reject a request for the first
    exception.”) (emphasis omitted).
    31
    On top of that, the Corps nowhere wrestles with its own
    history of flexible grooming and uniform requirements. The
    Marine Corps has been an “expeditionary” force since its
    creation in 1775. See 3 JOURNALS OF THE CONTINENTAL
    CONGRESS, 1774–1789 at 348 (1904–1937); An Act for the
    establishing and organizing a Marine Corps § 6, 
    1 Stat. 594
    ,
    596 (1798) (“[T]he [M]arine [C]orps established by this act,
    shall, at any time, be liable to do duty in the forts and garrisons
    of the United States, on the sea coast, or any other duty on
    shore, as the President, at his discretion, shall direct.”); Oral
    Arg. Tr. 61:15–19, 61:25–62:07.
    Yet the Corps’ current policy forbidding facial hair has
    been in place only since 1976. MARINE CORPS UNIFORM
    REGULATIONS (1976) §§ 1101.1(a), (b). For at least the first
    150 years of the Corps’ history, including through the
    Revolutionary War and two World Wars, beards were fully
    compatible with the Marine Corps’ mission success and
    expeditionary mindset. General Order, in REGULATIONS FOR
    THE UNIFORM AND DRESS OF THE NAVY AND MARINE CORPS OF
    THE UNITED STATES (1852) (permitting beards if not “worn
    long”); UNIFORM REGULATIONS, U.S. MARINE CORPS § 32
    (1917) (“[A] mustache, or beard and mustache, may be worn at
    discretion.”); UNIFORM REGULATIONS, U.S. MARINE CORPS
    § 32 (1912) (same); see also ROBERT H. RANKIN, UNIFORMS OF
    THE SEA SERVICES 129 (1962) (describing changes in the
    Corps’ uniform hair styles over time, including a “queued”
    ponytail during the early Republic); see generally UNIFORM
    REGULATIONS, U.S. MARINE CORPS (1937) (making no
    mention of facial hair).
    That is not to say that military practices cannot evolve over
    time. They certainly can. But RFRA requires that a claim of
    inflexible necessity not completely ignore past practice. Said
    another way, the Marine Corps’ admission that the grooming
    32
    policy being enforced against Plaintiffs has only been part of
    developing Marine recruits for “decades,” Jeppe Decl. ¶ 27,
    J.A. 724–725, raises least-restrictive-means question marks
    that the Corps, on this record, has left unaddressed and
    seemingly unconsidered.
    Finally, the Plaintiffs have shown that the Corps’ flat
    refusal to permit Plaintiffs’ other articles of faith, even those
    that are invisible to the eye because they are worn under
    clothing or head wear (the comb, ceremonial knife, and
    undershorts), similarly fails narrow tailoring. The Marine
    Corps has not offered a single word of defense for that aspect
    of the decision denying accommodations either in its appellate
    brief or in its earlier opposition to Plaintiffs’ request for an
    injunction pending appeal. Gov’t Br. 14–45; Gov’t Resp. in
    Opp. to Pl. Mot. For Inj. Pending App. 8–22. In addition, the
    other military branches and the Corps’ own regulations have
    long permitted the wearing of discreet religious wristbands and
    other articles of faith during military service. See MARINE
    CORPS UNIFORM REGULATIONS § 1101.4 (1983) (allowing
    “inconspicuous wristwatches, watchbands and rings” while in
    uniform). Such silence does nothing to meet RFRA’s
    demanding burden of least-restrictive-means justification for
    substantial burdens on religious exercise.
    *****
    To sum up, Plaintiffs have demonstrated not just a likely,
    but an overwhelming, prospect of success on the merits of their
    RFRA claim. At a general level, the Government has certainly
    articulated a compelling national security interest in training
    Marine Corps recruits to strip away their individuality and
    adopt a team-oriented mindset committed to the military
    mission and defense of the Nation. But RFRA requires more
    than pointing to interests at such a broad level. Holt, 
    574 U.S. 33
    at 363. The Marine Corps has to show that its substantial
    burdening of these Plaintiffs’ religion furthers that compelling
    interest by the least restrictive means. That is where the Marine
    Corps has come up very short given (1) the series of
    exemptions for unshorn head and facial hair already allowed;
    (2) the absence of any particularized explanation as to why
    regulating Plaintiffs’ maintenance and grooming of their
    beards and hair would interfere with the development of
    Marines’ fitness in a way that other analogous exemptions have
    not; and (3) the failure of the Corps to even consider, let alone
    refute, that less restrictive alternatives would serve the Corps’
    recruit-training interests.
    There may well be ways in which the recruit training needs
    of the Marine Corps differ from those of the other military
    branches, and there no doubt are aspects of the training regimen
    that cannot safely be compromised. But Plaintiffs have
    persuasively shown that, after almost two years of
    administrative and legal proceedings, the Marine Corps has not
    come forward with any justification for denying these
    requested accommodations during boot camp that could meet
    RFRA’s stringent burden. While the Government remains free
    to offer further justifications before the district court, it has
    offered this court no reason to believe that any such
    representations will change the record in a relevant way. See
    Oral Arg. Tr. at 31:14–17 (“The * * * Government won’t
    change its reasons[.]”); Defs. Objs. & Resps. Pls.’ 1st Set
    Interrogs. at 2, ECF No. 66–1, Toor v. Berger, No. 22–1004
    (D.D.C. Dec. 12, 2022) (“[T]he parties agree that the ‘core
    factual issues are not in dispute at this stage of the litigation.’”)
    (quoting Joint R. 26(f) Report & Disc. Plan at 1, ECF No. 54,
    Toor v. Berger, No. 22–1004 (D.D.C. Sept. 21, 2022)).
    Because RFRA claims “should be adjudicated in the same
    manner as constitutionally mandated applications” of the strict
    34
    scrutiny test, we need not address the Plaintiffs’ likelihood of
    success on their First Amendment claim, which would at most
    require the application of the standard that RFRA already
    imposes on the Corps’ denial of accommodations. O Centro,
    
    546 U.S. at 430
    ; see Jarkesy v. S.E.C., 
    803 F.3d 9
    , 25 (D.C.
    Cir. 2015) (“Out of respect for the political branches, courts
    generally avoid ruling on constitutional grounds when
    possible.”) (citing Ashwander v. Tennessee Valley Auth., 
    297 U.S. 288
    , 346–347 (1936) (Brandeis, J., concurring)).
    B
    On this record, the public interest and the balance of
    equitable considerations weigh strongly in favor of granting an
    injunction. The balance of the equities and the public interest
    “merge when, as here, the Government is the opposing party,”
    so we address them together. Karem v. Trump, 
    960 F.3d 656
    ,
    668 (D.C. Cir. 2020) (quoting Nken v. Holder, 
    556 U.S. 418
    ,
    435 (2009)) (formatting modified).
    On the Plaintiffs’ side of the balance is the weighty public
    interest in the free exercise of religion that RFRA protects.
    Though we do not address the Plaintiffs’ likelihood of success
    on their First Amendment claim, when it comes to the balance
    of interests, we can fairly take note of the parallelism between
    RFRA and the First Amendment, which imposes the same strict
    scrutiny test as RFRA on governmental actions that selectively
    exclude religious exercise from exemptions afforded to others
    for secular reasons. See, e.g., O Centro, 
    546 U.S. at
    429–430;
    Church of the Lukumi Babalu Aye, 
    508 U.S. at
    546–547;
    Kaemmerling v. Lappin, 
    553 F.3d 669
    , 677 (D.C. Cir. 2008).
    Indeed, the Marine Corps’ defense against the Plaintiffs’ First
    Amendment–based request for a preliminary injunction simply
    incorporates in one paragraph its insufficient defense under
    RFRA. Gov’t Br. 34–35.
    35
    So when viewed through the lens of RFRA, much like
    under the First Amendment, the Plaintiffs have demonstrated a
    weighty public interest in vindicating their claim to fair
    treatment in the Marine Corps’ exemption process. Cf., e.g.,
    Karem, 960 F.3d at 668 (“[E]nforcement of an unconstitutional
    law is always contrary to the public interest.”) (quoting Gordon
    v. Holder, 
    721 F.3d 638
    , 653 (D.C. Cir. 2013)).
    On the Government’s side of the balance, we accord
    relevant weight to the nature of the requested injunction as one
    that will change the status quo in military training during
    litigation and could grant potentially dispositive relief on a
    central claim in the case because of boot camp’s relatively short
    duration.
    We conclude those interests are outweighed in this case by
    the Plaintiffs’ convincing showing of the Marine Corps’ broad
    failure to demonstrate, at this preliminary stage, a rational
    connection between its asserted training interests and the
    failure to extend to Plaintiffs the same type of accommodations
    it already affords others for secular reasons. The declaration
    from Colonel Jeppe also fails entirely to address whether less
    restrictive means could accommodate both the Corps’ own
    needs and those of Plaintiffs.
    To be sure, Colonel Jeppe’s declaration asserts that
    accommodating the Plaintiffs would imperil the national
    security by interfering with the training of Marines for their
    expeditionary role and the rigors of service in the Corps. Jeppe
    Decl. ¶ 27, J.A. 724–725. Needless to say, protecting the
    national security is an interest of paramount concern. See
    Winter, 
    555 U.S. at
    24–25. And courts are loath to second-
    guess the judgments of the Political Branches in that regard.
    See 
    id. at 24
    .
    36
    But unlike Winter, the “most senior officer[]” in the
    military, 
    555 U.S. at 24
    , to speak on this issue—the
    Commander in Chief—has voiced a profound national interest
    in diversity within the military. See JOSEPH R. BIDEN,
    NATIONAL SECURITY STRATEGY 21 (Oct. 2022); Jim
    Garamone, Biden Showcases the Strength, Excellence of
    American Military Diversity, U.S. DEP’T OF DEFENSE (March
    8,    2021),     https://www.defense.gov/News/News-Stories/
    Article/Article/2529262/biden-showcases-the-strength-excelle
    nce-of-american-military-diversity/ (last visited Dec. 16,
    2022). Even more, three different Presidents have joined with
    four different Congresses over the last 35 years to codify into
    law the imperative that military commanders make military
    service compatible with diverse religious traditions, “including
    Christian, Hindu, Jewish, Muslim, [and] Sikh” faiths. Pub. L.
    No. 114–92 § 528; see 42 U.S.C. § 2000bb–1(b); 
    10 U.S.C. § 774
    ; Pub. L. No. 113–66 §§ 532–533; see also Remarks at a
    Joint Reserve Officer Training Corps Commissioning
    Ceremony, 1 PUB. PAPERS 596 (May 17, 2007) (statement of
    President George W. Bush praising “the great diversity of the
    American people” represented in the Armed Forces).
    In addition, Colonel Jeppe’s superiors within the Marine
    Corps have themselves stressed that “the readiness and mission
    success of our * * * Marine Corps” is “inextricably linked” to
    its diversity. Memorandum for Assistant Secretaries of the
    Navy, General Counsel, Commandant of the Marine Corps,
    and Chief of Naval Operations, Department of the Navy
    Diversity, Equity, and Inclusion Going Forward 1 (Nov. 15,
    2021), J.A. 543; see also JOSEPH R. BIDEN, NATIONAL
    SECURITY STRATEGY 21 (Oct. 2022) (“[P]romoting diversity
    and inclusion” will “strengthen the effectiveness of the
    military.”).
    37
    Importantly, Plaintiffs have shown at this preliminary
    stage that the accommodations they seek will both increase
    religious diversity in the Marine Corps and fully comport with
    military training needs. Colonel Jeppe’s lone declaration does
    not demonstrate otherwise or even address those instructions
    from Presidents and Congresses. Under these unusual
    circumstances, and given the courts’ respect for the Political
    Branches’ expertise in handling military matters, the public
    interest and the balance of equities in this case weigh decisively
    in favor of preliminary relief.
    Finally, while the record establishes that preliminary relief
    is warranted, this decision in no way prejudges the
    Government’s ability going forward to defend its policy on the
    merits before the district court. Sherley, 689 F.3d at 782 (“To
    the extent an appellate court predicts, without making a
    definitive legal conclusion, that the plaintiffs probably or likely
    will or will not succeed on the merits, it cannot be said that the
    court ‘affirmatively decided’ the issue such that it would bind
    an appellate court at a later stage of the litigation.”) (quoting
    Crocker v. Piedmont Aviation, Inc., 
    49 F.3d 735
    , 739 (D.C. Cir.
    1995)).
    C
    Two of the plaintiffs—Jaskirat Singh and Milaap Chahal—
    also have demonstrated that they are currently suffering
    continuing irreparable harm. “The loss of First Amendment
    freedoms, for even minimal periods of time, unquestionably
    constitutes irreparable injury.” Roman Catholic Diocese of
    Brooklyn v. Cuomo, 
    141 S. Ct. 63
    , 67 (2020) (per curiam)
    (quoting Elrod v. Burns, 
    427 U.S. 347
    , 373 (1976) (plurality
    op.)). At least when, as here, the Government has not argued
    that there is any relevant daylight between the RFRA and First
    Amendment analyses, then a comparably irreparable injury
    38
    applies to violations of RFRA. Hobby Lobby Stores v.

    Still, preliminary relief is the rare exception, and even in
    claims of constitutional or RFRA violations, a preliminary
    injunction will issue only if the asserted harm will certainly
    accrue “in the absence of preliminary relief”—that is, before
    the district court can resolve the case on the merits. Winter,

    must be ongoing or “imminen[t].” Chaplaincy of Full Gospel

    Milaap Chahal and Jaskirat Singh have made that showing.
    The Corps recognizes that they are otherwise fully qualified to
    enlist in the Marine Corps, and they would join the Corps
    immediately but for the Corps’ refusal to extend existing hair
    and shaving exemptions to their exercise of faith or to
    accommodate their religious articles. Notice of Supp., att. 1

    29, 2022); 
    id.
     att. 3 ¶ 6. Each day that the Marine Corps refuses
    to let them take the oath of enlistment unless they surrender
    their faith inflicts an irreversible and irreparable harm. They
    are forced daily to choose between their religion and “the
    performance of [the] supreme and noble duty of contributing to
    the defense of the rights and honor of the nation,” Arver v.
    United States, 
    245 U.S. 366
    , 390 (1918), and are subjected to
    the “indignity” of being unable to serve for reasons that, on this
    record, “bear[] no relationship to their ability to perform,” Roe
    v. Shanahan,

    The appropriateness of injunctive relief at this time is less
    clear for Aekash Singh. To be sure, he has the same likelihood
    of success on the merits and the balance of interests equally
    favors him. He also persuasively alleges that the Marine Corps
    already inflicted irreparable harm when he attempted to swear
    into the Corps and was told he could not unless he promised to
    cut his hair and remove his turban. Compl. ¶ 188, J.A. 40. But
    redress for that past injury does not depend on obtaining
    preliminary relief now. As for his present or future intention
    to join the Corps, counsel has advised this court that Aekash
    Singh may have postponed his plans to enlist until at least 2024.
    See Pl. Opening Br. 24; Notice of Supp., att. 2 ¶ 4, ECF No. 60,
    Toor v. Berger, No. 22–1004 (D.D.C. Nov. 29, 2022). Because
    this factual issue bearing on when Aekash Singh now plans to
    enlist was not raised before the district court, we leave it to that
    court on remand to determine whether his injury is currently or
    will be imminently sufficient to warrant the issuance of
    preliminary relief.
    IV
    Plaintiffs have shown both an overwhelming likelihood of
    success on the merits and that the balance of the equities and
    public interest weigh in their favor. Jaskirat Singh and Milaap
    Chahal have also shown ongoing irreparable injury. For those
    reasons, we reverse the district court’s denial of preliminary
    injunctive relief for Jaskirat Singh and Milaap Chahal and
    remand to the district court for the prompt entry of a
    preliminary injunction requiring the Marine Corps to allow
    them to enlist without shaving their heads or beards and while
    bearing those articles of faith that the Government failed to
    argue against on appeal.
    We remand for further consideration of Aekash Singh’s
    request for a preliminary injunction in light of this opinion and

    the declaration recently filed in district court addressing the
    timing of his desired accession into the Marine Corps.
