    SUMMARY*
    Veterans Affairs
    The panel filed an amended opinion affirming in part and
    reversing in part the district court’s judgment and injunction
    entered in an action brought by veterans organizations and
    individuals who were subjects in chemical and biological
    weapons experiments conducted by the United States
    military, seeking declaratory and injunctive relief against
    federal agencies; denied the petition for panel rehearing; and
    denied on behalf of the court the petition for rehearing en
    banc.

    This summary constitutes no part of the opinion of the court. It has
    been prepared by court staff for the convenience of the reader.
    VIETNAM VETERANS OF AMERICA V. CIA                   3
    The panel agreed with the district court that the U.S.
    Army had an ongoing duty under Army Regulation 70-25 to
    provide former test subjects with newly available information
    relating to their health, and that this duty was judicially
    enforceable under § 706(1) of the Administrative Procedure
    Act. The panel held that the district court did not abuse its
    discretion in entering its injunction to enforce that duty.
    The panel also agreed with the district court that the Army
    had an ongoing duty to provide medical care. The panel
    disagreed with the district court’s denial of relief on the
    ground that the Department of Veterans Affairs provided
    medical care that to some degree duplicated the care the
    Army was obligated to provide. The panel held that the
    district court may not, in the absence of mootness,
    categorically deny injunctive relief to former volunteer
    subjects seeking necessary medical care because some former
    subjects may be entitled to receive medical care from another
    government agency. The panel vacated the district court’s
    summary judgment for the government on this claim and
    remanded to the district court.
    Judge Wallace joined the majority in affirming the district
    court’s judgment and injunction compelling the Army to
    comply with Army Regulation 70-25’s clear regulatory
    mandate, but wrote separately in concurrence because he did
    not join the majority’s analysis of regulatory history to
    support its textual analysis. Judge Wallace dissented from
    the majority’s conclusion that Army Regulation 70-25 also
    contained a command that the Army provide medical care to
    former research volunteers. He would affirm the district
    court’s summary judgment against plaintiffs on their claims
    for medical care, but on the alternative ground that their claim
    4        VIETNAM VETERANS OF AMERICA V. CIA
    was not judicially enforceable under § 706(1) of the
    Administrative Procedure Act.

    ORDER
    The opinion filed on June 30, 2015 and published at
    
    791 F.3d 1122
    is hereby amended. The amended opinion is
    filed concurrently with this order.
    With these amendments, Judges Schroeder and W.

    Wallace voted to grant the petition for rehearing. Judge W.
    Fletcher voted to deny the petition for rehearing en banc, and
    Judge Schroeder so recommended.               Judge Wallace
    recommended granting the petition for rehearing en banc.
    The full court was advised of the petition for rehearing en
    banc. A judge requested a vote on whether to rehear the
    VIETNAM VETERANS OF AMERICA V. CIA                 5
    matter en banc, and the matter failed to receive a majority of
    the votes of the nonrecused active judges in favor of en banc
    consideration. Fed. R. App. P. 35.
    The petition for panel rehearing and the petition for
    rehearing en banc are DENIED.
    Future petitions for panel rehearing and petitions for
    rehearing en banc will not be entertained.
    OPINION
    W. FLETCHER, Circuit Judge:
    From the inception of the United States’ chemical
    weapons program during World War I until the mid-1970s,
    the United States military conducted chemical and biological
    weapons experiments on human subjects.             In these
    experiments, tens of thousands of members of the United
    States armed services were intentionally exposed to a range
    of chemical and biological agents.
    Plaintiffs are veterans’ organizations and individuals who
    were subjects in these experiments. They filed an individual
    and class action complaint seeking declaratory and injunctive
    relief against the Department of Defense (“DOD”), the Army,
    the Central Intelligence Agency (“CIA”), and the Department
    of Veterans Affairs (“VA”). The class comprises “[a]ll
    current or former members of the armed forces, who, while
    serving in the armed forces, were test subjects” in these
    experimentation programs. Two of Plaintiffs’ claims,
    brought under § 706(1) of the Administrative Procedure Act
    6        VIETNAM VETERANS OF AMERICA V. CIA
    (“APA”), are at issue in this appeal. Plaintiffs claim, first,
    that the Army has unlawfully failed to notify test subjects of
    new medical and scientific information relating to their health
    as it becomes available. They claim, second, that the Army
    has unlawfully withheld medical care for diseases or
    conditions proximately caused by their exposures during the
    experiments.
    On cross-motions for summary judgment, the district
    court held that Army Regulation 70-25 (“AR 70-25”) imposes
    on the Army an ongoing duty to notify former test subjects of
    relevant new health information as it becomes available. The
    court issued an injunction requiring the Army to comply with
    that duty. The court held, further, that AR 70-25 imposes on
    the Army an ongoing duty to provide medical care, but the
    court declined to compel the Army to provide such care on
    the ground that Plaintiffs could seek medical care from the
    VA.
    We affirm in part and reverse in part. We agree with the
    district court that the Army has an ongoing duty under AR
    70-25 to provide former test subjects with newly available
    information relating to their health, and that this duty is
    judicially enforceable under § 706(1). We also agree with the
    district court that the Army has an ongoing duty to provide
    medical care. However, the district court denied relief on the
    ground that the VA provides medical care that to some degree
    duplicates the care the Army is obligated to provide. We
    disagree with the district court that relief should have been
    denied on this ground.
    VIETNAM VETERANS OF AMERICA V. CIA                   7
    I. Background
    As relevant to this suit, beginning in 1942 the War
    Department (as it was then called) approved the use of human
    subjects in experiments to test the effects of chemical
    weapons. Some experiments tested the effectiveness of
    various chemical agents, while others tested the effectiveness
    of protective clothing and other defenses. By the end of
    World War II, more than 60,000 service members had served
    as experimental subjects in the United States’ chemical
    weapons research program.
    During the World War II-era tests, “soldier volunteers”
    were intentionally exposed to a variety of chemical agents.
    According to a 1993 report by the National Academy of
    Sciences, they were exposed to Lewisite (an arsenic-based
    blister agent) and mustard gas, as well as other “gases such as
    phosgene (a choking agent), hydrogen cyanide and cyanogen
    chloride (blood poisoning agents), and chloroacetophenone
    (tear gas).” A 2006 VA report recounted that these subjects
    “were exposed commonly to acutely toxic levels . . . of agents
    via small drops applied to the arm or to clothing, or in gas
    chambers, sometimes without protective clothing.” “Some
    experiments apparently involved less protected subjects who
    were reported to have experienced severe burns to the genital
    areas, including cases of crusted lesions to the scrotum . . . .
    Documented injuries among experimental subjects . . . [were]
    initially ‘quite high’—one study of accidental injuries
    identified over 1,000 cases of acute mustard agent toxicity
    resulting in eye, ear, nose and throat symptoms . . . over a 2-
    year period.”
    In the 1950s, DOD conducted a new wave of chemical
    weapons research and experimentation, focusing on “agents
    8        VIETNAM VETERANS OF AMERICA V. CIA
    perceived to pose greater threats than sulfur mustard or
    Lewisite,” such as nerve agents and chemicals with “intense
    psychoactive properties.” These experiments were conducted
    over the course of about twenty years, from 1955 to 1975.
    During the course of this research, DOD exposed about 6,700
    experimental human subjects to more than 250 different
    chemical and biological agents.
    Beginning in the 1950s, the Army established policies and
    issued regulations governing the use of human test subjects.
    On February 26, 1953, Secretary of Defense Charles Wilson
    sent a memorandum (“the Wilson Directive”) to the
    Secretaries of the Army, Navy, and Air Force. The Wilson
    Directive set conditions for “the use of human volunteers by
    the Department of Defense in experimental research in the
    fields of atomic, biological and/or chemical warfare.” It
    stated that “[t]he voluntary consent of the human subject is
    absolutely essential,” and instructed that a volunteer subject
    “should have sufficient knowledge and comprehension of the
    elements of the subject matter involved as to enable him to
    make an understanding and enlightened decision” about
    participating.
    On June 30, 1953, Brigadier General John Oakes,
    Secretary of the General Staff of the Army, sent a
    memorandum (“CS:385”) to the Army’s Chief Chemical
    Officer, the Army Surgeon General, and other top Army
    officials, reiterating the policies articulated in the Wilson
    Directive. CS:385 provided that “[a]gents used in research
    must have” several “limiting characteristics,” including
    “[c]ontrollable lethality,” “[n]o serious chronicity
    anticipated,” “[e]ffective therapy available,” and “[a]dequate
    background of animal experimentation.” The memorandum
    provided further, that “[a]s added protection for volunteers,
    VIETNAM VETERANS OF AMERICA V. CIA                 9
    [other] safeguards will be provided,” including that “[a]ll
    apparatus and instruments necessary to deal with any
    emergency situations must be available,” and that “[m]edical
    treatment and hospitalization will be provided for all
    casualties of the experimentation as required.”
    In 1962, the Army promulgated AR 70-25, a regulation
    prescribing policies and procedures to govern the use of
    volunteers in Army research involving human subjects. AR
    70-25 reiterated the policies in the Wilson Directive,
    including the requirement of voluntary consent. The
    regulation provided:
    [The volunteer] will be told as much of the
    nature, duration, and purpose of the
    experiment, the method, and means by which
    it is to be conducted, and the inconveniences
    and hazards to be expected, as will not
    invalidate the results. He will be fully
    informed of the effects upon his health or
    person which may possibly come from his
    participation in the experiment.
    The regulation also provided, in language similar to CS:385,
    that “[a]ll apparatus and instruments necessary to deal with
    likely emergency situations will be available,” “[r]equired
    medical treatment and hospitalization will be provided for all
    casualties,” and “[a] physician approved by The Surgeon
    General will be responsible for the medical care of
    volunteers.” The Army reissued AR 70-25 in 1974 with the
    foregoing language unchanged.
    In 1975, the Army ceased performing large scale
    experiments exposing human subjects to chemical agents. In
    10       VIETNAM VETERANS OF AMERICA V. CIA
    the late 1970s, against a backdrop of mounting public concern
    about the long-term effects of such experiments, Army
    officials exchanged a series of memoranda outlining a
    program for notifying past subjects about the health
    consequences of their participation in the experiments. On
    August 8, 1979, Army General Counsel Jill Wine-Volner
    wrote a memorandum to a number of high-level Army
    officials and to the Army Surgeon General. She wrote that
    the Secretary of the Army
    has concluded that, as a policy matter, some
    type of notification program is necessary.
    Moreover, the legal necessity for a
    notification program is not open to dispute.
    The Department of Justice has concluded that
    another Federal agency ‘may well be held to
    have a legal duty to notify those . . . drug-
    testing subjects whose health [it] has reason to
    believe may still be adversely affected by
    their prior involvement in [the] drug-testing
    program.’
    (Omission and alterations in original.)
    On September 24, 1979, Wine-Volner wrote another
    memorandum, this time to the Director of the Army Staff,
    providing “broad guidance” about “a program to notify
    participants in Army drug or chemical/biological agent
    research programs.” The memorandum provided, inter alia:
    The Army should review all research
    programs, regardless of whether conducted by
    the Army or on behalf of the Army by
    independent contractors, that were initiated to
    VIETNAM VETERANS OF AMERICA V. CIA                 11
    study possible military, rather than medical,
    applications of various drugs and chemical/
    biological agents. If there is reason to believe
    that any participants in such research
    programs face the risk of continuing injury,
    those participants should be notified of their
    participation and the information known today
    concerning the substance they received. This
    notification should be [e]ffected regardless of
    whether the individuals were fully informed
    volunteers at the time the research was
    undertaken.
    On October 25, 1979, Lieutenant General John McGiffert,
    Director of the Army Staff, wrote a memorandum to the
    heads of Army staff agencies, “establish[ing] Army Staff
    responsibilities for review of past Army research involving
    possible military applications of drug or chemical/biological
    agents.” He wrote, “The objective of this effort is to identify
    and notify those research participants who may face the risk
    of continuing injury.” He continued,
    Participants in those projects who are
    considered by medical authority to be subject
    to the possible risk of a continuing injury are
    to be notified. In the event that long-term
    hazards of a substance are not known, The
    Surgeon General (TSG) should continue to
    monitor research developments, and if at
    some future time more information makes it
    necessary to take some action, TSG should
    recommend appropriate action, including
    notification.
    12       VIETNAM VETERANS OF AMERICA V. CIA
    In 1981 and 1986, the Army took two actions relevant to
    the notification program: amending one record system and
    creating another. The first system, the Research and
    Experimental Case Files, as amended in 1981, compiled a
    database about “[v]olunteers (military members, Federal
    civilian employees, state prisoners) who participated in Army
    tests of potential chemical agents and/or antidotes from the
    early 1950’s until the program ended in 1975.” Privacy Act
    of 1974; Amendment to System Notice, 46 Fed. Reg. 60,639,
    60,640 (Dec. 11, 1981). The purposes of the system were
    “(1) to follow up on individuals who voluntarily participated
    in Army chemical/biological agent research projects for the
    purpose of assessing risks/hazards to them, and (2) for
    retrospective medical/scientific evaluation and future
    scientific and legal significance.” 
    Id. The second
    system, the
    Medical Research Volunteer Registry, newly created in 1986,
    was designed to maintain “[r]ecords of military members,
    civilian employees, and non-DOD civilian volunteers
    participating in current and future research sponsored by the
    U.S. Army Medical Research and Development Command.”
    Privacy Act of 1974; New Record System, 51 Fed. Reg.
    23,576, 23,577 (June 30, 1986). One of the stated purposes
    of the second system was “[t]o assure that the U.S. Army
    Medical Research and Development Command (USAMRDC)
    can contact individuals who participated in research
    conducted/sponsored by the Command in order to provide
    them with newly acquired information, which may have an
    impact on their health.” 
    Id. In 1988,
    the Army reissued AR 70-25. Chapter 2–5(j) of
    the reissued regulation provided that the Army Surgeon
    General “will . . . [d]irect medical followup, when
    appropriate, on research subjects to ensure that any long-
    range problems are detected and treated.” Chapter 2–8(c)
    VIETNAM VETERANS OF AMERICA V. CIA                 13
    provided that “commanders will . . . [e]nsure that research
    volunteers are adequately informed concerning the risks
    associated with their participation, and provide them with any
    newly acquired information that may affect their well-being
    when that information becomes available.”
    Chapter 3–2(h) (“subsection (h)”) of the reissued
    regulation specified:
    Duty to warn.         Commanders have an
    obligation to ensure that research volunteers
    are adequately informed concerning the risks
    involved with their participation in research,
    and to provide them with any newly acquired
    information that may affect their well-being
    when that information becomes available.
    The duty to warn exists even after the
    individual volunteer has completed his or her
    participation in research. To accomplish this,
    the MACOM [(Major Army Commands)] or
    agency conducting or sponsoring research
    must establish a system which will permit the
    identification of volunteers who have
    participated in research conducted or
    sponsored by that command or agency, and
    take actions to notify volunteers of newly
    acquired information.
    Chapter 3–1(k) (“subsection (k)”) specified, “Volunteers are
    authorized all necessary medical care for injury or disease
    that is a proximate result of their participation in research.”
    Finally, in what the Army later conceded was a “serious”
    editing error, Appendix F of the reissued regulation provided
    14        VIETNAM VETERANS OF AMERICA V. CIA
    that “[r]esearch involving deliberate exposure of human
    subjects to nuclear weapons effect, to chemical warfare
    agents, or to biological warfare agents” was “exempt from
    this regulation.”
    The Army revised and reissued AR 70-25 two years later.
    This 1990 revision remains in force today. This revision was,
    in all relevant respects but one, the same as the 1988 revision.
    There was, however, one important change — the correction
    of the erroneous exemption from coverage of human subjects
    who had been deliberately exposed to “nuclear weapon
    effect” and to chemical and biological agents. The 1990
    “Summary of Change” specified, “This change is published
    to correct a serious error that occurred during the final editing
    of the current revision. In attempting to respond to guidance
    from the Office of The Judge Advocate General that a
    subparagraph be moved from the text of the regulation to
    appendix F, the wrong sub-paragraph was moved.” Chapter
    1–4(d)(4) of AR 70-25 was changed in 1990 to state
    explicitly, “The guidance in this regulation pertains to . . .
    [r]esearch involving deliberate exposure of human subjects to
    nuclear weapons effect, to chemical warfare agents, or to
    biological warfare agents.”
    In the decades since the termination of biological and
    chemical testing on human subjects, Defendants have
    identified, contacted, and notified some of the former
    subjects. For example, in 1990 DOD contacted 128 veterans
    who had participated in World War II mustard gas testing. In
    2004, DOD identified 6,387 individuals who had been
    exposed to mustard gas or other agents during World War II-
    era experiments. Beginning in March 2005, the VA sent
    letters to the 319 of those individuals for whom it could find
    contact information.
    VIETNAM VETERANS OF AMERICA V. CIA                15
    In 2009, Plaintiffs filed suit against DOD, the Army, the
    CIA, the VA, and a number of individuals in their official
    capacities. The complaint alleged that the Army was
    required, on an ongoing basis, to (1) provide notice to former
    test subjects about their exposures to biological and chemical
    agents and the currently known health effects of those agents,
    and (2) provide medical care to these test subjects for
    diseases or conditions proximately caused by their
    participation in military experiments.
    The district court granted in part and denied in part
    Plaintiffs’ motion for partial summary judgment, and granted
    in part and denied in part Defendants’ cross-motion for
    summary judgment. The court held that the Army has an
    ongoing duty to notify former test subjects about newly
    available medical and scientific information relating to their
    health, and that the Army has not fully complied with that
    duty. The court issued an injunction requiring the Army to
    comply. The court also concluded that the Army has an
    ongoing duty to provide test subjects with medical care, but
    it declined to issue an injunction enforcing compliance with
    that duty on the ground that medical care was available from
    the VA.
    The parties cross-appealed.
    II. Standard of Review
    We review a district court’s summary judgment de novo.
    Or. Natural Res. Council v. Allen, 
    476 F.3d 1031
    , 1036 (9th
    Cir. 2007). A permanent injunction “‘involves factual, legal,
    and discretionary components,’” so we “review a decision to
    grant such relief under several different standards.” Momot
    v. Mastro, 
    652 F.3d 982
    , 986 (9th Cir. 2011) (quoting Walters
    16        VIETNAM VETERANS OF AMERICA V. CIA
    v. Reno, 
    145 F.3d 1032
    , 1047 (9th Cir. 1998)). We review
    legal conclusions underlying the summary judgment de novo,
    factual findings for clear error, and the scope of the injunction
    for abuse of discretion. 
    Id. III. Discussion
    Section 706(1) of the APA provides that a court “shall
    compel agency action unlawfully withheld or unreasonably
    delayed.” 5 U.S.C. § 706(1). A court can compel agency
    action under this section only if there is “a specific,
    unequivocal command” placed on the agency to take a
    “discrete agency action,” and the agency has failed to take
    that action. Norton v. S. Utah Wilderness Alliance (SUWA),
    
    542 U.S. 55
    , 63–64 (2004) (citation omitted). The agency
    action must be pursuant to a legal obligation “so clearly set
    forth that it could traditionally have been enforced through a
    writ of mandamus.” Hells Canyon Pres. Council v. U.S.
    Forest Serv., 
    593 F.3d 923
    , 932 (9th Cir. 2010). Plaintiffs
    argue that AR 70-25 unequivocally commands the Army to
    provide former test subjects with current information about
    their health, and to provide medical care for harm and
    diseases caused by the experiments. We agree.
    A. Duty to Warn
    We conclude that Chapter 3–2(h) of AR 70-25
    (“subsection (h)”), as promulgated in 1988 and again in 1990,
    requires the Army to provide former test subjects with “newly
    acquired information” regarding their health as that
    information becomes available. We agree with the district
    court that this “duty to warn” applies not only to future
    human subjects, but also to test subjects who participated in
    experiments predating the regulation. We hold, further, that
    VIETNAM VETERANS OF AMERICA V. CIA                17
    the district court did not abuse its discretion in issuing an
    injunction enforcing this duty.
    1. Duty to Warn Under AR 70-25
    AR 70-25 requires the Army to warn volunteers of the
    risks of participating in the experiments, and to provide them
    with new information “that may affect their well-being” as it
    becomes available. Subsection (h) of AR 70-25 provides:
    Duty to warn.         Commanders have an
    obligation to ensure that research volunteers
    are adequately informed concerning the risks
    involved with their participation in research,
    and to provide them with any newly acquired
    information that may affect their well-being
    when that information becomes available.
    The duty to warn exists even after the
    individual volunteer has completed his or her
    participation in research. To accomplish this,
    the MACOM [(Major Army Commands)] or
    agency conducting or sponsoring research
    must establish a system which will permit the
    identification of volunteers who have
    participated in research conducted or
    sponsored by that command or agency, and
    take actions to notify volunteers of newly
    acquired information.
    Subsection (h) was added to AR 70-25 in 1988. The
    Army contends in this litigation that Section (h) has merely
    prospective effect, applying only to human subjects on whom
    experiments were performed after 1988. We disagree.
    18       VIETNAM VETERANS OF AMERICA V. CIA
    The text of subsection (h) makes clear that the duty to
    provide notice applies not only to possible future human test
    subjects but also to former test subjects. There is nothing in
    the text that limits the application of subsection (h) to those
    who volunteered in experiments after the promulgation of the
    regulation in 1998. Indeed, subsection (h) specifically
    requires Army commanders to identify the volunteers “who
    have participated in research conducted or sponsored by that
    command or agency, and take actions to notify volunteers of
    newly acquired information.” (Emphasis added.) Similarly,
    subsection (h) provides that “[t]he duty to warn exists even
    after the individual volunteer has completed his or her
    participation in research.”
    The Army’s revision of AR 70-25 in 1990 makes even
    more compelling this reading of subsection (h). The 1990
    version retains the provision of the 1988 regulation that
    requires notice to human subjects. But the Army made an
    important change in 1990 in stating explicitly that the notice
    requirement under AR 70-25 applies to “[r]esearch involving
    deliberate exposure of human subjects to nuclear weapons
    effect, to chemical warfare agents, or to biological warfare
    agents.” Chapter 1–4(d)(4). The 1990 revision would have
    made little sense if the notice requirement applied only
    prospectively. The only subjects to whom Chapter 1–4(d)(4)
    could apply are those who had previously been part of Army
    experiments. As the district court stated, “Because the Army
    did not [in 1988 or 1990] — and does not — engage in such
    ongoing testing, there would have been no reason to add this
    language to AR 70-25 in 1990 if the regulation did not
    encompass those who had already become such test subjects.”
    This reading of AR 70-25 is consistent with the internal
    agency discussions in the years leading up to the 1988 and
    VIETNAM VETERANS OF AMERICA V. CIA                  19
    1990 revisions of the regulation. Army memoranda
    discussing proposed notification programs all recognized an
    obligation to warn individuals who had been subjects in past
    research and testing about the potential long-term health
    risks, as well as to provide additional information about those
    risks when such information became available. For example,
    Army General Counsel Jill Wine-Volner wrote in her August
    1979 memorandum that “the legal necessity for a notification
    program is not open to dispute.” That led Wine-Volner to
    write a second memorandum in September 1979 stating that
    “[i]f there is reason to believe that any participants in [the
    biological and chemical weapons testing] programs face the
    risk of continuing injury, those participants should be notified
    of their participation and the information known today
    concerning the substance they received.” She wrote, further,
    “This notification should be [e]ffected regardless of whether
    the individuals were fully informed volunteers at the time the
    research was undertaken.”
    This reading of subsection (h) is also consistent with the
    amending and creating of databases in 1981 and 1986. As we
    describe above, in 1981 the Army amended a database that
    included members of the military who had previously
    volunteered for human testing in order “to follow up on
    individuals who voluntarily participated in Army
    chemical/biological agent research projects for the purpose of
    assessing risks/hazards to them.” Privacy Act of 1974;
    Amendment to System Notice, 46 Fed. Reg. 60,639, 60,640
    (Dec. 11, 1981). Then, in 1986, the Army created a new
    database that included members of the military “participating
    in current and future research” in order to “contact
    individuals who participated” in such research in order to
    provide them with “newly acquired information, which may
    have an impact on their health.” Privacy Act of 1974; New
    20       VIETNAM VETERANS OF AMERICA V. CIA
    Record System, 51 Fed. Reg. 23,576, 23,577 (June 30, 1986).
    The Army clearly anticipated using these databases to provide
    ongoing medical health information to the volunteers who
    had participated in the Army’s chemical and biological
    research experiments. Subsection (h) was first promulgated
    in 1988, seven years after the amendment of the first of the
    databases and two years after the creation of the other. In
    other words, subsection (h) was promulgated only after the
    Army had already concluded it had a duty to provide ongoing
    medical care notifications, even to past participants.
    Despite the foregoing, the government contends that
    subsection (h) applies only to human subjects upon whom
    experiments were performed after 1988. They contend that
    subsection (h) is ambiguous and that under Auer v. Robbins,
    
    519 U.S. 452
    (1997), we must defer to the interpretation that
    the Army has proposed during this litigation. We find no
    ambiguity in the text of subsection (h). But even if
    subsection (h) were ambiguous, Auer deference is
    inappropriate.
    Under Auer, “[a]n administrative rule may receive
    substantial deference if it interprets the issuing agency’s own
    ambiguous regulation.” Gonzales v. Oregon, 
    546 U.S. 243
    ,
    255 (2006). Auer deference is not warranted in all
    circumstances. Deference is not warranted “when there is
    reason to suspect that the agency’s interpretation ‘does not
    reflect the agency’s fair and considered judgment on the
    matter in question.’” Christopher v. SmithKline Beecham
    Corp., 
    132 S. Ct. 2156
    , 2166 (2012) (quoting 
    Auer, 519 U.S. at 462
    ). “This might occur when . . . it appears that the
    interpretation is nothing more than a ‘convenient litigating
    position,’” 
    id. (quoting Bowen
    v. Georgetown Univ. Hospital,
    
    488 U.S. 204
    , 213 (1988)), or a “‘post hoc rationalizatio[n]’
    VIETNAM VETERANS OF AMERICA V. CIA                  21
    advanced by an agency seeking to defend past agency action
    against attack,” id. (quoting 
    Auer, 519 U.S. at 462
    ) (emphasis
    and alteration in original).
    The government’s proposed interpretation of subsection
    (h) is a “convenient litigating position” that does not warrant
    Auer deference. The government acknowledges in its
    briefing to us that no court has previously had occasion to
    construe the notice provision of AR 70-25, and it points to no
    prior interpretation of this provision by the Army, in litigation
    or otherwise. Indeed, the district court noted that the Army
    admitted that it “developed [its] interpretation only in the
    context of this litigation.”
    We do not believe that the interpretation of the notice
    provision of AR 70-25 that the government now advances is
    the “agency’s fair and considered judgment on the matter in
    question.” 
    Auer, 519 U.S. at 462
    . In the district court, the
    government supported its interpretation of AR 70-25 by
    relying on the testimony of Dr. Michael Kilpatrick, Director
    of Strategic Communications for the Office of the Under
    Secretary of Defense for Health Affairs. However, we have
    reason to doubt Dr. Kilpatrick’s analysis. As the district court
    observed, “Notably, the agency representative upon whose
    interpretation Defendants rely was mistaken about the date on
    which the operative parts of the regulation were amended,
    suggesting that he did not have a clear understanding of the
    context in which these changes were made.”
    The text of AR 70-25 requires the Army to provide
    ongoing notice to volunteers who “have participated” in the
    Army’s testing programs. We conclude that this duty applies
    to human subjects in the pre-1990 experiments.
    22        VIETNAM VETERANS OF AMERICA V. CIA
    2. Enforceability Under § 706(1)
    Even though AR 70-25 imposes a duty on the Army to
    provide notice to prior test subjects of information regarding
    their well-being, we can enforce that duty only if the text of
    the regulation is a “specific, unequivocal command” to take
    “discrete agency action.” 
    SUWA, 542 U.S. at 63
    –64 (citation
    omitted). The duty to warn contained in subsection (h) is
    such a command.
    We recognize that § 706(1) poses an obstacle for parties
    seeking to compel agency action. In SUWA, the Court
    explained that parties are entitled to relief under § 706(1)
    only if the agency “failed to take a discrete agency action that
    it is required to take,” 
    id. at 64,
    such as “the failure to
    promulgate a rule or take some decision by a statutory
    deadline,” 
    id. at 63.
    The plaintiff in that case, the Southern
    Utah Wilderness Alliance, alleged that the Bureau of Land
    Management (“BLM”) had failed to manage wilderness study
    areas “in a manner so as not to impair the suitability of such
    areas for preservation as wilderness,” 
    id. at 65
    (quoting 43
    U.S.C. § 1782(c)), and that BLM had failed to “manage the
    public lands . . . in accordance with the land use plans,” 
    id. at 67
    (quoting 43 U.S.C. § 1732(a)). The Court held that the
    failures to meet these statutory obligations were “[g]eneral
    deficiencies in compliance” rather than failures to comply
    with commands to perform discrete actions. 
    Id. at 66.
    Therefore, these obligations “lack[ed] the specificity requisite
    for agency action.” 
    Id. “It is
    clear that section 706(1) applies to the situation
    where a federal agency refuses to act in disregard of its legal
    duty to act.” Equal Employment Opportunity Comm’n v.
    Liberty Loan Corp., 
    584 F.2d 853
    , 856 (8th Cir. 1978).
    VIETNAM VETERANS OF AMERICA V. CIA                 23
    Unlike the plaintiffs in SUWA, Plaintiffs have alleged both a
    legal duty to perform a discrete agency action and a failure to
    perform that action. They assert that the Army has an
    ongoing “duty to warn” under subsection (h) of AR 70-25 and
    that the Army has refused to perform that duty.
    The precise efforts the Army must take to identify human
    subjects in past experiments, and the precise content of the
    notice to those subjects who have been identified, necessarily
    entail some discretionary judgment. But discretion in the
    manner in which the duty may be carried out does not mean
    that the Army does not have a duty to perform a “discrete
    action” within the meaning of § 706(a) and SUWA. See
    
    SUWA, 542 U.S. at 65
    (“[W]hen an agency is compelled by
    law to act . . . but the manner of its action is left to the
    agency’s discretion, a court can compel the agency to act, but
    has no power to specify what the action must be.”);
    Firebaugh Canal Co. v. United States, 
    203 F.3d 568
    , 578 (9th
    Cir. 2000) (“Although the district court can compel the
    Department of Interior to provide drainage service as
    mandated by the San Luis Act, the district court cannot
    eliminate agency discretion as to how it satisfies the drainage
    requirement.”).
    3. The District Court’s Injunction
    The government argues that the district court’s injunction
    is improper in its scope and duration. We disagree.
    Under the district court’s injunction, the Army must
    provide
    individuals who, while serving in the armed
    forces, were test subjects in any testing
    24       VIETNAM VETERANS OF AMERICA V. CIA
    program in which humans were exposed to a
    chemical or biological substance for the
    purpose of studying or observing the effects
    of such exposure (that was sponsored,
    overseen, directed, funded, and/or conducted
    by the Department of the Army) . . . with
    newly acquired information that may affect
    their well-being that it has learned since its
    original notification, now and in the future as
    it becomes available[.]
    Specifically, the injunction directs the Army to provide to
    members of the class any information that may affect their
    well-being that has been acquired by the Army and/or its
    agents since June 30, 2006, or will be acquired in the future.
    The injunction directs the Army to file with the court a report
    “describing the efforts it has undertaken to locate the Newly
    Acquired Information,” “confirming whether Newly
    Acquired Information has been found and describing
    generally its nature,” “explaining the plan it has in its
    discretion developed for transmitting Newly Acquired
    Information to the class members entitled to notification,”
    “committing to transmit the Newly Acquired Information”
    within 120 days of the entry of the injunction, and “outlining
    the plan and policies it has in its discretion developed for
    (i) periodically collecting and transmitting Newly Acquired
    Information that becomes available to it after the Entry Date
    and (ii) providing any necessary update reports to the Court
    regarding such future efforts.”
    We hold that the injunction is appropriately tailored to
    direct the Army to carry out its duty to warn, and that the
    district court acted within its discretion. In requiring the
    Army to tell former test subjects about “newly acquired
    VIETNAM VETERANS OF AMERICA V. CIA                 25
    information that may affect their well-being,” the injunction
    reiterates the plain language of AR 70-25’s duty to warn. As
    subsection (h) stated, “Commanders have an obligation to
    ensure that research volunteers are adequately informed
    concerning the risks involved with their participation in
    research, and to provide them with any newly acquired
    information that may affect their well-being when that
    information becomes available.”
    The injunction expressly preserves the Army’s ability to
    act “in its discretion” to develop the appropriate policies in
    order to carry out that duty. It does not prescribe particular
    policies that the Army should follow. It does not even
    specify the means by which the Army must give that notice.
    In this respect, the injunction does not amount to
    programmatic oversight or “judicial entanglement in abstract
    policy disagreements which courts lack both expertise and
    information to solve.” 
    SUWA, 542 U.S. at 66
    . The injunction
    simply directs the Army to fulfill its duty under subsection
    (h).
    B. Duty to Provide Medical Care
    Chapter 3–1(k) of AR 70-25 (“subsection (k)”) provides,
    “Volunteers are authorized all necessary medical care for
    injury or disease that is a proximate result of their
    participation in research.” Plaintiffs seek an injunction that
    would require the Army to provide that care. The parties
    agree that the government does not currently provide medical
    care to former test subjects “in the absence of those
    [individuals] being retirees of the military, medical retirees,
    reservists or active duty military.”
    26       VIETNAM VETERANS OF AMERICA V. CIA
    We conclude that subsection (k), as promulgated in 1988
    and 1990, requires the Army to provide former test subjects
    with medical care for any injuries or diseases that were
    proximately caused by Army experiments in which they
    participated. The fact that the VA provides medical care to
    some former test subjects, for reasons independent of AR 70-
    25, does not relieve the Army of its duty under that
    subsection.
    1. Duty to Provide Care Under AR 70-25
    The text of subsection (k) compels the conclusion that the
    Army must provide care to former test subjects. It provides
    that “[v]olunteers are authorized all necessary medical care”
    for any injuries or diseases that are the proximate result of
    their participation in Army experiments. In its brief to this
    court, the government concedes that subsection (k) requires
    the Army to provide medical care to research volunteers. It
    contends, however, that the duty to provide medical care is
    time-limited, such that the duty exists only during the
    duration of the actual experiment. We disagree that
    subsection (k) contains this time limitation.
    Subsection (k) uses the word “authorized” in describing
    the duty of the Army — “[v]olunteers are authorized all
    necessary medical care.” (Emphasis added.) The natural
    reading of the word “authorized” is that the volunteers are
    entitled to receive the “necessary medical care” specified in
    the subsection. To take a familiar example, when a collective
    bargaining agreement says that an employee is authorized a
    certain amount of sick leave, the employee is entitled to that
    leave. She must show that she is actually sick — just as test
    subjects must show they suffer from diseases that are a
    proximate result of their participation in government
    VIETNAM VETERANS OF AMERICA V. CIA                   27
    experiments — but if she can do so, she is entitled to take
    time off for sick leave. The meaning of “authorized” is no
    different here.
    The government, agreeing with this reading of the word
    “authorized,” concedes in its brief to us that the Army has a
    duty under subsection (k) to provide necessary medical care.
    However, the government contends that the Army’s duty to
    provide medical care ends as soon as the experiment ends. It
    argues in its brief that “the early versions of AR 70-25 make
    clear that the only medical care contemplated under that
    regulation was care during the pendency of the relevant
    testing program itself. Nothing in any of the later versions of
    AR 70-25 expands the limited scope of medical care available
    beyond the period that an individual is participating in a
    specific experiment.” We disagree.
    There is nothing in the text of the current version of AR
    70-25, first promulgated in 1988, that supports a conclusion
    that the Army has a duty to provide medical care, but that the
    duty ceases as soon as the experiment ends. The
    government’s argument is inconsistent with the plain text of
    subsection (k), which states, “Volunteers are authorized all
    necessary medical care for injury or disease that is a
    proximate result of their participation in research.”
    (Emphasis added.) There is nothing in this language to
    suggest that “all” means anything other than “all.” Nor is
    there anything in this language that states or even suggests a
    temporal restriction on volunteers’ entitlement to receive
    medical care. Not only is the government’s argument
    inconsistent with the text, but it also makes little sense. If the
    government is right, volunteers were entitled to medical care
    if they became sick during the actual experiment, but not if
    28       VIETNAM VETERANS OF AMERICA V. CIA
    they fell sick as a result of the experiment the day after it
    ended.
    In sum, we agree with the government that subsection (k)
    requires the Army to provide medical care to all of those
    authorized to receive it. However, we disagree as to the
    period during which the care must be provided. The temporal
    limitation for which the government argues cannot be found
    in the text of subsection (k). Instead, the text compels the
    conclusion that the only limitation is causal. We hold, as did
    the district court, that “AR 70-25 entitles [Plaintiffs] to
    medical care for disabilities, injuries or illnesses caused by
    their participation in government experiments,” not only
    during the course of the experiment but also after the
    experiment has ended.
    2. Injunction to Provide Medical Care
    Section 706(1) of the APA provides that a reviewing
    court “shall . . . compel agency action unlawfully withheld.”
    The word “shall” requires a court to compel agency action
    when, as here, there is a “specific, unequivocal command”
    that the agency must act. 
    SUWA, 542 U.S. at 63
    –64 (citation
    omitted). “The term ‘shall’ is usually regarded as making a
    provision mandatory, and the rules of statutory construction
    presume that the term is used in its ordinary sense unless
    there is clear evidence to the contrary.” Firebaugh Canal
    
    Co., 203 F.3d at 573
    –74; cf. United States v. Monsanto,
    
    491 U.S. 600
    , 607 (1989) (finding that “Congress could not
    have chosen stronger words to express its intent that
    forfeiture be mandatory” than to state that a court “shall”
    order forfeiture).
    VIETNAM VETERANS OF AMERICA V. CIA                29
    We recognize that the operation of § 706(1) is restricted
    to discrete actions that are unequivocally compelled by
    statute or regulation. Courts are not permitted under § 706(1)
    to enter “general orders compelling compliance with broad
    statutory mandates.” 
    SUWA, 542 U.S. at 66
    . In its petition
    for rehearing and rehearing en banc, the government argues
    for the first time that an injunction ordering the Army to
    comply with its duty under subsection (k) is inconsistent with
    § 706(1) because such an injunction would require a “broad
    restructuring of Army programs and operations.” The
    government substantially exaggerates the impact of an
    injunction requiring the Army to provide medical care to
    human test subjects who were harmed by DOD experiments.
    Between 1955 and 1975, DOD exposed about 6,700
    human subjects to chemical and biological agents. DOD has
    since terminated these programs. The group of plaintiffs
    therefore cannot expand, and some of these 6,700 veterans
    have undoubtedly died. DOD also exposed numerous human
    subjects to chemical agents during World War II. We cannot
    determine from the record in this case how many of these
    subjects are still living, but the number cannot be large. In
    fact, as of 2005, the Army had identified contact information
    for only 319 World War II human test subjects. Requiring
    the provision of medical care to this limited population would
    hardly require a “broad restructuring of Army programs and
    operations.” Instead, the Army would be required to provide
    medical care to a relatively small group of living veterans
    who were injured as a proximate result of the government’s
    conduct. This is a discrete action specifically mandated by
    subsection (k) of AR 70-25, for which judicial enforcement
    pursuant to § 706(1) is required.
    30        VIETNAM VETERANS OF AMERICA V. CIA
    The district court concluded that the Army is required
    under subsection (k) to provide necessary medical care on an
    ongoing basis, but held that an injunction was unnecessary,
    given the availability of medical care from the VA. The court
    explained that it would “not enjoin one government agency
    to provide health care when another agency has been
    congressionally mandated to do so.” Notably, however, the
    district court did not hold that the availability of medical care
    from the VA rendered Plaintiffs’ request for an injunction
    moot. Nor does the government argue to us that the
    availability of medical care from the VA renders the
    Plaintiffs’ request moot. We can readily see why it does not
    make such an argument, for there is nothing in the record
    upon which to base a conclusion that the medical care
    available from the VA would be equal in scope and quality to
    the medical care that Plaintiffs claim is owed to them by the
    Army. Indeed, the government admitted in the district court
    that it does not provide medical care to former test subjects
    “in the absence of those [former subjects] being retirees of
    the military, medical retirees, reservists or active duty
    military.” In the absence of mootness, we cannot agree that
    the Army’s duty to provide care is excused by the availability
    of medical care from another government agency, even if that
    care that would overlap to some degree and in some manner
    with the care that the Army is required to provide.
    We hold that the district court may not, in the absence of
    mootness, categorically deny injunctive relief to former
    volunteer subjects seeking necessary medical care because
    some former subjects may be entitled to receive medical care
    from another government agency. Given the present posture
    of the case, however, we do not address whether and in what
    manner the district court might nonetheless take the VA’s
    VIETNAM VETERANS OF AMERICA V. CIA                 31
    provision of medical care into account in formulating an
    injunction on remand.
    Conclusion
    We hold that Chapter 3–2(h) of AR 70-25 imposes a duty
    on the Army to provide all former test subjects with newly
    acquired information that may affect their well-being, and
    that this duty is judicially enforceable under § 706(1). We
    hold that the district court did not abuse its discretion in
    entering its injunction to enforce that duty. We hold, further,
    that the district court was right to find that Chapter 3–1(k)
    imposes a duty to provide medical care. The district court
    should not, however, have declined to compel the provision
    of medical care on the ground that another agency was
    providing similar care to some former test subjects. We
    therefore vacate the district court’s summary judgment for the
    government on this claim and remand to the district court.
    AFFIRMED in part, REVERSED and REMANDED in
    part.
    WALLACE, Circuit Judge, concurring in part and dissenting
    in part:
    I agree that the text of AR 70-25 unequivocally
    commands the Army to provide certain newly acquired
    information to all former research volunteers when that
    information becomes available. Because the Army has
    “unlawfully withheld” agency action by denying that it owes
    this duty to certain past volunteers, I join the majority in
    affirming the district court’s judgment and injunction
    32        VIETNAM VETERANS OF AMERICA V. CIA
    compelling the Army to comply with AR 70-25’s clear
    regulatory mandate. See 5 U.S.C. § 706(1). I write separately
    in concurrence on this point only because I do not join the
    majority’s analysis of regulatory history to support its textual
    analysis.
    I dissent, however, from the majority’s conclusion that
    AR70-25 also contains a “specific, unequivocal command”
    that the Army provide medical care to former research
    volunteers. I would affirm the district court’s decision to
    grant summary judgment against Plaintiffs on their claims for
    medical care, but on the alternative ground that their claim is
    not judicially enforceable under section 706(1) of the
    Administrative Procedure Act (APA).

    “Section 706(1) of the APA . . . serves important interests,
    but [it] does not give us license to ‘compel agency action’
    whenever the agency is withholding or delaying an action we
    think it should take.” Hells Canyon Pres. Council v. U.S.
    Forest Serv., 
    593 F.3d 923
    , 932 (9th Cir. 2010). Rather, our
    authority to “compel agency action” is “carefully
    circumscribed to situations where an agency has ignored a
    specific . . . command,” 
    id., that is
    located in a federal statute
    or “agency regulation[] that ha[s] the force of law,” Norton v.
    S. Utah Wilderness Alliance (SUWA), 
    542 U.S. 55
    , 65 (2004).
    Moreover, the “purportedly withheld action must not only be
    ‘discrete,’” Hells 
    Canyon, 593 F.3d at 932
    , meaning that it
    must be a “precise, definite act,” 
    SUWA, 542 U.S. at 63
    , “but
    also ‘legally 
    required,’” 593 F.3d at 932
    , meaning that the
    text of the statute or regulation contains an “unequivocal
    command” about which an official has “no discretion
    
    whatever,” 542 U.S. at 63
    (internal quotation marks omitted),
    VIETNAM VETERANS OF AMERICA V. CIA                  33
    such that the duty “could traditionally have been enforced
    through a writ of mandamus.” Hells 
    Canyon, 593 F.3d at 932
    .
    A.
    Our analysis must focus exclusively on the text of the
    relevant statutes or regulations to determine whether this
    standard is satisfied. This purely textual approach, amounting
    to a “clear-statement rule,” is not unique to the section 706(1)
    context. It is indispensable whenever a statute requires us to
    determine whether a particular text obligates agency actors to
    assume a specific duty or to perform a discrete act.
    Like an action brought under section 706(1) of the APA,
    for example, a citizen suit may be brought under section
    505(a)(2) of the Clean Water Act only where plaintiffs
    “allege[] a failure of the [EPA] Administrator to perform any
    act or duty under this chapter which is not discretionary with
    the Administrator.” 33 U.S.C. § 1365(a)(2). If plaintiffs are
    to succeed in their citizen suit against the Administrator, we
    have held that “the nondiscretionary nature of the duty must
    be clear-cut—that is, readily ascertainable from the statute
    allegedly giving rise to the duty.” WildEarth Guardians v.
    McCarthy, 
    772 F.3d 1179
    , 1182 (9th Cir. 2014). In other
    words, “[w]e must be able to identify a ‘specific, unequivocal
    command’ from the text of the statute at issue using
    traditional tools of statutory interpretation; it’s not enough
    that such a command could be teased out ‘from an
    amalgamation of disputed statutory provisions and legislative
    history coupled with the [agency’s] own earlier
    interpretation.’” 
    Id. (emphasis added),
    quoting Our
    Children’s Earth Found. v. E.P.A., 
    527 F.3d 842
    , 851 (9th
    Cir. 2008) (stating that plaintiffs must “point to a
    nondiscretionary duty that is readily-ascertainable and not
    34        VIETNAM VETERANS OF AMERICA V. CIA
    only [] the product of a set of inferences based on the overall
    statutory scheme” (alteration in original) (internal quotation
    marks omitted)).
    B.
    Because our inquiry under section 706(1) is necessarily
    limited to whether the text of the relevant Army regulations
    states a specific, unequivocal command to take discrete
    agency action, I cannot join the majority’s perusal of
    “internal agency discussions in the years leading up to the
    1988 and 1990 revisions of [AR 70-25],” nor its discussion of
    the Army’s creation of volunteer databases in 1981 and 1986.
    The majority includes these historical observations because
    it believes they support our reading of AR 70-25. They do, of
    course, but that is irrelevant. Our job is to determine only
    whether a statute or regulation itself objectively creates a
    mandatory duty. As we have previously held, it is
    inappropriate “for us to divine a ‘specific, unequivocal
    command,’ from an amalgamation of disputed statutory
    provisions and legislative history coupled with the [agency’s]
    own earlier interpretation.” Our Children’s Earth 
    Found., 527 F.3d at 851
    , quoting 
    SUWA, 542 U.S. at 63
    . To be sure,
    the majority does not rely exclusively—or even chiefly—on
    non-textual sources in concluding that the Army has an
    unequivocal duty to warn. But by including a discussion of
    regulatory history and historical facts in support of its textual
    analysis, the majority improperly suggests that these extra-
    textual sources and observations have some bearing on
    whether we are authorized to compel unlawfully withheld
    agency action under section 706(1). I write separately to
    dispel any doubt: they do not. I thus join in the result but not
    that part of the majority’s analysis.

    II.
    I dissent from the majority’s conclusion that AR 70-25
    creates an unequivocal duty for the Army, enforceable under
    section 706(1), to provide medical care to former research
    volunteers. As stated above, the Supreme Court’s standard
    under section 706(1) for compelling agency action is
    demanding. See 
    SUWA, 542 U.S. at 63
    . We ourselves have
    explained that we can compel agency action only when the
    legal obligation is “so clearly set forth that it could
    traditionally have been enforced through a writ of
    mandamus.” Hells 
    Canyon, 593 F.3d at 932
    .
    Only two provisions of AR 70-25, as promulgated in
    1988, could potentially provide the basis for a judicially
    enforceable duty to provide medical care. Neither does.
    A.
    1.
    The first is Chapter 3–1(k) (subsection (k)), which
    provides, “Volunteers are authorized all necessary medical
    care for injury or disease that is a proximate result of their
    participation in research.” This subsection is not an
    “unequivocal command” to provide medical care. That is,
    while the authorization in subsection (k) certainly removes a
    barrier to volunteers’ receipt of medical care—making it
    clear, at least, that volunteers should not be denied medical
    care for lack of authorization—it does not clearly require the
    Army to provide medical care. This is a far cry from the
    typical mandatory language we usually require in section
    706(1) cases. See Rivas v. Napolitano, 
    714 F.3d 1108
    , 1111
    (9th Cir. 2013) (observing that “[t]he mandatory language
    36        VIETNAM VETERANS OF AMERICA V. CIA
    used in the regulation makes the act of reconsideration non-
    discretionary”).
    The majority, of course, believes the more “natural
    reading” of the word “authorized” is that “the volunteers are
    entitled to receive the ‘necessary medical care’ specified in
    the subsection.” But regardless of how “natural” the majority
    believes its reading to be, it is not the only plausible reading.
    The only thing that subsection (k) makes clear is that
    volunteers are authorized to receive medical care, which is
    one or two logical steps away from the majority’s conclusion
    that the Army has a legal obligation to provide them with that
    medical care. Although it is possible to read into the text of
    subsection (k) the assumption that the authorization is the
    only thing volunteers need in order to be entitled to medical
    care, and the assumption that the Army has a duty to provide
    medical care to anyone who is entitled to it, it is also possible
    to read the text of subsection (k) without those assumptions.
    Because the text is reasonably open to interpretation, it does
    not state an unequivocal command.
    2.
    Subsection (k)’s “authorization” for medical care, in
    addition to not being legally required, also is not discrete
    agency action. Discrete agency action for purposes of section
    706(1) is a “precise, definite act,” like the promulgating of a
    rule or the taking of some decision by a statutory deadline.
    
    SUWA, 542 U.S. at 63
    . The phrase “[v]olunteers are
    authorized all necessary medical care for injury or disease
    that is a proximate result of their participation in research,”
    does not qualify as “the ordering of a ‘precise, definite act . . .
    about which [an official] ha[s] no discretion whatever.’” 
    Id. This is
    most easily demonstrated by comparing subsection (k)
    VIETNAM VETERANS OF AMERICA V. CIA                  37
    to subsection (h)—the “duty to warn” subsection—which
    does command discrete agency action.
    Subsection (h) unambiguously identifies which agency or
    officers (“Commanders”; “MACOM”) are “legally required”
    (“have an obligation”; “must establish”) to perform a
    “discrete action,” (“provide [volunteers] with any newly
    acquired information”) which is described “precise[ly]” and
    “definite[ly]”:
    •   What: “information that may affect their well-
    being”;
    •   When: “when [it] becomes available” and “even
    after the individual volunteer has completed his or
    her participation in research”;
    •   To Whom: “research volunteers”—“[t]o
    accomplish this, [the Army] must establish a
    system which will permit identification of
    volunteers who have participated in research . . .
    and take actions to notify volunteers of newly
    acquired information.”
    Subsection (k), in contrast, leaves us to guess at which
    agency officer is obligated to provide the medical care
    (assuming, of course, that “authorized” means “required”—it
    does not), what such medical care would consist of, or when
    and how long medical care must be provided (only during
    research? only in “emergency” situations? forever?). As a
    result, subsection (k) “lack[s] the specificity requisite for
    agency action.” 
    SUWA, 542 U.S. at 66
    .
    38       VIETNAM VETERANS OF AMERICA V. CIA
    B.
    Only one other provision of AR 70-25 could possibly
    provide the basis for a judicially enforceable duty to provide
    medical care: Chapter 2–5(j) (subsection (j)). Subsection (j)
    provides, “The Surgeon General . . . will . . . [d]irect medical
    followup, when appropriate, on research subjects to ensure
    that any long-range problems are detected and treated.”
    Subsection (j), like subsection (k), lacks the usual language
    of obligation. Subsection (j) contemplates action by the Army
    Surgeon General only “when appropriate.” That grant of
    discretion prevents us from concluding that this language
    represents a “specific, unequivocal command” directing the
    Surgeon General to provide medical care.
    C.
    For these reasons I would affirm the district court’s
    summary judgment against Plaintiffs on their claims for
    medical care, but on the alternative ground that their claim is
    not judicially enforceable under section 706(1) of the APA.
    I am not unsympathetic to the notion that those who have
    served our country—especially those who have risked their
    health and well-being in that service—should have access to
    appropriate medical care. However, the Supreme Court has
    counseled us, and we have recognized, that “[e]ven if a court
    believes that the agency is withholding or delaying an action
    the court believes it should take, the ‘ability to compel agency
    action is carefully circumscribed to situations where an
    agency has ignored a specific legislative command.’”
