The Secretary of Defense shall allocate those exclusions to the armed forces based on the number of general or flag officers required from each armed force for assignment to these designated positions.

Each position so designated shall be considered to be a joint duty assignment position for purposes of chapter 38 of this title.

(B) A reserve component officer serving in a position designated under subparagraph (A) while on active duty under a call or order to active duty that does not specify a period of 180 days or less shall not be counted for the purposes of the limitations under subsection (a) and under section 525 of this title if the officer was selected for service in that position in accordance with the procedures specified in subparagraph (C).

(2) The limitations of this section also do not apply to a number, as specified by the Secretary of the military department concerned, of reserve component general or flag officers authorized to serve on active duty for a period of not more than 365 days. The number so specified for an armed force may not exceed the number equal to 10 percent of the authorized number of general or flag officers, as the case may be, of that armed force under section 12004 of this title.

(g) Exclusion of Officers Departing From Joint Duty Assignments.—The limitations in subsection (a) do not apply to an officer released from a joint duty assignment, but only during the 60-day period beginning on the date the officer departs the joint duty assignment. The Secretary of Defense may authorize the Secretary of a military department to extend the 60-day period by an additional 120 days, except that not more than three officers on active duty from each armed force may be covered by an extension under this sentence at the same time.

(h) Active-duty Baseline.—

(1) Notice and wait requirement.—If the Secretary of a military department proposes an action that would increase above the baseline the number of general officers or flag officers of an armed force under the jurisdiction of that Secretary who would be on active duty and would count against the statutory limit applicable to that armed force under subsection (a), the action shall not take effect until after the end of the 60-calendar day period beginning on the date on which the Secretary provides notice of the proposed action, including the rationale for the action, to the Committees on Armed Services of the House of Representatives and the Senate.

(2) Baseline defined.—For purposes of paragraph (1), the term “baseline” for an armed force means the lower of—

(A) the statutory limit of general officers or flag officers of that armed force under subsection (a); or

(B) the actual number of general officers or flag officers of that armed force who, as of January 1, 2014, counted toward the statutory limit of general officers or flag officers of that armed force under subsection (a).

(3) Limitation.—If, at any time, the actual number of general officers or flag officers of an armed force who count toward the statutory limit of general officers or flag officers of that armed force under subsection (a) exceeds such statutory limit, then no increase described in paragraph (1) for that armed force may occur until the general officer or flag officer total for that armed force is reduced below such statutory limit.

(i) Joint Duty Assignment Baseline.—

(1) Notice and wait requirement.—If the Secretary of Defense, the Secretary of a military department, or the Chairman of the Joint Chiefs of Staff proposes an action that would increase above the baseline the number of general officers and flag officers of the armed forces in joint duty assignments who count against the statutory limit under subsection (b)(1), the action shall not take effect until after the end of the 60-calendar day period beginning on the date on which the Secretary or Chairman, as the case may be, provides notice of the proposed action, including the rationale for the action, to the Committees on Armed Services of the House of Representatives and the Senate.

(2) Baseline defined.—For purposes of paragraph (1), the term “baseline” means the lower of—

(A) the statutory limit on general officer and flag officer positions that are joint duty assignments under subsection (b)(1); or

(B) the actual number of general officers and flag officers who, as of January 1, 2014, were in joint duty assignments counted toward the statutory limit under subsection (b)(1).

(3) Limitation.—If, at any time, the actual number of general officers and flag officers in joint duty assignments counted toward the statutory limit under subsection (b)(1) exceeds such statutory limit, then no increase described in paragraph (1) may occur until the number of general officers and flag officers in joint duty assignments is reduced below such statutory limit.

(j) Annual Report on General Officer and Flag Officer Numbers.—Not later than March 1, 2015, and each March 1 thereafter, the Secretary of Defense shall submit to the Committees on Armed Services of the House of Representatives and the Senate a report specifying—

(1) the numbers of general officers and flag officers who, as of January 1 of the calendar year in which the report is submitted, counted toward the service-specific limits of subsection (a); and

(2) the number of general officers and flag officers in joint duty assignments who, as of such January 1, counted toward the statutory limit under subsection (b)(1).

(k) Transfer of Authorizations Among the Military Services.—(1) The Secretary of Defense may increase the maximum number of brigadier generals or major generals in the Army, Air Force, Marine Corps, or Space Force, or rear admirals (lower half) or rear admirals in the Navy, allowed under subsection (a) and section 525 of this title, and the President may appoint officers in the equivalent grades equal to the number increased by the Secretary of Defense, if each appointment is made in conjunction with an offsetting reduction under paragraph (2).

(2) For each increase and appointment made under the authority of paragraph (1) in the Army, Navy, Air Force, Marine Corps, or Space Force, the number of appointments that may be made in the equivalent grade in one of the other armed forces (other than the Coast Guard) shall be reduced by one. When such an increase and appointment is made, the Secretary of Defense shall specify the armed force in which the reduction required by this paragraph is to be made.

(3) The total number of general officers and flag officers increased under paragraph (1), combined with the total number of general officers and flag officers increased under section 526a(i)(1) ¹ of this title, may not exceed 15 at any one time.

(4) The Secretary may not increase the maximum number of general officers or flag officers under paragraph (1) until the date that is 30 days after the date on which the Secretary provides, to the Committees on Armed Services of the Senate and the House of Representatives, written notice of—

(A) such increase; and

(B) each offsetting reduction under paragraph (2), specifying the armed force and billet so reduced.
