(c)Limitation on Appropriations for Military Personnel.—No funds may be appropriated for any fiscal year to or for—

(2) the use of the Selected Reserve of any reserve component of the armed forces unless the end strength for the Selected Reserve of that component for that fiscal year has been authorized by law; or
(3) the use of reserve component personnel to perform active duty or full-time National Guard duty under subsection (b) unless the strength for such personnel for that reserve component for that fiscal year has been authorized by law.
(d)Military Technician (Dual Status) End Strengths To Be Authorized by Law.—Congress shall authorize for each fiscal year both the minimum end strength for non-temporary military technicians (dual status) and the end strength for temporary military technicians (dual status) for each reserve component of the Army and Air Force. Funds available to the Department of Defense for any fiscal year may not be used for the pay of a military technician (dual status) during that fiscal year unless the technician fills a position that is within the number of such positions authorized by law for that fiscal year for the reserve component of that technician. This subsection applies without regard to section 129 of this title. In each budget submitted by the President to Congress under section 1105 of title 31, the minimum end strength for non-temporary military technicians (dual status), and the end strength for temporary military technicians (dual status), requested for each reserve component of the Army and Air Force shall be specifically set forth.
(e)End-of-Quarter Strength Levels.—
(1) The Secretary of Defense shall prescribe and include in the budget justification documents submitted to Congress in support of the President’s budget for the Department of Defense for any fiscal year the Secretary’s proposed end-of-quarter strengths for each of the first three quarters of the fiscal year for which the budget is submitted, in addition to the Secretary’s proposed fiscal-year end-strengths for that fiscal year. Such end-of-quarter strengths shall be submitted for each category of personnel for which end strengths are required to be authorized by law under subsection (a) or (d). The Secretary shall ensure that resources are provided in the budget at a level sufficient to support the end-of-quarter and fiscal-year end-strengths as submitted.
(2)
(A) After annual end-strength levels required by subsections (a) and (d) are authorized by law for a fiscal year, the Secretary of Defense shall promptly prescribe end-of-quarter strength levels for the first three quarters of that fiscal year applicable to each such end-strength level. Such end-of-quarter strength levels shall be established for any fiscal year as levels to be achieved in meeting each of those annual end-strength levels authorized by law in accordance with subsection (a) (as such levels may be adjusted pursuant to subsection (f)) and subsection (d).
(B) At least annually, the Secretary of Defense shall establish for each of the armed forces (other than the Coast Guard) the maximum permissible variance of actual strength for an armed force at the end of any given quarter from the end-of-quarter strength established pursuant to subparagraph (A). Such variance shall be such that it promotes the maintaining of the strength necessary to achieve the end-strength levels authorized in accordance with subsection (a) (as adjusted pursuant to subsection (f)) and subsection (d).
(3) Whenever the Secretary establishes an end-of-quarter strength level under subparagraph (A) of paragraph (2), or modifies a strength level under the authority provided in subparagraph (B) of paragraph (2), the Secretary shall notify the Committee on Armed Services of the Senate and the Committee on Armed Services of the House of Representatives of that strength level or of that modification, as the case may be.
(f)Authority for Secretary of Defense Variances for Active-Duty and Selected Reserve Strengths.—Upon determination by the Secretary of Defense that such action is in the national interest, the Secretary may—
(1) vary the end strength authorized pursuant to subsection (a)(1)(A) for a fiscal year for any of the armed forces by a number equal to not more than 3 percent of that end strength;
(2) vary the end strength authorized pursuant to subsection (a)(1)(B) for a fiscal year for any of the armed forces by a number equal to not more than 3 percent of that end strength;
(3) vary the end strength authorized pursuant to subsection (a)(2) for a fiscal year for the Selected Reserve of any of the reserve components by a number equal to not more than 3 percent of that end strength; and
(4) vary the maximum strength authorized pursuant to subsection (b)(1) for a fiscal year for certain reserves on active duty for any of the reserve components by a number equal to not more than 10 percent of that strength.
(g)Authority for Service Secretary Variances for Active-duty and Selected Reserve End Strengths.—
(1) Upon determination by the Secretary of a military department that such action would enhance manning and readiness in essential units or in critical specialties or ratings, the Secretary may—
(A) vary the end strength pursuant to subsection (a)(1)(A) for a fiscal year for the armed force or forces under the jurisdiction of that Secretary by a number not equal to more than 2 percent of such authorized end strength;
(B) vary the end strength pursuant to subsection (a)(1)(B) for a fiscal year for the armed force or forces under the jurisdiction of that Secretary by a number not equal to more than 2 percent of such authorized end strength; and
(C) vary the end strength pursuant to subsection (a)(2) for a fiscal year for the Selected Reserve of the reserve component of the armed force or forces under the jurisdiction of that Secretary by a number equal to not more than 2 percent of such authorized end strength.
(2) Any variance under paragraph (1)(A) of the end strength for an armed force for a fiscal year shall be counted as part of the variance for that armed force for that fiscal year authorized under subsection (f)(1). Any variance under paragraph (1)(B) of the end strength for the Selected Reserve of a reserve component of an armed force for a fiscal year shall be counted as part of the variance for that Selected Reserve for that fiscal year authorized under subsection (f)(3).
(3) The Secretary of the military department concerned shall promptly notify the congressional defense committees if such Secretary exceeds a variance under paragraph (1), and at least once every 90 days thereafter for so long as such end strength is outside such variance. Each such notification shall include the following:
(A) Modified projected end strengths for active and reserve components of the armed force or forces for which such Secretary exceeds such variance.
(B) An identification of any budgetary effects projected as a result of such modified end strength projections.
(C) An explanation of any effects on readiness resulting from such modified end strength projections.
(h)Adjustment When Coast Guard is Operating as a Service in the Navy.—The authorized strength of the Navy under subsection (a)(1) is increased by the authorized strength of the Coast Guard during any period when the Coast Guard is operating as a service in the Navy.
(i)Certain Personnel Excluded From Counting for Active-Duty End Strengths.—In counting personnel for the purpose of the end strengths authorized pursuant to subsection (a)(1), persons in the following categories shall be excluded:
