((a)) Each agreement made under shall provide that the member may not be released from active duty without his consent during the period of the agreement—

((1)) because of a reduction in the actual personnel strength of the armed force concerned, unless the release is in accordance with the recommendation of a board of officers appointed by an authority designated by the Secretary concerned to determine the members to be released from active duty under regulations prescribed by the Secretary; or

((2)) for any other reason, without an opportunity to be heard by a board of officers before the release, unless he is (A) dismissed or discharged under the sentence of a court-martial, (B) released because of an unexplained absence without leave for at least three months, (C) released because he is convicted and sentenced to confinement in a Federal or State penitentiary or correctional institution and the sentence has become final, or (D) released because he has been considered at least twice and has not been recommended for promotion to the next higher grade or because he is considered as having failed of selection for promotion to the next higher grade and has not been recommended for promotion to that grade, under conditions that would require the release or separation of a reserve officer who is not serving under such agreement.

((b)) A member who is released from active duty without his consent before the end of his agreement made under is entitled to an amount computed by multiplying the number of years and fractions of a year of his unexpired period of service under the agreement by the sum of one month’s basic pay, special pay, and allowances to which he is entitled on the day of his release. The amount to which a member is entitled under this subsection is in addition to any pay and allowances to which he is otherwise entitled. For the purposes of this subsection, a fraction of a month of 15 days or more is counted as a whole month, and a fraction of a month of less than 15 days is disregarded. This subsection does not apply to a member if he is—

((1)) released for a reason described in subsection (a)(2)(A)–(C);

((2)) released because of a physical disability resulting from his intentional misconduct or wilful neglect;

((3)) eligible for retired pay, separation pay, or severance pay under another provision of law;

((4)) placed on a temporary disability retired list; or

((5)) released to accept an appointment, or to be enlisted, in a regular component of an armed force.
