(1)
A regular officer on the active-duty list of the Army, Navy, Air Force, or Marine Corps may be considered for selective early retirement by a selection board convened under section

(b) of this title if the officer is described in any of subparagraphs (A) through (D) as follows:

The Secretary of the military department concerned shall specify the number of officers described in paragraphs (1)(A) and (1)(B) which a selection board convened under section
611
(b) of this title may recommend for early retirement. Such number may not be more than 30 percent of the number of officers considered in each grade in each competitive category.

An officer in a grade below brigadier general or rear admiral (lower half) who is recommended for early retirement under this section or section
638a of this title and whose early retirement is approved by the Secretary concerned shall—
(A)
be retired, under any provision of law under which he is eligible to retire, on the date requested by him and approved by the Secretary concerned, which date shall be not later than the first day of the seventh calendar month beginning after the month in which the Secretary concerned approves the report of the board which recommended the officer for early retirement; or

if the officer is not eligible for retirement under any provision of law, be retained on active duty until he is qualified for retirement under section

(3)
The Secretary concerned may defer for not more than 90 days the retirement of an officer otherwise approved for early retirement under this section or section

The authority of the Secretary to grant such a deferral may not be delegated.
(c)
So long as an officer in a grade below brigadier general or rear admiral (lower half) holds the same grade, he may not be considered for early retirement under this section more than once in any five-year period.
(d)
The retirement of an officer pursuant to this section shall be considered to be an involuntary retirement for purposes of any other provision of law.
