304 (h) The number of officers designated for supply duty serving on active duty in the combined grades of colonel, lieutenant colonel, and major may not exceed 8 percent of the sum of the numbers of officers prescribed for those grades as computed or determined under subsection (c). The Secretary, whenever the needs of the service require but at least once annually, shall compute the number of officers designated for supply duty authorized for these combined grades under this section. The number so computed is the number of officers de^gnated for supply duty serving on active duty prescribed for the grades concerned. However, if the Secretary determines at the time of making this computation that the number of officers designated for supply duty required to meet the needs of the service in the combined grades is less than the prescribed number as computed, the lesser number becomes the prescribed number. (i) The prescribed numbers of officers computed or determined under this section may not be varied between computations. However, the prescribed number for a grade is temporarily increased during the period between one computation and the next succeeding computation by— (1) the number of officers originally appointed in that grade during that period; (2) the number of officers of the Marine Corps Reserve ordered to active duty in that grade during that period; and (3) the number of officers of that grade for whom vacancies exist in the next higher grade but whose promotion has been delayed for any reason. (j) For the purpose of this section, each officer is counted in the grade in which he is serving, whether under a permanent or a temporary appointment. However, each officer serving under an appointment in the grade of general or lieutenant general and each officer in a grade to which he was appointed under section 5597 or promoted under section 578T of this title is counted in the grade he would hold had he not been so appointed or promoted. § 5444. Navy: staff corps oflBicers on active d u t y Ca) The number of officers serving on active duty in the grade of rear admiral in the Medical Corps, the Supply Corps, the Chaplain Corps, the Civil Engineer Corps, and the Dental Corps, respectively, excluding any rear admiral serving as a chief of bureau, may not exceed, in each corps, a number appropriate to the total number of officers in that corps serving on active duty, as set forth in the following tables. If the total number of officers on active duty in any corps falls between two strengths shown in the first column of the appropriate table, the number of rear admirals is determined by proportionate interpolation between the numbers for the two strengths. If the number of officers on active duty in a corps is less than the smallest tabulated number for the corps concerned, the number for the grade of rear admiral in that corps is ^i o of 1 percent of the total number of officers serving on active duty in the corp>s.
