61 STAT.] 80TH CONG. , 1ST SESS.-CH. 512-AUG. 7 , 1947 of section 513 of this title, and except in those cases governed by the proviso to the first sentence of subsection 507 (d) of this title. (b) Based upon the number of vacancies existing and anticipated in the grade of brigadier general in the Regular Army and the number of officers desired in that grade, the Secretary of War shall direct a selection board to select and recommend a prescribed number of officers for promotion to that grade, and, in order to insure that the Army will have adequate numbers of officers in the grade of brigadier general with experience qualifying them for service in or with the several branches, arms, and services, he may, in his discretion, direct that, of the number to be selected and recommended, specified numbers have experience qualifying them for service in or with certain specified branches, arms or services. The Secretary of War shall furnish to such board a list of the names of the officers to be considered. The list of names furnished for consideration shall include the names of the senior officers below the junior in the permanent grade of brigadier general whose names are not carried on the recommended list for promotion to the grade of brigadier general and the names of addi- tional such officers in the order that their names appear next below theirs on the applicable promotion lists, as the Secretary of War may prescribe, and, until June 30,1948, in addition thereto may include the names of any officers in permanent grade below that of brigadier general who served during the current war in any general officer grade under temporary appointment. From among the officers named for consideration, the designated selection board shall select and recom- mend the prescribed number, including any prescribed numbers whose experience qualifies them for service m or with a designated branch, arm, or service. The officers selected and recommended shall be those who, in the opinion of the board, are the best qualified officers of those listed for consideration. (c) The names of officers who are selected and recommended for promotion to the grade of brigadier general in the Regular Army shall be carried on a permanent recommended list of officers for promotion to that grade. Upon selection, the names of such officers shall be placed on the recommended list at the foot thereof arranged among themselves according to precedence to be determined by the Secretary of War. The number of officers to be selected and recommended by designated selection boards for promotion to the grade of brigadier general in the Regular Army shall be determined by the Secretary of War. It is not mandatory that the Secretary of War direct the selection and recommendation of numbers sufficient to produce the number authorized for that grade; but officers who are selected and recommended for promotion to that grade by any such selection board, and whose names are not removed from the recommended list by the President, shall be nominated, and by and with the advice and consent of the Senate appointed, in that grade as soon as there is a vacancy in the number authorized for that grade. (d) The ratio of the number of officers which the Secretary of War names for consideration by any selection board for promotion to the grade of brigadier general in the Regular Army, to the number of officers which he directs such selection board to select from among those so named, may be as desired by the Secretary of War, but no officer shall be considered or selected by any selection board more than one year prior to the date on which it is anticipated he will, if selected, be appointed in that grade. After June 30, 1949, officers must have completed at least one year's service under permanent appointment in the grade of colonel in the Regular Army, before being nominated or appointed in the grade of brigadier general in the Regular Army. 899 Ante, p. 893.
