Sec. 516. Based upon the number of actual and anticipated vacancies in the Air Force Reserve in the grade of colonel, the Secretary shall furnish to a selection board the names of officers of the Air Force Reserve to be considered for promotion and shall direct the board to recommend a number prescribed by him for promotion to that grade. Each list furnished shall include— (1) the name of the senior officer in the grade of lieutenant colonel whose name is not on a recommended list for promotion; and (2) the names of such additional officers as the Secretary may prescribe, in order of their seniority. The board shall recommend the prescribed number of those officers which it considers to be the best qualified of those named for consideration. A Reserve officer recommended for promotion under this section may be promoted only to fill a vacancy.
