The purpose of this report is to present the findings of the Department of Defense review of general and flag officer requirements. In June 1966, the Assistant Secretary of Defense (Manpower) appointed a military study group to review all requirements for general/flag officers within and outside of the Department of Defense. The major objectives of this review were to determine the total national requirement for such officers and to evaluate the adequacy of present authorizations to meet these requirements. The Study Group reviewed a total of 1991 requirements submitted by the military services, the JCS, and the OSD. The Study Group found 1620 to be valid requirements of which 42 were identified as unique requirements which should be excluded from accountability against general/flag officer authorizations. In addition, it was found that the requirements of the health, legal and religious specialties could not be determined in precisely the same terms as pure military requirements and the Study Group, therefore, developed separate authorization tables, based on the officer population of these specialties, which, at projected 30 June 1968 strengths, would authorize a maximum of 105 general/flag officers for these specialties. Thus, the Study Group determined that the national requirement for general/flag officers is 1683 (1620 minus 42 plus 105). This number exceeds present legal authorizations. (Author).
