Military Departments
The three military departments within the Department of
Defense (DOD), created by the National Security Act of
1947, are the Department of the Army, the Department of
the Navy, and the Department of the Air Force (P.L. 80-
253). A military department prepares and provides
strategic, conventional, and special operations forces for
military operations conducted by DOD. Each department
has an executive headquarters for administering its
activities, personnel, and organizations. The type and
number of personnel permitted to work in an executive
headquarters are limited by law and differ among the three
departments (Table 1).

Note: Personnel limits do not apply in time of war and they may be
increased by 15% of such limits in time of national emergency.
Secretary of the Military Department
The military departments are led by a civilian secretary
whom the President of the United States appoints with the
advice and consent of the Senate. The authority of a
secretary runs from the President through the Secretary of
Defense. The secretaries of the military departments are
responsible for training, equipping, and organizing their
departments' armed services. A secretary may present
departmental recommendations to Congress after notifying
the Secretary of Defense. Principal officials of the
department reporting to a secretary include the under
secretary, assistant secretaries, and general counsel. These
officials typically are appointed by the President with the
advice and consent of the Senate. Specific areas of
responsibility for the assistant secretaries include logistics,
manpower, acquisition, and financial management.
Department of the Army
The Office of the Secretary of the Army administers the
Department of the Army; secretarial authorities are set forth
in 10 U.S.C. §7013 (see below). The department's armed
service is the Army, which is the principal land force in
