------------------------------------------------------------------------

The Department of Defense is responsible for providing the military forces needed to deter war and protect the security of our country.

The major elements of these forces are the Army, Navy, Marine Corps, and Air Force, consisting of about 1.3 million men and women on active duty. They are backed, in case of emergency, by the 825,000 members of the Reserve and National Guard. In addition, there are about 600,000 civilian employees in the Defense Department.

Under the President, who is also Commander in Chief, the Secretary of Defense exercises authority, direction, and control over the Department, which includes the separately organized military departments of Army, Navy, and Air Force, the Joint Chiefs of Staff providing military advice, the combatant commands, and defense agencies and field activities established for specific purposes.

The National Security Act Amendments of 1949 redesignated the National Military Establishment as the Department of Defense and established it as an executive department (10 U.S.C. 111), headed by the Secretary of Defense.

Structure

The Department of Defense is composed of the Office of the Secretary of Defense; the military departments and the military services within those departments; the Chairman of the Joint Chiefs of Staff and the Joint Staff; the combatant commands; the defense agencies; DOD field activities; and such other offices, agencies, activities, and commands as may be established or designated by law, or by the President or the Secretary of Defense.

Each military department is separately organized under its own Secretary and functions under the authority, direction, and control of the Secretary of Defense. The Secretary of each military department is responsible to the Secretary of Defense for the operation and efficiency of his department. Orders

T217558.014

to the military departments are issued through the Secretaries of these departments or their designees, by the Secretary of Defense, or under authority specifically delegated in writing by the Secretary of Defense or provided by law.

The commanders of the combatant commands are responsible to the President and the Secretary of Defense for accomplishing the military missions assigned to them and exercising command authority over forces assigned to them. The operational chain of command runs from the President to the Secretary of Defense to the commanders of the combatant commands. The Chairman of the Joint Chiefs of Staff functions within the chain of command by transmitting the orders of the President or the Secretary of Defense to the commanders of the combatant commands.
