Updated September 2, 2003 ABOUT THE ALMANAC

    The mission of the Department of Defense is to provide the military forces needed to deter war and to protect the security of our country

   The Department of Defense is a Cabinet-level Organization. Reporting to it are the three military departments (Army, Navy and Air Force) and 15 defense agencies. The four armed services are subordinate to their military departments. The Marine Corps is a second armed service in the Department of the Navy. The military departments are responsible for recruiting, training and equipping their forces, but operational control of those forces is assigned to one of the unified combatant commands.
