The Department of Defense is responsible for the security of the United States and oversees all branches of the armed forces; the Army, Navy, Air Force and Marine Corps, along with all special forces and weapons systems. Within the DoD are the secretary of defense—the chief defense policy advisor; and the chairman of the Joint Chiefs of Staff—the chief military advisor.
