The Department of Defense (DoD) is a department of the federal government and has three main components: The departments of the Army, Navy, and Air Force. The DoD is housed in the Pentagon building. The department's roles and limits are contained in Title 10 of the US Code. This section of the law has five components: Subtitle A refers to General Military Law, Subtitle B to the Army, Subtitle C to the Navy and the Marine Corps, Subtitle D to the Air Force and Subtitle E to Military Reserves. Important agencies within the DoD include the Defense Information Systems Agency (DISA), National Security Agency (NSA), the Missile Defense Agency, and the Defense Intelligence Agency (DIA). The DoD receives the largest portion of each year's federal discretionary spending budget.
