The Defense Intelligence Agency (DIA) is a member of the U.S. Intelligence Community, and is the central producer and manager of military intelligence for the United States Department of Defense (DoD), employing over 16,500 U.S. military and civilian employees worldwide. The defense intelligence community is headed by the DIA, through its Director (who chairs the Military Intelligence Board), and it coordinates the activities of the U.S. Army, U.S. Navy, U.S. Air Force, and U.S. Marine Corps intelligence forces. The DIA and the defense intelligence community provide military intelligence to war fighters, defense policy makers, and force planners within the Department of Defense and the U.S. Intelligence Community, in support of American military planning and operations and weapon systems procurement. The DIA was established in 1961 as a result of a decision by the U.S. Secretary of Defense, Robert S. McNamara, under President John F. Kennedy, and it was designated as a Defense Department combat support agency in 1986. The Department of Defense created the DIA with the publication of Directive 5105.21, "Defense Intelligence Agency" on August 1, 1961, effective October 1, 1961.
