How the U.S. military is organized

The Department of Defense has three military departments: the Army, the Navy and the Air Force. The Marine Corps sits within the Department of the Navy and the Space Force within the Department of the Air Force, according to the Congressional Research Service. DOD counts more than 2.8 million service members and civilians at over 4,800 sites, and it has used “Department of War” as a secondary designation since September 5, 2025, under Executive Order 14347.1

The departments organize, train and equip forces; the combatant commands use them in operations. CRS explains that under Title 10, Section 162, the operational chain of command runs from the President to the Secretary of Defense to the combatant commanders. The Chairman of the Joint Chiefs of Staff may pass orders along that chain but has no command authority.2 That split is why a deployment story names a command such as CENTCOM or INDOPACOM, while a training or equipment story names a service. Our guide to the 11 combatant commands covers each one.
