There are three Military Departments within the Department of Defense: the Department of the Army, which the United States Army is organized within. the Department of the Navy, which the United States Navy and the United States Marine Corps are organized within.
During World War I, the War Department was given supervision over the newly created National Guard, and under the National Defense Act of 1916, the officersâ reserve corps was created within the department. This act also established the office of Assistant Secretary of War to coordinate the procurement of munitions.he NME was renamed the Department of Defense (DoD) in 1949. In the succeeding years of the Cold War, the DoD (commonly referred to as the Pentagon) grew into the largest of all U.S. governmental institutions as American military operations became tantamount in U.S.-Soviet jockeying for international dominance.
