Joint Chiefs of Staff Ernest J. King Chief of Naval Operations George C. Marshall Hap Arnold William D. Leahy Harry Hopkins Navy
In 1942, Roosevelt formed a new body, the Joint Chiefs of Staff, which made the final decisions on American military strategy. Admiral Ernest J. King as Chief of Naval Operations commanded the Navy and Marines, while General George C. Marshall led the Army and was in nominal control of the Air Force, which in practice was commanded by General Hap Arnold. The Joint Chiefs were chaired by Admiral William D. Leahy, the most senior officer in the military. Roosevelt avoided micromanaging the war and let his top military officers make most decisions. Roosevelt's civilian appointees handled the draft and procurement of men and equipment, but no civilians—not even the secretaries of War or Navy—had a voice in strategy. Roosevelt avoided the State Department and conducted high-level diplomacy through his aides, especially Harry Hopkins, whose influence was bolstered by his control of the Lend Lease funds.
