CWAD6 is a U.S. Army Directive from the Chief of Staff, General George C. Marshall, dated Dec. 6, 1941, that established the National Military Establishment and the Office of the Chairman of the Joint Chiefs of Staff, thus creating the modern-day Joint Chiefs of Staff. The directive also defined the line of responsibility between the different branches of the U.S. Armed Forces, assigning the War Department (now called the Department of the Army) responsibility for the Army and the Navy Department (now called the Department of the Navy) responsibility for the Navy and Marine Corps. The directive, known as the Hammond Scheme, is named after General George C. Hammond, the first Chairman of the Joint Chiefs of Staff.
