divisions, each with its own Assistant Chief of Staff. There were also three deputy chiefs of staff, one each for supply, administration and the air. The Deputy Chief for Air was also the chief of the AAF. The two major commands, the AAF and GHQ. These were responsible for the preparation and training of air and ground combat units respectively. GHQ was also responsible for the defense of the continental United States, which was conducted through four defense commands, the Central, Eastern, Southern and Western, which had been formed on 17 May 1941. GHQ had been set up with the idea that it would command the forces overseas, as had occurred in World War I, but by early 1942 it was apparent that World War II would be fought in many theaters. The Chief of Staff was the chief of the WDGS and the commanding general of GHQ, but the two were quite separate entities. The chiefs of the combat arms, service arms and administrative bureaus. These were located in Washington, DC, and had responsibility for training schools and the development of doctrine. There were four armies that controlled the combat troops located in the United States, and nine corps areas that provided them with services and managed most military posts.

There were also some miscellaneous installations, such as the United States Military Academy, United States Army Command and General Staff College and the ports of embarkation. The G-4 Division of the WDGS, which was responsible for logistics, was headed from 25 November 1941 by Brigadier General Brehon B. Somervell. Supply was a critical issue, and became more so after the United States entered the war in December. The mobilization of the Army was being slowed by shortages of equipment, as was the deployment of troops overseas. If the United States Army was to take the field in 1942, production would need to be stepped up, but this was not the responsibility of G-4, but of the Under Secretary of War, Robert P. Patterson. The Office of the Under Secretary of War (OUSW) had grown from 78 people on 1 July 1939 to 1,136 on 1 November 1941. Somervell saw that the closest cooperation between G-4 and the OUSW was required, and he asked a New York attorney, Goldthwaite H. Dorr,
