Army Ground Forces
The United States Army Ground Forces, formed on March 9, 1942, was responsible for training, equipping and mobilizing all Army units except those of the Army Air Corps. In 1950 the Army Ground Forces were renamed as the Army Field Forces.
Notes
The branch insignia for Army Ground Forces in World War II is currently used by Army Forces Command, who's mission is similar to that of the Army Ground Forces. The AGF patch can be seen on the uniforms of officers in the War Department scene near the beginning of the film.
