The 6th Infantry Division was an infantry division of the United States Army active in World War I, World War II, and the last years of the Cold War. Known as "Red Star", it was previously called the "Sight Seein' Sixth".

A corps area was a geographically-based organizational structure of the United States Army used to accomplish administrative, training, and tactical tasks from 1920 to 1942. Each corps area included divisions of the Regular Army, Organized Reserve, and National Guard of the United States. Developed as a result of serious mobilization problems during World War I, this organization provided a framework to rapidly expand the Army in times of war or national emergency, such as the Great Depression.
