I wear a military green colored t-shirt with the United States Army Air Corps Insignia on the chest area along with my 1940's Coca * Cola logo red colored ball cap hat. The United States Army Air Corps (USAAC) was active from 2 July 1926 - 9 March 1942 and was disbanded 18 September 1947. The Lineage of the United States Air Force are as follows : Aeronautical Division, Signal Corps 1 August 1907 - 18 July 1914, Aviation Section, Signal Corps 18 July 1914 - 20 May 1918, Division of Military Aeronautics 20 May 1918 - 24 May 1918, Air Service, U.S. Army 24 May 1918 - 2 July 1926, U.S. Army Air Corps 2 July 1926 - 20 June 1941, U.S. Army Air Forces 20 June 1941 - 18 September 1947 and United States Air Force 18 September 1947 - present. The United States Army Air Forces (USAAF or AAF) was the major land-based aerial warfare service component of the United States Army and de facto aerial warfare service branch of the United States during and immediately after World War II (1941-1945). It was created on 20 June 1941 as successor to the previous United States Army Air Corps and is the direct predecessor of the United States Air Force, today one of the six armed forces of the United States. You're welcome for the clarification.
