The U.S. Air Force can trace its roots back to the Aeronautical Division, Signal Corps, formed as a part of the army in 1907. In 1947, after several changes, W. Stuart Symington was sworn in as the Air Force's first Secretary, and it became its own branch. Among other things, they assist in the recovery of troops and air support of other armed forces. Current and past Air Force members can use this sticker to show pride in their branch.
