The 12th Aero Squadron was a United States Army Air Service unit that fought on the Western Front during World War I. The squadron was assigned as a Corps Observation Squadron, performing short-range, tactical reconnaissance over the I Corps, United States First Army sector of the Western Front in France, providing battlefield intelligence.
