 Partly because Air Corps fire support aircraft were not always available, the chief of field artillery and other artillery officers became interested in using light aircraft organic to the artillery units.The Army experimented with using small organic aircraft for artillery fire adjustment and other functions in maneuvers at Camp Beauregard, La., in August 1940.The tests were repeated on a larger scale in the Army maneuvers in Louisiana, Tennessee, Texas, and the Carolinas in 1941.
