I think this is where I got my rocket genes! My dad's outfit, circa 1947. Via the Ft. Bliss Monitor:
The 1st Anti-Aircraft Guided Missile Battalion was organized at Fort Bliss in October 1945. While Operation Paperclip personnel initially did the research and development at Fort Bliss; the test firings were conducted by the guided missile battalion at White Sands. The first V-2 rocket was fired March 15, 1946, to test the engine, with the first flight May 10. From that date until 1952, 67 of these rockets were successfully launched from the proving grounds. The battalion also launched the liquid fueled WAC Corporal in February 1947. The Corporal series were considered the first American made rockets.
