The characters Iron Man (left) and War Machine (right) are featured in the film "Iron Man 2". The Air Force agreed to participate in the film because it was an opportunity to highlight their capabilities and showcase Airmen to a world-wide audience. War Machine is marked with official Air Force symbols, including the Air Force logo. An exclusive screening was shown to Sheppard Air Force Base, Texas, and two other bases May 6, 2010.
