It's an "Ike Jacket". Color would indicate Air Force. Could have been worn by any number of people in lots of different movies. I'll guess Duke and Jet Pilot, especially since he wore both Army and Air Force uniforms in the movie.
Spoiler Alert-
of course it's a lot easier if you check the properties of the picture and it tells you. :^)
