My old coworker worked with movie studies (Valley of Elah was one) as a consultant providing military like training to the actors. (Enough to make them look like military personell) if the business he was in didn't fall apart they had a hind helicopter on the way.. shipping and certification was more expensive than the chopper... besides that, it was mostly WW2 era jeeps, tanks, etc..

Still that APC looks pretty fun :-D
