I have looked through the threads and have not found how this would work or even if it is possible. I keep getting people telling me that it is not possible but from serving in iraq. i know absolutely, that a chinook can carry a tank and a small hummwv can fit in some variations of chopper Cargo bay. My question to you guys is if it possible in the game and , if so, how? I would like to put a hmmwv In anyone of the choppers cargo bay. Thank You in Advance!
