In Rambo 3, he is driving a Russian tank, and then all of a sudden, he moves up a few inches to the gunnerās controls and starts firing. I have had the opportunity to get in a few Russian made tanks, as well as driving US made tanks, and I can tell you that this is physically impossible! The driverās compartment is separated from the turret and is extremely cramped. Plus in one scene he fires an RPG from inside the cockpit of a helicopter! The back blast would have taken out the entire rear of that chopper! Very unrealistic!
