I have seen Ospreys where a crewman uses a machine gun on the lowered ramp.

Of course the non-PC clip from “FMJ” film is one of my favorites...

What worries me about these types of vehicles is that there are now thousands of former qdaffi manpads,shoulder fired weapons, floating around the mid-east in the hands of who knows whom. My question is how many would it take to shoot down one of these Ospresy by a terror type standing under a tree where he can’t be seen?
