>>7081848AT4s have a very aggressive blast that has a nasty habit of bouncing everything on the ground up. Not as bad as the CGs, but still. All the fine dust, casings, links, 40mm case, and one poor guy's weapon make perfect sense to be doing what they are doing.
What we don't see is the the hearing damage, occasional minor brain injuries, and the weird empty feeling in your chest after the thing is fired.
