This is stupid, when I was a SAW gunner I just shouldered the motherfucker like normal. Little harder with a 240 though...
They'll realize how dumb this shit is the first time he has to go in prone and can't get there. It's big enough they could just issue him a fucking tripod!
What they DO need, and what I could have used, would have been a "death machine" setup with a Hughes feed chute attached to the gun and to a 600rd. belt in an ammo can on your back or belt. Oh yeah!
