iraqi sniper training

As I recall a few months back there were a whole series of those vids shot with lots of people getting abused by something like .50 some wildcat. There was one dude that took it like a man braced himself letr rip and did quite well. After the big boom he calmly set the cannon down popped the bolt back ejecting the empty case and then some other guy said would you like to try it again? he mouthed something like f**K you....... I had to watch all them people get pounded several times
