Damn that looked great, very very nicely done indeed. Only things I found to be unrealistic are the slow firerate on those G36s, and the most unrealistic thing was the sniper rifle, which infact was a Crosman 1077 semiautomatic pellet gun (I have one at home, available at a canadian tire near you
, and no its NOT bolt action as it was shown in the clip.
Otherwise, its very nice.
Cheers,
