I think this video is from Iraq, though I may be wrong so please correct me if you know more about it.
The video shows a group of Islamic fighters behind a dirt hill used as a cover having themselves some fun on the battle field. Every now and then they poke a gun over the hill and fire in the general direction of their enemy’s presumed position.
Toward the end of the video, one of the fighters sprays the area behind the hill nonchalantly with fire from a machine gun, like he was in a Rambo movie. But just as he was about to conclude his emptying the magazine, Rambo wannabe got taken out by the enemy sniper with a headshot he never saw coming. His hat flew, and he dropped lifeless to the ground. And just like that, all his lights went out.
