You probably have read about Dipprasad Pun on the news, but this version is much much better!

And so, just as suddenly as the mournful mooing of the cow had broken the peaceful silence of the Afghan countryside, now the sky was filled with 7.62 millimeter bullets, epic profanity, and the tell-tale contrails of rocket-propelled grenade fire, as out of fucking nowhere somewhere between 15 and 30 Taliban warriors launched a balls-out attempt to smear poor Sergeant Pun all across the roof of his guardhouse. Gunfire was whizzing in from every direction, rock and smoke was getting kicked up all over the place, and Pun pretty much nearly shit a brick as RPG fire blew giant chunks out of the building he was standing on.
For the next fifteen minutes or so, Sergeant Dipprasad Pun went completely fucking out of his mind batshit insane. Surrounded on all sides in a scene that makes me think of the rooftop finale for Mercy Hospital in Left 4 Dead, Pun fought off assaults from all sides of his fortified rooftop position, somehow avoiding being shot by thirty-plus guys with automatic weapons and explosives launchers as he laid down a curtain of bullets so over-the-top that it would have made John Woo jizz. Firing from the hip like the goddamned Terminator wasting those cop cars with the minigun in T2, Pun held back the Taliban assault on the town, blowing through all 400 rounds of ammunition for the machine gun – every single bullet in the rooftop bunker – in the span of just a few minutes. When the supply of large-caliber heavy weapons ammunition ran out, Pun ditched the MG and started grabbing grenades, two at a time, chucking them in every direction like he was dishing out beads from a Mardi Gras rooftop (only instead of topless drunk babes he was throwing them at terrorists, which is pretty much the exact opposite of topless drunk babes, but whatever).
