You thought the war dog craze of '11 was over, didn't you? Surprise! KitUp's got a nice little look at soldiers in Afghanistan, and the strategic strays they befriend. This video contains both puppies and a SAW machine gun.
The soldiers describe how the animals -- usually found in pretty rough shape -- come to be more than just friends. They're invaluable at detecting bad guys in the dark while on patrol, though barking can be a battlefield liability during stealth situations. Either way, it must be nice to have a break from explosions and blood and just pet a dog for a little bit. [KitUp!]
