"SHARK claimed “a single sharp rifle crack rang out..."
I'd like to meet the guy who shot this down with a "rifle" 
I'm just surprised they didn't call it a fully automatic howitzer with exploding shells. Or some ****.
All seriousness though, there is some kid about 50 miles east of Kandahar that you want to meet then. Shot down a Raven UAV (small, low altitude, battery powered) with what was likely a old piece of **** FAL (or so we believe).
