I was on Isla Innocents in BC2. I was defending and I was sniping. A black hawk was floating around our base, so I took a couple of pot shots and both hit the gunners by some stroke of fate. Obviously shocked, the pilot retreats to the base. He then flies back towards us with a full crew. I take a couple more shots and hit a passenger. I take one last shot and nailed the pilot. I hadn't even known sniping people out of choppers was possible until that round. Ah, nothing is more beautiful that seeing those points pop up after a random shot.
