This is my favorite type of kill to get on the battlefield. Nothing is more rewarding for me than getting a head shot on a good chopper pilot with a bolt action rifle. Plus it may lead to chopper thievery which can completely turn the tide of a game. I would trade a 20 kill streak for one good chopper snipe any day.
Anyone else have a different favorite type of kill? The kind of kill that gets you out of your seat.
