Hundreds. And Im sure your all great at heart, but a word of warning, the RAAF used to opearte helicopters, and operated along similar lines to the way our AT fleet do (or don't dependant on viewpoint) business. They don't opereate helicopters anymore...the Army do.
Much as I think your all a bunch of money grabbing slackers, I'd rather you were operating the AT Fleet than the RLC/AAC, so be good chaps and get a grip.
