I don't know if you saw the reports early in the Afghan conflict, but Air Force FACs were assigned to Afghan military units and were living in the same conditions as they were. These weren't the guys complaining. The guy who complained and alerted the media was living in fairly decent conditions considering the situation.
I have a lot of admiration for the other branches and I'll admit that the "Average" Air Force guy has it quite a bit better than the "Average" member of any of the other services.
