Hell yeah we slept in the deployment area. We were deploying to Afghanistan by air, and after showing up on base with the hand-carry gear that would go on the plane with us (other gear was a combination of cargo flight and stuff already there) we jumped on the passenger buses to take us to the nearby air base we would fly out of. It was still early when we got there, both early in the morning and early for the flight. You always build in plenty of extra time; “hurry up and wait” is the mantra. So we spent a few hours before the plane even showed up just waiting in the passenger terminal, which was just a big hangar with a snack bar on one end and unlimited coffee. Most of us slept for a bit. And before you ask where, the answer is always “on the floor”.
