Funny story of when I was stationed in Panama, we all slept in hammocks in the field. Then one day the brigade commander says, "get rid of the hammocks, there are not tactically sound, you all look like a bunch of hippies camping out" , so now we all have air mattresses. Then at 0430 you would have a whole platoon (31 men) pulling plugs and rolling up mattresses. it was hilarious listening to all the air escaping when we were supposed to be tactical. about 6 months later we all got foam pads to sleep on. Which lead to another issue all in itself!
