Seems like koifish_koifish has it. Been there-Done that, (except not the pink skivees), but flying out of a dead sleep, head for a good place to defend our position and to protect my buddies who were doing the same thing to protect me. When the leads-a-flyin what matters is your there fightin back.
My guess is the guys in full gear were on duty. Commin out of the jungle soaked to the bone, skin half rotten off your feet, you really don't want your 1st sleep in days to be in full gear.
Come-on now, if someone breaks into your home, are you gonna get dressed before you blow their head off. I doubt it. My wife and I sleep nekid, (sorry for the visual), but at home I'm blowin their head off clothed or nekid.
As far as the pink, well glad it wasn't me in the pic, but my guess is the 2 guys fighting next to him really didn't give a crap at the time what he was wearing.
Don't really understand Jets last comment though.
