I've just done my first CS drills in the chamber and "shit the bed" that stuff's nasty, much to my delight I've got three more drills to go; I can barely contain myself!!
Call it what you will; taking off your respirator in the testing facility, name rank number and making the corpral laugh as you become the dribbling snot monster before he lets you out.
I believe the next is changing filters in the chamber then eating/drinking drills and i'm not sure of the last.
they come from behind you, over your shoulders, cross over and tie up in front of you?
If you have your suit like that while you're defecating you'll have an uncomfortable time of it later...
P.S. Just wait until you're on tacex.... 3 I think. You spend 24 hours in your respirator. Lovely stuff. Fair bit of running around in your rocket pack, plenty of sweat.

As I finished my NBC Instructors course, there was a platoon [don't remember the Regiment], put into sealed marques under a concentration of CS for 72hrs. They had to eat sleep and crap under those conditions, all I can say is you would have to be careful wiping your arse.
