"Using privates" is a time honored military tradition. In the 70s if a unit was in the field and came under nerve agent attack, they would remain in MOPP gear until the "All Clear" was given. If the unit was isolated and could not receive an "All Clear", then the senior NCO would select the most expendable private and have him hold his breath, crack open his mask and then reseal his mask. The NCO and the medic would then watch his eyes. If they became pinpointed then they slapped him with two atropine injectors. Hopefully he would live.
Moral of the story...… never tick off your NCO or you may become "most expendable"
