Is there an Army Regulation that has anything to do with MOP gear being worn in certain climates?

I advise him to go immediately. It will be hilarious. Obviously never been to NTC. You could spend 14 days in MOPP2. January or July. How about those OIF 1 guys in 2003? Should have cancelled the invasion until it was cool enough.

Now I will say that Commanders are responsible for physical preparation of soldiers to function in the environment, supporting hydration, and monitoring work/rest cycles to protect soldiers.

He can call IG all he wants. IG will laugh at him.
There are these things called Training Outline and Evaluations (TO&E) for every task that we train on. On these TO&Es it specifies under what conditions the training should be conducted, CBRN conditions is definitely listed.

I get it the heat and mop gear sucks. But the only rules for mop gear are the levels and when you need to wear it. Has nothing to do with heat because gas doesn’t give a shit how hot it is. But the gas mask does have a drinking tube so put ice water in the canteen lmao
