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

An NBC attack is not in cold weather only. It could occur in any weather, any temperature, anywhere. That means that the military trains with MOP gear in all weather, all temperatures. Loved it when we did it in Alaska. Hated it when we did it in Iraq at the height of summer on the sands.

Your buddy can whine and complain and go talk to the IG all he likes. He has no case and the IG will laugh at him and should tell him to soldier up.

If he has to fight for real in a CBRN environment in an equatorial zone in the summer, I'm sure he can contact the Opfor IG.

He needs to watch Generation Kill. That mini series is a fairly accurate depiction. He may even notice that during the initial push, the Marines are in MOPP 2. Even General Mattis is in MOPP 2 on the bridge while trearing a new one into his Colonel.

Appreciate the feedback now I’m going to tell him to quit being a b***. Drink the cool aid mf.

Have no idea about today, but used to be the Army posts posted a WBGT temp and at certain levels the post had ways to wear uniform. First level was unblouse boots, then pull shirt tail out ( for young troops we used to tuck ours in our trousers), take shirt off, and as it went up proscribed rest periods, well you get the idea. At some level,I think after boots unbloused and shirt tail out, tee shirt, no M-17.

It is difficult to do the job, but it must be done. You can't pick when you need to do it (so you train in all conditions).

I spent a lot of time in MOPP gear during Desert Storm. Afterwards, I participated in training exercises where we even had to sleep in MOPP 4! I've done Rapid Runway Recovery in July in Florida in MOPP 4, and Air Base Ground Defense Training in MOPP in the Mojave Desert as a member of a Civil Engineering Squadron. If a bunch of Air Force guys can handle it without crying to the IG, Chaplain, First Sergeant, or our mommas, an infantryman ought to be able to. Heck, half the guys in the squadron wanted to know when we would get to do it again, lol. Tell him to learn to enjoy the suck and soldier up. Good luck in your career, and may you never be surrounded by W.I.M.P.s - Weak, Incompetent, Military Personnel.

Heat Categories would mindfully set restrictions on conducting training in MOPP gear especially for extended periods of time

When I was skippering EEUPAC, our primary sandbox mission was wide area decon. The trick there was time management lest heat exhaustion took an asset offline much longer than normal rotation. The stuff we used for decon was very nasty in itself (super chlorinated HTH). Even when you do everything right, efficiency and stamina declines rapidly as you're humping these application hoses around. It was a 20 minute decon for yourself; longer if you couldn't help. We'd have about 5 pound water loss per rotation. Cycling for days in MOPP 4 will pull you down. Beer never tasted as good as it did when we came offline.

Is he being a b** or is it a valid concern? Everyone is not in the same physical shape to be conducting runs in MOP gear right after a period of time where PT/Gym access was not available. My question if I was the SPC would be where is the risk assessment for the particular training with gear on. If there is not a risk assessment I would have a chat with the CO because if someone has a heat stroke he will be answering to someone.
