Soldiers in MOPP 4 may lose how much water per hour through perspiration?

Explanation:
In MOPP 4, the protective gear creates a hot, humid, and restrictive environment that makes cooling by evaporation harder, so the body sweats more to try to regulate temperature. That leads to a water loss of roughly a quart per hour, and it can be even higher with activity. Half a quart or a pint would underestimate the typical loss in this setup, while two quarts is higher than the usual rate though possible during very intense exertion. The standard expectation is about a quart or more per hour, highlighting why staying hydrated is crucial when wearing MOPP 4 gear.
