If it was not freezing cold and wet it was sweltering hot - and wet.
On very hot summer day the brass decided, that our truck had been "contaminated" with some nasty stuff, and it had to be washed down with some kind of soapwater.
As the brass was very concerned with the wellbeing of the grunts, we had to do it in a full NBC protection suit.
My rubber boots were filled with sweat after that.
Oh, those fond memories.
