We were running a grenade range as the sapper company and we'd been out all day in full kit and it was about 100 degrees but felt much hotter. When you are in full kit you can add about another ten degrees to the feels like. So if it feels like 110 with the humidity you can add another ten (at least) to what it feels like underneath your body armor. We drunk all of our water in the first hour of us being there.
They brought us lunch, and I got a drink just assuming it was going to be water or gatorade but it was black. Then I assumed it was going to be iced tea. Took a big swig. Shit was hot coffee. NO WATER was brought. Sometimes in the Army you just sit in blind rage for a few moments at stupid things that happen and that was one of them. I don't know why, but I was so mad for about fifteen seconds that I splashed the coffee at the guy who delivered its feet, and was like "Why the f**k did you bring hot coffee when its 115 f**king degrees?" and then tossed my food in the trash, and just lived the rest of the day dehydrated and dizzy as f**k (even if you don't have liquids to drink you can still get some hydration with food). My piss was brown when I got back. I think what saved me was that about fifteen other people were shaking their heads in agreement when I had my mini breakdown and they kind of realized how stupid that choice of beverage was given the circumstance. They ALL outranked me though so I dodged a bullet there.
Squids can have coffee though, shit is nasty.
