"Soldiers – none. But the training is stock standard for volunteer firefighters here in Oz. It is also quite well-known in walking circles – try walking in 40 C heat with bright sun and limited water."
I'm very familiar with those conditions. Last week it got up to 109*F here in town. We see temps in the triple digits for weeks at a time and it's not uncommon to get above 110* for a week or so:

Some of the heat casualties I mentioned earlier where in much warmer places like Ft. Benning, GA and the jungles of Panama.
I actually wrote a lengthier response but figure it's a waste of time here and the conversation is just going to devolve into a whip out contest. I'm going to stick with what I know works and you do the same. I will say that comparing a walk in 104*F weather compared to the conditions a soldier is subjected to is mildly hilarious so thanks for that! In fairness, Firefighters do have a tough/hot job so that certainly is comparable somewhat.
OP,
Did I mention that Nuun tablets are not only tasty, but fizzy too!
