As someone that was in the military and went through boot camp during the summer at Fort McCellan Alabama, then did two preseason camps in college football.
When it got to a certain temp in the Military we changed how we trained and drank a lot of water. When it got to a certain temp, we took buses or cattle cars to the ranges. Reading this article, a couple of flags came up.
If this kid was struggling, he should have been taken out of the training and treated for a heat injury. I don't know, we only know what is reported and the truth will come out eventually. WTF, one water break. In football we drank water after every drill.
