I heard several cadets were actually hospitalized due to heat attacks. That is why I asked.
From the Commandant's (BG Rapp) Facebook page:
I know that parents of new cadets and yearlings training here at West Point are concerned with the very hot temps and high humidity. We are very cognizant of the impacts of this heat wave and taking many precautions. Intake of both water and food is being emphasized; training is being modified in task, uniform, and duration; and the chain of command and medics are constantly checking the new cadets. We are on it!
The new cadets are in good hands.
Even though that statement was made over two weeks ago, it still counts for today.
If a Cadet had a heart attack, the first person notified would have been their parent, I wouldn't worry about INTERNET rumors.
