I'd have thought - These are the conditions you will be operating and this is your task - please plan what you will require to complete it - with comments like Mr Smith, perhaps more than a single water bottle would be a good idea...if anyone is screwing up.
Surely we've all done tabs, mountain climbs, etc. albeit not at the extreme level required on selection, and many have done stuff in the Gulf, in conflict and not, Cyprus up and down the hills, so why on one selection on a hot day, did three guys die of (I assume) dehydration?
Although I hear of recruits, and others, collapsing on hard phys ever now and again, but what was the overwhelming factor that made three go in one day? Were they encouraged not take extra water as it's consumption would risk a failure on a weigh-in at the end? Did they just underestimate their intake that day?
I know I'm being rather simplistic, but is there anything in the public domain that explains it, or is it simply down to 'A hot day'?
I ran up Pen-y-Fan on a fell race the day those guys died/were hospitalised. It was a bastard hot day and a couple of fell runners - normally a fairly hardy bunch - just turned around and walked off; and we were dressed in shorts and t-shirts.
I don't think it would take a genius to work out that there'd be heat casualties in those temperatures; and I'm not talking about us, I'm talking about them. We don't need any more H&S, just some common sense. I hope whoever was running the exercise had his career stopped.
