Yeah, excellent post. I agree that education is another key element in preventing it in new people, but we forget a lot about experienced people who may have taken a break.
Only thing I can think of that wasn't mentioned is hot temperature outside (you mentioned heat, but not this kind). Most military people who get rhabdo are in basic training settings or outside in hot environments (usually also dehydration is a contributor). Here's a good article about it in the military though: http://afhsc.army.mil/msmr_pdfs/2008/v15_n02.pdf
