Shit, RD, I work at a job outside in this heat everyday. I've seen people coming close to heat stroke on the street. Running around in full BDUs or even just long pants is killer in this weather. It's more than keeping extra water on hand, especially if people are playing airsoft (i.e. being out in the middle of nowhere). Sure I'm not breaking any new ground here, but for fucksake, I don't want to see anybody get heat stroke playing airsoft.
