Mike Stewart, GORUCK cadre member, sprays participants of the GORUCK Light Challenge with water from a fire hose July 12, 2014, at Mountain Home Air Force Base, Idaho. The only relief participants had from scorching 90 degree heat of the July sun was from being blasted by fire hoses while performing flutter kicks on the pavement.
