I still feel the effects of dehydration from my army days. We were being used as a test bed unit, and the new organizational makeup had some real teething problems. One was supply. There were not enough water buffalo's (water wagons) to go around, so getting resupplied with water was problematical. We didn't get water in the Texas summer heat for a day. My od green t shirt was white from the salt I had sweated. I broke out in a sweat as soon as I was able to drink some water. I have kidney stones to this day, 25 years later.
This was not uncommon for the whole year of the division restructure study. We did have some casulties due to the lack of water in the heat. I know the one canteen cup of lime koolaid I got one especially one dry day, was nectar of the gods. Ice cold, and sweet, on a terrible hot, dry Texas night. Makes you appreciate the simple things...
