During our CULP mission in South Korea, we spent a day and a half observing summer training that every ROK ROTC cadet must complete the summer before their senior year of training. When we arrived, we were greeted by a ROK Major General. We were led inside the headquarters building and watched a presentation about ROK ROTC and then our OIC gave a presentation about USA ROTC. After that we dropped our bags off at the barracks and marched to the chow hall. I think it is sufficient to say that ROK Army chow is not the most appetizing food in the world for an American: White rice with Octopus tentacle spicy sauce. Right after eating lunch, we had to PT with the ROK cadets. It was extremely hot because ROK cadets PT in their combat trousers and t-shirts and the weather was in the high 80s and extremely humid. I was sweating before we started. Although the heat was pretty rough, it was a really cool experience. After PT, the ROK cadets showered but we couldn't because we only had one set of ACUs and we had just sweated and rolled around in sand in them. We rinsed off with cold water from hoses on the outside of the barracks and then marched to a mountain where the cadets do a lot of their training. We watched cadets qualify with the K2, their standard assault rifle and had a brief introduction to the weapon. After that we walked further up the mountain and watched ROK cadets conduct their version of STX lanes. Throughout the day, all of us were sweating buckets while the ROK cadets didn't seem to sweat at all. They didn't carry canteens and I never saw a ROK cadet drink more than half a cup of water. I don't know how they don't have heat casualties all the time. We joked that they absorb their water through the humidity in the air. At the end of the day, we split into pairs and visited a specific room in the barracks for half an hour. All the cadets were really friendly and  polite. I got to disassemble a K2 and was starting to put it back together when we had to leave to go to another room. At the end of the night we all tried to go to sleep but most of us couldn't sleep well because the ROK cadets sleep on slabs of tile that are raised about a two feet above the floor and have a little mat to put over the tile. The whole night, we were all really hot because there was no air conditioning. In the morning, we found out that not only was there not air conditioning, but the floors are heated. We couldn't believe that the ROK cadet didn't think there was anything strange about heating floors in the middle of the summer when it's over 80 degrees outside. He reasoning was that they need to heat the floors during the cold winters. I guess they didn't install an off switch.
