I remember Infantry Officer Basic Course at Ft Benning in January. Once we were out in the field for two weeks with the Rangers. It rained the entire time, temps in the upper 30's low 40's. The guys from the sunny states had never been that cold and had a really hard time. It was tough, especially on the last day when we did our water survival test. In and out of the water three times, standing for a couple hours. A lot of guys ended up in the hospital, the company commander got relieved. It was defiantly an experience that for the rest of my life when I faced tough conditions I'd reflect and thought if I did that I can do this.
