A U.S. 10th Mountain Division Solder uses a rope to climb a rocky cliff, 1943 or 1944. He is wearing a helmet and field jacket. An orderly camp is visible in the valley below. Although the notion of operating and moving in a mountainous environment seems very simple at first glance, the soldiers realized that many of the instructors were instilling a sense of sagacious perfection in all tasks. "When you have Soldiers' lives hooked into a rope system that you built, there is no such thing as 'this should hold'," said First Lieutenant Torrey Crossman. It also reinforced the notion that Soldiers should train as they fight. Soldiers who proved adept at tying knots in the barracks would struggle once they had to do so on the mountain with a full load of equipment and clothing affecting their performance.
