From Italy during World War II to Korea in the 1950s and Afghanistan in the 2000s, mountaineering has long been a necessary skill for U.S. service members to operate in mountainous terrain. The Defense Department has a few schools that train students on mountaineering, but its main training center is the Army Mountain Warfare School near Jericho, Vermont. Its instructors are the best of the best. (Video by Staff Sgt. Eugene Oliver)
