00:01Welcome to Ushuaia, the city famously known as the end of the world.
00:05But for U.S. Marines and Argentine forces, this isn't a vacation spot.
00:09It's a frozen classroom.
00:11Located less than 700 miles from Antarctica, these mountains offer the perfect, brutal conditions for modern warfare training.
00:18They aren't just climbing ice walls for fitness.
00:20They are sharing critical survival techniques to master technical climbing in sub-zero environments.
00:25The goal is simple, adapt to the worst weather on Earth now so they remain combat effective anywhere.
00:31If you can survive here, you can survive anything.
