I Tried to Join Finland's Elite Arctic Military Unit (impossible)

We traveled to Finnish Lapland and joined the Arctic Forces for a three-day survival training exercise in temperatures below -30°C. We learned to manage our clothing and equipment, ski through the wilderness, build a shelter, make fire and water, and protect ourselves from frostbite. After a painful first day and a cold night outdoors, we woke up exhausted and continued dealing with numb hands, feet and other injuries.
