It’s pretty well known that Navy SEALs need to be able to survive in a number of different temperatures and climates. A cold weather survival course is yet another part of basic Navy SEALs training, as it will give each SEAL the ability to stick it out through any cold weather environment they may find themselves in. When deposited in a cold weather environment, SEAL recruits will need to survive in the conditions for 3 weeks. This freezing portion of their training is one of the last exercises they will be put through and it normally takes place in Alaska.
Small boats will deliver the recruits to the coastal waters of their destination. Wearing bulky dry suits, the SEAL recruits will then need to jump into those waters and swim to land. They will be carrying all of the equipment that they need with them, including climbing equipment. After these recruits reach the land, they will be forced to climb the mountains to reach their destination.
This is not the end of their cold weather survival training, however. While the gear will give them protection against the severe chill of the water, ice, and wind, any Navy SEAL must be able to survive without this gear. This is why SEALs are forced to break through the ice and submerge themselves in the icy water for up to 4 minutes without their dry suits. This single act pushes SEAL recruits to their absolute limits and only after surviving this task will these men be able to finally call themselves SEALs.
