Here is something that likely no one wants to do: jump into ice cold water.
While these U.S. Marines are jumping into what is probably the coldest water there is, you can hear soldiers reminding those in the water to keep breathing. As you can imagining, jumping into water that cold can cause a body to go into shock or get hypothermia very quickly. The Norwegians are a little more used to this, and had a good laugh at the American troops struggling through the exercise.
Though it’s hoped that these Marines never have to go through something like this in a real scenario, it’s good to know they’ll be ready if that sort of situation arises.
