This 40-second clip, taken, Jan. 17, 2020, at Big Sandy Lake on South Post at Fort McCoy, Wis., highlights a student -- a #USMarine​ -- participating in #extreme​ cold-water immersion training for Cold-Weather Operations Course (CWOC) Class 20-02. He was among 39 students who completed the course. The cold-water immersion was the last event in course training. CWOC students are trained on a variety of cold-weather subjects, including snowshoe training and skiing as well as how to use ahkio sleds and other gear. Training also focuses on terrain and weather analysis, risk management, cold-weather clothing, developing winter fighting positions in the field, camouflage and concealment, and numerous other areas that are important to know in order to survive and operate in a cold-weather environment. The training is coordinated through the Directorate of Plans, Training, Mobilization and Security at Fort McCoy.

nice back flip on a jet ski.

check out this newbie attempting to ski. He looks as if he was sitting on the toilet... the newbie was not injured and his fall just got him closer to the bar for a pint.

Skiing with friends in Italy. Great weather and loads of snow. Some crazy jumps and falls.
