A Soldier takes the plunge into a hole cut into an ice-covered Big Sandy Lake as part of cold-water immersion training for Class 19-01 of the Cold-Weather Operations Course on Dec. 13, 2018, at Fort McCoy, Wis. The Soldier was one of 38 students in the course. In addition to cold-water immersion training, students were trained on a variety of cold-weather subjects, including skiing and snowshoe training as well as how to use ahkio sleds and other gear. Training also focused 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. (U.S. Army Photo by Scott T. Sturkol, Public Affairs Office, Fort McCoy, Wis.)
