Soldiers felt the chill of ice cold water when they plunged 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.

There were 38 students in the course who had the cold-water immersion training.

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.

Located in the heart of the upper Midwest, Fort McCoy is the only U.S. Army installation in Wisconsin. The installation has provided support and facilities for the field and classroom training of more than 100,000 military personnel from all services each year since 1984.
