Firefighters with the Fort McCoy Directorate of Emergency Services Fire Department's diving team practice a surface ice rescue scenario at a frozen lake in Wisconsin, US.

The team practice reportedly took place at Big Sandy Lake, Fort McCoy, on January 11.

Several firefighters with the team took their turn getting in a suit, strapping an air tank and full-face mask, and diving into the depths of the lake under the ice on Fort McCoy’s South Post.

The divers were covering depths of up to 15 feet or more, completing several types of rescue scenarios under the guidance of fellow firefighters.

Divers took turns going in and out of the same hole that was cut in the ice.

Each diver was tethered with a connecting line that included a communications connection.
