A firefighter wearing a full diving suit and related equipment dives into an open hole in the ice Feb. 6, 2019, at Big Sandy Lake on South Post at Fort McCoy, Wis. About a dozen firefighters with the Directorate of Emergency Services Fire Department practiced ice diving as part of the Fort McCoy dive team. Overall, the firefighters completed four days of training related to ice diving that also included classroom time and practice at the pool at Rumpel Fitness Center. Fort McCoy built the dive team capability eight years ago and the team has responded to real-world emergencies, including recently to an emergency in Sparta, Wis. (U.S. Army Photo by Scott T.
