Marines and Sailors with Marine Rotational Force-Europe

Marines and Sailors with Marine Rotational Force-Europe 18.1 dig into the hillside to construct snow caves during a winter warfare training exercise at Haltdalen Training Center, Norway, April 14, 2018. More than 70 Marines and Sailors spent three weeks in the Norwegian wilderness learning cold weather survival techniques, which were taught by Norwegian Soldiers with Home Guard 12. Each service member shoveled several hundred pounds of snow and ice so every cave could accommodate four individuals. (U.S. Marine Corps photo by Gunnery Sgt. Clinton Firstbrook)
