| 説明 | 180218-M-DV652-0062.Sgt. Joseph Griffin, a northern warfare training instructor with United States Army Alaska, demonstrates how to construct an arctic space heater, designed to provide warmth in arctic ten man tents at U.S. Army Northern Warfare Training Center, Alaska, Feb. 18, 2018. Marines with Combat Logistics Regiment 25 and Low Altitude Air Defense, Alpha Battery, took part in the Cold Weather Leadership Course conducted by the Army, designed to provide cold weather familiarization to ensure the units operate without sustaining cold weather injuries. This training is in preparation for Arctic Edge 18, a biennial, large-scale, joint-training exercise that prepares and tests the U.S. military’s ability to operate tactically in the extreme cold-weather conditions found in Arctic environments.
