Picture of the Day: US Marines Go Shirtless During Winter Training with ROK Military

South Korean and U.S. marines run through a snow-covered field carrying each other over their shoulders at a mountain training center in Pyeongchang, east of Seoul, on Jan. 28, 2016. The marines from the two countries conducted the joint drill, set in extreme cold winter conditions, to enhance their combined military capability. The U.S. maintains about 28,500 troops in South Korea as a deterrent against North Korea after the 1950-53 Korean War ended in a truce, not a peace treaty. (Yonhap)
