Paratroopers assigned to U.S. Army Alaska's 1st Battalion, 501st Infantry Regiment, 4th Brigade Combat Team (Airborne), 25th Infantry Division, run through smoke to mask their movements while assaulting an objective at the Joint Readiness Training Center's Peason Ridge on Fort Polk, La., Feb. 13, 2016. The 4-25th BCT and the Airborne Task Force Soldiers, like all U.S. Army Alaska units, train to survive, operate, fight and win in extreme cold weather and high-altitude environments. They have also proven just as effective in warmer climates. Alaska's strategic location allows our airborne forces to get boots on the ground anywhere in the Pacific. (Photo by Staff Sgt.
