In this Dec. 6, 2012, photo provided by the U.S. Department of Defense, soldiers assigned to 6th Engineer Battalion use snow shoes during Arctic Light Individual Training on the Bulldog Trail in sub-zero conditions at Joint Base Elmendorf-Richardson, Alaska. ALIT is the United States Army Alaska's Cold Weather Indoctrination program. It gives all soldiers, regardless of their job, the foundation to successfully work, train, and go to war in some of the harshest environments in the world.
