A Survival Evasion Resistance and Escape student pops red smoke in anticipation of a rescue helicopter used during vectoring training March 13, 2011 at the Colville National Forest, Wash. The vector training gets students familiar with proper protocol to correctly guide a helicopter into position to safely rescue them if needed. This entails everything from authentication, to using a compass to pinpoint their heading for the pilot to be able to locate them. (U.S. Air Force Photo/Tech. Sgt. JT May III)
