U.S. Air Force Staff Sgt. Joshua Krape, 4th Operations Support Squadron survival, evasion, resistance and escape specialist, demonstrates how to quickly create a shelter using the environment and a map during a combat survival training course, June 27, 2017, at Howell Woods, Four Oaks, N.C. According to Krape, having a shelter that blends into the environment can keep downed aircrew alive when they are trapped behind enemy lines. (U.S. Air Force photo by Airman 1st Class Kenneth Boyton)
