Air Force Staff Sgt. Vance Streeter, 210th Rescue Squadron aerial gunner, constructs a door plug for his shelter Feb. 21, 2013, Eielson Air Force Base, Alaska. The plug, when set properly, prevents the cold from entering the shelter and can help keep the internal warmth at a level well above outdoor temperatures.
