U.S. Army Spc. Anthony Boyakin, of Salt Lake City, a rifleman with 1st Squadron, 3rd Cavalry Regiment, points to places on a map where he noticed possible improvised explosive devices in an obstacle course of shipping containers Dec. 10, 2013. The course was set up to test performance enhancement skills, particularly memory skills, learned during a ten-hour course taught by master resilience trainers. Soldiers were sent through a maze of conexes that had different photos taped to them inside and out, and with other obstacles like trip wires and possible improvised explosive devices scattered throughout the area. They were asked to match the photos in charts and mark the danger elements on maps once they returned to the starting point. (U.S. Army photo by Sgt. Ken Scar, 7th Mobile Public Affairs Detachment)
