In this Aug. 23, 2011, photo from the Defense Video & Imagery Distribution System, Staff Sgt. Robert Bales participates in an exercise at the National Training Center at Fort Irwin, Calif. On Friday, Aug. 23, 2013, a military jury sentenced the U.S. soldier who massacred 16 Afghan civilians in 2012 to life in prison without a chance of parole. Bales pleaded guilty in June in a deal to avoid the death penalty for one of the worst atrocities of the Iraq and Afghanistan wars.
