In this photo taken on Thursday, instructors rig a dummy suicide bomber to explode during the operator advance course at the U.S. Army John F. Kennedy Special Warfare Center & School at Fort Bragg, N.C. A scene of stomach-clenching gore confronted the special operations troops: The shredded remains of a suicide bomber, scattered around the checkpoint. But the blood and body are fake, like the Hollywood-style explosion that began a classroom exercise designed to teach these students to look past the grisly mess for the evidence that could lead to those who built the bomb.
