PETERSON AIR FORCE BASE, Colo. – Tech. Sgt. Robert Montano, 16th Space Control Squadron intelligence specialist, and Lt. Col. Richard Sumrall, 21st Aeromedical Squadron flight surgeon, work with their teammates to complete the “elephant roll” as part of the Team Cohesion Challenge at the base Fitness Center, Aug. 29, 2015. The challenges require teammates to work together to complete them, exhausting them physically and mentally. The event was held at Peterson for the first time and will be coming back next year for even more fun and team-building. (U.S. Air Force photo by Airman 1st Class Rose Gudex)
