Airmen from the 191st Maintenance Squadron, huddle together to have an initial debrief after a training exercise at Selfridge Air National Guard Base, Mich., Aug. 13, 2011. The 191st MXS performed an exercise in which they simulated a KC-135 had damaged nose gear and a crane was needed to move the aircraft to a safe location for repair. After such exercises, Airmen gather for both formal and informal debriefings, to review the operation and to learn how they could improve in the future. (USAF photo by TSgt. Dan Heaton)
