MOODY AIR FORCE BASE, Ga. -- Staff Sgt. Tory Curtis, 23rd Security Force military working dog handler, runs his MWD, Hal, through a canine obstacle course as U.S. Air Force Academy cadets look on during their base visit April 29. The canine unit gave the cadets a demonstration on how well the MWDs listen to their handlers and showed the bond between handler and canine. (U.S. Air Force photo/Airman 1st Class Benjamin Wiseman)
