Police Lt. Muneyuki Hirao, a police dog trainer at Hiroshima Prefectural Police Headquarters, and his K-9 search for hidden explosives during a joint training exercise at Marine Corps Air Station Iwakuni, Japan, Feb. 17, 2016. K-9s are trained on scent boxes in order to get them familiar with the different scents of various explosives. The location and types of training are changed each time to broaden the capabilities of the dogs as well as the handlers. (U.S. Marine Corps photo by Lance Cpl. Aaron Henson/Released)
