Master Sgt. Rudy Parsons, a pararescueman in the Kentucky Air National Guard’s 123rd Special Tactics Squadron, searches debris fields with Callie, his search-and-rescue dog, in Cookeville, Tenn., March 3, 2020. Parsons and Callie searched for survivors of the multiple tornadoes that hit middle Tennessee earlier that morning, claiming 24 lives. Parsons and Callie — the only certified search-and-rescue dog in the Department of Defense — covered approximate one square mile in five hours. The Dutch shepherd is able to clear rubble piles in minutes using her keen sense of smell, saving hours or days over traditional search-and-rescue methods. (Courtesy Photo)
