Staff Sgt. Kyle Snape, 90th Security Forces Squadron military working dog trainer, is bitten by MWD Nemo, demonstrating the dog's capabilities during Fort D.A. Russell Days, the annual open house on F.E. Warren Air Force Base, Wyo., July 20, 2018. MWDs play an important role in securing the base by doing routine security checks and preforming tasks humans can’t do, such a bomb sniffing. The open house gives the community the opportunity to see the history behind the base and its role within the nation’s defense. (U.S. Air Force photo by Airman 1st Class Abbigayle Wagner)
