Sergeant Kyle Cary, a 2nd Law Enforcement Battalion military working dog-handler, jumping off the high-dive with his dog, Brandy, in the Area 5 pool at Marine Corps Base Camp Lejeune, N.C., Aug. 3, 2018. 2nd LEB practiced aggression training as part of specialized training to familiarize their dogs with water. The 2nd LEB military working dogs benefit from this particular type of training due to not being exposed to water tactics during initial training periods and become better accustomed to performing duties in atypical situations.U.S. Marine Corps/Cpl.
