U.S. Air Force Staff Sgt. Roberto Matos stands his ground as he waits for Tech. Sgt. Pedro Guerrero to give Britta, a military working dog, the order to attack in a controlled water aggression exercise at Hurlburt Field, Fla., July 14. The goal of water aggression training is to allow the dogs to become more comfortable working in a variety of environments.
