" King, a two-year combat veteran sentry dog in Vietnam, gets a rewarding word from his handler, Sgt Paul F. Esser, New Orleans, a security police dog handler at Binh Thuy AB after the K-9 signed his Air Force Home Times News Release form with an inked paw. The 632nd Combat Support Group at Binh Thuy is the first unit to provide publicity to the dogs' hometowns to keep  the family that donated the dog to the Air Force and local towns people informed on what their sentry dog is doing.
