His life had a big change after Will's presence because Will found he did extremely well in sniffing tests. Will thought Buster had a special talent and decided to let him become a member of RAF police working dogs. Buster began working with Flt Sgt Barrow in 2007, and the pair was sent to Afghanistan's deadly Helmand province. There, Buster saved countless lives by sniffing out explosive devices (IEDs), as well as weapons. He joined his comrades repeatedly on foot patrols hunting Taliban terrorists and tracking down bombs. He also acted as a useful diplomatic tool, due to his friendly approach to local children. The RAF soon had a long train of children in tow, as Buster drew in his crowd and entertained them.

　　After his glittering service with the RAF, Buster retired in 2011, and died in 2015 at the age of 13 at the home of his handler, in Lincolnshire where he had been enjoying retirement with his handler Will, his wife Tracy and their two dogs who will inherit their father's career.

Over the course of his career, Buster is thought to have saved more than 1,000 lives. He also helped patrol British bases and searched vehicles at check points, and upon retirement was made the official RAF Police mascot (吉祥物). Buster's brave exploits were even documented in Flt Sgt
