The Army has been showing off its newest and most advanced vehicle - a remote-controlled armoured digger.
Each 'Terrier' costs six million pounds to build, and weighs as much as 15 transit vans.
The vehicles are driven by using a video game-style controller, which means soldiers can carry out a number of tasks a safe distance away.
Our Correspondent, Martin Dowse, has been to Bovington Camp in Dorset to see 'The Terrier' in action.
The interviewees are: Colonel Simon Hulme, Assistant Director, Military Engineering Capability; and David Bond from BAE Systems.
