In the final of the UK tournament, a team of naval engineers from Portsmouth (Destroyers) and a bunch of estate agents from Surrey (Hot Property) built tanks that can pass over the rough terrain and shoot predetermined targets. Destroyers built a 6-wheel drive tank, Hot Property built tread-driven tank.

In challenge day, the tank from Destroyers was able to finish the course with a broken turret. Hot Property's tank, however, was high-centred when driving over a uphill slope. The tread failed to push the tank across the slope and the team failed to finish the race.
