Witham Army Yard is a military storage facility in Lincolnshire that also sells ex military equipment. Jeremy, Richard, and James visited the yard to find vehicles to use for their demolition challenge. Whilst there, the presenters tested a Saxon, a Willys Jeep, and a Gazelle Helicopter from the 70's. Also, they found Land Rovers, a Harrier Jump Jet, and a Stormer tank. Eventually, the presenters found their equipment for the challenge. Richard chose a FV434 armoured tank, James a FV180 CET (Combat Engineering Tractor), and Jeremy an Armtrac 400.
