The Vickers Mk.11 Viper is an unusual vehicle. It is referred as a border patrol vehicle or long-range patrol vehicle. Basically this unique machine is a wheeled fire support vehicle, capable of carrying infantry squad of dismounted troops, and with a range of reconnaissance vehicle. It was designed for the changing defense requirements of the 1990s. A prototype of the Vickers Mk.11 was built after three Timoney Mk.8 (
CM31) prototypes. It seems that it evolved from the Vickers Valkyr. Only one prototype of the Mk.11 was built when the project was stopped.
