The path chosen was that of a low-profile open hull with a semi-fixed gun, similar to the layout of the wartime Alecto.

The small hull could accommodate only a crew of two, which in turn required an autoloader, particularly for the heavy armament and ammunition in mind.

[7] This was only a boilerplate example; it was unarmoured and the armour layout design had not been completed and the body of relatively high and vertical plates is unlikely to have been the shape or the material used for a final example.

The vehicle chosen was the Rhino, a six-wheeled skid-steered experimental chassis, powered by a Rolls-Royce Meteorite engine.

[8] Drivers were instructed to drive in pursuit of fixed and moving targets and to track them with a simple windscreen-mounted sight.

All of the weapons were to be externally mounted to keep the internal hull dimensions as low as possible, however, only the gun option was considered in any real depth.

The autoloaders and their ammunition were carried in armoured boxes above the hull, with the reaction nozzles of the recoilless rifle protruding behind.
