Development in South Africa was parallel where the SAP (police) and the military worked separately with the military retaining the conventional chassis with its suspension system (the Buffel) while the SAP developed the monocoque design used by Konchel in Rhodesia on the Leopard further (into the Casspir).
It should be noted that while Rhodesian vehicles were designed to travel on roads and tracks the South Africans developed vehicles with cross country capability to avoid roads and tracks that could be mined.
