Alvis FV600 family

The FV600 idea was a common chassis with whatever body the job wanted. It worked because the chassis was good: independent suspension on all six wheels, permanent drive and enough ground clearance to leave the road entirely. The engines, transmissions and brakes varied considerably between the four, which is why they look more alike than they are.

The Saracen went to Malaya, Aden, Northern Ireland, the Yom Kippur War and Sri Lanka, and was exported in hundreds — 280 to South Africa alone. The Saladin is still in service in five countries seventy years after it was designed. The Salamander served the RAF until 1978. The Stalwart carried five tonnes at 64 km/h on land and six to nine knots on water until 1993.
