The FV603 Saracen is a six-wheeled armoured personnel carrier designed and produced by Alvis from 1952 to 1976. It has been used by a variety of operators around the world and is still in use in secondary roles in some countries. The Saracen became a recognisable vehicle as a result of its part in Operation Banner in Northern Ireland as well as for its role in the South African government's enforcement of apartheid.

The FV601 Saladin is a six-wheeled armoured car developed by Crossley Motors and later manufactured by Alvis. Designed in 1954, it replaced the AEC Armoured Car in service with the British Army from 1958 onward. The vehicle weighed 11 tonnes, offered a top speed of 72 km/h, and had a crew of three. Saladins were noted for their excellent performance in desert conditions, and found favour with a number of Middle Eastern armies accordingly. They were armed with a 76 mm low-pressure rifled gun which fired the same ammunition as that mounted on the FV101 Scorpion.
