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 the Troubles' Operation Banner in Northern Ireland, as well as for its role in the South African government's enforcement of apartheid.
