The Humber Pig is a lightly armoured truck used by the British Army from the 1950s until the early 1990s. The Pig saw service with the Royal Ulster Constabulary (RUC) from the late 1958 until early 1970. The Pig became particularly well known from its presence on the streets of Northern Ireland during the worst of the Troubles.
The Humber Pig is based on the FV1600 series of four wheel drive 1-ton payload trucks manufactured for the British Army by Rootes from 1952 to 1955. The Pig FV1611 is the armoured variant of FV1601 CT Truck and the FV1612 the armoured version of the FV1602 CT FFW Truck. Originally designed to fulfil many roles with RAC, RA, RE, RS, Infantry. The armoured body was fitted to fulfil the need for an armoured carrier until the Alvis Saracen could be delivered in numbers. The armoured bodies were produced by J.Sankey as well as the Royal Ordnance Factories . Of 3,700 Humber trucks some 1,700 Pigs were produced 
Twenty prototype Pigs FV1609A (no armoured rear roof) entered troop trials in 1956. When these trials ended ten were issued to the RUC in October 1958. In 1960 the RUC Pigs were upgraded with a rear roof to emulate the FV1611 that was then in production The truck chassis proved ideal for urban internal security duties, and ended up serving longer than the larger, heavier Saracens that were intended to replace them.
As the Troubles in Northern Ireland escalated during the 1970s, some 487 Army Pigs were further modified with additional internal and external armour during the period Sept 1972 to July 1973. These were referred to as Mark II vehicles.The last of the Mark II Pigs were removed from service in the early 1990s.
