The Humber FV1611 "Pig" was a small armoured personnel carrier used by the British Army since the 1950's. It was retired from frontline service in the late 1960's. When the conflict in Ulster erupted, the mothballed vehicles were re-activated and used to patrol the roads of Northern Ireland.
Wikipedia has more information about the original.
This item consists of five models on a sprue.
As separate parts, the sprue also has five turrets of the Ferret scout car / Shorland vehicle that was sometimes added to Humber Pigs used in Northern Ireland. Buyers will have to add the turret's MG barrel from a piece of wire.
The model is designed for "Detail" type materials, some detail is lost when printed in "Strong flexible".
