The Pig was based on a Unimog 2.5 chassis and made in the Selous Scouts work shops. They were created to lead their external raids into Mozambique so as to provide ambush protection to the lead vehicles. They were not mine protected. Mounted with a 20mm canon and a number of MAG it was a lethal combination. The 20mm Unimog base vehicles I used was the Unimog UR-416 made by Model Miniatures of France. 1/72 scale ref: MM-RO49.
