The Ratel is a South African infantry fighting vehicle. It was the first wheeled infantry fighting vehicle to enter service worldwide and was built on a modified MAN truck chassis. The Ratel was designed in response to a South African Army specification for a light armoured vehicle suited to the demands of rapid offensives combining maximum firepower and strategic mobility. Unlike most contemporary IFVs, Ratels were not intended to fight in concert with tanks in a major conventional war, but provide strategic mobility to mechanised infantry units accustomed to operating independently across the vast distances of Southern Africa. The Ratel was a simple, economical design which helped reduce the significant logistical commitment necessary to keep heavier combat vehicles operational in undeveloped regions.
