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, providing maximum firepower and strategic mobility to mechanised infantry units intended to operate across the vast distances of Southern Africa. Primarily envisaged in SADF doctrine as a vehicle that could deliver mechanised infantry and supporting fire to tanks in conventional warfare, it was also anticipated that the Ratel could form the centrepiece for semi-independent battlegroups where logistics or politics precluded the use of tanks. The Ratel was a simple, economical design which helped reduce the significant logistical commitment necessary to keep heavier combat vehicles operational in undeveloped regions. It was generally regarded as an influential concept which incorporated a number of novel features, such as a mine-protected hull, an extended operating range of 1,000 kilometres, and a 20 mm autocannon fitted with what was then a unique twin-linked ammunition feed, allowing turret gunners to rapidly swap between ammunition types during combat.

The EE-11 Urutu is a Brazilian amphibious armored personnel carrier. It was based on the drive train and chassis components of the EE-9 Cascavel armored car and initially emerged as part of a project to develop an amphibious troop-carrying counterpart to that vehicle for the Brazilian Army and Marine Corps (CFN). The first pre-production models entered service with the CFN in 1973 and serial production commenced the following year. While the CFN declined to adopt the EE-11 Urutu in large numbers, the Brazilian Army was more forthcoming and purchased 223; these entered service in 1975.
