According to Wikipedia: "The Mamba is a South African armoured personnel carrier that offers protection against small arms fire and land mines. The vehicle, which uses a Unimog chassis and is powered by a Mercedes Benz engine, is suited for rough terrain and can carry up to 10 passengers plus the driver. It has been used by a number of countries as well as peacekeeping forces of the United Nations, and the improved Mk2 and Mk3 versions are in service with the South African military. A new Mamba version has been designed and built by N4 Trucks (Pty) Ltd, in their Pretoria Factory in South Africa and marketed Globally by Osprea Logistics as the Mamba Mk5 and deployed by African Union peacekeepers in Somalia. It is offered in two variants, one built on the Magirius air cooled drive train and the other on an Iveco Eurocargo drive train in water cooled configuration. It is also used in Iraq by private security contractors. Several variants have been developed from the Mamba. Recently blast tested by the Pretoria based Council for Scientific and Industrial Research, (the CSIR) the Mamba Mk 5 defeated a 10 kg explosive blast under its hull. The Mk 5 survived a blast test of 14 kg of explosive beneath its wheels in earlier tests."
