The RG-31 Nyala is a 4×4 multi-purpose mine-protected armoured personnel carrier (APC) manufactured in South Africa by Land Systems OMC, a division of BAE Systems. It is based on the Mamba APC of TFM Industries. The RG-31 is built from a V-shaped all-steel welded armor monocoque hull and high suspension, typical of South African mine protected vehicles, providing excellent small-arms and mine blast protection. The vehicle is designed to resist a blast equivalent to two TM-57 anti-tank mines detonating simultaneously. The RG-31 is classified by the United States Department of Defense as a category 1 Mine Resistant Ambush Protected (MRAP) vehicle.
The vehicle accommodates a crew of 8 or 10, including the driver, depending on model. Dismounting is provided via a large rear door and two front doors.
The RG-31 has become the multi-purpose vehicle of choice of the UN and other peacekeeping and security forces. It is finding favour with non-governmental organisations requiring a vehicle with a non-aggressive appearance to protect their personnel against the threat of land mines.
