The RG-31 Medium Mine Protected Vehicle was used for command and control of clearance operations and other missions and protected soldiers from mine blasts and IED detonations. The RG-31 tactical vehicle, a product of BAE Land Systems OMC (previously Alvis OMC, and having changed hands numerous times before that) of South Africa, offered excellent ballistic and mine blast protection. The RG-31 Mine Protective Vehicle was one of the newest weapons in the countermine arsenal. The RG-31 Medium Mine Protected Vehicle (MMPV) was an armored personnel carrier meant for use both on and off-road. Capable of carrying up to a crew of 10, depending upon the version, it provided protection from small arms fire and antitank detonation. The vehicle was capable of withstanding the detonation of the equivalent of 14 kilograms of TNT under any of the vehicle's wheels or an equivalent of 7 kilograms of TNT centrally under the vehicle's body. The vehicle's basic armor could withstand impacts from 5.56x45mm rounds, while the manufacturer offered additional protection to defeat armor-piercing 7.62x51mm rounds.

The RG-31A1 (also known as the RG-31 Mk 5) was a full-time 4-wheel drive, multi-purpose 5-seat personnel carrier suitable for on-road and off-road applications with a range of 550 km. The design and construction of the vehicle was intended to provide protection for the occupants from small arms fire, land mines, and IEDs. The vehicle was accessed through a rear door. The vehicle's body consisted of an all-steel welded-armor monocoque body with V-shaped hull. The modular interior layout could be configured for armored personnel carrier, command and control, ambulance, scout vehicle, or other applications. The engine, transmission, and fuel cell were situated inside the armored hull for maximum protection. Shear-off fenders were provided for water and equipment storage. For self-protection, the vehicle was equipped with eleven gun ports for personal weapons and a single top-turret hole. On some vehicles a remote weapon station was fitted to the top of the vehicle, further improving the ability for the crew to return fire while being protected. For route clearance operations, spare tires were normally removed and additional armor added to protect air tanks and fuel lines. The RG-31A2 (also known as the RG-31 Mk 5 Extended), differed most notably in having a longer overall length. The RG-31A3 (also known as the RG-31 Mk 5 Enhanced Mobility) featured a similar hull length to the standard RG-31 Mk 5, but was fitted with a more powerful 300 horsepower engine.

In 2007, Land Systems OMC had also debuted a further improved variant, the RG-31 Mk 6. This variant featured a hull longer than the RG-31 Mk 5E and a more powerful engine than the RG-31 Mk 5EM. The vehicle hull was also widened slightly at the front and the overall hull was widened, requiring new windshield panes, similar to those on the RG-33 series, leading to some confusion between the 2 vehicle types. The vehicle front ends remained distinct.
