Six-wheel-drive
Six-wheel drive (6WD or 6×6) is an all-wheel drive drivetrain configuration of three axles with at least two wheels on each axle capable of being driven simultaneously by the vehicle's engine. Unlike four-wheel drive drivetrains, the configuration is largely confined to heavy-duty off-road and military vehicles, such as all-terrain vehicles, armored vehicles, and prime movers. When such a vehicle only has six wheels by definition all are driven. When it has ten – with two pairs of ganged "dual" wheels on each rear axle as on a GMC CCKW – all are also driven but the 6×6 designation remains. For most military applications where traction/mobility are considered more important than payload capability, single wheels on each axle (often referred to as super singles) are the norm. Heavy hauler and ballast tractor 6×6s have had a long history as prime movers both in the military (as tank transports and artillery tractors), and commercially in logging and heavy equipm ...

Alvis Stalwart
The Stalwart, formally classified by the British Army as Truck, High Mobility Load Carrier (HMLC), 5 Ton, 6 x 6, Alvis/Stalwart and informally known by servicemen as the Stolly, and by former RCT as the Stally, is a highly mobile amphibious military truck. Built by Alvis Cars between 1963 and 1971, these vehicles served with the British Army from 1964 until 1993. History Alvis had great success with the FV603 Saracen armoured personnel carrier, being produced from 1952. The Saracen having permanent 6 wheel drive, and independent parallel wishbone links and torsion bar suspension on each wheel station. Alvis then used the same suspension and drive methods to develop the FV601 Saladin armoured car, and the Salamander airfield crash tender. Following the success of those vehicles, Alvis then decided to start a private venture of an off-road truck, capable of carrying 5 tons and being highly mobile. Using the hull and cab of the Salamander, Alvis created the 'Camion' for the mil ...

Alvis Salamander
The Alvis Salamander is a six-wheel drive airport crash tender with off-road capabilities, developed in 1956. It shares the same common Alvis six-wheel-drive chassis and other components with the FV 601 Saladin armoured car and FV 603 Saracen armoured personnel carrier. In turn it led to the FV 620 Stalwart load carrier which was derived from the Salamander. The vehicle is powered by a Rolls-Royce B81 straight-eight engine producing at 4000 RPM and of torque at 2500 RPM. Fire fighting equipment was provided by The Pyrene Company Limited. It could produce 7,500 gallons of foam per minute and carried a crew of 6. 125 Salamanders were built and used in the Royal Air Force (as the Alvis Salamander/Pyrene Mark 6) and the Royal Canadian Air Force. From the late 1970s on they were replaced by vehicles like the Thornycroft Nubian Pyrene Mark 7.

All-terrain Vehicles
An all-terrain vehicle (ATV), also known as a light utility vehicle (LUV), a quad bike, or simply a quad, as defined by the American National Standards Institute (ANSI); is a vehicle that travels on low-pressure tires, with a seat that is straddled by the operator, along with handlebars for steering control. As the name implies, it is designed to handle a wider variety of terrain than most other vehicles. Although it is a street-legal vehicle in some countries, it is not street-legal within most states, territories and provinces of Australia, the United States or Canada. By the current ANSI definition, ATVs are intended for use by a single operator, although some companies have developed ATVs intended for use by the operator and one passenger. These ATVs are referred to as tandem ATVs. The rider sits on and operates these vehicles like a motorcycle, but the extra wheels give more stability at slower speeds. Although most are equipped with three or four wheels, six-wheel mod ...

Pinzgauer High Mobility All-Terrain Vehicle
The Pinzgauer is a family of high-mobility all-terrain 4WD (4×4) and 6WD (6×6) military utility vehicles. The vehicle was originally developed in the late 1960s and manufactured by Steyr-Daimler-Puch of Graz, Austria, and was named after the Pinzgauer, an Austrian breed of cattle. They were most recently manufactured at Guildford in Surrey, England by BAE Systems Land & Armaments. It was popular amongst military buyers, and continued in production there throughout the rest of the century. In 2000 the rights were sold to Automotive Technik Ltd (ATL) in the UK. ATL was acquired by Stewart & Stevenson Services, Inc. in 2005. In May 2006, Stewart & Stevenson became a subsidiary of the aerospace and defence group Armor Holdings, Inc. In 2007 Armor Holdings was acquired by BAE Systems plc, who discontinued UK production of the Pinzgauer, which was proving to be vulnerable to mines and improvised explosive devices in Afghanistan. Production ceased around 2009. Development wor ...
