Modern warfare requires the support of a robust supply infrastructure and a fleet of effective vehicles to keep troops on the move and well-supplied. For almost 40 years and throughout the Cold War era, the British Army relied on the 4-ton 4x4 General Service Truck to fulfil this role. The undisputed load-lugging champion of the Army and a true workhorse of Britain’s armed forces, these incredibly rugged and reliable vehicles initially used multifuel engines but these were later replaced with more economical diesel units. With more than 50,000 produced, they were adapted to perform a multitude of different roles. Always in the background, these vehicles were unquestionably the backbone of the British Army.
