Classic Military Vehicles. The First World War provided the impetus for self-powered Military Vehicles to become a vital component of all Armed Forces. Initially all types of civilian vehicles were commandeered and pressed into service. An example was the use of both British and French buses and taxis used to transport troops to the fighting front. It soon became apparent that purpose built vehicles would better suit Military requirements, manufacture's were quick to adapt suitable chassis's to suit needs as they appeared. Political instability during the 1930's resulted in rapid rearming. Modern fighting forces required more versatile vehicles. Development of all types of vehicles such as multiple wheel drive and amphibious types resulted in the vast range of purpose built vehicles used by all Armed Forces throughout the Second World War. By the end of that conflict the variety of vehicles in use included the minute Paratroopers motorcycle, the Jeep, Amphibious Troop Transport's, Heavy Artillery Tractors, and a vast number of different types of tracked vehicles.
