Light improvised fighting vehicles date back to the first use of automobiles, and to the horse-drawn tachankas mounting machine guns in eastern Europe and Russia. At the Bombardment of Papeete during World War I, the French armed several Ford trucks with 37 mm guns to bolster their defense of the city. During the Spanish Civil War, field guns were fixed to lorries to act as improvised self-propelled guns, while improvised armoured cars were constructed by attaching steel plates to trucks. During World War II, various British and Commonwealth units, including the Long Range Desert Group (LRDG), the No. 1 Demolition Squadron or 'PPA' (Popski's Private Army), and the Special Air Service (SAS) were noted for their exploits in the deserts of Egypt, Libya and Chad using unarmored motor vehicles, often fitted with machine guns. Examples of LRDG vehicles include the Chevrolet WB 30 cwt Patrol Truck and the Willys MB Jeep.
