The FIAT SPA S37 Autoprotetto (“self-protected”) was developed in 1941 on the chassis of the FIAT SPA TL37 light artillery tractor deployed in Libya and renowned for its excellent cross-country capabilities. After some trials by FIAT, the Regio Esercito (Italian Royal Army) ordered 150 vehicles in 1942. This lightly armored vehicle was used primarily for police and law enforcement missions, especially against partisans in the occupied Balkans. Designer M Bergman
