Italian military planners saw the need for highly mobile artillery early in the 20th Century. Accordingly, Italy began mounting anti-aircraft weapons on truck chassis prior to WWI, giving birth to the autocannone, a weapon concept that soldiered through WWI and WWII. Inspired by the German half-tracks equipped with 88mm guns, the Italians reprised the autocannone with their 90/53 guns on a heavy truck chassis. Other vehicles, some captured, were mated with a wide variety of weapons, often in the field.
