The most famous Italian tank destroyer of the Second World War was technically not a tank destroyer, but self-propelled artillery. The Semovente da 75/18, based on the M13/40 frame, was developed to support front-line infantry, and therefore has fixed armament: a 75 mm gun in casemate. However, thanks to its low height (185 cm) and the caliber of its gun the 75/18 also had good results in anti-tank combat, fighting against British and American (but not Soviet) units. After the Armistice of 1943, the 75/18 remained in use by German forces.
