The A10 cruiser tank was designed as a highly modernized version of the A9. Compared to its predecessor, it differed mainly in the removal of the turrets in the front of the vehicle, which housed machine guns, and the strengthening of the armor, especially in the front of the turret and hull. At the same time, however, the same drive unit was retained, which, with the increase in the weight of the vehicle, meant a decrease in its characteristics compared to the A9 model. The A10 cruiser tank, like its predecessor, was not a particularly successful tank, but it was characterized by high mechanical efficiency, was reliable (also in desert conditions), and its main armament allowed it to destroy almost any German or Italian tank at the beginning of World War II. The vehicle received its baptism of fire during the fighting in France in 1940, and was later used during the fighting in Greece in 1941 and during the initial period of the North African campaign (1940-1943).
