It was mounted in a fully rotating, electrically driven turret, and had an elevation of 20 degrees, and a depression of 10 degrees. The gun was capable of firing hollow charge, high explosive, and armour piercing rounds. The secondary armament consisted of five Breda 38 machine guns (two mounted in the hull, another two in a coaxial mount, and the fifth on top of the tank in an anti-aircraft mount.)
