The vehicle was powered by Fiat 'SPA I6 petrol' petrol powerplant producing 120 HP which could drive the vehicle on roads at up to 47 mph with a range of about 250 miles before refuelling. Its cross country performance was good providing a max speed of about 23 mph and a range of about 112 miles. It was armed with 2 light machine guns which were Breda Modello 38s. Its main armament consisted of an Cannone contracarro da 47/32 M32 L/32 which could penetrate 43 mm of flat plate at 800 metres Armour Details Turret Front 19mm @ 15° (20mm) Side 9mm @ 15° (9mm) Rear 9mm @ 15° (9mm) Top 6mm @ 90° (6mm) Superstructure Front 9mm @ 45° (13mm) Side 9mm @ 30° (10mm) Rear 9mm @ 30° (10mm) Top 6mm @ 80° (6mm) Hull Front 9mm @ 45° (13mm) Side 9mm @ 30° (10mm) Rear 9mm @ 30° (10mm) Top 6mm @ 80° (6mm) Armour (x)mm @ (y)° (Effective mm @ 0°) Effective Armour - Maximum 20 mm - Minimum 6 mm Weapon Details Breda Modello 38 History The Breda model 38 was the Italian army standard vehicle mounted machine gun.

An explosion within 6 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's. An explosion within 15 mtr of infantry in the open will cause 33% casualties. The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 1 mm of the tank armour including the roof.

Hit probability is based on a static 2 x 2.4 metre panel at 0 degrees(vertical) at the range specified.

The data that has been used to create these records has come from Wikipedia, The Lone Sentry, The Bundes Archive and numerous books and websites that have provided the detailed information that has not been available anywhere else. The information we use to calculate the penetration tables, flight times and the hit probability comes from the Gun Calibre, the Shell Mass(Kg) and the muzzle velocity, plus range reductions to allow for gravity and wind resistance. This calculation originally came from a pre-war Krupp calculation which has been modified, and seems to fit the actual test results.
