The vehicle was powered by FIAT-SPA 'SPA 180' petrol powerplant producing 70 HP which could drive the vehicle on roads at up to 26 mph with a range of about 120 miles before refuelling. Its cross country performance was good providing a max speed of about 14 mph and a range of about 48 miles. It was armed with 1 light machine gun , a Breda Modello 38. Its main armament consisted of an Cannone-Mitragliera da 20/65 modello 35 (Breda) which could penetrate 21 mm of flat plate at 100 metres Armour Details Turret Front 40mm @ 10° (41mm) Side 15mm @ 15° (16mm) Rear 15mm @ 15° (16mm) Top 6mm @ 90° (6mm) Superstructure Front 30mm @ 10° (30mm) Side 15mm @ 10° (15mm) Rear 15mm @ 0° (15mm) Top 6mm @ 90° (6mm) Hull Front 30mm @ 10° (30mm) Side 15mm @ 10° (15mm) Rear 15mm @ 0° (15mm) Top 15mm @ 0° (INFmm) Armour (x)mm @ (y)° (Effective mm @ 0°) Effective Armour - Maximum 41 mm - Minimum INF mm Weapon Details Breda Modello 38 (Machine Gun) History The Breda model 38 was the Italian army standard vehicle mounted machine gun.

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.
