The vehicle was powered by Renault '6-cylinder 9.5 liters' petrol powerplant producing 150 HP which could drive the vehicle on roads at up to 14 mph with a range of about 62 miles before refuelling. Its cross country performance was adequate providing a max speed of about 7 mph and a range of about 24 miles. It was armed with 2 light machine guns which were Mitrailleuse modèle 1931s. Its main armament consisted of an C.L. de 47 antichar SA-L mle1937 L/53 which could penetrate 63 mm of flat plate at 800 metres Armour Details Turret Front 45mm @ 25° (50mm) Side 40mm @ 30° (46mm) Rear 40mm @ 30° (46mm) Top 12mm @ 90° (12mm) Superstructure Front 40mm @ 20° (43mm) Side 35mm @ 0° (35mm) Rear 30mm @ 0° (30mm) Top 20mm @ 90° (20mm) Hull Front 40mm @ 20° (43mm) Side 35mm @ 0° (35mm) Rear 30mm @ 0° (30mm) Top 20mm @ 90° (20mm) Armour (x)mm @ (y)° (Effective mm @ 0°) Effective Armour - Maximum 50 mm - Minimum 20 mm

Weapon Details Mitrailleuse modèle 1931 (Machine Gun) x 2 History Designed by Lt Colonel Reibel, the FM 24/29 was developed into a heavier machine gun capable of relatively sustained fire, by giving it an extremely thick and massive barrel, to act as a heat sink.

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.
