General Information
The Carro Armato M14/41 Medium Tank based on the existing fully tracked M13/40 and was in use from 1940.
The vehicle was powered by FIAT-SPA 'SPA 8 TB M41' diesel powerplant producing 145 HP which could drive the vehicle on roads at up to 21 mph with a range of about 120 miles before refuelling. Its cross country performance was good providing a max speed of about 11 mph and a range of about 48 miles.
It was armed with 2 light machine guns. Its main armament consisted of an Cannone contracarro da 47/35 M35 L/40 which could penetrate 83 mm of flat plate at 100 metres

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.
