General Information
The Carro Armato M11/39 Medium Tank was designed in 1937 and was in use from 1939 to 1944.
The vehicle was powered by FIAT-SPA '8T V-8 diesel' diesel powerplant producing 105 HP which could drive the vehicle on roads at up to 21 mph with a range of about 0 miles before refuelling. Its cross country performance was good providing a max speed of about 11 mph and a range of about 0 miles.
It was armed with 2 light machine guns which were Breda Modello 38s. Its main armament consisted of an Cannone contracarro da 37/32 which could penetrate 48 mm of flat plate at 100 metres
The vehicle was powered by a Fiat diesel engine of 105hp the front drive sprockets took the track under eight road wheels on two bogies, round the rear idler and back via three return rollers.
The 37mm gun was hull mounted with the turret holding the twin machine guns, but this design was shown to be less effective than a turret mounted main armament.

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.
