General Information
The Antitank SP76mm M10 was designed in 1942, manufactured by General Motors based on the existing fully tracked M4 Sherman and was in use from 1942 to 1945.
The vehicle was powered by General Motors '6046 twin' diesel powerplant producing 375 HP which could drive the vehicle on roads at up to 30 mph with a range of about 322 miles before refuelling. Its cross country performance was good providing a max speed of about 20 mph and a range of about 128 miles.
It was armed with 1 large machine gun consisting of 0.5 inch Browning Machine Gun M2 Its main armament consisted of a 3 in Gun M7 L/53 which could penetrate 142 mm of flat plate at 200 metres .
This was the American M10 as built, and supplied on a Lend Lease basis.
The turret was manually rotated and was open, so was not as fast to rotate as other models, and suffered from grenade and mortar attacks. Initially there was no provision for indirect fire, but this was resolved in later models and retrofitted.

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.
