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 153 mm of flat plate at 100 metres .
The M10A1 was based on a modified Sherman Hull with thinner armour and a more powerful gun, the power for the M10A1 was supplied by a 454HP Ford petrol engine.
The turret was manually rotated, so was not as fast to rotate as other models. | |

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.
