General Information
The Sherman IVA M4A3 was a similar shape to the M4 but had a welded hull and was powered by a Ford GAA-III engine producing 500HP. The cast turret carrying the gyro stabilised 75mm Gun M3 was the same as that of the Sherman I. As with the earlier Sherman I the drive sprocket was at the front, the track went under 3 double bogie wheels onto the idler, then back over 3 return rollers. All of the 75mm armed version of this tank had glycol filled ammunition racks which were known as wet stowage they were designated as M4A3W

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.
