General Information
The 7.5cm Pak 40/3 L/46 Gw 38(t)r Ausf M was designed in 1941, manufactured by BMM based on the existing fully tracked Czech 38T and was in use from 1942 to 1943.
The vehicle was powered by Praga 'EPA/2' petrol powerplant producing 125 HP which could drive the vehicle on roads at up to 25 mph with a range of about 150 miles before refuelling. Its cross country performance was good providing a max speed of about 13 mph and a range of about 60 miles.
It was armed with 1 light machine gun. This version was a successful matching of a PaK 40 75mm Anti-Tank gun with the PzKpfw 38(t) chassis to create a mobile anti-tank platform

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.
