Ordnance Q.F. 37mm Mk 1 (Anti Tank Gun)
Used both as an Anti Tank gun and as a Tank gun the 2pdr was first used by the Belgians in 1939 and the majority of the British guns were captured by the Germans at Dunkirk and given their designation of 4.0 cm Pak 192(e) or 4.0 cm Pak 154(b).
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.
