An explosion within 4 mtr of infantry in the open will cause 99% casualties - lethal.
An explosion within 9 mtr of infantry in the open will cause > 66% casualties and could damage some AFV's.
An explosion within 22 mtr of infantry in the open will cause 33% casualties.
The blast effect of this shell exploding within 1 mtr of an armoured vehicle will penetrate 7 mm of the tank armour including the roof.

About Penetration Figures

All penetration figures in this database are calculated to a common standard based on German WWII testing criteria (complete penetration with functioning fuze). This allows direct comparison between all nations' guns.

Original national test figures would be higher for some nations due to different criteria:

German: 1.00? (baseline - strictest)
British: 1.02? (slightly looser)
American: 1.05? (50% mass through plate)
Soviet: 1.10? (75% mass through plate)

For example, a Soviet gun showing 159mm here would be published as ~175mm in Soviet documents, and a German gun showing 120mm would be published as 120mm in German documents. The 159mm figure is directly comparable to the German 120mm - the Soviet gun really was more powerful.

National Testing Standards
German:	1.00? - Complete penetration, fuze functions (strictest)
British:	1.02? - Complete penetration
American:	1.05? - 50% of shell mass through plate
Soviet:	1.10? - 75% of shell mass through plate
All database figures are normalized to German standard for direct comparison. Multiply by the factor above to see original national test figures.

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.
