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 2 mtr of an armoured vehicle will penetrate 12 mm of the tank armour including the roof. 15cm Gr 39 Hl (HEAT High Explosive Anti-Tank) 150mm 38Kg 460M/Sec Quoted Penetration 185mm @ 0mtr/0° Range(Mtr) 100 200 400 800 1200 1600 2000 2400 Flight Time(Secs) 0.22 0.44 0.9 1.86 2.88 3.96 5.1 6.29 Penetration(mm@30°) 185 185 185 185 185 185 185 185 Penetration(mm@0°) 185 185 185 185 185 185 185 185 Hit Probability(%) 98 98 92 68 37 15 3 3 Vehicles in our database using this gun Vehicle Name Common Name   SdKfz 165 15cm PzfH 18 Gw III/IV Hummel (Bumble Bee)

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.
