I was landing in Normandy and really liked how the Petards creamed the Germans. I did some looking up tfor the Petard Mortar which is weapon number 43 for Britian. I think its numbers might be a bit wrong because the dustbin it fires is 230mm not 290mm and carries 40 lbs of explosive. It gets HE penetration of 30, HE Kill of 53 and warhead 15. I looked for something to compare and found UK weapon 180 the 120 pound bomb with 32.5 lbs of TNT gets HE penetration of 2, HE Kill of 21 and warhead 15. Or the UK weapon 181 250 lb bomb with 68 lbs of tnt has HE penetration of 4, HE Kill of 34 and warhead 22
Im guessing the 30 penetration is because it is a HESH? But I think maybe the Petard HE Kill is maybe to high?
