I'm reading Koskimaki's Battered Bastards of Bastogne. He mentions the 463 Parachute Artillery Battalion and its small 75 mm pack howitzers knocking out 8 out of 10 German tanks at Bastogne. They used hollow charge ammunition to perform the task. I never heard of such a thing for those little guns (we had one in the SF Presidio that was used ceremonial purposes). Can anyone tell me more about the ammunition? I know about hollow charges, but for a 75 mm howitizer?
