They stated that both the Russian 100mm & 122mm high velocity AP rounds penetrated its frontal plate & front turret. But I really don't care, Germans can have the King Tiger if they like but I really don't think it's what's needed the most. The only 2 tank maps I play are Orel and BDJ which are both Kursk scenarios and are both German teamstack Vunderlands because Russians have no "heavies" (either in armor or firepower) to compete. No SU-152 no SU-122 no KV-1E. Another side benefit of adding for instance the KV-1E would be that now the Tiger could be featured in 1942 scenarios with less protest on the Russian side if they had the "good" KV. But I still say SU-152 would be the best bet for "bang for your buck" because it was the earliest available tank capable of destroying Tigers & Panthers and can be used for Kursk scenarios all the way until the end of the war.This article on battlefield.ru has been thrown around the forum for the past year. It proves 1 thing. NOTHING! Pounding the hell out of an empty tank with 100 and 50 pound HE shells and APBC rounds will eventually cause fractures and spalling.
From looking at the photos the only thing that looked like it penetrated was the Tiger II's own 88mm gun.
