Operation Herbstnebel
The 6th Panzer Army was the best equipped among the three German armies that participated in Operation Herbstnebel.’ Among many things, it had a battalion of the huge 70-ton Königstiger tanks, which, with its 88mm KwK43 L/71 Kampfwagenkanone had an almost unmatched firepower. A Königstiger could knock out a Sherman frontally at a distance of up to two miles, whilst its own frontal armor was almost invulnerable to the fire of a Sherman at basically any distance.
