IActually, the problem with the game’s reality is that the King Tiger battle with batle with the M26 Pershing is impossible to shoot down.
The King Tiger used the 88mm KwK 43 L/71 anti-aircraft gun. The King Tiger had much thicker armor. The tank’s frontal armor was 185mm. This made it virtually impenetrable. The only disadvantage of the King Tiger was suffering from recurring mechanical failures due to its extreme weight.
