That illustration of yours that states projectile: 100mm/L52 APBC, target King Tiger hull and then shows the green part. That side is bugged as it seems.
What illustration? I dont see any illustration stating king tiger was penetrated at 1000m...
Lt. Wolfgang Kloth of the 2nd Panzer Div. commented that German crews quickly realized that the IS-2 had to first level the gun downward to reload the cannon, then reacquire the target each time to fire.
I have absolutely no idea where this myth came from that the gun had to be levelled to 0 degrees to reload. This is completely false. It's accuracy was not "piss poor" and was just as accurate as KWK 43.
This is a fact and Germans used that to their advantage.
It wasn´t about the total kill claim, but the ability of the Tiger II to defeat IS-2s.
Kill claims are unreliable. They are not matched with allied records and cant be trusted.
"During the first engagements in early 1944 the IS-2s showed an unexpectedly high amount of losses, especially against the smaller german 7,5cm guns of StuG and Panzer IV aswell as the similar 7,5cm Pak. In many tests and trials of fire made by the design offices, the cause was found in the unfavorable stepped shape of the frontal armor. this was 60mm thick at an inclination of 18° flat and then stepped up at the drivers hatch to 120mm."
How stugs and PIVs were able to defeat 120mm of armor is beyond me....
The shot would get deflected down at the drivers hatch into the 60mm strong armor.
