17, actually. And no, I'm not nessicarily wrong. Its highly dependent on the time frame, which was unspecified.
late 1944, 1945, you're right. Early-early mid 1944, I'm right. Mid 1944, its a wash.
However, you refuse to admit that you might even potentially be wrong, yet alone that you ARE wrong, again depending on the time frame.
Fact is that a 122mm at 2000m carries less kenetic energy than a 90mm M3 at 500 yds. So, since Tiger II's could (sometimes) stand up to a 90mm at even closer than 500m, we can guarantee for a fact that Tiger II's could (again, sometimes, but still more often than with the 90mm) stand up to a 122mm at 2000m.
But no, you assume that because a 122mm caused heavy spalling, and could even crack welds at close to mid ranges, that it was also capable of doing this at long ranges consistently.
One hit isn't going to equal one kill at 2000m. Even for the KwK 43, a FAR superior gun, it isn't guaranteed to be a kill.
