you do know that I am talking about killing panther/panzer in il2. and that from the alt, hitting on back/side is not really any different since the targets are both about the same size. So I would not really be more accurate on the panther, than i am on the panzer.

There are still differences in your attack angle, speeds, distance, projectile into target velocity, things of that nature.
Then there's the vehicle's armor, slope, thickness.
I don't know the specifics, but it's complicated as heck in terms of coding and getting it all to work.
