Well, the main armament knockout rate should be increased, because I know that in WWII, for example, artillery HE would often knock out tank FC systems. This is really an important part of a battle, even at batallion level, and it isn't represented enough. But you're right about just disabling the main gun, even if the modern tanks would realistically have a backup FC system.

And I don't see how it's micro-detailed. Creating a 10% chance that a tank's FC rating will be halved when its hit would take up maybe a few lines of code. But I'm not complaining, increasing the main armament disable rate be good enough also.
