Tank busting aircraft

These are basically tac bombers. If we had attackers, which were just tac bombers that are better against tanks. Or kind of like Mech and Moto infantry branch off from infantry, attackers branch off from tac bombers at around, say, lvl 2.

Yes, that would be about right. Tank busting aircraft started entering service around 1942 IIRC.

Well the best tank busters were fighter-bombers like the P-47 Thunderbolt, fighter-bombers haven't made an appearance here sadly, in fact interceptors would be the opponent of such aircraft.
