I don't remember mentioning AP ammo.
My point was that it was used in air to ground role so being listed under 'attack' in AH isn't really wrong.
...But in actual, historical use by the Soviets in World War II it was used primarily as a fighter plane and not for ground attack not busting tanks.
It is often assumed, as Krusty points out, that because it had a big gun, as did the Yak 9K with a 45mm gun, that it
must have been designed with tank busting in mind. After all, isn't is the same gun used in the tank busting IL2?
Who in there right mind would ever think to use such a large caliber gun to shoot other planes with?
