Plan ahead and dont rush to the fight if after strong tanks.
+1!
Again and again I see Il-2s taking off from a base and heading directly to the approaching enemy tank and literally "hoing" it - flying almost flat & level and shooting at the tanks front armor.
Even when not getting sent quickly back to tower due to flying down a T-34's gun barrel, the chances of hurting the tank that way are almost nil.
Set up your attack! Rushing it will have the opposite effect: You will spend much more time & ammo (and often planes).
