Whats the best tactic for effective rocket attacks with IL2, against German tanks, lets say pzIV?
Realistic rocket spread, phew I have a hard time hitting anything, with 300m rocket convergence, 10sec delay.
And difficulty with rocket hitting, is with these formations of four tanks, mobile. My best results against four moving panzers, is when I use dive bombing with low alt bombs, bombing along the predicted path which the stupid ground AI drives the tanks over

With 10sec delay, it's no problem getting 1-2 tank kills this way dive bombing with longer delays, but accurate low level bombing.
Flak 88mm I prefer to kill with either high angle dive bombs, about 60deg, low alt bombs. One drop is usually good enough to kill it.
With rockets, I can also kill flak 88mm, when I make high angle rocket attack, with two salvoes of rockets, usually converging nicely on top of the gun, within maybe 10m circle of the gun itself.
It's just that rocket attacks against mobile groups, or mobile single tanks seem a lot more difficult with these crazy rocket spreads
