Of my 205 kills this tour:
41 was achieved in a Bf109G-10.
39 was achieved in an IL-2(!)
Since I've exclusively used IL-2 for anti-GV sorties, out of those 39 kills in the IL-2 effectively 14 were Panzers and 10 were Ostwinds. Of the many IL-2 sorties, I am quite confident I survived through almost all of them.
Of course, I've attacked GVs in all sorts of other aircrafts through many tours, and I have yet to find such distinct aircraft for knocking GVs out of the game. I think it means all the more because I'm an average pilot.
IL-2 is the most ideal platform for knocking GVs down for most of the average people out there. There is no doubt about this.
Since there was rarely enough time for a Rook plane to catch enough alt these past few months, all my anti-Ostie attacks started hastily at low altitudes.. average 3000 feet, 4000 feet at maximum.
The key is using the 6 bombs to your maximum advantage. There is rarely enough time or altitude for the IL-2 to go through a precision drop in dive-bombing style. So I've practiced low-alt shallow angle bombing with the drop delay set to 0.10. This drops the 6 bombs in a consecutive line with the impact circles each overlapping about half of each other. Quite useful feature in knocking out GVs.
When done right, most of the times the bombs will either knockout the 37mms or make the engine smoke, or detrack an IL-2 and immobilize it - in any case making it harder for the Ostie driver to shoot at incoming target.
