Forget it Blizzard:
The Ju-87G in Il-2 sucks big time:
- you can only penetrate the lightest of tanks (T34s are a no-no), this is either due to Il-2's simplistic armor system, or due to the fact that the Bk3.7 is modeled without tungsten core ammunition or a combination of both
- IRL the gun was sighted slightly below the "flight axis", so you could fire without running that thing into the ground. This is not present in Il-2.
- finally, but this is from "what I heard", the gun (being a FLAK originally) had a much higher ROF than what it has in-game
Overall it's not very satisfying to fly imo.
