No, you can kill a panzer or T-34 with the osti. back of the panzer, or side of the drivers compartment for the T-34. But when you DO get a hit with one, the hits look IDENTICAL to the ones you get with the Il-2. Same explotion, and the same little smoke swirl one the..... I guess they're flames....... clear.
The hits also look the same as the Yak9T, and I'd bet that they didn't use AP rounds either. Why use AP rounds with something intended for air to air work?
Come to think of it, you get the same thing when you hit an armored vehicle's tracks with the osti as well, and the U.S. 37mm, AND the german 30mm.
If the Il-2 and Hurri IID have AP rounds, we need to get the hit vizualizations changed to hit sprites.
