Bustr, that's probably the same reason we don't have 24 r4m's on our Focke-Wulf's and Me262s.
They did not leave any smoke trails, the allied thought they where hit by flak, not by fighters.
The 190F8 only carried bomblet bombs on the center mount, they where to big for the wings, they either had the rockets, but more often the small bombs, the rockets where very effective when you hit, but much like the allied rockets, very hard to hit with.
In AH you can kill a Panther with the anti-tank rockets, but you have to get close, I have only managed to kill Panthers twice with them.
