also, try ISU 152, great kubel counter
Main gun destroy/engine damage and the kubels go back to repair
Productive post:
-Zooks needs some kind of buff. I don't want them to be Carl Gustavs but i guess making them hit vehicles is too much to ask right?
-Kubel could get some kind of vehicle size increase. I remember it's something like 25%/50% f/n to hit it with a zook. So even if you "rush" zooks to deal with Kubels, you still need to hit it 3 times with a 25%-35% at most.
