Bunker Busting and armor

[Kuriltai]

so I realize this problem might relate to the limitations of the Soviets at the time.

I think you hit the nail on the head here.Its not that the bunkers are to tough,Russian armor units are just too small to have a lot of punch.
You just have to be patient and go one at a time.Pick on the ones in clear terrain if possible.Its been a while and I might be wrong,but I think the 18/24/36 gun 152mm units were the key.Get your 76mm AT up to give a hand.
When you do assault,make sure the defender can retreat out of the hex.After you have taken one bunker use Isolation to help roll up the next IF you have to widen the breach.


You should try to get off Omaha beach if you want some spectacular bunkers...
