campaign scenario setup help

[Ts4EVER]

Shortly before the Kampfgruppe was to be pulled out of the line for a well deserved rest, an alarming message reached the commander:
The pocket around the swamp land had been closed, but the link was weak, with the infantry holding it all but exhausted. The Russians had apparently noticed this and started a breakout attempt aimed at the weakest part of the front. Ivan is throwing the heaviest tanks he has into the attack. Your unit is to bolster the defenses and hold off the attack. Several heavy at guns are also on the way to assist you in knocking out the 50 ton monsters.
