Advise needed - Campaign "Sturmgeschütz Brigade 276"

[BigDuke66]

I tried it now with a different setup:
-8x 8cm mortars
-3x StuH42
-3x Panzergrenadier Zug

The pre-planned bombardment of 8x 8cm mortars seems to have made them keep their heads down but also rise enough dirt to cover my advance. And I kept bombarding him, in the end I used all ammo up.

I also advanced in a tighter formation with the StuH on the main road and the Stugs close to the North and South.
But the real key is that the Russians counter attack as soon as the first objectives change hand, if the German player now keeps good positions he can take anything down that comes his direction including their tanks, after that he makes the final push and that's it.
Did win this time only with 11 men lost.
