Played that scenario in the ASL Ring tourny against Lionel Colin. It's a good one / fun.
His trick was to move the Russian infantry first, wait for me to fire, which meant that I could not go for a PF, move the tanks behind to prevent routing, then break the Germans with assault fire. My at start force was almost completely destroyed.
He went for the bridge and the rowhouse and won those. I missed the fact that the reinforcements can come on from both the top and bottom of the map so I did not put a Stug / squad on the bridge which would have helped.
The other trick was to HIP the German officers alone with their PF and wait for a tank to drive past. Gives the German more units to hold the line.
Deployment. I was playing Francois Boudrenghien and I had deployed 8 morale squads on the attack. His attitude was that if he deployed on the attack those half squads were as good as dead. So he deployed his worst troops - probably not conscripts though as they have a lower movement.
On the defense. If you want to hold that stone building and survive the shots without breaking - an 8 morale half squad is the best thing for that job?
Many thanks for another fun episode
