Hello Furchtlosundtrew,
Such a long name:) I would agree with your comments for the most, as I should not send messages when I drink. However I still mostly stand by my comments from most of response.
I believe that the team for Strategic Command Battlefront games mostly do a good job in reflecting the real war. These are real problems that the Germans encountered. No different than any modern war going back to the US civil war where RR heads are key along with supply. These are problems the Germans encountered along the way where it just was not strategy, nor supply or wear and tear but a lot of factors.
Try cutting the supply to these points or other. Been so long that I played but also played PBEM and won as the Central Powers and believe possible. Open to game if you like?
Regards,
