Just played this. The Americans had a mathematical chance at game end, but there were a lot, a lot of Germans adjacent to the highway at game end. The German purchases were pretty much what others have done: group D on board 4a, group C on board 6 and group A on board 46. The armor purchases were group two and group three.
The tough nut was on board 6, where the two pillboxes set up on opposite sides of the road facing each other in 6X1 and 6Z1 with squad, MMG, squad, HMG. The pillboxes had mines on top. My opponent had his wire around the pillboxes; I wonder if it shouldn't be on top. This would not be too bad, but he had his 75L and HMG in 46Y5. This denies the use of the center highway for movement, as well as the obvious plan of putting tanks between the two pillboxes. Because of this I had to bypass the pillboxes to deal with the gun first. One of my M10s tried to fire AP into the back of one of the pillboxes, but it malfed its gun.
After a few turns my flamethrowers were able to clear the gun and hmg. I then moved infantry on top of one pillbox and cleared the other with a Sherman (but we messed up the DRM on the CH, making the attack at four down five rather than four flat). The other pillbox did not clear by game end, so that was one VC missed. There was also an armored car adjacent to the road, so that VC was missed again. I made the exit VC, and much to my surprise, much of the exit VP (and exit VP for MMC) were from prisoners.
Although it was going to be a stretch, I did have a chance on the last turn. Well-designed and a challenging play.
