I did play Americans, but in the scenario we were playing it was harder for them. It was only 6 turns and there were a number of victory hexes (mostly key towns/villages) the Americans have to hold. It's those first couple days when the Americans were very much on the short end of it. The other guy was pointing out which hexes I needed to hold in order to control the road nets to prevent a German breakout. That's the crux of the game, controlling the roads. If the Germans can break a few powerful units into the rear areas, they have an excellent chance of winning.
It's a fascinating game. I've played it 4-5 times and I'd play it more. It really does take some time to master and I am nowhere near that point.
