Help me pick out a PZC title

[Outlaw Josey Wales]

If I remember correctly with Smolensk, you don't start with an overwhelming amount of forces, but will build up over time. It takes awhile for the German infantry to show up. But they do have a fair amount of mech forces.

If beach landings catch your fancy, Normandy has several, but the camp is 250 turns with a ton of forces and then there is the overall monster that is 750 turns with all the forces through Aug.

But as others have said, for that you are talking about, MG would be good. I think there are plenty of scenarios that you could play. I don't remember, but there may be a decent battle scenario for each of the AB drops and XXX Corps and some that combine a couple. You could always go with those first before doing the camp for the whole thing.
