Worked out well I thought. I've tweaked some of the stats a bit and removed one of the ranged combat modifiers but the game played well and there wasn't any obvious problems.
I want to add grenades and mortars next and then start adding some of the US and German special characters as they are probably going to be difficult to balance
Once that is done I should hopefully have my West Wind German walker assembled and be able to test those rules out as well. I have the US and German AT teams ready to go as well so once the Walker is ready I can add more AT units to the US force.
