Jason, I think you should do a scenario pack covering the fighting of Uranus. I don't know if this is what you are already planning but think it would be a great idea to have some historical scenario's covering that operation.
I love George's scenario's I love the fact that they are huge. Plus throwing my two cents into what you were discussing; I think the way he has it setup for the Germans with APC's is ideal for them. For instance I am currently playing (and thoroughly enjoying) Piper's race for Belgrad.
Spolier
My tanks smashed through the Russian road block with the aid of the "air strike" and continued on down the road to look for other tanks, guns or any other hard target. All the while two companies of infantry along with the cannon platoon and the two companies APC's cleared the little village of Russian infantry.
Well just as my tanks finnished clearing all the visible enemy tanks and guns in the town down the road my infantry finnished mopping up the Russian infantry in the first village. Then my inf embarked into their APC's and started blazing down the road to fall in right behind their tanks escort.
I couldn't have done this if I had to hold my tanks up waiting for the inf to complete their task.
