Best I've managed is an MV, and I was surprised at that! I think it was because I was able to set up a defensive perimeter after overunning all objectives by turn 4. Then it was RPG7s at point blank and assaults with satchel charges & flamethrowers to hold the Pattons off. They would have overrun me in another couple of turns - I was surprised the AI didn't "extend" the scenario.
Refreshing to make a mess of Pennsylvania Avenue!
