Your greatest victory and worst defeat

[Mustang]

I remember that one, it was too hard for me. I eventually did complete the campaign. Frankfurt was actually pretty easy, though- I dumped smoke right on top of my positions, so the enemy couldn't see me at all! The key was to have an armor-heavy core with a lot of light artillery to lay down smoke. The northern flanking movement is more of a threat, but in close terrain your Abrams have a better chance at ambushing the enemy. Eventually I did complete the campaign, but only by cheating a lot on the last few missions. It was a well-designed campaign, at least. It's more fun to match wits with a good scenario designer's plan than to just massacre hordes of incompetent AI.
