Following that match, after ProfessorHenn had to go, Feirmont and I played a 2v1 match against an easy AI.... And promptly walked over the AI.
Feirmont with normal troops and a few experimentals. Myself with an army of Experimentals.
Following that game, I played alone against another AI, with Nukes and Artillery disabled (Note that 'Artillery' in this option is defined as the Long Range Artillery building).
Both the AI and myself were UEF. I had set research to be pre-finished. All I had to do was build an army.
It took 4 hours for me to push him back off the land bridge between our bases. And another hour to finish off his forces.
Moral of the story folks.
Don't let an AI, regardless of it's difficulty, get a completely researched Tech Tree. It will produce Experimentals until you are simply outgunned.
I had to resort to a turtling crawl towards his base using the mobile artillery unit of the UEF. Even then, I had to retreat twice. He liked dropping troops behind my line....
