There are so many variables, it's hard to be sure. The AI comes at the defender at 2.5 to 1 odds and it does apply a lot of pressure due to shear numbers. More prudent artillery usage, planned obstacle breaching and better approach routes and those numbers might be difficult to beat.

It also depends on if you are playing a stand alone game or in a campaign. In stand alone games, you can pick a force best for defending and still be realistic, where as in campaigns your core has to be more rounded for all missions. I just finished a campaign defend against the AI and my core has 31 tanks and tank destroyers and a couple of infantry companies. It's not the best force in the world to defend with. A few armor units were destroyed, but half of my remaining tanks and TDs were either immobilized or without main guns. The main causes were artillery and air strikes. Visibility was 25. Who expects air sorties with that visibility? Anyhow, I think a person would have really been able to take advantage of force not oriented to defensive missions.
