Another couple of other things I noticed when playing on the above mentioned map with the same three opposing forces!
Firstly, for Nod and the Soviets, a large number of infantry would gather next to the barracks and construction yards and would not be used for the entire battle. At first I thought that this was because they were protecting these two structures but this seemed a bit of overkill, and then I thought maybe it's because they could not reach my base since it was cut off. To test this I changed the battle to 'Free for All' so they would attack each other and noticed they still never used the infantry.
The second thing may not be a problem with the AI or maybe just a limitation of it. In every battle the Soviets would build a nuclear reactor to power its base, which is fine and not a problem since most people would do the same. However, in each case the reactor was an incredibly easy target since it was always on the outskirts of the base with virtually no protection. I actually had no problem taking it out in every battle with Harriers without losing a single one.
Thirdly, Soviet V3 rockets could have easily bombarded my base but they never tried doing this, the Soviets did use them on the Yuri and Nod bases when playing in the 'Free for All' mode.
Sorry, to be pointing out these AI problems (or limitations) in your fantastic mod, I know it's still work in progress and hope my feedback helps in some way and does not discourage you and your team.
