Red Alert 3 RA3 modders, can you tell how make AI produce new units and assign their roles?

[Neon serpent 0]

I created many new units for my mod (mostly ships and aircraft), but computer opponent does not produce them.
I tried to correct xml files SkirmishAI and personal, writing strategies and actions with new units (for example - a rush attack with frigates and corvettes, or a raid with stealth aircraft), but it only resulted in duplicating commanders.

Can you explain how to write new units and their roles for AI?
