AI ground unit questions

I am currently trying to create some single missions with AI ground units. They fight with each other but seem to only use their main armament.

Also, how do you get them to fire multiple shots with their auto cannons and/or MGs? Examples include the Gepard, BMP, and Bradley.
Mind that I am using both behavior trees and triggers to make them work.

—and a side question if anyone knows, is it possible to get the AI to use stabilizers?

I can post the mission BLK if asked, although I am still developing it at the time being.

Thanks in advance
