After picking up the mod for the first time, I took it out for a test drive and found the AI to be lively and responsive, but there's a big bug. AI soldiers under my command sometimes slow down to a walking shuffle and maintain a snail's pace outside of combat for lengthy periods. This obviously undermines their ability to fight. Repeatedly ordering them to move or regroup does not fix the pace, nor does telling them to stand. They simply follow at turtle's pace.
I have not tested whether the issue is related to combat, but I think they were slightly sluggish at the march in the introduction before contact, then slowed down again at first contact, and finally slowed to a crawl after clearing Molos. Additionally, they were mobile as usual /during/ the Molos fight.
