Yeah, the random encounters seem have better AI (though I've seen flame-thrower equipped heavies set the woods on fire -- the woods they are standing in). On first play-through the AI seems sort of plausible, but you soon learn to recognize repetitive tics (such as a path they are glued to on a tight timetable) that are very easy to exploit. Also there are gaping holes in their outpost defenses, completely undefended sides, usually conveniently overlooked by hills. But this is on 'normal' difficulty. I'd expect some of that to be different on higher. The most dangerous things in the North so far are the freakin' snow leopards.
