One thing I'm not clear on is AI captains (I apologize if I somehow missed this in the rules). I've seen some references to them--suggesting they will also be tracked and gain experience. I notice they are on the spreadsheet. Do we need to assign names to them? Do we just pick any AI captain for the opposition before playing the scenario, or select one randomly, or?

Also, did I see somewhere that some of our captains are supposed to start with abilities, or did I imagine that? If the former, how do they get chosen and assigned?
