It adds extra debug information to the combat replay, one of those being the orders given to each squad (as a number). I don't have the game in front of me at the moment, but you can spot a cheater that way if you were motivated enough. You'd have to create a test game to see what the numbers for the standard orders are. The "Attack Commander" command would show up as a different number.

I believe I had the vampires in question on attack rearmost. I'm guessing the troops (or at least some of them) were on guard commander? I didn't check the turn too carefully before I had to leave this AM.
