The fan-made manual states:
A mixed army has "Courage" but not "Morale." It attacks or flees according to the normal rules, but does not join the hero (unless "Courage" is specifically set to do so).
With ALWAYS_FIGHT, it doesn't look very good that no one will flee, which, in the case of attacking weakened enemy units, will look annoying.
There's also another question that I've been wondering about for a long time:
If you place a unit on the map that has multiple stacks, depending on the difficulty and as new weeks pass, will the number of creatures increase in all stacks, or only in the one that was initially placed and to which the others were later added in the properties?
