Can his +3 cohesion bonus be used to raise a units leadership value above 9 ?
O.k, so sooner or later he will end-up in combat.
What is his defence value? Chariot plus light armour = 4 perhaps ?
Is he a superior fighter ?
Is he a formed unit ? Can he be charged at by skirmishers ? Can he counter-charge ?
Does he have open-order movement restrictions or is he generally unrestricted except that he cannot enter certain terrain features?
