Love the one page idea, love the simplicity in the ruleset and in the army lists.
First question about melee: Would I be interpreting the rules correctly if I say that there can ever only be one unit fighting another one in melee at any one time? I'm thinking about the alternating activation together with 1" separation after a round of melee rule.
Second question about melee: Is it possible for a unit to fight more than one melee combat in one round. I'm thinking: say a human infantry unit charges an enemy cavalry unit in its activation. They separate after they determine the result of that combat. Then that enemy cavalry unit charges that same infantry unit in its activation. Again they separate after they determine the result of that combat. Then another enemy monster unit charges that same infantry unit (say the enemy monster unit clips the original infantry unit, and both units shuffle to maximise contact). Would that mean that that very same infantry unit has fought 3 times in that particular round?
