What would be cool, is if like, when your unit has only say 10 hit points left he collapses and you have stretcher bearers going around picking them up and then taking them to a hospital tent where they slowly heal and then return back to the battle. But there is like a 70% percent chance of the unit dying before he heals. Would be a little more realisitic Might be a bit late to incorperate this, but maybe Part 2?
