I'd like to see too a minimum unit number per squad, depending on unit type.

This to avoid strange tactics like the most backward archer to prevent the rout of all your mages and SCs, or to scatter troops as decoy for enemy troops or arrows in single man squad.
In a battle troops go in regiments. So on let's say you could take in account something like "size", and a regiment should have size X, or morale, because Militia need to be mobbed, meanwhile Elites could go in battle in smaller number.
