It seems you can't disengage from combat as you could in Gold. There should be some chance to disengage, especially for cavalry and skirmishers.
There could be a morale cost to represent disorder from the maneuver and to discourage micromanagement to get successive charge bonuses. Maybe units with a guerrilla trait or skill would have less or no penalty.
The old TacOps alllwed you to set ROE (rules of engagement) for each unit. I think I've seen the concept elsewhere, too. For example, avoid engagement or defend to the death. It was too complicated, but ROE would reduce the need for babysitting. It would give archers and javelineers a fighting chance.
