We assume that the unit commanders will make the best tactical decisions for their units.
So in this AAR I have two brigades of six battalions each - a small Division. My orders are to attack, so I deploy them in column and send them off, along with attached artillery, and two units of cavalry. They proceed into contact and at this point the unit commanders are in charge (dice rolled).
Take a look!
Fun to play and many opportunities to tweak the rules to better reflect different situations. Looking forward to my next game.
