Here is a photo showing how to deploy a division. One part of the division's chariots is screening the forward area. Behind them are two archer units whose job it is to support with tremendous fire power the line infantry. The heavy line infantry is in column and will deploy into line. A second part of the divisional chariots hang back to support the division (right). I recommend giving each unit a unit leader. This will give them an additional plus 1 morale and melee bonus. Again if you do not think that you like all the modifiers on the Q.R.S. drop what you don't like. I trust your ability to interpret history.
Left is the division in column (bottom of photo). I am not showing the archers or chariots here. Just the heavy foot portion of the division. Here is the division deployed for battle. To the front are the chariots. Ready to skirmish forward. Hopefully they can soften up the enemy. To the rear is the heavy infantry of the division ready to advance. In support of the line infantry are two specific units of archers (shooters) ready to deliver volleys of arrows on the enemy. These are shooters not fighters and will evade if necessary. They can also screen the line infantry. The idea was to shoot the enemy up to the point of disorder and then charge in with the line infantry. This system kept the enemy at bay for centuries.
