A Division is an autonomous body of troops during a battle, part of a Battle Line. Regardless of their Type, all Combat Units in a Division fight together and are considered a single target for purposes of enemy Attacks.

Divisions are used only in Field Battle, and only for the Archery or Frontline Battle Lines. A Battle Line's Divisions are always one Center and two Flanks.

In the Archery Line the different types of Archers are proportionally deployed across the three Divisions. Destroying a player's Archery Line Division with your Melee troops grants the opportunity for a Flanking Attack against his remaining Frontline Divisions.

In the Frontline, all Melee units are assigned to a Division according their Priority Deployment. After any preliminary attacks by Ranged units, Frontline Division enter Melee combat with the corresponding enemy Frontline Division: Flank against Flank, Center against Center. Destroying a player's Frontline Division grants your Melee troops the opportunity to advance and attack his Archery Division behind.

If all troops in a Frontline Division are killed, they're immediately replaced by the Reserve. For all intents and purposes the Reserve becomes that Frontline Division until the end of the Field Battle, or until destroyed.
