Maintain armies

Groups
As long as you are not in a battle you can add your soldiers to groups. Usually you have the following group orders: soldier->unit->army, but one soldier can be in two groups at the same time. You could as an example have your soldiers sort into type and their ->stance(see below) at the same time. You can give your custom groups different levels and say if your commands should override the lower level commands or if the lower level commands should override the higher level commands. As an example: You have a single soldier you want to use to execute a suicide commando therefore he belongs to the group of the suicide commando which let us assume the player created and set it to level 1, but the soldier belongs at the same time to the group of spearman the player created. This group is level 2. Now he wants the spearman group to attack the walls but at the same time he wants his suicide commando to execute their orders and lit the fire of Orthanc. Therefore he makes the suicide group attack, and then his spearman, but he chooses the higher level should not overwrite the lower level orders. Suddenly the player recognizes he needs his suicide commando spearman to fight at the wall, too. Therefore he sets the spearman again to attack but this time chooses higher level should override lower level orders. The player can create all the groups customized with a different name and level which allows for better control of the army.

Stances
Before battle you can give your groups order how to behave during battle. If you choose "Charge" stance because time is important or you want your cavalry to immediately charge, they will run forth as the battle has loaded. Unless you do not catch up to them, they will be out of the players control. If you choose "Attack" stance the group will move forward in normal speed unless you give them different orders. "Normal" stance will make the group await your commands and "Defensive" stance will make the group hold their ground. For example spearman would lower their spears to defend but not move at all unless you give different commands.

Dividing armies
You can divide your armies by selecting groups and making them a different army, but every army needs a general. You can make every soldier a general(one per army is the maximum though).
