Armies and navies in Rome II can be made up of a maximum of 20 units and must have a general or admiral to lead them. These stances are called 'Forced March' which enables an army to march further, but which will also tire out its men and reduce their fighting ability 'Defensive Stance' that enables the player to place stakes and build temporary forts 'Ambush Stance', which enable the army to remain hidden and attack the enemy with traps such as rolling balls of flaming hay and finally 'Raiding Stance' which lowers the range that the army can march but greatly lowers its upkeep cost. These stances determine many things, among them total movement points per turn or the ability to deploy traps for an ambush.
Armies and navies also have changeable stances on the campaign map.
