An Army is a group of ordinary units that move and fight together. To form an army, you must build the Army unit and then 'load' other units into it. You can load up to three units, though the Pentagon increases this limit to four, if you have built it. Building an Army Armies can be built in cities that have the Military Academy or a Leader in them. But you must have at least four cities for every army you create. In Battle An army uses one, some, or all its internal units to fight a battle, depending upon the course of the fight. Spotting An army can "see" up to two squares away, due to its intrinsic scouts.
