I wondered what to do for a larger force. Either four or five square would form a larger unit of identical troops. With four they could themselves form into a larger square of forty by forty men. And they could form a triangle in the same way as hundreds. They could also deploy in squares at each corner of a formation. On the other hand five squares would give them reserves although they might be out of place in a battle in their own camp or another defensive situation.
I thought of a model for a larger Legion structure based on a game I used to play in Age of Empires II called Chinese warfare. There are eight players in a land based game with a population limit of 150 or 200. This allows you to have truly vast armies and fight battles where the rules should support unit versus unit combat rather than man against man combat. My preferred infantry formation was based on a combined formation of 10 Elite Chu ko nu, 10 Pikemen and 10 Elite Skirmishers. This formed an anti all arms unit with troops capable of fighting against infantry, cavalry or archers. Added on were field artillery in the form of four or five heavy scorpions and light cavalry to prevent an enemy approaching the formation unnoticed and making a surprise attack. A unit of heavy cavalry would also have been useful to attack artillery who infantry are very vulnerable to. A similar structure could be used with a Realm Legion with three groups of squares, each a different troop type and several extra units like artillery and cavalry. Scouts should be placed on the corners of the formation to give them the greatest line of sight around the infantry. The scale of the game was so huge you could field several of these divisions. It would have been good if you could fight units against units in battles that size. The scouts are very important for giving the unit awareness.
