Warfare

Militant factions are divided by their mode of transport first and foremost. Those on land are sperate form those in the air or nautical warriors or those that tunnel underground. These factions can then be divided by the mode of assault the sub factions perform. This can be artillery, melee, communication, wards/distraction/illusion, mind control/ mental battles, etc. then this can be further divided by what reln the units use, or what they use to attack with. The flame dancers, lightning artillery, tidal crashers, medical units, or any number of things.
