If you have reached your command point limit during a mission, send out a battalion or two (with the Banner Carrier upgrade) of soldiers. Have them fight until there is only one or two men remaining in the battalions/hordes. Then, send
them back to your base, near a Healing Well for the Good side. You have just freed up several command points. Your damaged battalions can regenerate. Use this strategy to make up to three battalions of cavalry to raid your opponent with.
