If there are more than 5 armies in the Region after a Conflict then armies must be disbanded until there are 5 or fewer. To do this, follow this rule: “Have one of every army, if possible.”
No matter which type of army, start by removing 1 from whichever type has the most. If multiple armies are tied for the most, remove 1 from each of the tied types. If there are now 5 or fewer armies, then disbanding is done. If there are still more than 5, then continue disbanding until there are 5 or fewer.
