Military alliance (Total War: Warhammer III)

Military alliances in Total War: Warhammer III are agreements between 2 factions, to support each other in all future wars.
==How it works==
* A military alliance must be agreed upon by both parties, to come into effect.
* Two military allies have promised that if either of them asks the other to go to war in the future, they will do so. Regardless of who started the war.
** For instance, if you have a military alliance with Faction A, and they declare war on Faction B and ask you to join, then you must join the war against Faction B or else you are breaking the alliance.
** This is different from a defensive alliance, where you only agree to help your ally if they are the one who has war declared against them.
* On that note: Unlike vassalisation, military alliance is not binding, neither party is actually forced to honour the agreement.
** However, there are severe diplomatic penalties (a loss of reliability and negative diplomatic relations penalties with the faction who was betrayed) for breaking it.
** For this reason, you should be careful about who you enter into alliances with. You may or may not wish to get dragged into other people's wars.
* Just like vassals and defensive allies, military allies can engage in War coordination to cooperate with each other. This allows things such as building Outposts to add to each other's garrisons, or even borrowing armies from one another temporarily.
