In addition to division and template Spam, the AI likes to fill up theaters of war that are nowhere near the front lines and/or clog the front lines. I'd like to propose a way to improve their behavior:
- When the nation is not at war, nor being justified upon, its default deployment of troops is garrison mode, not front lines. This will hopefully tell the AI to cap its divisions when garrisoning a state is fulfilled, and also prevent them from needlessly filling out a long border (looking at you, Canada/USA!). Nations that have border forts will also be able to keep their borders secure by this method.
- When a nation is at war, or is being justified on, it can switch to using frontlines.
- If a nation shares a border with a nation that has a similar ideology, and is not at war with it, then the border provinces will be garrisoned, not frontlines- currently, if democratic USA forms its own faction then democratic Canada in the Allies still feels like it has to line its common border with the USA using divisions that IRL were in Europe.
- If two nations in separate factions are fighting the same enemy (Allies/Comintern, Axis/Greater East Asian Co-Prosperity Sphere, etc.) and share a border, they will garrison it rather than put in front lines. For instance, if Belgium goes Communist and joins the Comintern, then once Germany declares war on both it and France, it'll put frontlines against Germany and garrisons against France. If Germany is justifying war on Belgium, but not France, then it'll put frontlines on both countries (as it did IRL).
- If 2 nations have a pact of non-aggression, they cannot put frontlines on each other's borders, only garrisons (NF allows them to cheat, as in the case of breaking the Molotov-Ribbentrop Pact).
