Allied Auxiliaries (Cross-Faction Units)

I wasn't happy with how useless military allies were in vanilla - they rarely help you out in any meaningful way and tend to drag you into stupid wars. The smartest way to play is often to just refuse all military allliances, and that's just not super fun to me. So, inspired by the 8th Edition tabletop's Allied Armies mechanic, this mod aims to fix that by granting you limited access to the units of your military allies and vassals! Each faction will offer 14-16 unit types depending on their vanilla+DLC roster. Each are generally the shielded or armored version when possible, no slots wasted on filler crap. The basics; Making a Military Alliance or Vassalizing another faction, and constructing their clearly-labeled special faction building in a province capital (NOT minor settlements), will allow you to build some of their units. This also works in coop right from turn 1, just make the building! Based very loosely on 8e mechanics: each faction's units are split into 3 categories; Common, Rare, and Elite, each with different caps. Common includes 4 of the most iconic tier 1-2 units of a faction, like Darkshards (Shields) or Dwarf Warriors, each capped to 4 units. Rare includes 8 tier 3-4 units, each capped to 2. Not as spammable but MUCH more powerful and can make a huge difference for some factions with very limited options - Vampire Counts with Organ Guns? Elite generally include 4 tier 4-5 units, each capped to 1, though Dwarfs and Greenskins instead offer 2 units capped at 2 each. The capstones of each faction, getting access to War Mammoths, Engines of the Gods, and Steam Tanks can make a fun cornerstone to even endgame armies. Auxiliaries come with the equivalent of a generic redline (8MA/MD, 12% missile damage, 20% ammo) but DO NOT benefit from factional redlines, lord-unique skills, or most techs. The buildings are split into two sets; Order and Destruction. If you're concerned about lore friendliness, stick to the same set as your race. Otherwise, have fun.
