As the title says, this tiny mod just adds a garrison to Ma Teng's unique building since I feel it's pretty dumb getting unique garrison buildings without any units at all.
The file is in movie type, so you just need to drop it into your Total War THREE KINGDOMS/data folder and it'll work. Once the workshop version is up I recommend removing it.
Compatible with savegames, feel free to add or remove it whenever you like.

I also tried changing it up a bit to include his Quiang units, but there have been a lot of changes to the file structure concerning that an I couldn't get it working yet,
might try again once the workshop is availible.
