A free mod for Mount & Blade II: Bannerlord, by Basileus ThresherMaw.

Army Compositions is a mod for the game Mount & Blade II: Bannerlord. It allows you to create an army composition, which is an idea of the kind of troops that a particular country may wish to have in its army.

The advantage of this mod is that leads the AI into creating your ideal composition.

It is important to understand that there’s no guarantee that your army will be composed in a certain way because there are several other factors being considered, such as what recruits are available, the amount of money available to purchase the desired upgrade, and other unpredictable factors.

This will work with any mod that changes the vanilla troop trees.
