The Army Arrow Counter mod is a small, quality of life, open-source mod that gives you insight into the amount of ammunition remaining in your army.

It's a small, quality of life, open-source mod that is meant to give the player information they need to make the best tactical decisions. If you were the commander of a real medieval battle, you'd be able to ask your sergeants about the ammo status, but alas, Bannerlord has no such functionality. This is the next best thing to try and provide the player with the crucial information they need to make the best tactical decisions!
