How to unlock the Patched Up achievement in Battle Brothers - Definitive Guide
This is very easy to do. When you have injured men after a battle, visit a settlement on the map that has a Temple (most have). Click on the temple, select an injured unit and heal it. This costs gold depending on the type of injury (having around 300 gold should be enough). This will not fully heal the injury, but reduce the time to fully heal.
