The Infirmary can be upgraded with 80 supplies and 2 power. These traits require 5 days to be removed and take longer if a soldier has multiple negative traits. Book soldiers in the infirmary to treat negative traits they may have picked up from the battlefield like Fatigue. Staff an engineer here to double the process of healing which is a good strategy. This room speeds up the healing process of your troops. The build priority of the Infirmary is medium unless you are playing with Iron Man enabled.
