Once placed, a barracks will show the next group of soldiers; so the 1st barracks zone placed will say Barrack 1, 2nd zone Barracks 2 etc. Any soldiers listed in that group will live in and guard that area. It is good practice to place a Barracks at the opening to your dungeon. This way any mobs exiting will face a professional force. Placing beds and decorations will increase your soldier’s happiness.
NOTE: Even though a soldier will sleep in their barracks they will still require a personal room.
A Barracks zone requires at least a 5x5 tiled zone.
