The Barracks functions as a 10 bedroom house but only for Guards. Any Guards in the village will choose to move to the Barracks instead of their existing house.

When they have no other tasks, Guards may choose to train in the barracks.

Guards will use armor stands as training aids, hitting them with their swords.

If there are at least two armor stands, the Guard will also practice the Super Duper Whammy Jammy Attack.

While practicing with armor stands, Guards will slowly gain experience.
