====== Barracks ======

The Barracks is the ultimate protection for your colony. Each Barracks can hold multiple Barracks Towers within its structure. A Barracks Tower employs and houses one Guard per level. Official Barracks contain 4 Towers for a total of 20 Guards, though custom structures may vary. Placing Barracks near homes and workplaces boosts colonist happiness. :contentReference[oaicite:1]{index=1}
