About Barracks

Priority: High

The Barracks is your primary military training facility, directly controlling how fast you can train troops and how large your army can grow. A higher-level Barracks increases troop training speed and unlocks higher-tier soldiers, giving you a critical edge in Alliance battles and PvP.

Upgrade Tips

1Upgrade Barracks alongside your Infirmary — a larger army means more potential casualties that need healing.
2Higher Barracks levels unlock Tier 3 and T4 troops which have dramatically better combat stats.
3During Alliance events, max troop training speed from Barracks upgrades can win or lose rallies.
