In Dawn of Titans the Barracks allows you to train troops to fight for you in campaigns and against other players.
Increasing its level increases the number of troops you can add to your training queue. This allows for more troops to be trained simultaneously. You can also instantly complete entire training queues with gems.
There are relics you can add to your barracks to reduce the training time of your troops and other relics that can reduce the food cost.
At the start of Dawn of Titans you can train three human troops: Militia, Archers and Spearmen. As you advance through the game you can unlock: Grenadiers, Pikemen, Goliaths and Panthers.
The table below has the build cost for each upgrade level. It also shows the build time, buildings required and the number of units you can add to a training queue.
