The Warrior Barracks is a Bronze Age Military Building. It is where a player can train the Warrior, the heavy unit of the age. It is the fourth unlocked military building of the age. In order to construct the Warrior Barracks, a player needs to have unlocked the Phalanx technology.
It very strongly recommended to build the Warrior Barracks to counter the Spearfighter, the light unit of the age. The Spearfighter will be very common in this age. The Warrior is powerful even into the Iron Age. However, the Warrior should be replaced with the Legionnaire Barracks once it is unlocked.
The warrior is most effective against light units. It also receives additional defense when standing on plains.
