|—Age of Empires II description|
Tactics and placement
As the Barracks is the first military building that enables a player to create military units it is highly important to have at least one as soon as the player can afford it in order to defend themselves. Having a Barracks early in the game is important even if the player does not intend to use infantry units (unless they are Khmer), because it is prerequisite to build Archery Ranges and Stables.
The Barracks is a vital building when performing early game rushes like the Dark Age rush and Feudal Age infantry rush. Also placing Barracks close to an enemy's base gives the player an edge to cut off distances for the troops as they can be created near to the opponent and attack more effectively since infantry units trained there move rather slowly (except for Eagle Warriors). When playing defensively the Barracks should be placed within fortifications in order to produce support units that can deal with many siege units, many cavalry units, and trash units.
In the Goths' case they must use their Barracks extensively for offensive and defensive purposes as their Barracks' work extremely fast, enabling them to mass infantry at an incredibly high rate. Defensively, Goths should always substitute fortifications with just Barracks as they don't have access to Stone Walls and Guard Towers.

|“||Weapons were made and stored and soldiers drilled in the barracks. During the late Middle Ages, the barracks was incorporated within a castle complex. It became also the part of the castle where professional soldiers lived, ready to help defend the castle or maintain order in the surrounding countryside.||”|
