The Barracks is the Allies' infantry production structure.
The Allied Barracks is the structure that allows a commander to train basic and advanced Allied infantry. It also allows for the construction of basic Allied defenses. The more Barracks a commander has on the field, the faster infantry are trained.
Like all Barracks, the Allied Barracks is one of three buildings that are available by default once the Allied Construction Yard is deployed. Therefore, unlike in the vanilla Red Alert 2 and Yuri's Revenge, it is encouraged to build this structure first, so that the commander can churn out Attack Dogs for reconnaissance, Engineers for capturing of vital tech structures, and GIs for offense and garrisoning of civilian structures as soon as possible, and build appropriate defenses (like the Pillbox) when needed.
The Allied Barracks trains the following infantry:
Allies' basic and starting infantry
Armed with a machine pistol that is decent against infantry
Able to garrison civilian structures
Can deploy to use a more powerful machine gun
Allies' anti-armor/anti-air infantry
Armed with a missile launcher that is effective against vehicles and aircraft
Able to garrison civilian structures, but loses ability to attack aircraft
Can deploy to increase its weapon's range and accuracy, and become immune to vehicle trampling
Allies' reconnaissance and anti-infantry animal
Its teeth can maul infantry instantly
Detects disguised units
Allies' essential field support infantry
Able to capture enemy buildings, tech buildings and empty vehicles
