Like the command center, the barracks is a mobile structure able to traverse great distances in order to reach new hot-zones or deployment centers.
Under the Terran Confederacy, barracks were standard structures at most bases and possessed a universal design. The Terran Dominion consider the bunkers to be a safe, comfortable staging point for marines on the field, a statement that many marines vehemently disagree with.
The deployment room is located at the entrance/exit to the barracks, a ramp leading down from the entrance. Standard protocol involves 'green lighting' deployment, a platoon/squad surging out as one as the door slides open. Weapon and equipment racks are also located here.
The barracks is one of the most essential buildings, producing 'first-tier' units. Without other buildings, the barracks can only produce marines for 50 minerals apiece. With the academy building, the firebat can be produced for 50 minerals and 25 gas. With an academy and a science facility building with an attached covert ops add-on, the ghost can be trained for 25 minerals and 75 gas. If playing the StarCraft: Brood War expansion pack, the medic is produced here at the same cost for a firebat, and same requirements (barracks and academy). The barracks itself requires 150 minerals to be built.
New barracks units arrive at the rally point by drop pod.
We have developed a new low-cost drop-pod that lets us send our infantry units straight from the Hyperion to the barracks' rally point. This technological marvel gives us the ability to reinforce instantly when far from our main base and to surprise the enemy from above.
Storing medpacks has traditionally required the advanced facilities of the tech lab. Remedius Medical Systems now offers a storage facility that can be housed in the barracks itself, eliminating the need for the tech lab when training and outfitting medics.
Protoss plasma shields have finally given us the ability to fit the tech lab and the reactor into a single structure add-on. This new add-on, known as the tech reactor, replaces the old tech lab and reactor add-ons, and allows us to train two of any unit type simultaneously.
All structures repair themselves to 50% life. All structure fires are automatically put out.
This all-in-one safety system automatically dispatches robotic drones to put out any fires and perform basic repairs on damaged structures. Although these drones are effective at doing basic repairs, they do not have a strong enough AI to perform the more delicate repairs needed to restore a structure past half life.
