- This article is for the Legacy of the Void multiplayer version. For the previous expansions' multiplayer version, see Barracks (Wings of Liberty and Heart of the Swarm).
For the Korean Terran player, see BarrackS
The Barracks (Rax for short) is the infantry production building for Terran; allowing them to build Marines, Marauders, Reapers and Ghosts. It is commonly used as part of a Terran wall-in and can be lifted off the ground and landed elsewhere after it has been constructed.
In mech-based play, a Barracks will often be lifted to serve as a heavily armored scout or to spot for Siege Tanks. In bio-based play, this role will often be served by a Factory, as it is less important for production.
Heart of the Swarm
Reaper play is very different in Heart of the Swarm, with the unit being almost completely reworked. It's easier to harass using Bio, since it doesn't require a Tech Lab anymore.
- Barracks can build two types of add-ons.
- Without any add-ons, the Barracks can produce a single Marine or Reaper at one time.
