Terran is the StarCraft II race whose main base begins as a Command Center.
The Command Center is the Terran headquarters structure. It trains SCVs, stores gathered resources, and serves as the starting base in standard Terran games. It can later be upgraded to an Orbital Command or Planetary Fortress, giving Terran players different economic or defensive options.
Protoss players begin with a Nexus, while Zerg players begin with a Hatchery. These three headquarters structures reflect each race’s different approach to economy and expansion.
Terran Command Centers can also lift off and move through the air. That ability lets Terran players reposition a base, avoid threats, or establish an expansion in a new location. The lifted structure cannot operate normally until it lands again.
