The Global Defense Initiative, or GDI for short, operates a well-organised military around the globe. Infantry and ground armor make up its main fighting force under your command, supported by the iconic Orca helicopter and the multi-role Firehawk aircraft. In addition, GDI's commanders can call on tactical airlifts, reinforcements (even from space!) and the awesome power of the orbital Ion Cannons.
For a full list of support powers and unit upgrades, please refer to the
tech tree.
All structures are built at the
Construction Yard. Additionally, structures can be built in a simultaneous build queue at every
Crane, but Cranes cannot build defensive structures (Watchtower, Guardian Cannon, AA Battery, Sonic Emitter), super weapons (the Ion Cannon Control Center), other Cranes, or Surveyors. Structures are produced into two separate, independent build queues, one for main structures (Crane, Power Plant, Refinery, Barracks, Armory, War Factory, Command Post, Airfield, Tech Center, Space Command Uplink) and one for support structures (Tiberium Silo, Watchtower, Guardian Cannon, AA Battery, Sonic Emitter, Ion Cannon Control Center).
