Global Defense Initiative
The United Nations' military arm, and the world's shield against Nod and Tiberium. GDI fights with heavy armor, strong air power and orbital weapons: slow to start, very hard to stop.
Through the games
- Tiberian Dawn: the Mammoth Tank, Orca aircraft and the Ion Cannon from orbit.
- Tiberian Sun: walking Titans and Wolverines, hover units, the Mammoth Mk. II and the Firestorm defense wall.
- C&C3: Predator and Mammoth tanks, Juggernaut artillery, Orcas and Firehawks, and the Ion Cannon again.
How to play them
GDI wins head-on fights. Protect your harvesters, build up a strong tank force, and push with support from the air. In C&C3, Kane's Wrath adds two sub-factions, the Steel Talons and ZOCOM.
