The United Nations Global Defense Initiative (UNGDI), or Global Defense Initiative (GDI), is the premier polity of Earth. It was founded as a formalized military branch of the United Nations at the end of the 20th century and evolved into a supra-national state in its own right. GDI's initial goal was to preserve world order by combating global terrorism, epitomized by its nemesis, the Brotherhood of Nod. Its mandate expanded to global environmental protection with the spread of Tiberium.

During the First Tiberium War, GDI fought Nod forces on a multitude of fronts. Eventually, Nod propaganda efforts painted GDI as being responsible for atrocities such as the slaughter of the entire population of Bialystok, through a series of false news broadcasts recorded by Greg Burdette. This forced GDI to pull back from many territories, which were then quickly taken over by Nod supporters. Ultimately, the UN was forced to discontinue its public funding of GDI due to the fear of public backlash. Nod began assaulting GDI strongholds everywhere, believing that the organization had been severely weakened by these manipulative efforts.

With the destruction of the Brotherhood's Sarajevo Temple, a period of peace dawned, allowing time for GDI to renew its efforts into researching Tiberium and to study the Brotherhood of Nod's enigmatic and radically advanced Tiberium-based technology. However, GDI forces never recovered Kane's body which was considered by many to be the biggest oversight of the entire war. During these years tabloid headlines and rumors of the continued underground existence of the Brotherhood were commonplace, prompting GDI to conduct investigations into these sightings before eventually sealing each case with few questions answered. The world remained largely at peace until September 2, 2030, when GDI bases around the world found themselves under heavy fire from Nod units. Aboard the "Philadelphia", GDI's top brass could make little sense of it; the Brotherhood as an organized and globalized militant force was supposed to have been almost eliminated and left divided into small and harmless splinter groups after Kane's death. And then the unthinkable happened.

Tiberium EssenceEdit

Tiberium Wars GDI Flag

In Tiberium Essence's storyline, Instead of moving on from the Second Tiberium War and develop new technologies, GDI re-deploys their iconic units from the Second Tiberium War, ranging from Disk Throwers to the legendary Mammoth MK II walker. It also retained some of the new units introduced in Tiberium Wars, such as the Mammoth 27.

GDI's core tactics remain mostly the same. Slowly advancing, but with heavy firepower.
