The United Nations Forces is the unified army composed combined military forces of Union, AEU, and HRL to eradicate Celestial Being.
Operation Fallen Angels
After given 30 GN T Drives in A.D. 2308, the three world powers united all their military resources to destroy Celestial Being. In a public display of united commitment, all three leaders publicly announced their new coalition on the news and called their anti-Gundam campaign Operation: Fallen Angels. After chasing off Team Trinity, they hunted down the rest of Celestial Being in space and successfully defeated them.
After successfully fending off Celestial Being, unity between all nations continued and a new level of prosperity reigned. Eventually in A.D. 2311, the United Nations was reformed into the Earth Sphere Federation and one year later, in A.D. 2312, the various nations of the Earth Sphere Federation disbanded their army to form the singular Earth protection force, the Earth Sphere Federation Army. A new elite force, the A-Laws, was also created under direct orders of the Federation.
