The "United Nations" was one of the many political entities founded after the fall of the Combine. Founded by former American Congressman and City Administrator Alexander Urban. It is widely resented by some, due to the fact that it is seen to the spiritual successor to the Universal Union due to the fact that it was created by a former City Administrator and it's armed forces are majority made up of formerly Metropolice Force and Conscript units - the Conscript uniform coming in as the standardized one for the armed forces and police.

Due to it's authoritarian policies, the state had a massive migration crisis in the early stages of post-Combine rule, with many of it's "citizens" fleeing across the wastelands of Southern Europe or East into Lambda territories.

Due to this, the nation has a manpower problem when it comes to it's military. But what it lacks in numbers, it makes up for in tactical prowess and technological strength.
