United Forces of Earth

While I assume this is a military alliance, the series doesn’t make it entirely clear^A). It’s possible that the UFE are a federation or even a centralized state.
As the name suggests, they are based on the planet Earth, and their number one goal is to defend it from a second Martian invasion.
This…unclear organization was founded after the first Martian invasion. For whatever reason, they’re also involved in a lot of censorship, some coming off as needless.
Among the examples of their tampering:

We don’t know almost anything concrete about the founding of the Empire of Vers. This includes not knowing the exact chronology, alongside not knowing the dates^B), or even what events led to their independence.
The UFE hid the truth surrounding the Martian invasion - specifically the fact that Martians had landed on Earth. They’re also possibly hiding the technological disparity.

^A) To be fair, we barely see anything outside of the military - as most of the characters are soldiers during a war.

^B) I realized this is written kind-of strangely, so I’ll elaborate here, before I decide to fix it. By chronology, I mean that it isn’t clear in what order events occurred, while dates means we don’t know specifically when those events happen. Not exactly the same thing, although very similar.
