It's been a concept since 1895. It's not like Halo popularized that.

The UNSA... Yeah it's similar but that's also because both are part of the United Nations. There isn't much else they could have done more so since they don't want to remove all connection to the past. (I.E. UN is a concept right now, therefore it would still exist 110 years from now.)
Also to be fair, Halo itself isn't in the naming. UNSC is a real thing. United Nations Security Council.
In fact...
Guess what game series is this from?
Halo UNSC is United Nations Space Command. The ring was definitively popularized by Halo.
The Jorge ripoff is blatant.
