USI's Ranking Structure. This does not apply to other Factions or Organizations. It is important to note that USI doesn't use the concept of ranks being "Enlisted", just "Officer" ranks. This is because USI is not tied to any government as a form of Military, they are their own individual Military Faction. Many other factions and government view USI as a Rogue or Mercenary group, however they are recognized as being a universe power.
