This is what I would imagine the VEGA Outer Mining ranking structure would be. If you guys like it, i'll add more then just the officer positions in VEGAs thought of military. There are a lot of N/As in this. That's because we don't know of anyone else in VEGA other then Rumbelow and Vorzer.
President of VEGA Outer Mining- N/A
Vice President of VEGA Outer Mining- Rumbelow
Rank: Field Commander
Description: Commander of VEGA Outer Mining Operation's armed forces. As of this time, there is only one that we know of, and probably only one in total.
Rank: Cluster Admirals- N/A
Description: Since there are multiple clusters, there may be multiple Commanders involved in running them
Rank: Sector Admirals
Description: Due to the amount of VEGA activity and organization in each sector, there may be multiple men responsible for managing and meeting quotas.
Rank: System Admirals
Description: To break it down further, there may be multiple System Commanders over each cluster of 5 planets. This creates further organization for VEGA Outer Mining
Rank: Planet Admirals
Description: The first administrative officer rank. These individuals are tasked with knowing everything the planet they oversee, and are the ones responsible for the leaderboards that we see. They keep a list of the individuals who attack the most and do the best based off a "Medal" system. The list is then turned into a public leaderboard for the sector so that the rebels can destroy each other to gain notoriety from VEGA, and one day potentially get rewards for it. Who knows?
