Medical Terminal - big NO NO.
I thought about being a Vault City Citizen as requirement to buy this base. However medical terminal isn't necessary, I think it could encourage people.
Ranks! Faction ranks! Obtainable by quests! Citizen -> militiant -> ensign -> soldier -> outpost commander!
It looks good.But it doesn't make sense. Vault city itself is , well, a city, a big community, a fortress.It's one big city, they don't have outposts like that.
If you want to make enemies, try to change something.
