[member="Matier"] In the rules you quoted, it clearly indicates large fleets and armies.
So a Minor Faction, and indeed anyone, can have fleets and armies. They just can't be subjectively large in comparison to a Major Faction, who will always have a bigger fleet/army.
I was mentioned, so I joined to read my tags, and I saw something I could clarify.
Also a suggestion, since I saw mention that literal mergers between factions were impossible, if by some miracle the Republic and this minor faction hoping to become Major, wanted to merge with the Republic. They could begin the slow process of diplomatic "Invasions" which slowly re-incorporate old worlds into the Republic. So essentially, Dominions, except they are protected in a "queue" by an allied faction. If that makes sense.
Food for thought!
*fatty, out!*
