(I put a spoiler warning on this, just in case some players would rather find the subfactions on their own.)

I think this would be a good place to direct subfaction questions. (Legostarwarseu, please delete if not allowed)

But can The Empire of the Hand build special subfaction units/heroes? I noticed their unit and hero rosters in the Rouge Squadron GC are a bit small and they only have 4 heroes (not including the Thrawn Clone)
