Interesting thought. Clan Hamato in IDW is basically just a shinobi family. A paramilitary group usually has some kind of charter or manifesto, even if it's a "for sale" sign with enough military discipline and heavy arsenal to take over a town. So I'd probably list (and tell me if you disagree): I probably wouldn't include most street gangs or organized crime groups. I'm not sure whether I'd classify well-armed militant hive minds, like Ferd's group or the Kraang (2012 TV series). They're disciplined, but that discipline actually comes from a central authority psychically controlling them rather than forming an organized command structure of independent minds.

 * Street gangs usually lack military discipline, whether as a warring gang or as a benign neighborhood watch. So maybe not the Purple Dragons or Madhattan Maulitia.
 * Organized crime generally has structure and weapons, but reflexively avoids making too much of a mess in public that would give the authorities enough hard evidence and probable cause to gut their organization. Where they do operate more publicly, it's usually in a social environment that directly enables it;  for example, the Sicilian Mafia is called Cosa Nostra ("Our Thing") for a reason, and the code of silence (omertà) that allows them to operate so efficiently is actually a traditional value practiced by the local communities their rank and file come from, making their group more like a social institution than a mere gang.
