Grand Army of Justice

The Grand Army of Justice was a vigilante group based on Coruscant, consisting of regular humans which used clone armour and weapons, inspired by both the Grand Army of the Republic and The White Ghost. One of it's leaders used the clone-esque nickname of Viper.

Emerging in 14 BBY, the vigilantes were much more violent than their idol, having no qualms about using violence bordering on terrorism to track down criminals.
