But, what should we infer by this? Rogue One suggests they are ISB or special project troops. We don't see them with Vader, but we see them with a Grand Admiral. I can't make sense (for game purposes) of their official Imperial use or branch.
According to the Databank , they're bodyguards and enforcers. They must be set aside for the upper echelon of the Empire/Imperial Military (especially very active, mobile members like Krennic and Thrawn). Vader doesn't use them, because why would he? He doesn't need bodyguards, and he does his own enforcement work.
