One Riot, One Ranger: Played straight, inasmuch as there are people around in various agencies (the Constabulary’s “Specials”, ExSec, the Shadow Fleet, the Imperial Hands, the Operatives of the Presidium) with that sort of omnicompetence and air of authority. Very useful instrumentalities to have in various special circumstances.
Mildly subverted when some of them come with their own entourage.
Grossly subverted with horrible cheating when they know the rioters aren’t going to be impressed by a chat – so they send in one legionary in his combat exoskeleton… and a lot more combat drones slaved to its tactical processors. An Army Of One, indeed.
