While I will do a truly alien species at some point, I decided on that a good counterpoint to the SpecOps teams of the Hell Divers would be a futuristic cartel-type insurgents/pirates. Here is the first look at the Rim Defectionists. Operating on the fringe of known space these groups contain mostly humans but are also a home for the more unsavory alien fugitives... Heavily armed and armored (even if it is stolen, or last gen tech) they have been the bane of many trade ships and minor colonies.
