Band of Five IMO offers a lot more for Bannson than just a combined arms regiment . . . you are talking about being able to find some special, if nasty, skill sets in the unit to push Bannson's position.
You probably should have someone who can arrange a 'innocent' hit and run vehicular accident.
Definitely arrange a honeypot blackmail plot
Criminal types . . .
Smugglers
Arson for hire
armed bank robbery
hitmen/assassination
bounty hunters? skip tracers?
organized crime strongmen- Capellan Triads, FedSuns mafia
then you just get to scum- murders, rapists, kidnappers, sadists, and tax lawyers
If you really go in depth though, the unit would not be very PG when you start including the worst types.
