The Rangers have nothing against marauders - on the contrary. They work together to fight kitins, especially in the ATs. Don't confuse the ideology of Akilia and her clan (destroying nations) with that of most marauding clans, which only want to break away from nations, not necessarily destroy them. When you say "enemy of all homin societies", the Maraud clans form societies. Putting Maraud missions in the Ranger camp could be just the opportunity to shatter certain myths that Marauds are just ugly, ugly people who only want to see the world burn. Not a bad idea.
but I can't see chiang (rangers) getting involved with the marauders (enemies of all homin societies).
Likewise, the marauder camp should not be in the ranger camp.
it's a bit like IRL governments accepting ambassadors representing all the world's terrorist organizations...
after the creation of new missions must represent a huge amount of work...
