Sounds like your group could be perfect for the Native guerrilla factions. That is unless you want to be from Anuira.

Descended from the natives of Anuira, I am thinking. Then they landed somewhere else, settled down, where pretty cut off from the rest of the universe, and so only got news of the planets fate recently, which would explain why they haven't been a constant presence for the whole of the war. (Because, if you keep losing a bunch of men without any reason, explanation or bodies of the other guys, then someone would start looking into it eventually)
