Either way, any mopup against the Black Lance forces is going to be tough. The Black Lance are Special Forces operatives, genetically enhanced soldiers who specialize in guerilla warfare. The Black Lance was from a renegade portion of Confed Special Ops, and they don't fight by the book. Look at their "unconventional" weapons, fighters, and capships, and you can see their means of fighting is unorthodox. They think out of the box.
Of course, there were some guys who weren't extreme as their peers, as they grumbled about the Telamon Operation and you see Chris Roberts in a Black Lance uniform saying "and I couldn't go on!" in the ending of WC4. I can really see them trying to come back into Confed and try to set right what they've done wrong. But the more extreme will most likely not go down without a fight.
Afterall, how hard can a fight be, when the objective is to hunt down a group specifically trained to dissapear when expected and attack when not?
Very . . .
