1) I would add something about the goals of the movement itself. How they actully see the future of Bretonia after Gallic victory and parade in New London.
2) The relationship with GRN shall not be so cordial. Hwo betrayed onece could betray twice. In this case in the lore would be right to define them as the police forces under Ryal Navy command. The main task of them is the rear guard including the supply lines. They could be relocate to the frontline only in emergency situations. In the game they could act according to the GRN ID.
Agreed with the Sturmwind about the names and ability to parallels with real collabortianists.
