So if I understand right you are going to police the boarders right? And not get involved in military conflicts? If this is so than wouldn't it sound better to say that your were a Boarder Patrol Agency? How about naming it Bretonia Boarder Patrol?
To me it makes more sense, to do that. And also what if Liberty and Bretonia developed hostilities they would take entering boarder systems as acts of aggression by 'military forces', with it being an anti-pirate thing boarder patrol seems to make more sense, especially since you will not necessarily be the police force for all Bretonia.
