Alright then, if you want to fight for the people of Crayter and the continued freedom of the Taus and Sirius, pick up your uniform from the Republic's Military Offices on Pecos. There's also some trading available, and of course you can roleplay as much as the other players you meet are willing.
Alternatively, send your CV to the Independent Miners Guild recruitment officer and he'll be able to get you, and anyone else you may know with an interest, in a transport/mining/paramilitary ship.
Also, glad you've had some good interaction Manticore.
Jack is also one to know how it is in the IMG and CR
