Deputy Commissioner Magnus Page here, I was the officer aboard the Schiehallion who took that batch of Corsair prisoners from you in Omega-3. I've had this forwarded to me by the Armed Forces, as it is the BPA who deal with this sort of licensing.
The Military Materials Licence is what you are looking for, and transport pilots may register themselves in this channel.
As I said to you in space though, if you are still carrying Rheinland Military Papers you will not be able to enter Bretonian space under our Espionage laws, at least without explicit permission from our Admiralty. If you are looking for another type of transport there should be no problem, but this channel would be useful for yourself.
"Thank you Deputy Commissioner Magnus Page" Rerouting.....
To the high command of the Bretonian Armed Forces
The RMT-Odenwald is looking for permission to enter the Bretonia Worlds to transport Military Grade Supplies to the Bretonia Colonies in effort against the war with Gallia. I require your Explicit Permission to transport military supplies to your Home Colonies. I will be using a Behemeth with Rheinland Military papers, and apply for a Military Materials Licence if approved here. As a Military Supply ship appon acceptances. The RMT-Odenwald will adhere to any fourth rules that you lay down from daily inspection to scans to selling Cargo at a location which needs it more then other.
First of all, please allow me to apologise on behalf of our Kingdom and its Armed Forces for the delay in answering you.
The Admiralty has decided not to allow your transport to trade openly within Bretonia. As I understand has happened in the past, you may hand over prisoners to the Bretonia Police Authority's Commerce Control Division in the Omega systems. For other cargo, either hand it over to another transport captain (for example Bowex) or hire a registered Rheinland vessel to do the same.
You will still be subject to Espionage laws if you pass Freeport 1.
