Depends on weather the Realm Officers want to include your unit into the Royal Army or as a Mercenary unit supporting the Army.
Mine is the War Wolves. The full title I've given to the unit is the War Wolves of Barad'Dun, however, we are a Norse Brotherhood, thus a unit of independant Mercenary types. We do have a Brother now in Tennessee. K'urn, a good friend of your Brother's. Since he talked about possibly forming War Wolves out there, He is his own ship master (War Wolves belong to a ship. I am shipmaster here in Barad'Dun of the ship 'Raven's Wind' and everyone who joins is a crewman on said ship) He will form his own ship and crew. They will not neccessarily be apart of Barad'Dun, but through ties with us, they are a part nontheless.
My unit has its own banner, but here and there I incorporate symbols of Barad'dun. Symbols such as the colors, Red, Khaki, black, gold. The Golden Tower, and the Red 8 pointed star. We are a separate unit, but through a contract signed by your brother, we are mercenaries both of the Royal army and Royal Navy. Look under the topic "Our Chapter", and then read everything under the topic "About Barad'Dun". and then let your imagination flow. Your unit could be similar. to mine. They could be "the Northern Guard" mercenaries of Barad'Dun or "The Northern Guard of Barad'Dun."
Your enthusiasm and excuberance are heart warming. I'm sure the Officers will help you as soon as they can.
Huzzah to the Barad'Dun Brotherhood.
