Also I wanted to share my characters backstory so that you can get an idea on why he would decide to create this group.
Before joining the Army my character used to be a professional body builder who one day got the opportunity to audition for a new upcoming TV series of Grognak the Barbarian. He won the role of Grognak even though he had no real talent. The producers didn't mind because all he needed to have was the look to play a muscular barbarian.
After 3 years of playing the iconic character he decided to join the arm forces after hearing that the commies were invading Alaska.
Post Great War and after what happened to his wife and child he took on the persona of Grognak to be able to cope with the tragedies that have befallen him. So basically he has been going around ripping apart any one that would bring tragedy to any inoccent person in the commonwealth, but Grognak can't bring order to the wastelands on his own. After barely escaping death on several occasions he now realises that he's going to need the support of his friends to be bring justice to the wasteland.
So please post your ideas and please refrain from leaving any main story spoilers. Thank you..
