SEAL Team 6, founded by Richard Marcinko in 1980, is responsible for U.S. counterterrorist operations in the maritime environment. They were made famous by their founder, who chronicled their beginnings in his autobiography "Rogue Warrior". Nowadays the correct name for this elite force is DEVGRU or the Naval Special Warfare Development Group. The reason for the disbandment and recreation of the team seems to be the fact that the Navy though Marcinko gave out a little too much info in his books. DEVGRU is currently based at Dam Neck, Virginia.
