On November 23 , 2005 , Brown , together with U.S. Secretary of Defense Donald Rumsfeld , and Marine Corps Commandant General Michael Hagee announced the creation of the Marine Corps Forces Special Operations Command ( MARSOC ) . Prior to the creation of MARSOC , the Marine Corps had not been involved in special operations , which were conducted by Army , Navy and Air Force units assigned to U.S. Special Operations Command . After the September 11 attacks , the Secretary of Defense had directed the Marine Corps and Brown 's predecessor to work closer together in the Global War on Terror . This culminated in the creation of MCSOCOM Detachment One on June 19 , 2003 , shortly before Brown took command of USSOCOM . It was nearly three years later on February 24 , 2006 , when MARSOC was activated at Camp Lejeune , North Carolina
