On June 19, 2003, Marine Corps Special Operations Command Detachment One, also known as “Det One”, was created as a pilot program to assess the value of Marine special operations forces permanently detached to the United States Special Operations Command. It was commanded by Col. Robert J. Coates, former Commanding Officer of 1st Force Reconnaissance Company and it was headquartered at Camp Del Mar Boat Basin. Det One was disbanded in 2006 and succeeded by the permanent United States Marine Corps Forces Special Operations Command (MARSOC).
