History
The unit's creation stems from the need to provide infantry support to the special forces. Previously, this was done on an ad hoc basis as conventional units of the Royal Marines and the British Army assisted special forces teams when needed. Units like the Parachute Regiment were sometimes deployed in such a manner, such as for Operation Barras in Sierra Leone.
In December 2004, it was announced that a unit would be formalized for this role as part of the wider restructuring. It was initially coined as a battalion of Rangers in reference to the US Army 75th Ranger Regiment (although not similar).
Its creation was announced officially by the then Secretary of State for Defence John Reid in Parliament on 20 April 2006. Following the announcement, it was reported that a company of SFSG soldiers was operating in Iraq as part of the US-led Task Force 145.
