The SAS took part in the 2003 invasion of Iraq under the codename: Operation Row, which was part of CJSOTF-West (Combined Joint Special Operations Task Force – West) B and D Squadrons carried out operations in Western Iraq and Southern Iraq; towards the end of the invasion, they escorted MI6 officers into Baghdad from Baghdad International Airport so they could carry out their missions, both Squadrons were replaced by G Squadron in early May. The US military designated the SAS element in Iraq during the invasion as Task Force 14; in the months following the invasion, the SAS moved from Baghdad International Airport to MSS Fernandez in Baghdad, setting up and linking its "property" next to Delta Force, in summer 2003, following a request for a new mission, the SAS began Operation Paradoxical: The broadly drawn operation was for the SAS to hunt down threats to the coalition, SAS were 'joined at the hip' with Delta Force and JSOC, it also gave them greater latitude to work with US "classified" forces – prosecuting the best available intelligence. However, in winter 2003, they were placed under the command of the Chief of Joint Operations in Northwood, due to scepticism of Whitehall members about the UK mission in Iraq – making it more difficult for the SAS to work with JSOC.
