The regiment took part in the Iraq War, notably carrying out operations in Iraq before the 2003 invasion. Following the invasion, it formed part of Task Force Black/Knight to combat the postinvasion insurgency; in late 2005/early 2006, the SAS were integrated into JSOC and focused its counterinsurgency efforts on combating al-Qaeda in Iraq and the Sunni insurgency alongside Delta Force. The counter-insurgency was successful, and the UKSF mission in Iraq ended in May 2009. Overall, more than 3,500 terrorists were "taken off the streets" of Baghdad by 22 SAS.
