Operation Herrick is the codename under which all British operations in the War in Afghanistan were conducted from 2002 to the end of combat operations in 2014. It consisted of the British contribution to the NATO-led International Security Assistance Force (ISAF), and support to the American-led Operation Enduring Freedom (OEF). Since 2003, Operation Herrick has increased in size and breadth to match ISAF's growing geographical intervention in Afghanistan. The UK ceased all combat operations in Afghanistan and withdrew the last of its combat troops on the 27 October 2014.
