The Joint Rapid Reaction Force (JRRF) is a formation of the British Armed Forces; it consists of a pool of specialised units from all three armed services tasked with rapid deployment worldwide at short notice. The force is intended to be capable of mounting operations up to medium scale warfighting. It can be employed nationally, or multinationally under the auspices of NATO, the European Union, the United Nations or any other coalition.


The JRRF was an initiative in the 1998 Strategic Defence Review. An initial rapid reaction capability was declared in April 1999 and was fully operational in 2001.[1] It was originally intended that JRRF would be able to mount up to two simultaneous operations of up to 15,000 personnel each.[2] A major military exercise called Saif Sareea II was held in Oman in September 2001 to test the deployment of the JRRF.[3]


In the event of the JRRF being activated, the force commander is the Chief of the Joint Rapid Reaction Force (CJRRFO) who is responsible to the Chief of Joint Operations (CJO) at the Permanent Joint Headquarters at Northwood. A Joint Task Force HQ (JTFHQ) would accompany the force to provide local command, which is maintained at 48 hours notice to move. Until deployed, operational control of the various units is the responsibility of the single-service Commanders-in-Chief.[4]
