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.[3]
