Allied Rapid Reaction Corps

The Allied Rapid Reaction Corps, is a North Atlantic Treaty Organisation High Readiness Force Headquarters ready for deployment worldwide within five to thirty days.HistoryThe ARRC was created on 2 October 1992 in Bielefeld based on the former British I Corps (or I (BR) Corps). It was originally created as the rapid reaction corps sized land force of the Reaction Forces Concept that emerged after the end of the Cold War, with a mission to redeploy and reinforce within Allied Command Europe (ACE) and to conduct Petersberg missions out of NATO territory. The first commander, appointed in 1992 was General Sir Jeremy Mackenzie.From 1994 the ARRC was based in the Rheindahlen Military Complex, Germany. It commanded the Land Forces of NATO's first ever deployment as part of the IFOR operation in Bosnia in 1995/6 and was again deployed as the headquarters commanding Land Forces during the Kosovo War in 1999.Since 2002 however the HQ has been re-roled (with five other corps HQs of other NATO nations) as a High Readiness Force (Land) HQ (HRF(L)) with a broader mission. The formation HQ is under Operational Command of Supreme Allied Commander, Europe (SACEUR). The ARRC has a national Force Pool of Combat, Combat Support and Combat Service Support units with which to train and execute its mission. However, in reality COMARRC commands no forces until he receives an Activation Order from SACEUR. On receipt of ACTORD, forces from troop contributing nations, generated through the NATO Force Generation process are passed into his Operational Command for the duration of the operational deployment.
