As a High Readiness (Land) Force, HQ ARRC is ready to deploy under NATO, EU, coalition or a national force to undertake Combined and Joint operations across the operational spectrum.


Under its leading NATO role within UK Defence, ARRC operates as a 3-Star headquarters, in Gloucestershire, with more than 400 permanent staff from more than 20 nations contributing to NATO activity every day.

Its unique structure allows the ARRC to operate as a Corps Headquarters, a Land Force Component Command, a Joint Task Force Headquarters, or to augment ongoing operations with select staff capabilities. It also assumes the role of the NATO Response Force (NRF) Land Component Command on a rotational basis, which demands personnel of high levels of fitness, training, education and readiness to deploy.

In April 2015, a UK Defence restructuring aligned the ARRC under the British Army to improve direct support to the HQ. Direct support, like that currently provided by 1(UK) Signals Brigade, enables the ARRC HQ to test command configurations, experiment with response time planning and deploy.

Working at the ARRC affords aspiring personnel the opportunity to plan, train, and deploy on missions and exercises of the highest strategic importance under the command of a British Army Lieutenant General, and the leadership of several other senior officers from different nations. The fast-paced and innovative working routine is geared towards global uncertainty and applies professional education to solving the complex problems facing the UK and the NATO alliance today. The ARRC also offers part-time training opportunities for British Reservists and full-time jobs for uniformed personnel and civilians from across UK Defence.


Formed in 1992, based on the British 1 Corps model, the Allied Rapid Reaction Corps was built to conduct specific NATO missions in Europe under the NATO Allied Command Europe defense structure at the end of the Cold War.

A mission expansion in 2002 made the ARRC the High Readiness Force (Land) Headquarters it is today, able to command as many as 60,000 ground troops on operations. The ARRC remains prepared to deploy under NATO, EU, Coalition or National forces in support of a wide range of Multinational and Joint operations.

The ARRC has performed its mission for nearly two decades in Germany, deploying on operations to:

  • Bosnia Herzegovina 1995 to early 1996: NATO led Peace Implementation Force based in Sarajevo.
  • Kosovo 1998 – 1999: based in Macedonia after signing of the Military Technical Agreement.
  • Afghanistan May 2006: 9 month tour assuming command of HQ ISAF.
  • Iraq May 2008: HQ ARRC provided two teams to mentor Iraqi HQ in Basra.
  • Kabul November 2009: HQ ARRC provided a short notice team to set up and run the Force Integration Cell.

HQ ARRC relocated from Germany to Imjin Barracks, in Gloucestershire, in 2010.
