On 16 January 2013 HQ ARRC formally took over the role of the NATO Response Force (NRF) during a ceremony at Imjin Barracks when the ARRC commander, Lieutenant General Sir James Bucknall, accepted responsibility from the commander of NATO Rapid Deployable Corps-Greece, Lieutenant General Georgios Basiakoulis. The ARRC remained on NRF status for the whole of 2014, relinquishing responsibility in January 2014.

In July 2015 HQ ARRC was placed on standby as a certified Joint Task Force (JTF) headquarters in order to oversee small, joint land operations should the need arise. HQ ARRC had certified for such a role the preceding May at Joint Warfare Centre in Norway during Exercise TRIDENT JAGUAR 2015. The ARRC remained on such status for approximately a year.

In January 2017 HQ ARRC assumed responsibility as the Land Component Command (LCC) element of the NATO Response Force (NRF) during a ceremony at Imjin Barracks whereby the ARRC commander, Lieutenant General Tim Radford, assumed responsibility from the commander of NATO Rapid Deployable Corps-Spain. Over the course of 2017 HQ ARRC acted in its capacity as the LCC during one of NATO's capstone exercises - Exercise NOBLE JUMP 2017 - and supervised the movement of approximately 5,000 NATO troops from across Europe to NATO's periphery in Romania, the first time in NATO history such a movement had been conducted. In November 2017 HQ ARRC executed its own capstone exercise, Exercise ARRCADE FUSION 2017, which saw the command and control of five separate divisions in a notional setting whilst simultaneously and successfully testing the ARRC's 'Survive to Command' concept.

 

HQ ARRC relinquished NRF responsibility to NATO Rapid Deployable Corps-Italy on 10 January 2018.
