**HQ CONAC ARRC (IRS)** refers to the Headquarters, Corps of the Allied Rapid Reaction Corps (Interim Rear Support). The Allied Rapid Reaction Corps (ARRC) was established in 1992 as a high-readiness multinational headquarters under NATO, initially based in Germany and later relocated to the United Kingdom. The HQ CONAC ARRC (IRS) provided crucial logistical and rear-area support to ensure the ARRC's operational effectiveness during deployments, particularly in the Balkans and Afghanistan. This unit played a vital role in coordinating supply, transportation, and support services, underpinning NATO's rapid response capabilities in various peacekeeping and combat operations since the early 1990s.
