British Army Lieutenant General Sir Edward Smyth-Osbourne, commander, Allied Rapid Reaction Corps, addresses NATO troops at the Royal Air Force station in St Mawgan, United Kingdom, Nov. 25, 2019, during Exercise ARRCADE FUSION 19. Smyth-Osbourne said, "We are required to be at readiness on 1st January as the ‘warfighting corps’ headquarters, at 20 days’ notice to move for operations in the European theatre, both to deter our adversaries and to defend our allies.” The training was supported by experts from across NATO, with specialists flying in from all corners of the Alliance including the US Army’s 1st Cavalry Division from Fort Hood, Texas, the 1st Canadian Division from Kingston, Ontario, the Portuguese ‘Brigada de Reacção Rápida’ (Rapid Reaction Brigade), as well as the British Army’s 3rd (UK) Division from Salisbury Plain. Supporting staff also travelled from the ARRC’s sister corps headquarters, including the NATO Rapid Deployable Corps Italy (NRDC-ITA) based in Milan, and the Multinational Corps Northeast from Szczecin, Poland.
