NATO drills a high‑tempo, 2030 defence snapshot: a disused London Tube platform doubles as ARRC HQ for a multinational wargame. ARRC is NATO’s high-readiness land force HQ.
NATO’s ARRC-led exercise, Arcade Strike, has been staged in a secret London bunker and in Estonia to rehearse a Baltic defence if Russia invades. The drill uses drones, AI and electronic warfare to identify and strike targets, testing how alliance forces could coordinate up to 100,000 troops.
