106 (Yeomanry) Regiment Royal Artillery is the British Army’s dedicated Reserve Air Defence unit, headquartered in Grove Park, London, with sub-units positioned across the South East in Portsmouth, Southampton, and Milton Keynes. It holds the vital role of providing Close Support Air Defence to maneuver forces, operating the Starstreak High Velocity Missile (HVM) system via both the armoured Stormer vehicle and the portable Lightweight Multiple Launcher (LML). Under the Army's "Future Soldier" structure, the regiment is a key component of the 7th Air Defence Group, where it works in tandem with the Regular soldiers of 12 Regiment Royal Artillery to shield ground troops from enemy helicopters and low-flying aircraft. Despite its high-tech role, the regiment preserves a deep historical lineage, carrying the "Yeomanry" title that connects it to the volunteer cavalry traditions of the past.
