1 Regiment Royal Horse Artillery (1 RHA) is a premier Close Support Artillery regiment within the British Army, primarily tasked with providing offensive fire support to armoured and mechanized brigades. Based at Larkhill Garrison on the edge of Salisbury Plain, they are currently transitioning from the tracked AS90 to the Archer 155mm wheeled self-propelled gun, a modern system capable of rapid deployment and high-precision strikes. As a Royal Horse Artillery unit, they maintain a distinct identity and traditions separate from the wider Royal Artillery, prioritizing speed and mobility to keep pace with frontline combat vehicles. 1 RHA is heavily committed to operations and readiness, frequently deploying on major exercises and serving as a key component of the Army’s warfighting division, offering critical "deep fire" capabilities to suppress enemy targets before ground troops engage.
