O Battery (The Rocket Troop) Royal Horse Artillery

O Battery (The Rocket Troop) Royal Horse Artillery is a field artillery battery within the Royal Horse Artillery (RHA) of the British Army. Its lineage traces back to the early development of rocket artillery within the British military during the Napoleonic Wars.

Originally raised as a separate unit dedicated to rocket deployment, O Battery's history is intertwined with the experimental and operational use of Congreve rockets. These rockets, developed by Sir William Congreve, were employed in various campaigns during the early 19th century.

Over time, as artillery technology evolved, O Battery transitioned from being solely a rocket-firing unit to a more conventional field artillery battery, while retaining its historical association with rocket artillery in its name and traditions. Its role expanded to encompass the use of conventional artillery pieces alongside specialized rocket systems as technology advanced.

Currently, O Battery (The Rocket Troop) forms an integral part of the Royal Horse Artillery, contributing to its operational readiness and participating in both ceremonial duties and deployments. The battery maintains a strong esprit de corps and a dedication to upholding the traditions of the RHA. While its direct use of rockets may vary depending on contemporary military requirements, its historical identity as "The Rocket Troop" serves as a reminder of the pioneering role it played in the development of British artillery. It actively participates in parades and historical reenactments to keep its historical heritage alive.
