The Great War
The 6th (Inniskilling) Dragoons was a Cavalry Regiment that would have had an MG Section as part of its Regimental Headquarters. These weapons would have been brigaded when the Machine Gun Corps was formed in 1915. The guns, and crews, would have been formed into a Machine Gun Squadron.
In 1922, the 6th Dragoons were amalgamated with the 5th Dragoon Guards to form the 5/6th Dragoons.
