21st Lancers

The 21st Lancers 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 Machine Gun Corps was disbanded and the 21st Lancers was merged with the 17th Lancers to form the 17th/21st Lancers.
