The 5th Royal Inniskilling Dragoon Guards was a cavalry regiment of the British Army in existence from 1922 to 1992, when it was amalgamated into the Royal Dragoon Guards.
The regiment was formed in 1922, as the 5th/6th Dragoons, at Cairo, Egypt by the amalgamation of the 5th Dragoon Guards (Princess Charlotte of Wales’s) and The Inniskillings (6th Dragoons).
In 1923, the regiment was deployed to Risalpur, India. In 1927, the regiment discarded the “6th” and inserted Inniskilling into its title, thereby becoming the 5th Inniskilling Dragoon Guards. In the following year, the regiment returned to the UK for the first time, as the 5th Dragoon Guards. In 1935, it gained the Royal accolade to become the 5th Royal Inniskilling Dragoon Guards.
