"The 4th/7th Royal Dragoon Guards was a cavalry regiment of the British Army formed in 1922. It served in the Second World War. However following the reduction of forces at the end of the Cold War and proposals contained in the Options for Change paper, the regiment was amalgamated with the 5th Royal Inniskilling Dragoon Guards, to form the new Royal Dragoon Guards in 1992." - (en.wikipedia.org 11.08.2021)
