This is the senior regiment of line cavalry in the army. It was raised in 1685 as the 2nd Queen’s Regiment of Horse, becoming the King’s Regiment of Horse in 1714 and the 1st King’s Dragoon Guards in 1746. Mechanised with light tanks in 1937 it became part of the Royal Armoured Corps in 1939. It amalgamated with the 2nd Dragoon Guards (Queen’s Bays) in 1959 to form the 1st The Queen’s Dragoon Guards. They fought under Marlborough and Wellington, in the Crimea, China, and South Africa, and the last two World Wars and later in Aden, Iraq, Bosnia and Afghanistan. This Officer is dressed for parade in peace time. Based on civilian fashions of the time, there is no evidence such a coat was officially sanctioned. Officers tended to ignore dress regulations and wore what they liked.
