The Blues and Royals are the only regiment in the British Army to allow troopers and non-commissioned officers, when not wearing headdress, to salute an officer. The custom was started after the Battle of Warburg in 1760 by the Marquess of Granby, who commanded both the Royal Horse Guards and the Royal Dragoons. These were separate units at the time. During the battle, the Marquess had driven French forces from the field, losing both his hat and wig during the charge. When reporting to his commander, Prince Ferdinand of Brunswick, in the heat of the moment he is said to have saluted without wearing his headdress, having lost it earlier. When the Marquess of Granby became the Colonel of the Blues, the regiment adopted this tradition.
