Claim: The British Army is the principal land warfare force of the United Kingdom and one of its regiments more known by their nickname as The Blues and Royals as opposed to their original name (Royal Horse Guards and 1st Dragoons) allows troopers and non-commissioned officers to salute an officer when not wearing a headdress.
Evidence: The British Army is the principal land warfare force of the United Kingdom, a part of British Armed Forces. The Blues and Royals (Royal Horse Guards and 1st Dragoons) (RHG/D) is a cavalry regiment of the British Army, part of the Household Cavalry. Instead of being known as the Royal Horse Guards and 1st Dragoons, the regiment is known as the Blues and Royals and is therefore the only regiment in the British Army to be officially known by their nickname as opposed to their full name. The Blues and Royals is the only regiment in the British Army that allows troopers and non-commissioned officers, when not wearing headdress, to salute an officer.
