Changing of The Queen's Life Guard - 5 June 2015

Changing of The Queen's Life Guard, Horse Guards Parade, London, 5 June 2015.
On this day the Old Guard was found by The Blues and Royals, and the New Guard was found by The Life Guards. The two regiments alternate each day. During the month of July both regiments enjoy Summer Camp and the Queen's Life Guard is found by the Royal Horse Artillery.
Long Guard (the Queen in residence at Buckingham Palace), comprising an Officer, Corporal Major (carrying the Standard), two Non-Commissioned Officers, a Trumpeter and ten Troopers. When the Queen is not in residence in London, a Short Guard is deployed comprising two Non-Commissioned Officers and ten Troopers.
Early in their history, the cavalry regiments thought the term "sergeant" to be inappropriate due to it's derivation from the Latin for "servant". Consequently they do not use the term "sergeant" for rank. Corporal Majors are equivalent to Sergeant Majors in other regiments, as are Corporals of Horse equivalent to Sergeants. For the Changing of the Queen's Life Guard, the two Non-Commissioned Officers are therefore selected from the ranks of Corporals of Horse, Lance Corporals of Horse or Lance Corporals. Whilst there are several detailed differences in their uniforms, the most obvious is that Officers wear their thick gold braid aiguillettes on the right shoulder, Corporal Majors wear thick gold aiguillettes on the left shoulder, and these decrease in thickness and amount down to the rank of Lance Corporal. Troopers wear no aiguillettes.
