The Household Division, except donkies, have a unique rank structure. Where the rest of the Army have Lance-Corporals who wear one chevron and Corporals who wear two chevrons, the Guards have Lance-Corporals who wear two chevrons and the rank of Lance-Sergeant who is a full Corporal but who wears three chevrons and is senior by appointment to a normal Corporal. The rank structure was appointed by Queen Victoria who stated that her Guards would not wear only one chevron when mounting guard outside the Royal Palaces so she stated that the Lance-Corporal would wear two chevrons. That left the problem of what the full Corporal would wear to show that he was a full Corporal so the rank of Lance-Sergeant was appointed. Even though the Lance-Sergeant is only a full Corporal to the eyes of outside Regiments and Corps, he still has full Sergeants' Mess privileges.
