A leading rate is permitted entry into and full use of the corporals' mess when visiting other service bases.
[1] The insignia worn by a leading rate is a single fouled anchor on the left arm, when in dress uniform, No.2s or "Tropics".
It also appears on the left arm of the white front[clarification needed] (before the introduction of short sleeved shirts for all ratings) or overalls.
Until 2017, a "hook" was worn on each shoulder epaulette, when in working rig, woolly pully or burberry.
This led to the slang term killick or hooky used in reference to this rate.
