Notes
The Good-Conduct stripe was a British Army award for good conduct during service in the Regular Army by an enlisted man. The insignia was a points-up chevron of NCO's lace worn on the lower sleeve of the uniform jacket. It was given to Privates and Lance Corporals for 2, 6, 12, or 18 years' service without being subject to formal discipline.
It granted a pay bonus as a sort of "carrot" to get non-promotable enlisted men to behave. As the "stick", a stripe would be removed for an infraction (a write-up in the Regimental Conduct Book) and a Court Martial would forfeit all of them. The soldier would then have to start from the last stripe earned and work his way up again. It was also removed upon attaining the rank of Corporal, as Non-Commissioned Officers were promoted by merit and punished by loss of rank. Source: Wikipedia
