also had its master gunners in three classes, but these were technical specialists and not normally seen in the field. The Royal Arms within a wreath is the badge of rank for a conductor, the most senior of all WO1 appointments, confined to the Royal Logistic Corps and held by fewer than twenty people as of 2004. From 1938, there was also a rank of warrant officer class III. The only appointments held by this rank were platoon sergeant major, troop sergeant major, and section sergeant major. The WOIII wore a crown on his lower sleeve. The rank was placed in suspension in 1940 and no new appointments were made, but it was never officially abolished. From 1938 to 1947 all WOII ranks wore the crown in wreath rank now worn by regimental quartermaster sergeants. The grades of lance-sergeant and lance-corporal were not strictly ranks but were appointments, held by selected corporals and privates, and usually carrying extra pay. The appointment was made by the man's commanding officer and could be taken away by him for disciplinary reasons, unlike full sergeants and corporals who could only be demoted by order of a court-martial. It is only since 1961 that lance-corporal has been a separate rank in its own right, and the appointment of lance-sergeant was discontinued in 1946, except in the Foot Guards and Honourable Artillery Company (and its equivalent, lance-corporal of the horse, in the Household Cavalry). Ranks General rank information Variants As most units in the British Army have long traditions (some dating as far back as the 1600s) some variation has developed in the terminology and insignia used for non-commissioned ranks, most notably in the Foot Guards and Household Cavalry. Many units do not use the rank "Private", using instead: "Trooper" in many regiments with a cavalry tradition and in the Special Air Service "Airtrooper" in the Army Air Corps "Sapper" in the Royal Engineers "Craftsman" in the Royal Electrical and Mechanical Engineers "Guardsman" in the six Foot Guards regiments "Gunner" in the Royal Artillery and Royal Horse Artillery "Fusilier" in the Royal Regiment of Fusiliers, Royal Welsh and The Royal Highland Fusiliers, 2nd Battalion, The Royal Regiment of Scotland "Rifleman" in The Rifles and the Royal Gurkha Rifles "Kingsman" in the Duke of Lancaster's Regiment "Signaller” in the Royal Signals “Ranger” in the Royal Irish Regiment, London Irish Rifles and the Ranger Regiment "Highlander" in The
