Note: NCOs in the Imperial service have considerably more authority and responsibility than similarly-titled NCOs in the US armed services.

  • An Imperial lance-corporal leads a fireteam, making him or her equivalent to a US Army sergeant or USMC corporal.
  • An Imperial corporal leads a section (~equivalent to a US Army squad), making him or her equivalent to a US Army staff sergeant or USMC sergeant.
  • An Imperial sergeant is typically a platoon sergeant, making him equivalent to a US Army sergeant first class or USMC staff sergeant.
  • An Imperial staff sergeant is typically assigned staff or technical duties, and is roughly equivalent to a US Army master sergeant or USMC gunnery sergeant.

Note: Warrant officers in the Imperial Service are equivalent to senior NCOs in the US armed services, not to US warrant officers.

  • An Imperial warrant officer is typically the colour sergeant (senior NCO) in a company, and is equivalent to a US Army or USMC first sergeant.
  • An Imperial senior warrant officer is typically the sergeant-major of a battalion, and is equivalent to a US Army or USMC sergeant major.
  • An Imperial chief warrant officer is typically a the sergeant-major of a regiment or larger formation, and is equivalent to a US Army or USMC command sergeant major.

Insignia of rank


Other ranks’ insignia are essentially the same between the services, except that the Navy doesn't have a leadership role at the E-3 grade so there is no naval equivalent of the lance-corporal's chevron.

The Navy and Marines versions shown in the illustration depict the Naval insignia as worn on service uniform and the Marines insignia as attached to armour and fatigues. Gorgeous dress-uniform variants are not depicted. ORs’ insignia are worn on the upper sleeve of shirts and jackets, on the lower sleeve of overcoats; on fatigues and armour they are worn in the middle of the chest.

Officers’ distinction lace is shown as worn on the cuffs of Navy service and dress uniforms in the operations branch. Engineering officers, medical officers etc. wear the badge of their branch of service in place of the “Operations” star. Marines officers wear the same pattern of stripes, but in their own colours, and with their own branch-of-service insignia. Imperial civilian officers wear similar distinction lace according to the equivalency of their grade, in the colours of their services and with badges of their own services.

Officers’ military insignia are shown as worn on marines’ undress uniform epaulettes — the round thing at the top is a gold button securing the epaulette, it is not part of the insignia. The same arrangement of stars, crowns, and swords-and-batons may be painted onto armour etc, embroidered in subdued colours on rank slides to be worn in the mid-chest, or even worn as enamelled gold jewellery on dress uniforms. These insignia are not worn by civilians.

It has not escaped the attention of enlisted marines that the warrant officer’s insignia of a crown fits in neatly between the O-3 and O-4 insignia, which wags cite as evidence that the colour sergeant ranks between the company commander and the platoon commanders, even above the deputy company commander. Extrapolating, we find this consistent with the fact that the RSM ranks next after the colonel, which all tends to the conclusion that although a sublieutenant in command of a platoon outranks his sergeant, when an ensign is platoon commander the platoon sergeant outranks him. This is secret wisdom.
