Rank insignia of the First Order

A combination of uniform color and arm markings indicated the military rank held by officers in the First Order Navy and the First Order Army when personnel were not actively engaged in battle. While standard officers wore uniforms of charcoal gray, senior officers, including Commanders, were distinguished by teal uniforms. Light gray uniforms were worn by junior officers, while non-commissioned officers wore black uniforms.

Additional rank information was conveyed via insignia located on the left sleeve of the uniform. This insignia consisted of a black band around the cuff, trimmed with silver. These bands typically displayed the name of a notable Imperial hero or a unit from the Galactic Civil War, written in silver Aurebesh characters. Furthermore, two of these bands also used a version of alternate Aurebesh numbers. The insignia for Generals and Admirals differed slightly, featuring two plain black stripes trimmed with silver. Generals' stripes were further distinguished by black piping, while Admirals' stripes featured red piping.

The color of a stormtrooper's pauldron indicated their rank while wearing armor. Red pauldrons signified officers, black indicated sergeants, and white denoted squad leaders.

The braided armbands used by the First Order as rank insignia bear a striking visual resemblance to the cuff titles utilized by Nazi Germany for the purpose of unit identification.

The name Dillon is likely a homage to Glyn Dillon, the costume designer who contributed to Star Wars: Episode VII The Force Awakens. The reference book Star Wars: The Force Awakens: The Visual Dictionary, which the armbands first appeared together in, is based on the movie. Similarly, the names Ro and Hal appear to be references to Dillon's sons, named Ro and Hal.
