The iconography of the Brotherhood of Steel is built around its emblem, featuring gears, a sword and wings. This iconography is widely used to decorate their facilities, tag armor and equipment, and as part of markers identifying their territory. The gears represent their engineering knowledge, the sword is their will to defend themselves, the wings represent the uplifting hope that the acquisition of lost technology represents for mankind's salvation following the devastation of the Great War, and the circle represents the fraternal unity that makes the organization a true brotherhood.[1]

Another interpretation is that the Brotherhood's symbol represents each of the organization's different orders. The sword represents the Paladins, the wings represent the Elders (the "wings" control the movement of the sword), the large gear represents the Knights, and the two smaller gears represent the Scribes and the Initiates, whose services keep the Knights supplied with the information and the manpower required to get their jobs done.[Non-game 1]

Insignias

The Brotherhood insignia has evolved throughout the years and while it has retained its general appearance, the number of cogs on the gears, their facing, and basic color scheme have varied between iterations. The standard is nine cogs on each wheel, at times facing interchangeably, as both left- and right-sided have been in use at the same time, specifically within the Appalachian chapter between approximately 2082 and 2095, later with the Brotherhood First Expeditionary Force in 2103, as well as the Mojave chapter in 2281.

A pattern emerges where Chapters that identify closely with the original Brotherhood of Steel based out of California (Lost Hills, the Mojave Chapter, the first incarnation of the Appalachian chapter) have the largest cog on the left (facing west) while later chapters that have migrated east (the Eastern Brotherhood, the Appalachian Expedition) have the largest cog on the right (facing east).

Decals

These stenciled Brotherhood decals are seen in the "Brotherhood of Steel, Institute, Railroad, Minutemen Weapon Paint Job" and "Brotherhood of Steel, Institute, Railroad, Minutemen Armor Paint Job" bundles on Fallout 4 's Creation Club storefront, created for Bethesda by the modder Skibadaa. The orientation of the cogs on these symbols alternates between uses. Some of the skins included in these bundles were later repurposed as Overseer rank rewards in Fallout 76's Nuclear Winter game mode. They use primarily light-grey colors with red accents and symbols.

Notes

  1. 1.0 1.1 1.2 As per the sources outlined on History of the Brotherhood of Steel, the Brotherhood's foundation was not instantaneous and the order as we know it was formally proclaimed ~5 years after Maxson's desertion.
  2. The exact timeframe that the Nuclear Winter game mode takes place in, and its relationship to the larger story of Fallout 76, is ambiguous and unclear.

Behind the scenes

Fo3 BoS Citadel flag base image

Base texture.

BoS Flag FO3

Original recreation of the flag, with the oversized sigil in a round field, more saturated colors, and only a single shade of red.

  • Shortly after the release of Fallout 3, an upscaled "clean" fan recreation of the flag flown at the Citadel was uploaded to Nukapedia. This recreation possessed numerous differences from the original texture: in addition to a more saturated color palette, the sigil was oversized (terminating on the last, rather than penultimate stripe) and placed in a circular field of the same color as the stripes. The original texture, seen to the right, used a thick, rounded outline (the result of a stroke blend effect being used when applying the sigil) in a darker shade of red. The original texture also possessed a compositional error not reflected in the recreation, where the sigil and its stroke blend were applied on top of the burlap filter used to "weather" the texture. While the altered design was eventually replaced by a more direct recreation of the texture, the original recreation was referenced by Bethesda for various pieces of merchandise.
  • Two alternative insignias for the Brotherhood can be seen in concept art for Fallout 4. Both used a skull, sword, and gear surrounded by wings. One version of this was intended to appear as a pre-War tattoo but was cut from the game.[2]
