Brotherhood of Steel



 The Brotherhood of Steel is a quasi-religious technological organization operating across the ruins of post-war North America, with its roots stemming from the American military and the government-sponsored scientific community from before the Great War. 

Origins
The Brotherhood of Steel was founded by Roger Maxson, a captain in the United States Army. Led by Colonel Robert Spindel, Maxson was part of a team sent on January 3, 2076 to monitor progress at a West-Tek facility in California, which was conducting research on behalf of the American government. On January 7, 2077, all West-Tek research and personnel – Maxson and his team included – were relocated to the newly constructed Mariposa Military Base in an effort to enhance security.

On October 10, 2077, Captain Maxson and his men discovered, to their horror, that the West-Tek scientists at Mariposa were using military prisoners as unwilling test subjects for their genetically engineered Forced Evolutionary Virus (F.E.V.). Morale in the base quickly collapsed and Colonel Spindel suffered a mental breakdown, eventually committing suicide five days later. In the midst of the crisis, Maxson's men turned to him for leadership. Captain Maxson proceeded to interrogate Robert Anderson, the chief scientist of the West-Tek research team stationed at Mariposa, learning the extent of their experiments. Anderson, along with most of his research team, were subsequently executed for their crimes.

Maxson, now in control of the base, declared his desertion from the United States Army via radio on October 20. To his confusion, he received no response from the chain-of-command, as the U.S. Army was currently focused on escalating conflicts with the Chinese. Three days later on October 23, both nations launched their entire nuclear arsenals. Within two hours, the Great War had ended and much of the Earth was reduced to a radioactive wasteland. The Mariposa Military Base survived the onslaught, its numerous safety protocols protecting the soldiers within from the radiation and the F.E.V., which had been accidentally released and was now seeping into the newborn Wasteland. Two days after the attack, on October 25, Captain Maxson sent one of his men, Platner, outside in protective power armor to scout the area and gather readings on the atmosphere. Platner reported no significant amounts of radiation in the surrounding area.

After burying the bodies of Anderson and his executed staff members, Captain Maxson and his men raided the base for various supplies and weapons schematics before sealing Mariposa and venturing off into the desert, eventually managing to regroup with surviving members, including Maxson's own wife and teenage son. The following weeks of travel inflicted casualties on the party at the hands of various raider gangs and the harsh conditions of the Wasteland. In November 2077, Captain Maxson eventually led his band of survivors to the safety of Lost Hills, a government fallout shelter. This journey came to be immortalized in Brotherhood lore as “the Exodus”.

In time, Captain Maxson set the bunker as the headquarters for his new organization, the Brotherhood of Steel. As the Brotherhood's first High Elder, Maxson sought to use Lost Hills' resources to help rebuild civilization – no matter the cost.

Early Years
Relatively little is known about the early years of the Brotherhood of Steel. In 2134, an emerging faction of the Brotherhood, led by Sergeant Dennis Allen, petitioned the Council of Elders for permission to explore the remnants of the West-Tek research facility in search of technological artifacts. In the wake of the Great War, the facility was left a highly irradiated ruin referred to by locals as “the Glow”. The Elders thus denied Sergeant Allen's request, prompting him and his followers to splinter from the Brotherhood, taking some advanced weapons and technology with them. Despite this incident, the Brotherhood of Steel continued to grow in strength under the guidance of Elder Maxson, further refining their technology and gradually forming the orders of Knights, Scribes, and Paladins that are known today. That following year, Roger Maxson died of cancer. His son, Maxson II, succeeded him as High Elder.

In the 2150's, the Brotherhood began extending their influence out into the surrounding areas, quickly asserting their place as one of the major powers of New California of the post-War West Coast. The early 50's saw the emergence of a prominent raider group known as the Vipers, who quickly established a base of operations in the badlands to the south of Lost Hills. Driven by a near-religious frenzy, the Vipers' raids become bolder and more frequent over time, eventually attracting the attention of the Brotherhood of Steel.



In 2155, the Brotherhood sent a handful of squads out into the Wasteland to track the Vipers down. To the Elders, this seemed a glorified training exercise, as they were convinced that a small detachment of Brotherhood troops in power armor would be sufficient to deal with a band of raiders, no matter how large. One Brotherhood squad, led by High Elder Maxson II himself, located the Vipers. Expecting the raiders to break and run at the sight of such a heavily armed force, Maxson did not take into account the Vipers' zeal and ferocity...or their poisoned weapons. A single arrow nicked the High Elder while he had his helmet off, leading to his death a few hours later. John Maxson, grandson of Roger, took up the role of High Elder.

In the wake of this incident, the newly appointed Head Paladin Rhombus launched a full-scale campaign against the Vipers, hunting them down and driving them to near-extinction over the course of a month. The few remaining Vipers managed to scatter north and east to the Sierra Madre mountain range. It was towards the end of this campaign that the Brotherhood sent a handful of scouts and emissaries to the Hub in order to track down these runaway Vipers. It was from these beginnings that the Hub and the Brotherhood of Steel opened full trade relations. (Caravans had delivered to the Brotherhood in the past, but in the wake of the Vipers' destruction, caravan trains now ran directly from the Hub to the Brotherhood's headquarters at Lost Hills on a regular basis.)

The Super Mutants


Several years after the Viper campaign, the Brotherhood of Steel encountered an enemy far more formidable than any band of raiders. In October of 2161, a Brotherhood patrol stumbled upon the corpse of a Super Mutant. The remains were transported back to Lost Hills for study by Head Scribe Vree.

In 2162, the Vault-Dweller arrived at the Lost Hills bunker, seeking entry into the Brotherhood. His request was not taken seriously and he was tasked with retrieving the records of Sergeant Dennis Allen's expedition from the hazardous ruins of the Glow, a fool's errand commonly used to deter would-be Brotherhood members. To the Brotherhood's surprise, not only did the Vault-Dweller return from the West-Tek facility alive, but he had also succeeded in his fool's errand and recovered a holodisk recording of Allen's doomed expedition. As a result, the Vault-Dweller became the first outsider in decades to be accepted into the Brotherhood of Steel, despite the protests of a few members.

It was from the Vault-Dweller that the Brotherhood subsequently learned of The Master's mutant army and its plans to forcibly convert the surviving human population into Super Mutants. With the support of High Elder John Maxson, the Vault-Dweller was able to convince the Council of Elders to deploy a squad of Paladins to Mariposa, where The Master's F.E.V. vats were located. With the assistance of the Brotherhood, the Vault-Dweller managed to defeat The Master and disrupt his mutant army. At this point in time, the Brotherhood of Steel stood as the most technologically advanced faction in New California. Although the remaining Super Mutants and the nascent Gun Runners had access to comparably advanced weaponry, the Brotherhood had a monopoly on power armor, supercomputers, and advanced medical technologies such as cybernetics.

Aftermath
In the wake of The Master's defeat, the Brotherhood of Steel began arguing amongst itself over the need for new recruits versus their secrecy as an organization. In the end, most of the Elders ruled against the sharing of their technology with outsiders, confident that their organization could survive on their traditional principles. The minority who opposed this ruling were sent eastward to track down the last remnants of The Master's army via a small fleet of airships. When these airships crash-landed near the ruins of Chicago, these surviving individuals founded the Midwestern chapter of the Brotherhood. In the following years, the Brotherhood continued to expand somewhat, establishing small outposts throughout California, as well as launching expeditions to regions such as Washington, D.C., and the Mojave.

In addition, the end of The Master was accompanied by the birth of the New California Republic (NCR). What began in the small farming community of Shady Sands quickly blossomed into a spirited effort to reclaim what was lost in the Great War. As the young NCR expanded, the Lost Hills region was incorporated into the growing nation in the form of the newly founded state of Maxson. While the bunker itself still remained under the control of the Brotherhood, the NCR held jurisdiction over the lands outside. Though tensions simmered between the two factions, peaceful relations remained.

The Enclave


By 2242, the Brotherhood of Steel were but a fraction of the power they had been once before. With the emergence of the Enclave, the Brotherhood found that they were no longer the most advanced faction in the Wasteland. Intimidated and lacking the resources to deal with this new foe, the best the Brotherhood could manage was just to keep an eye on the newcomers. To this end, several previously-dormant bunkers and outposts in areas of Enclave activity were reactivated.

Eventually, the Brotherhood learned of the Enclave's Vertibird technology. Lacking any similar technology of their own, the Brotherhood saw itself as vulnerable to a possible Enclave invasion. In light of this possibility, Matthew, an operative stationed in the San Francisco outpost, was requested to enlist the aid of the Chosen One to steal a set of Vertibird schematics from a major Enclave outpost at Navarro.

Although the Chosen One was successful in his mission, it is unknown if the Vertibird plans ever reached the High Council, as Operative Matthew was killed by Agent Frank Horrigan a short time after the mission's completion. However, with the destruction of their oil rig base and NCR forces subsequently hunting down remaining members, the Enclave ceased to pose a threat on the West Coast.

War with the NCR
By 2231, Jeremy Maxson had assumed the position of High Elder. Vocal in his ideas of pushing Brotherhood operations eastward, Maxson was also notably aggressive in his “hoarding” of pre-War technology. The High Elder sought to restore the Brotherhood of Steel to power by wresting any and all advanced technology from the hands of “lesser people” by any means necessary. Naturally, this led to disputes with the New California Republic, which had always been in favor of utilizing advanced technology for the benefit of society. Not long after the destruction of the Enclave, conflict erupted between the Brotherhood and the NCR.

With their superior technology, the Brotherhood managed to hold out against the NCR, even coming close to achieving total victory. However, the Brotherhood's technological advantage was gradually outmatched by the sheer size of the NCR military; no matter how many troops the NCR lost, they always seemed to have more. Meanwhile, the Brotherhood, a selective and isolationist group, lacked sorely in numbers. This discrepancy in troop numbers spelled imminent defeat for the Brotherhood.

The Mojave chapter of the Brotherhood would still be fighting the NCR as late as 2274. After establishing a base at the HELIOS One solar plant, the Mojave Brotherhood soon found itself at odds with the NCR and its growing power in the region. Eventually, the NCR sought to control HELIOS One and the Brotherhood, under orders from their Elder, refused to leave. This led to a confrontation between the two and, in typical fashion, the Brotherhood's superior technology was no match for the NCR's superior numbers, eventually losing in one of the bloodiest battles in the organization's history. With over half the chapter dead, the Mojave Brotherhood retreated to Hidden Valley, where Paladin McNamara, in light of the disappearance of Elder Elijah following the battle, took the role of Elder upon himself and placed the complex under lockdown. Since then, the Brotherhood's presence in the Mojave Wasteland has been restricted to only a few scouting missions, a point of major controversy within the chapter.

Society
The Brotherhood of Steel is a neo-knightly order that rose from the ashes of the United States military in the years following the Great War of 2077. The organization's tenets include the eradication of mutants and the veneration of technology. In recent decades, the Brotherhood has become quite reluctant in regards to sharing advanced technology with their fellow Wastelanders, whom they generally consider too ignorant and irresponsible to deserve such technology. The Brotherhood has been known to trade their technology with frontier communities and the NCR, but more often than not, they prefer to keep the more advanced material to themselves.

Ideology
Although the Brotherhood has always been portrayed as aloof, as time went on more negative aspects of their beliefs have been increasingly emphasized as their power has decreased. Originally they stood for relatively benign goals of preservation. Indeed, in one of the possible endings in Fallout; they voluntarily reintroduce technology, engage in novel research, and actively assist those inhabiting the wasteland. Later, in Fallout Tactics, the Midwestern faction eventually would go on to become a near-fascist state, but only if a specific ending is chosen in which this faction assumes the new leadership of a prejudiced General Barnaky. A different ending involves the Midwestern Brotherhood working together with the humans and non-humans of the Midwestern wasteland for the greater good, and create a post-apocalyptic utopia (however, it should be noted that none of the endings of Fallout Tactics has yet been assumed as canon, and so is open to speculation). By the time of Van Buren/New Vegas the main Brotherhood is strongly paranoid, it not only seeks to preserve technology, but actively remove it from outsiders, is disinterested in nonmilitary assets, and engages in little if any work to actually improve their tech. Much of the Brotherhood's belief system is enshrined in a document known as the Codex, which acts as an important source of information on regulations and rules that members must adhere to. The East Coast Brotherhood is different from the West Coast, seeming to want to help others instead of collect vital technology, but this created a faction focused entirely on collecting tech in the east, the Brotherhood of Steel Outcasts. The Brotherhood does also hold a religious side, with some or all members believing in a deity known as the "Creator", and often praying to the Creator, on occasions such as meals.

Symbolism of the insignia
In the Brotherhood symbol, 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.

Another interpretation is that the Brotherhood's symbol represents each of the organizations 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. This interpretation could also be supported by looking at the Outcast's insignia, which is absent of wings & shows that they do not need Elders or their equivalents.

While both the original Brotherhood of Steel in New California and the Capital Wasteland faction of the Brotherhood use different colors for different elements of the symbol (blue for the wings, gray for the sword and black for the gears), the Midwestern Brotherhood uses several mono color variations. A blue version is used by the Midwestern Brotherhood's Knights and Paladins, a black one by the Scribes and an orange one by the Elders. The golden/yellow variant seems to symbolize the Midwestern Brotherhood as a whole. The Midwestern version of the Brotherhood symbol is also reversed horizontally - the large gear is to the right of the smaller ones, not to the left as in the original.

Structure
The Brotherhood is mostly composed of the descendants of those military officers, soldiers, and scientists, but aside from some outsiders among their ranks, the Brotherhood is as close to pure-strain humanity (prime normals) that may be found outside of a Vault or the Enclave.

The ranks of the Brotherhood of Steel are generally recognized as being composed of the best and the brightest remaining to humanity, which means the BoS is a relatively small organization, at least compared to the New California Republic. They make up for this with their intimidating arsenal of pre-and-post-Great War technology: they have laser and plasma weapons, power armor, surgical cybernetic enhancements, combat implants, and Brotherhood Paladins have the ability to erase an entire town from the map without a scratch. The vast majority of BoS members are born into the Brotherhood - they very rarely accept outsiders into their ranks. While not an official policy, many members believe that in order to survive, all members are obligated to procreate. This results in a lack of tolerance for same-sex relationships, at least when the proponents of the aforementioned stance are concerned. Those born in the Brotherhood that want to be neither Scribes, Knights nor Paladins are free to leave - the Brotherhood does not believe in forcing anyone to serve them against their will. Although, members who decide to leave the Brotherhood will face the punishment of death for sharing any medical or scientific knowledge they have acquired with any outside faction.

While they have great reverence for technology, most of the Brotherhood members have little regard for non-technical fields of knowledge (and even for non-combat-related technology). Even most of the Scribes do not care about history, and some Brotherhood of Steel Initiates do not even know who Roger Maxson, the founder of the Brotherhood, was.

Divisions and locations


The headquarters of the Brotherhood is the Lost Hills bunker in California, the seat of the Brotherhood's High Elder and its ruling council, and the place where the organization was founded. It is also the center of their research and military activities. However, by 2242, the Brotherhood was spread across the wastes of California in small bunkers and installations hidden from the eyes of common folk, and finding them all and wiping them out would be a difficult and dangerous task.

Their installations include bunkers in the Den, San Francisco, and Shady Sands (capital of the New California Republic). All Brotherhood outposts are formally subject to the Lost Hills' ruling council's authority, even if they sometimes tend to act independently, especially if they are located far from California and contact with the headquarters is rare. The Lost Hills bunker is surrounded by the town of Maxson, which, while named after the founder of the Brotherhood, is officially outside Brotherhood rule and is a state of the New California Republic. The later conflict between the Republic and the Brotherhood most likely resulted in the destruction of many of the Brotherhood's bunkers in New California.

A Brotherhood bunker is located in the Hidden Valley, directly east of the settlement of Goodsprings in the Mojave Wasteland. It is surrounded by powerful underground fans that serve as a high-tech defense system, creating artificial sandstorms which allow the inhabitants to travel to and from the bunker under cover. It also serves as a kind of electronic disturbance to any and all outside factions' targeting sensors, therefore rendering the bunker safe from detection. Mr. House's calculations painted the Brotherhood insurgency to be the greatest threat to House's reign in the Mojave Wasteland in the long-term.

East Coast Brotherhood


On the East Coast, the Capital Wasteland division of the Brotherhood established a base called the Citadel, built into and beneath the ruins of the Pentagon in Washington, D.C. This faction is led by the idealistic Elder Owyn Lyons who decided to make the protection of the human inhabitants of the Capital Wasteland from super mutants and other threats his top priority, instead of the acquisition and preservation of technology. While Lyons is officially recognized by the ruling council at Lost Hills as the leader of a Brotherhood faction, because of his changed priorities he receives no support from California and his faction, for all intents and purposes, is independent. Without reinforcements from the West Coast, Lyons has been forced to recruit locally, but most new wastelander conscripts are overeager, unskilled, or both, and as a result their survival rate is atrocious. Elder Lyons’ daughter Sarah commands her own elite squad, Lyons' Pride. These soldiers help preserve the Capital Wasteland by holding back the super mutants, who tend to remain in the urban ruins of Washington, D.C.

As the war with the super mutants intensifies, the Enclave returns in the flesh after relocating from New California several years prior, their radio broadcasts having been heard for years on Wasteland radios, suddenly and ruthlessly making themselves known. In a bold first move they seize the Jefferson Memorial's "Project Purity" (a project intended to provide clean water to the wasteland), and subsequently proceed with carefully consolidating their power throughout the Capital Wasteland, while simultaneously developing a plan to systematically eliminate mutation in the wasteland. At first favoring caution, Elder Lyons soon changes his mind, engaging the Enclave in a full-scale battle after the Enclave acquires possession of Vault 87's G.E.C.K. and nearly activating Project Purity. With the aid of Liberty Prime, the Enclave is ousted from the Jefferson Memorial and into uncertain disarray. After the events of Broken Steel, the Capital Wasteland chapter has become as powerful and well-equipped as their fellow chapters back west, possibly even more so.

There are members of Lyons' expeditionary force to the East Coast who preferred to stay faithful to the Brotherhood's original goals of locating and preserving technology and knowledge. These members of the Brotherhood left the Citadel to take up residence in Fort Independence, and stylized themselves as the Brotherhood Outcasts. In addition to carrying out Lyon's original orders, the Outcasts are also trying to re-establish contact with the western Elders, and have Lyons placed in front of a firing squad.



Midwest Brotherhood
The Midwestern branch, a splinter faction which lost contact with the Brotherhood leadership at Lost Hills has been an independent organization since the 2160s, when the airships of its founders crashed near Chicago. Unlike the original, isolationist Brotherhood, this faction rules over a large part of the area between the former states of Illinois and Kansas and drafts tribals from villages under Brotherhood protection into its ranks. While more open to the outside world, this faction of the Brotherhood is by no means altruistic - the villagers under Brotherhood rule, while protected from raiders and mutants, live in fear of the infamous Brotherhood Inquisitors. The Midwestern Brotherhood main bases were bunkers that were probably pre-Great War military bunkers that were found, taken, and rebuilt. They are called Bunker Alpha, Bunker Beta, Bunker Gamma, Bunker Delta and Bunker Epsilon. The Midwestern Brotherhood power armor is very similar to the advanced power armor Mk II, and may be a variant of it.



Texas Brotherhood
After the death of John Maxson, Rhombus, the head of the Brotherhood's Paladins, became the new High Elder. After the death of the Master, the Brotherhood of Steel helped the other human outposts of New California drive the mutant armies away with minimal loss of life on both sides of the conflict. However, a super mutant faction under the leadership of Attis moved east and attempted to recreate the mutant army in Texas using the Secret Vault. Rhombus, despite some criticism from the ruling council of the West Coast Brotherhood of Steel, started a crusade against the still existent threat of the super mutant army, now led by Attis. They traveled eastward to Texas. There, he discovered a prototype Vault which was abandoned and installed the Brotherhood's main base of operation in this area. Their principal mission was to eradicate the menace of all super mutants. For this reason, they created a new Texas Brotherhood icon, which featured a pair of wings, topped by dual pistols, all of a red color.

Montana Brotherhood
A branch based in a large bunker exists in Montana, and as of 2277 is led by an Elder Patrocolus.

Commonwealth Brotherhood
A chapter of the Brotherhood exists in the Commonwealth, although not much is known about it other than it has access to vertibird technology much like its counterpart in the Capital Wasteland.

Military
The Brotherhood of Steel has characteristics similar to that of today's military such as standard armor (T-45d power armor or T-51b power armor), standard weapons (laser rifle and the laser pistol), standard ammunition (microfusion cells, small energy cells and electron charge packs). They also have training similar to that of recruit basic military training and trade training, have a chain of command, various bases, supply their own troops and have distinct branches/trades (i.e. Paladins and Scribes) that cover combat and support roles within the organization.

Ranks
The Brotherhood of Steel is organized into different ranks: Initiates are trainees who are expected to perform well enough in the training process to be promoted to Senior Initiates, and later to Apprentices. After proving themselves, Apprentices are promoted to the rank of Journeyman Knights or Scribes. The next rank is Knight Sergeant/Senior Scribe, Knight Captain, and finally the leader of each of these orders is the Head Knight and the Head Scribe.

Brotherhood Scribes are responsible for investigating and reverse-engineering the ancient technologies, maintaining the current technology of the Brotherhood and even experimenting with new weapons and other useful devices. Scribes rarely leave the safety of the Brotherhood's bunkers and outposts, but they are sometimes called into the field to examine a piece of technology or perform a task beyond the skills of the Brotherhood's soldiers.

Brotherhood Knights are responsible for manufacturing the weapons and other pieces of technology used by the Brotherhood, although they also take part in combat activities. After many years of service and experience, the best Knights are promoted to Paladins - the pinnacle rank of the Brotherhood military. Paladins are in charge of all security and outside activities. The Paladin ranks are Junior Paladin, Paladin, Senior Paladin, Star Paladin and Head Paladin. Paladins who survive to their later years become Elders, and they make up the Brotherhood's ruling council. Among this branch of the Brotherhood an additional rank, Sentinel, exists between Paladin and Elder. The leader of the council and the Brotherhood itself is the High Elder, usually descended from the Maxson family.

Relations with the outside
While they are generally not hostile to others without a good reason, members of the Brotherhood are not interested in justice for the obviously weaker and less fortunate wastelanders around them. They largely focus on keeping their secrecy and preserving and developing technology, which they often put above human life since technology is irreplaceable in the post-nuclear wastelands—lives are not. Their motives are often unclear, and Brotherhood members are not people to be trifled with. It is safe to say, however, that if a group of Brotherhood Paladins appears to be helping outsiders, their motives are not altruistic.

The Brotherhood does not like to share their choicest technological bits with others, despite the obvious benefits their technology could bring to the Wasteland. It is a commonly accepted truth within the Brotherhood that the people of the Wasteland are not responsible enough to use (and maintain) all of the technology they have at their disposal. They are known for trading some of their technologies with frontier communities and the states of the New California Republic in exchange for food and other resources, but they keep the more sensitive and advanced technologies to themselves.

Attitude towards mutants
The Brotherhood's attitude towards mutants ranges from dislike (e.g. in the case of ghouls) to outright hostility (in the case of super mutants). Early contact with the Master's super mutants was mostly hostile, and the BoS helped drive the majority of the mutant armies away from California. The Brotherhood grew angry when various salvaging operations began in the Glow, a location which the Brotherhood came to regard highly both for their fallen comrades and the pre-Great War technology located there, with Dayglow ghouls at the forefront. Most Brotherhood members came to see ghouls as filthy scavengers. In the years after the Master's defeat in New California, many super mutants settled peacefully among humans and the Brotherhood was no longer hostile to them.

Technology
Military technology is the Brotherhood's main priority, and their efforts over the centuries have equipped them with a powerful array of power armor, energy weapons, defense turrets, combat implants, and computers. Their devotion to the cause of collecting technology is such that they are willing to go to war in order to obtain it, even against much larger organizations such as the NCR.

Although less advanced than the Enclave, Brotherhood soldiers are generally equipped with Energy Weapons and suits of Power armor, usually either the T-51b or T-45d models, both of which were designed before the Great War. Recon armor is also widely used, primarily by scouts, knights, and initiates. In addition, the Brotherhood has access to some of the best medical technology available in the post-war world, and other technologies such as cybernetics and surgical implants.

The Brotherhood also has access to advanced computers which they have found in various military bases and Vault-Tec Vaults such as the Lost Hills bunker, the ruins of the Pentagon, Bunkers Alpha, Beta, Gamma, Hidden Valley and the Vault prototype.

They also possess heavy duty combat robots that have assisted them in battle, like the intimidating sentry bots, and even a 40-foot Communist-hating metal giant in the hands of the Capital Wasteland detachment.

Development
The Brotherhood of Steel were based on a completely hostile faction known as the Guardians in the 1987 game Wasteland which is known to be the predecessor to Fallout.

Appearances
The Brotherhood of Steel appears in all Fallout games to date.
