Brotherhood of Steel hierarchy

The Brotherhood of Steel relies on a strict hierarchy, where orders flow through the ranks and are carried out without hesitation.

Characteristics
Members of the Brotherhood are divided into distinct castes, each with a function of their own. The actual organization of the classes themselves and the ranks varies to some extent, typically by geographic region. Most follow the original regime for ranking. The Chain that Binds doctrine is traditionally intended to ensure obedience and conformity among the members of the Brotherhood, maximizing the efficiency of the Brotherhood as a war machine.

All members are subject to the same body of laws, at least in theory. Even elders may be dismissed for violating the Brotherhood's charter or laws, such as destroying technological devices without due cause, violating the Chain that Binds, or murdering a fellow member. Due to the requirement for elders to set an example, elders may also be stripped of their position if allowing them to retain it would compromise the morale or integrity of a given chapter. In practice, the law is selective, for example; High Elder John Maxson could issue direct orders to the Vault Dweller, an initiate, without consequences. Elder McNamara's violation of the Chain that Binds have also gone unnoticed, due to chapter ignorance of large parts of the doctrine.

Ranks have been separated by type of organization, using descriptive names.

Formative years
The early years saw the implementation of a provisional rank system, meant to emphasize and enforce the ideology put forward by Roger Maxson. Maxson's goals for this were two-fold: First, it would strip members of the Brotherhood of their ties to the pre-War military and government, ensuring that surviving generals or politicians would not be able to invoke their oaths and order them to, for example, unleash nuclear devastation on the world again (as was the case with Col. Ellen Santiago and Sec. Thomas Eckhart in Appalachia). Second, it would give the members of the Brotherhood an inspiring new system to believe in and dedicate themselves to, filling the void left by the destruction of civilization as they knew it. Inspiration came from the fall of the Western Roman Empire, when knights and scribes maintained order and preserved knowledge after the empire collapsed. By June 20, 2082, all members under his command had switched over to using Brotherhood ranks and practices, both in New California and Appalachia.

As the initial founders of the Brotherhood were predominantly military personnel, the proto-Brotherhood continued to use their existing Army ranks for several years, and even once the new ranks were implemented, civilian auxiliaries were treated with a certain degree of patronizing contempt.

One of the unique parts of this early model was the rank of a squire, granted to new recruits regardless of age. Overall, the response to the new system was mostly positive, though there were some reservations within the organization, especially among veterans of elite units like the Army Rangers. To some, ranking grown men and women using the term "squire" - one that traditionally referred to young nobles no older than children - was considered insulting by ranking members. Senior Knight Ted Wilson persuaded Maxson to change it, although the modifications were mostly not introduced by the time Appalachia was cut off from the west.

Lost Hills model
The structure of the early years was modified and expanded to accommodate the growing numbers of the Brotherhood, culminating in the creation of what is best termed the old or classic model. It is the oldest stable type of organization, followed by the founding chapter at Lost Hills and affiliated chapters, such as the Mojave chapter. "The ranks of the BOS is generally recognized as being composed of the best and the brightest... which means the BOS is a really small organization, at least compared to NCR. They make up for this with their frightening arsenal of pre-war and post-war technology: They have laser weapons, power armor, surgical enhancements, combat implants, and a squad of Brotherhood Knights have the ability to erase an entire town from a map without a scratch." "The Brotherhood are generally good guys, but they have their faults - (1) they don't care for mutants, (2) they worship technology, and in many cases, put it above human life, and (3) they don't like to share their choicest technological bits, despite the obvious benefits their technology could bring to the wasteland. It's commonly accepted within the Brotherhood that the people of the wasteland are not responsible enough to use (and maintain) all of the technology the BOS has at their disposal. They are known trade some of their technologies with frontier communities and NCR states, but they keep the more sensitive technologies to themselves." "It is believed that the current HQ of the BOS is the Lost Hills bunker in Fallout 1, but at the time of Fallout 2, the BOS is spread across the wastes in small bunkers and installations hidden from the eyes of common folk – finding them all and wiping them out would be a difficult and dangerous task." ''"The BOS is divided into different ranks: Initiates are trainees who are expected to perform well enough in the training process to be promoted to Squires. After proving themselves, Squires are promoted to Knights. After many years of service and experience, the best Knights are promoted to Paladins - the pinnacle of the Brotherhood military. Paladins who survive to their later years become Elders, and they number among the Brotherhood ruling council.""It is also possible to serve the Brotherhood as a Scribe. Scribes are responsible for copying the ancient technologies, maintaining the current technology and even experimenting with new weapons and other useful devices. Scribes rarely leave the safety of the BOS bunkers, but they are sometimes called into the field to examine a piece of technology or perform a task beyond the skills of the Brotherhood soldiers.""It is said that the BOS symbol, broken down, represents each of these 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 Squires, whose services keep the Knights supplied with the information and the manpower to get their jobs done. No one is sure what the circle means, however."''
 * 1) Initiates are the youngest and/or least experienced members of the Brotherhood, whose sole purpose is training and learning to become a valued member of either the knights or the scribes. Although not expected to make the choice until later in their lives, initiates may select to study towards becoming a knight or scribe early on, and be referred to as an initiate scribe or knight. Initiates are first promoted to senior initiates, and later to apprentices in their chosen Order, the aforementioned Knights or scribes. The choice is not set in stone and the member can transfer between orders until they complete their apprenticeship and become eligible for advancement. After completing their training, apprentices are promoted to journeyman knights or scribes.
 * 2) Scribes are scientists, responsible for researching and reverse-engineering recovered technologies, maintaining the Brotherhood's scientific knowledge and even experimenting with new ones (though the Brotherhood's focus on preservation means this is rare).   Scribes rarely leave the safety of the bunkers, but they are sometimes called into the field to examine a piece of technology or perform a task beyond the skills of the Brotherhood soldiers. Due to their stationary duties, scribes typically staff medical facilities, responsible for intensive and long-term care of Brotherhood members.Fallout Bible 6: "The Brotherhood of Steel: The Brotherhood of Steel (BOS) is a techno-religious organization, with roots in the US military and government-sponsored scientific community from before the war. The BOS is mostly composed of the descendents of those military officers, soldiers, and scientists, but aside from some outlanders among their ranks, the BOS is as close to pure strain humanity (prime normals) as you're going to find outside of a Vault."
 * 1) Knights are the craftsmen and foot soldiers of the Brotherhood. They maintain the Brotherhood's stockpile of technology, repairing and providing technical services where they are needed, as well as producing new weapons to replenish stocks and provide trading goods. Knights also perform patrols, scouting assignments, and support paladins in offensive operations. When too few paladins are available on an expedition, knights may also take on a combat role. Those that focus on combat training may be eligible to then become paladins.
 * 2) Paladins are the primary combat force of the Brotherhood, in charge of all security and outside activities. Equipped with the best military technology the Brotherhood has to offer, they are some of the most fearsome warriors in the wasteland. The ranks of the paladins are reinforced by promoting exceptional knights and it is highly improbable to become a paladin any other way. While power armor was reserved primarily for paladin use in the first century of the Brotherhood's existence, exceptions existed, allowing knights and in extreme cases even initiates to use power armor (usually older models, such as the T-45).
 * 3) Elders are the highest-ranking members of the Brotherhood, its leaders and decision-makers, determining everything from meals to the course of campaigns. Typically, only paladins are eligible to become elders, but exceptions can be made for extraordinary members of other branches. Regardless of their branch of service, elders are elected into the council by its members, with its head, the high elder, also elected by the council. The candidate can turn down the offer. Out of the first four high elders, three belonged to the Maxson lineage, but there is no requirement for the council to propose the position to a member of the bloodline.

Lyons model
The Lyons model was introduced in the D.C. bunker known as the Citadel in response to the challenges encountered in the Capital Wasteland and opening up the ranks once more to local recruitment. Lyons' representatives regularly made recruitment runs in the Capital Wasteland, sponsoring volunteers for induction into the Brotherhood ranks. The formation of the Outcasts in 2276 forced Lyons to suspend the sponsorship program and accept recruits as they came, leading to an influx of unskilled, but overzealous soldiers into the ranks.
 * 1) Squires are children born into the Brotherhood of Steel, who begin their training, and indoctrination, as squires. Under Lyons' command, the only squire at the Citadel was the young Arthur Maxson.
 * 2) Initiates are the newest and/or least experienced members of the Brotherhood. Although their usual purpose is training and learning to become a valued member of either the knights or the scribes, manpower shortages forced Lyons to deploy them in combat roles - with predictably disastrous results.
 * 3) Scribes are scientists, responsible for researching and reverse-engineering recovered technologies, maintaining the Brotherhood's scientific knowledge, and even experimenting with new ones (though the Brotherhood's focus on preservation means this is rather rare).  There are three scribe orders within the Brotherhood, focusing on different types of technology: the Order of the Sword (offensive), the Shield (defensive) and the Quill (civilian). One major difference from the Lost Hills model is that scribes are also responsible for manufacturing and engineering activities of the Brotherhood, a function originally reserved for knights.
 * 4) Knights and paladins are responsible for security, logistics and combat operations, forming a single, continuous hierarchy, which reflects Lyons' professed proactive focus. While power armor was primarily reserved for paladin use in the first century of the Brotherhood's existence, Power armor usage among knights under Lyons' was the norm, rather than an exception. However as under Lost Hills, initiates only used power armor under certain exceptional cases.
 * 5) Elder is the highest-ranking member of the chapter, its leader and decision-maker, determining everything from meals to the course of campaigns. Elder Owyn Lyons (Star Paladin at the time) received a field promotion to the rank of elder and remained at the head of the chapter for over twenty years until his death circa 2278. His daughter Sentinel Sarah Lyons was promoted to elder after.

Maxson model
The Eastern division represents an evolution of the Lyons model, adapted to the greatly expanded reach and power of the Brotherhood in the East.

The Brotherhood actively recruits wastelanders, in stark contrast to western chapters. Elder Arthur Maxson continued Lyons' practice, including and expanding sponsorship. All adult recruits have to be sponsored by existing Brotherhood members (usually paladins), who would travel with them and teach them the ideals of the Brotherhood and train them in combat. To this end, active members can promote recruits to initiate rank in the field, but the rank and subsequent promotions have to be confirmed by the elder at the earliest possible opportunity. However, while the member can retract their sponsorship, once the rank is confirmed by the elder, only the elder can dismiss the sponsored party from the organization. Those born into the Brotherhood receive the rank of squire and on becoming an initiate will then join one of the services, much like those who have been sponsored and recruited.

There are three main paths an initiate can take: ground combat (knights and paladins), air combat (lancers), or research and engineering (scribes). Kells: "First and foremost, I wanted to inform you that using the Minutemen to destroy the Institute was a risky venture at best. Using untrained non-military personnel in the operation could have had devastating consequences and resulted in an unnecessary loss of life. In the future, Elder Maxson and I need you to approve any tactical changes before they're executed. As I expect Elder Maxson has already explained, the destruction of the Institute is simply the first stage of our operations in the Commonwealth. There are still Super Mutants and ferals to be dealt with as well as any remaining synths that escaped the blast. It's our hope that you'll continue serving with the Brotherhood and assist us with eradicating these threats." The Sole Survivor: "Of course, Captain." Kells: "Very good Paladin." Arthur Maxson: "In light of your service, Captain Kells and I both feel you deserve unique recognition for your contributions, both past and future. It's with great pleasure, and the utmost respect that you are hereby granted the title of Sentinel. This is the highest honor a Brotherhood soldier can achieve, but we both felt strongly that it was well deserved." Kells: "In addition, we'd like to present you with this jetpack modification for your power armor. The Brotherhood has few of these devices in its possession, but we feel you've earned the right to utilize one of them. Congratulations, Sentinel. It's an honor to be serving with you." The Sole Survivor: "Would I be the only Sentinel in the Brotherhood?" Arthur Maxson: "In our division, yes. There hasn't been a Sentinel serving under me for many years now. It's a position that commands a great deal of honor and respect, so I do not award it lightly." The Sole Survivor: "Thank you both. I'm really quite honored." Arthur Maxson: "The honor is ours. So, Sentinel... for the first time since we've met, I have no orders for you. From this moment forward, you will decide which missions you undertake and how you will guide us. Captain Kells and the personnel at the Cambridge Police Station still possess numerous operations for you to undertake. Where you go from here is up to you. Ad Victoriam, Sentinel." (Arthur Maxson's and Kells' dialogue)
 * The ground combat path begins with the rank of an initiate, who then becomes an aspirant. After completing their training (or initiation), the aspirant becomes a full knight and receives the right to wear power armor. The knight then continues their work and training to attain knight command ranks and then become a paladin. Knights comprise the bulk of the Eastern division's ground force and are the backbone of their military. Paladins are veterans who represent the most skilled ground soldiers the Brotherhood has at its disposal. They are also expected to be a symbol of integrity and set an example for other troops. Paladins are usually deployed as field commanders or head special operations in the field, such as reconnaissance or delicate tech recovery. The eastern division of the Brotherhood also retains a special rank: sentinel. It is a rare and illustrious rank given to the east coast brotherhoods most distinguished and experienced soldiers. Those who possess this rank do not require orders and usually conduct operations at their own discretion, answering directly to the elder. The rank was rarely awarded; by October 2287 no sentinels had existed in the Brotherhood for many years. Arthur Maxson: "Paladin, I'm pleased you've returned. Captain Kells and I wanted to speak with you. Captain Kells."
 * The air combat path the newest addition to the Brotherhood hierarchy. Its members are granted lancer ranks, and are responsible for piloting The Prydwen and the Brotherhood's fleet of vertibirds. The ranking structure is similar to that of the ground combat path knights, although the rank of lancer-captain is the highest rank. Several lancer-captains are stationed in the Commonwealth and can be found aboard the Prydwen or piloting vertibirds, but they report to Lancer-Captain Kells who is the second in command to Elder Arthur Maxson and captain of the Prydwen.
 * The research and engineering path consists of those who pursue the path of a scribe. Scribes are split into three distinct Orders: the Order of the Sword, the Order of the Shield, and the Order of the Quill, which are responsible for the research and maintenance of weapons, the research, and maintenance of armor and for history, record keeping and non-combat technology respectively. Each order is led by a proctor who consults with the head scribe and the elder on certain issues. Unlike the western chapters or Lyons, the Eastern division also assigns scribes to field operations. Field scribes are trained in rudimentary combat to bolster their skill set and make them a powerful asset to any Brotherhood unit in the field.

All members of the Brotherhood answer to the elder. An elder is either voted in by the chapter or promoted by the elder council from Lost Hills. As of 2287 the elder of the East Coast Chapter of the Brotherhood of Steel is Arthur Maxson, the last known descendant of Roger Maxson, the founder of the Brotherhood.

High elder
The high elder is the leader of the entire Brotherhood of Steel and the other elders. High elders may also be addressed as generals, as an honorary title.

Known high elders:
 * Roger Maxson (2077 - 2135)
 * Maxson II (2135 - 2155)
 * John Maxson (2159 - ?)
 * Rhombus (? - 2208)
 * Jeremy Maxson (ca. 2231 - ?)

Elder
The elders form the Brotherhood's ruling council. Individual elders are occasionally leaders of localized chapters of the Brotherhood. Under normal circumstances, the ability to become an elder is reserved for paladins, although there are exceptions, such as Elder Elijah, who was a scribe.

Sentinel
Sentinel is a rank used by the East Coast division, ranking between star paladin and elder. Sentinels do not require specific orders and usually conduct operations at their own discretion, with the elder issuing only standing, high-level orders. Sentinels are appointed directly by the chapter's elder, acting as an extension of their will. There is no requirement to appoint a sentinel and many chapters can go for years without one.
 * In Fallout 3, the only sentinel is Sarah Lyons, who leads the Lyons' Pride elite unit.
 * In Fallout 4, the Sole Survivor can also attain this rank if they complete the Brotherhood main questline, becoming the first sentinel of the eastern division in years.

Paladins
"A Paladin must be a leader first, and a person second."

- Knight Daniel Shin

Head paladin
The main commander of the paladins, responsible for overseeing their operations and training them. The head paladin may induct other members of the Brotherhood into the paladins at their discretion, depending on their aptitude.


 * John Maxson was the head paladin of Lost Hills before he accepted the post of high elder in 2155. He was replaced by Rhombus.
 * Nolan McNamara was the head paladin of the Mojave chapter until 2276. After the disastrous Operation: Sunburst, he became elder, with Edgar Hardin appointed head paladin.

Senior paladin
Senior paladins are paladins that show promise to become paladin commanders, paladin lords, or head paladins. They are well respected among other paladins and knights and can increase the morale of soldiers greatly.


 * Senior Paladin Talus, Lost Hills, 2161
 * Senior Paladin Ramos, Mojave, 2281
 * Edgar Hardin was a senior paladin during Elder Elijah's reign.

Star paladin
Star paladins are paladins who have been recognized by the Brotherhood for their honor, loyalty, and tenacity in battle. They are given far more freedom (similar to sentinel) in how they conduct operations, although not as much as a sentinel would.
 * In Fallout 3, there is only Star Paladin Cross, appointed by Elder Lyons. Lyons himself was a star paladin before he was promoted to elder.
 * In Fallout 4, star paladins can be seen guarding Liberty Prime's construction platform, and they can be seen out in the field at checkpoints in the southern area of the Commonwealth if the Sole Survivor has completed Ad Victoriam. Star paladins continuously level with the player character.

Paladin commander
Paladin commanders are unit leaders in the Eastern Division and are well respected among the Brotherhood's ranks. They are scarcely found in the field, often planning with the other commanders in the Brotherhood, but when they are, they are a force to be reckoned with, often found with powerful energy weapons and leading huge forces. They rank only below star paladin, sentinel, and elder.

Paladin
Paladins are a class of members of the Brotherhood of Steel. They are likened to the scribes of the Brotherhood as being on the same level, but with a different purpose. They are the protectors of the Brotherhood, fighting and protecting its interests across the wasteland, equipped with power armor and an array of lethal weapons.


 * In Fallout: New Vegas, the Courier is promoted to paladin after Eyesight to the Blind or Tend to Your Business is complete.
 * In Fallout 3, paladins are ranked above knights.
 * In Fallout 4, paladins are both veteran fighters and commanders, as denoted by their black power armor and second red stripe on the armor's left forearm.

Head knight
The commander of the knights, in charge of all their operations. The Brotherhood allows for positions to be combined, and one person can be both head knight and head paladin.


 * In Fallout, Rhombus is the head knight.

Knight commander
Knight commanders are often seen in the field leading shock troopers dropped off of Vertibirds, or in charge of a command post in the Commonwealth, leading lower ranking knights into battle. They are the highest ranking knights in the Brotherhood.

Knight captain
Knight captain is a rank used by the East Coast division.


 * In Fallout 3, there are four known members of the Brotherhood who have achieved this rank, Dusk, Gallows and Colvin from Lyons' Pride as well as Knight Captain Durga. Knight captains can be seen holding staff jobs as well as command positions.
 * In Fallout 4, there are several knight captains around the Boston Airport and the Prydwen area as well as appearing in the field with other Brotherhood soldiers. Two of them are Cade, the ship's medical officer, and Larsen who is sent to clear out Acadia if the Sole Survivor informs the Brotherhood of its existence in Far Harbor.

Knight sergeant
Knight sergeant is a rank used by the East Coast chapter, denoting a position below knight captain. The rank gives command of one or two squads of knights, as well as the command of a base or outpost like the GNR building plaza,
 * In Fallout 3, Knight Sergeant Wilks is the only knight sergeant.
 * In Fallout 4, knight sergeants are numerous, but unnamed, with the exception of Knight Sergeant Gavil who is in charge at the Boston Airport supply depot, and the mentioned-only character Knight Sergeant Dawes.

Senior knight
Experienced knights may be promoted to a position of seniority, overseeing the activities of their juniors.
 * In Fallout: New Vegas, Senior Knight Lorenzo is the head of the knights at the Mojave chapter and answers directly to the Elder.
 * In Fallout 76, Senior Knight Ted Wilson was in charge of training at Camp Venture prior to its abandonment, before ultimately perishing at Fort Defiance during the Brotherhood's final stand in Appalachia.



Journeyman knight

 * This rank is typically referred to as just Knight

Knights are responsible for manufacturing and repairing the weapons and other pieces of technology. After many years of service and experience, the best knights are promoted to paladins, the pinnacle of the Brotherhood military. The next rank is senior knight, and finally, the leader of the order is the head knight.

In the East Coast chapter, "knight" is a strictly military rank and the scribes are the ones responsible for manufacturing technology there.


 * Knights appear in every game in some form or another.
 * In Fallout, Anthony and Paul are described as a journeyman knights under their IDs.
 * In the Broken Steel add-on for Fallout 3, The Lone Wanderer becomes a knight after the quest Take it Back! is completed Although knights are typically required to train as initiates, it appears that this can be waived at the elder's discretion as Elder Lyons directly appoints the Lone Wanderer as a knight. Lyons even states that he will "circumvent our standard recruitment procedures" in the Lone Wanderer's case.

Aspirant
The rank of aspirant was created by the East Coast Chapter of the Brotherhood some time between 2277 and 2287, denoting an initiate who has entered training under a superior officer, such as a paladin or knight-commander, in order to be promoted to a full-fledged knight.

Squire
By 2277, the East Coast chapter of the Brotherhood has adopted the rank of squire as a title for children who have been born into, or been recruited by the Brotherhood, making it the lowest rank in the chapter. These children are not permitted to take part in combat. Instead, they perform errands and menial labor for the Brotherhood's military and are provided with training and education in return. They also appear to be heavily conditioned by propaganda, with those aboard the Prydwen claiming not to fear death and possessing an almost religious devotion to the Brotherhood. Upon reaching adulthood, squires become initiates and begin active duty.

Squires are occasionally taken out as observers on a sweep and clean mission led by high ranking members of the Brotherhood. Lancer Captain Kells bestows such a responsibility upon the Sole Survivor in the radiant quest Leading by Example. The squire that accompanies the player character does not take part in the fighting and is merely there to observe and study combat techniques.

Senior initiate
Senior initiates are initiates who have completed basic training and move on to more advanced training.

Initiate
Initiate is one of the lowest ranks in the Brotherhood of Steel's rank system. The precise definition of the rank appears to vary between the regional chapters.

The West Coast division uses the term to indicate a mere trainee as having been initiated into the Brotherhood, whereas the other two reserve that title until the recruit has completed initial training. The most plausible explanation lies in the fact that the West Coast division is significantly more insular than the others; the bulk of its new recruits are the offspring of existing members and only rarely are outsiders accepted into the organization. By contrast, circumstances have forced the other two divisions to actively recruit from among the local population.

The West Coast chapters divide the rank into "buck" initiate and senior initiate, while the East coast only has a single initiate rank.

In the West Coast division, initiate is the base rank of one who has only just been accepted into the Brotherhood as a trainee. After completing initial training, initiates are promoted to apprentice, like Apprentice Watkins. Apprentices who are at the stage of choosing their career path then becomes a journeyman, but must choose which order of training they wish to receive; either scribe or knight.

Initiates may even be issued power armor if their assignment merits it as in the case of Cabbot outside the Lost Hills Bunker, or the ill-fated Initiate Reddin of the Lyons' Pride. These are uncommon cases however. In some chapters, such as under Arthur Maxson's east coast division, or the Mojave chapter, initiates are never seen wearing power armor and are instead wear Brotherhood fatigues or recon armor.

Overview
 Scribes are tasked with creating and keeping records of the technology recovered and used by the Brotherhood and experimenting with new weapons and other useful devices to be used in the field by the Knights and Paladins. Scribes rarely leave the safety of the BoS bunkers, but they are sometimes called into the field to examine a piece of technology or perform a task beyond the skills of the Brotherhood soldiers. The attitude of many scribes in the Brotherhood can be described as techno-centric. While a great number study history and cultures, the majority of scribes focus their studies on subjects related to the acquisition, repair, or creation of technology.

There are three major Scribe orders: Each is headed by a Proctor, designated by the Head Scribe.


 * is responsible for weapons research and development. Guns, ammunition anything of an offensive nature.
 * is responsible for defensive research. Power Armor, defensive structures, anything that is intended to protect.
 * preserves the written knowledge of the ancients, seeking out all manner of books and holotapes. 

Head scribe
The head scribe is the highest-ranking civilian class of the Brotherhood of Steel. The head scribe is responsible for choosing which scribes work on which project and which scribes should be assigned to each order. The head scribe also chooses the proctors of each order and must also oversee the projects each order is working on. The head scribe is a highly intelligent person who has mastered the orders of the Sword, Shield, and Quill, and may also take on a project of their own interest, as Head Scribe Rothchild did with the Liberty Prime project. The head scribe is one of the people who must attend the meetings with the high elder, elder council, generals, head paladin, and head knight. The head scribe reports to the high elder and Elder Council only.

Proctor
The proctors oversee and approve of each project that the scribes in their order are working on, and assign the proper scribes to the right projects. Each proctor must report to the head scribe, which assigned them to their respective order, on each project, and to get approval to move ahead with a new project. They often work on their own projects, which are usually completed very quickly because the proctor can prioritize them and assign senior scribes to them.

In 2277, there were three proctors in the Capital Wasteland region. Peabody, Order of the Sword, Elizabeth Jameson, Order of the Quill, and Bowditch, Order of the Shield.

In Fallout 3, proctors are not actually ranks but rather roles taken on by certain scribes. As of the events of Fallout 4, however, proctors have become a rank of their own, superior to senior scribes.

Senior scribe
Senior scribes are some of the most advanced scribes. They are always chosen for the most important projects and are the next in line to become proctors of orders when the old proctor retires or dies. They often take on the most promising journeyman scribes to be their apprentices and choose what order they should be in (usually, it is the same order that the senior scribe is in). Senior scribes teach their apprentices everything they know and will continue to teach them until they are nearly senior scribes themselves. On rare occasions, the senior scribe will be promoted to head scribe and their apprentice to proctor. When this occurs, the apprentice will be given special treatment and the elders usually separate the two to remove any impression of impropriety. Three examples of senior scribes are Linda Schuler, from the Mojave Brotherhood of Steel, and Yearling and Neriah, from the East Coast Brotherhood of Steel.

Journeyman scribe

 * This rank is typically referred to as just Scribe

Scribes are tasked with creating and keeping records of the technology used by the Brotherhood. The attitude of many scribes in the Brotherhood can be described as techno-centric. While a great number study history and culture, the majority of scribes focus their studies on subjects related to the acquisition, repair, or creation of technology.


 * One example is Veronica Santangelo, a journeyman scribe of the Mojave Brotherhood of Steel, and a possible companion in Fallout: New Vegas.
 * Lorri's assistant is also described as a journeyman scribe in Fallout.

Scribe initiate
These are scribes in training. Serving in the East Coast Brotherhood.

Archivist
An archivist is a position introduced within the Maxson model. Little is known of their role inside the Brotherhood of Steel other than they can work with and directly report to the elder on matters assigned to them, and have a highly scientific skill set, capable of parsing energy readings and determining the source and possible purpose.

In 2287, the only known archivist was Archivist Knox who identified energy readings from the Commonwealth as originating from the Institute. Elder Maxson reviewed his findings and they both agreed on the possibility of weapon or other device development, and prompted his expedition into the Commonwealth.

Overview
The rank of Lancer is the dedicated pilot class of the Brotherhood. Lancers must undergo specialist training to learn how to operate and pilot Vertibirds and Airships. This training covers standard operating and piloting procedures but the real training is for piloting while under heavy fire. The primary role of a Lancer is to provide air support and carry out transport duties for ground forces. While Lancers are trained mainly for air combat, they also receive ground force training and often carry a laser weapon incase of being downed and caught in a firefight. The Lancer rank is entirely unique to Brotherhood of Steel under Arthur Maxson's leadership.

Lancer-captain
Lancer-captains are the highest ranking members of the lancers, being the head of the branch as a whole. Lancer-Captain Kells is the only named member of this rank.

Lancer-sergeant
Lancer-sergeants are the officers of the lancer branch.

Lancer-knight
Lancer-knights are veteran pilots and crewmembers of the Prydwen.

Lancer
Lancers are fully qualified pilots who have completed their training.

Lancer-initiate
Lancer-initiates are the lowest caste of the lancers. They are however still capable of piloting Vertibirds by themselves.

Operations officers
Not so much a rank, but a designated role for paladins tasked with coordinating assaults.
 * The only named operations officer is Operations Officer Edwards in Broken Steel.

Behind the scenes
"Elected or chosen by the elders, don't recall which, but I don't think specifics were mentioned anywhere so you can do whatever you want I'm sure without running into an inconsistency that the players might find."

- Dave Hendee on electing elders, Fallout Bible 8

"Knight before you can become a Paladin. Becoming a paladin is special."
