Brotherhood of Steel (East Coast)

The Brotherhood of Steel on the East Coast, also known as the East Coast chapter or Eastern division, is an autonomous chapter of the Brotherhood of Steel, originally founded by in 2255 by the reformist Elder Owyn Lyons. Their headquarters is the Citadel, an imposing fortress built beneath the ruins of the Pentagon on the edge of what used to be Washington, D.C.. As of 2287, the Eastern division is under the command of Elder Arthur Maxson, the supreme commander of the East Coast Brotherhood of Steel and the last living descendant of the Maxson family line. As the Brotherhood's position in the West declines, the once-moribund Lyons' Brotherhood of Steel has been reformed into a major military force in under a decade, able to project their power and influence all along the Eastern Seaboard thanks to the drive and tenacity of its young elder.

During the late Lyons years, the chapter self-styled itself as the Lyons' Brotherhood of Steel. The name was dropped after reunification with the West.

Capital Wasteland
In 2254 the Brotherhood's ruling council, based in the Lost Hills bunker in Southern California, decided to send a contingent to the East Coast, with one primary objective: recover any and all advanced technology from East Coast cities and bases. The contingent was placed under the command of Paladin Owyn Lyons, accompanied by technological adviser Scribe Reginald Rothchild, who was privately Owyn's friend, as well as several veteran members of the Brotherhood, including Paladins Henry Casdin, Ishmael Ashur and Tristan.

On their way to the Capital Wasteland, the Brotherhood's expeditionary force came across the ruins of Pittsburgh, Pennsylvania. In a single night, the Brotherhood swept through the city from their staging area at Mount Wash, and eliminated any resident who put up a fight. The intent of the Scourge remains unclear, but many in the Brotherhood note that it was a marked change in the way the Brotherhood operates. Additionally, it is known that something was recovered from The Pitt during the Scourge, although to date it would seem that only Elder Lyons knows what it was. Fallout 3 Official Game Guide Game of the Year Edition p.43-44: "Pitt Raiders Pitt Slaves Trogs Wildmen Following the Great War, survivors established a settlement on the remains of a city at the confluence of rivers. The rivers seem to provide a clear resource, and enough of the city was cleared by the bombs that a new settlement could be established. However, radioactive material and unidentified mutagens mixed into the groundwater, causing it to become slightly mutagenic and highly carcinogenic. As a result, the people in the new settlement began to change ever so slightly. ''The changes were subtle, not nearly to the degree of the Super Mutants or the various Wasteland creatures, but over the next 140 years, it became undeniable that something was affecting the people of The Pitt. Starting from the first few years, children were often born with strange growths or extra vestigial limbs. The mutations never went far beyond the occasional hunchback or cleft palate, but it wasn't long before the vast majority of the residents of The Pitt developed some sort of physical deformity in their lifetimes. Although many children were born "clean," the older they got, the more likely that a problem would develop. The most disturbing change that the environment caused was not nearly as noticeable as the physical deformities. The infected water and poisoned sky began to cause neurological damage to those exposed to it. People became more hostile, violent, and short-tempered; they became known as "Wildmen." Their emotions became out of control, and their actions often teetered on primal. In severe cases, mutated humans devolved into hunched, savage beasts nicknamed "Trogs." Over the first 50 years, The Pitt quickly degenerated into a dangerous den of murderers and rapists; even cannibalism was not uncommon. The only loyalty was in strength, and the only organization was between those who were strong enough to control others and those who were controlled. Rumors of the horrors of The Pitt spread throughout the Wasteland, and all travelers knew to avoid it at all costs. However, The Pitt became one of the most self-sufficient communities in the Wastes. Granted, their self-sufficiency relied on the citizens occasionally eating one another, but they functioned without trade or export. In 2042 [sic], Star Paladin Lyons of the Brotherhood of Steel led the Scourge, a large-scale military action that wiped out nearly the entire population of The Pitt. In a single night, the Brotherhood swept through the city, eliminating any resident who put up a fight. Although the intent of the Scourge remains unclear, several unmutated children were taken from The Pitt by the Brotherhood and placed into initiate training. The motivations for the Scourge are unclear to this day, but many in the Brotherhood note that it was a marked change in the way the Brotherhood operates. Additionally, it is known that something was recovered from The Pitt during the Scourge, although to date it would seem that only Elder Lyons knows what it was. It is said that a Brotherhood of Steel Paladin from the Scourge stayed on in The Pitt, seeking to bring law and order to the unwashed masses and creating an underclass of Pitt Slaves in the process, guarded by Pitt Raiders under his personal command. However, in the decades following the events of the Scourge, nobody has heard anything from The Pitt. Travelers who have gone to investigate have not returned, and no survivors have emerged."'' (Fallout 3 Official Game Guide faction profiles) Lyons' contingent left the city with about twenty children in tow, who would later be initiated into the Brotherhood. Most were recruited into the Brotherhood. By 2277 only one remains stationed at the Citadel: Greg Bear, codename Kodiak, stationed with Lyons' Pride. Ashur himself survived and established firm control of The Pitt, transforming it into an industrial powerhouse, supported by Brotherhood technological know-how. At the same time, he abandoned the Brotherhood and its teachings, recognizing the inherent failure of the unsustainable, scavenger nature of the Brotherhood's ways.

On their arrival, the wilderness outside the city was overrun by super mutants. Attacking head-on, they drove the mutants into the ruins of Washington, D.C., and earned the favor of the local population. Their investigation of the Pentagon uncovered a remarkable cache of technology, including the four-story-tall robot known as Liberty Prime. The discovery earned Owyn Lyons a promotion to elder and a change in his orders: instead of returning to the West Coast, they would establish a permanent presence in the area. They founded their base, the Citadel, in the remnants of the old Pentagon.

The Brotherhood's treatment of people in Pittsburgh and in Washington marked a characteristic trait of Elder Lyons' leadership. The Brotherhood's primary directive was to recover and preserve advanced technology, however Elder Lyons' detachment took on a more humanitarian approach towards non-hostile wastelanders. When the Elders in Lost Hills learned of these new priorities, they cut off all support to the chapter, though they still considered it as part of the Brotherhood. The chapter suffered a further setback when a number from within their ranks left in protest to form the Brotherhood Outcasts.

It was in this weakened and isolated state that it was possible for the Enclave, having relocated from New California as well, to re-establish a base of continual operations at Raven Rock, to make its move. They seized Project Purity, then set up outposts in Washington, D.C., and the surrounding wilderness. However, with the assistance of the Lone Wanderer, the Brotherhood ended the Enclave's presence in the known region; driving them first from Project Purity and then from their final holdout at Adams Air Force Base. The fate of the Enclave as a whole after these events remains a mystery.

Despite the Brotherhood's success with Project Purity and the war against the Enclave, the organization continued to struggle. Lyons passed away in 2278, and leadership passed to his daughter Sarah Lyons. Not long after she was named elder, she was killed in combat with no clear successor in line. In the leadership crisis that followed, the Brotherhood repeatedly appointed and deposed one ineffectual leader after another until Arthur Maxson assumed leadership. In 2283, Arthur Maxson was appointed elder at age 16, the youngest in Brotherhood history, after displaying exceptional skill as a capable warrior and diplomat by defeating the super mutant leader Shepherd and brokering a peace with the Brotherhood Outcasts, bringing them back into the fold.

By 2287, the East Coast Brotherhood had established contact with Lost Hills and actively received support from the west. During this time, they made plans to establish control not only over the Capital Wasteland but the entire eastern seaboard. To complete this objective, they began the construction of a massive airship called the Prydwen, using parts from the Enclave mobile crawler at Adams Air Force Base. The development and construction process took a total of six years, two years to design the Prydwen and twice that to build.

The Commonwealth
During this time, the Brotherhood sent three scout missions into the Commonwealth: first, a group volunteered to go into the Commonwealth, then Recon Squad Artemis led by Paladin Brandis and Recon Squad Gladius led by Paladin Danse. The first scout team was overwhelmingly successful. They brought back crates full of pre-War technology and documents and the first post-War reconnaissance of the area. Artemis was not so fortunate with their problems beginning at their drop-off point in Malden. Ambushed by Gunners straight off the vertibird, which resulted in abandoning and manually shorting out their power armor (to prevent the suits from being captured) and the deaths of four knights. The survivors made their way to the National Guard training yard to regroup, which was infested with feral ghouls and resulted in the death of another knight. Brandis and his scribe left to investigate the pre-War Revere satellite array, but super mutants overcame them and claimed the second last member of the team. The only survivor was the commanding officer, Paladin Brandis, who made his way to a pre-War nuclear bunker and took shelter.

Three years later, Recon Squad Gladius entered the region also looking for technology and valuable documents. They encountered similar resistance from raiders as Artemis did and over the course of several weeks managed to secure a base of operations at the Cambridge Police Station but lost four knights in various confrontations. After discovering advanced signals originating from the Institute, Paladin Danse sent an emergency signal to the Brotherhood, which after several technical delays, responded by sending the Prydwen to the Commonwealth, dominating the skyline while under full vertibird escort. The Brotherhood established a permanent foothold at the Boston Airport and bolstered Gladius' position at the police station. At that point, the Brotherhood began to enforce their ideals upon the Commonwealth and investigate the mysterious energy readings.

Several members of the Brotherhood had their own projects to progress within while access to the Institute was researched. Proctor Quinlan required technical documents found in pre-War ruins that might have had information pertaining to important technology, weapon schematics, or military bunkers left behind in the war. Senior Scribe Neriah required blood samples from heavily irradiated species such as feral ghouls, yao guai, and super mutants. Even after Danse is banished from the Brotherhood, Recon Squad Gladius still needed to complete their duties in Cambridge Police Station, such as cataloging tech or cleansing an area of radiation infected beings.

In plotting a course to find, access, and destroy the Institute, Elder Maxson determined the first initiative to be repairing Liberty Prime back to working order, assisted by Dr. Madison Li. After securing ammunition from the sentinel site and a beryllium agitator, the operational robot clears the way for the Brotherhood to infiltrate and subsequently attempt to destroy the Institute once and for all.

Major outposts and locations
The East Coast Brotherhood is a major military power boasting vast supplies, manpower, cutting-edge technology, and scientific research in all fields, enabling them to hold power and influence all across the Eastern Seaboard. They hold many strongholds and bases throughout the wasteland, including the following:

GNR Radio studio
In 2277, when Owyn Lyons was elder, the Brotherhood had a large presence at Galaxy News Radio, a news radio station in the middle of Washington D.C. It was tactically and strategically important as it was a defensible location in the middle of the ruins of D.C., as well as having a mutual relationship with the DJ of the studio, Three Dog.

Washington Memorial
Also in 2277, a small Brotherhood unit composed of five soldiers was stationed here to defend the memorial, which had GNR's satellite on top of it. Unfortunately, because of the chaos in this area (with slavers in the Lincoln Memorial, Talon Company, super mutants and the Enclave in a three-way battle to seize the Capitol building, and super mutants having a foothold in the National Archives and the numerous bunkers ironically established by the Brotherhood after making a push towards the Lincoln Memorial), casualties were high and the satellite dish often got knocked off, which resulted in the troops there simply using the same dish over and over again. After one such incident, the dish was irreparable, which resulted in a wild goose chase for another one.

Pennsylvania Avenue
The Brotherhood has a minor rest and resupply area near the nuked remains of the White House, making their home in an abandoned hotel, where they rarely sleep, due to the constant super mutant advances upon this location.

Arlington Library
The Brotherhood has a major presence at the Arlington Library (officially the Library of Congress), where, in 2277, Elder Lyons has Scribe Yearling searching for intact pre-War books to add to their collection. They are also trying to wipe out the raiders who have fortified themselves in the library and who have become an annoyance to the soldiers trying to salvage the library for books or anything of use.

Project Purity
After the near-end of the war with the Enclave, the Brotherhood established a foothold in the scientific complex known as Project Purity, which was underneath the Jefferson Memorial. The Brotherhood employed Rivet City's Security Services to help them transport the water as well as protect the Project.

Adams Air Force Base
After the destruction of the Enclave's mobile base crawler, the Brotherhood set up a permanent base camp at Adams, attempting to gather what they could from the wreckage to construct the Prydwen. Arthur Maxson directed all resources to the construction of the Prydwen. After six years, the huge airship was constructed and served as a mobile command base for five years in the Capital Wasteland before setting off for the Commonwealth.

The Citadel
The Citadel is the bastion of the East Coast Brotherhood. Built amidst the ruins of the Pentagon, the courtyard was reserved for the training of initiates, who were trained by Paladin Gunny. From there, one could go to the Citadel laboratory, where scribes tediously multitask between their duties to their order (The Sword, Shield, or Quill) and a special assignment by Head Scribe Rothchild; more specifically, Liberty Prime. Paladin Bael is in charge of security outside of the Citadel, while Knight Captain Colvin (via Sarah Lyons) is in charge of security on the inside. Surrounding the central area containing Liberty Prime are A-Ring and B-Ring. In A-Ring The Brotherhood's council chambers are located (known as the Great Hall), where they either plan for future operations or direct field units. There are two small passageways connected to the Great Hall, used for storage, and both storing food and miscellaneous items. The northernmost room is known as the "Lyons Den," which serves as the rest and resupply reserved only for members of the Lyons Pride. The southernmost room is reserved for the Order of the Quill and all historical records pertaining to the East Coast Brotherhood, the Maxson bloodline, vaults in the Capital Wasteland, and the pre-War Pentagon.

Commonwealth
The East Coast Brotherhood holds numerous strongholds throughout the Commonwealth to serve as forwarding operating bases facilitating their operations against the Institute and other abominations in the Commonwealth.

The Prydwen
The main base of operations for the Brotherhood in the Commonwealth. The Prydwen serves as The Brotherhood's aerial aircraft carrier and contains all of the essential elements to make their operations possible; including barracks, research and development facilities, medical bay, munitions stockpile, and more. Proctor Teagan commands the Order of the Sword from the stowage on the Prydwen, and he's also in charge of the supply depot in the airport, where he has put Knight-Sergeant Gavil in his liege as CO. Proctor Ingram commands the Order of the Shield from the power armor bay, whose job is to keep the Prydwen afloat as well as repair any damaged gear or equipment soldiers bring in. She has also been charged with repairing Liberty Prime to working condition so the Brotherhood can use it to destroy the Institute. Proctor Quinlan commands the Order of the Quill from his quarters on the main deck. His duty is to organize field scribe escorts as well as research and file technical documentation brought back from the field by the Brotherhood's soldiers.

Apart from the three orders, Knight-Captain Cade resides in the medical bay, treating wounded soldiers and assessing new recruits in order to see if they're combat-ready. Cade is the one who refuses to clear Paladin Brandis for duty until the Sole Survivor completes either The Nuclear Option for the Brotherhood or completes the Mass Fusion quest for the Institute while working for the Railroad. Lancer-Captain Kells commands the Brotherhood's air force as well as controlling the flight path of the Prydwen from the command deck.

Boston Airport
Used as a place to moor the Prydwen, the Boston Airport serves many of the same functionalities as the Prydwen does. The Brotherhood uses the airport as a forward operating base for all of its operations in the Commonwealth. Supplies are stored here, as well as the remains of Liberty Prime, who the Brotherhood eventually rebuild to use against the Institute. The Brotherhood's best soldiers are stationed in front of where Prime is being built, where ranked soldiers up to star paladins can be encountered patrolling the walkway surrounding Prime. Behind Prime's building platform is the storage depot, where Knight-Sergeant Gavil stores all incoming rations appropriately, as well as supplying gear to field soldiers. Above that is a landing platform, where a general recreational area lies around it. Benches, vending machines, and several food items lay about to allow the Brotherhood to relax with each other before heading out.

Cambridge Police Station
Cambridge Police Station is the main operating base of Recon Squad Gladius, and serves as a "port in the storm" for the Brotherhood as well as another more central forward operating base to facilitate their missions. Before the arrival of the Prydwen, a six-man squad captured the station from feral ghouls (led by Paladin Danse), in order to function as their base of forward operations. As time passed, they lost two soldiers while on scouting patrol and another while under attack by feral ghouls. When the Prydwen arrived, however, the ghouls in Cambridge were merely a nuisance as synths began launching attacks on the police station. Now it functions as a rest and resupply before soldiers head back out into the chaos of the Commonwealth, with a Vertibird landing pad above and the rubble leading to it cleared. A power armor station lies beneath the station, with ample supplies to upgrade and repair any soldier's armor.

Society
The Brotherhood of Steel is a neo-knightly military order that rose from the ashes of the American military on the West Coast in the years following the devastation of 2077. The organization's tenets include the eradication of "abominations" such as super mutants and synths, as well as the veneration of technology. The Brotherhood has never been extremely keen on sharing their resources with their fellow wastelanders, considering them far too ignorant and irresponsible to possess advanced technology. Despite their obsession with technology, they will destroy technologies that they deem too dangerous or uncontrollable, like the Institute synths.

The eastern chapter of the Brotherhood is shown to generally be more benign than its western counterpart. They hunt down hostile mutants and robots, and keep dangerous technologies out of careless or malevolent hands. As with other chapters they prefer not to share their technology with outsiders due to the potential for misuse. Instead they use it themselves to help people in the wasteland in a safe and controlled manner. Despite this they are more lenient about outsiders possessing advanced technology such as energy weapons, and have been known to trade it on rare occasions for resources or manpower.

The Brotherhood's disdain for super mutants and synths stems from their belief that such "abominations" are the direct result of reckless scientific experimentation, i.e, "technology run amok." They hold the irresponsible use of technology by pre-War civilizations responsible for the planet's destruction, and actively seek to prevent a second apocalypse from occurring by maintaining a monopoly on advanced tech.

Recently, much like the chivalrous knights of old, the eastern chapter of the Brotherhood has been more interested in justice and safety for the obviously weaker and less fortunate around them to a certain extent. Ghouls and super mutants are not included, as the Brotherhood believes them to be dangerous. The Brotherhood has been far more assertive in the goings-on of wasteland politics and life. They continue in their mission of preserving and developing technology. The East Coast contingent of the Brotherhood when it was first founded had "gone native" under the leadership of Elder Owyn Lyons. Lyons felt the Brotherhood had a responsibility to protect the people of the Capital Wasteland from the super mutant threat; a notion not entirely lost on Elder Maxson, who continues to use soldiers to combat Super Mutants and other threats.

As of 2287, it is clear that the Brotherhood is an unrivaled power in the region, and draws most of its new recruits from the area. What started with the East Coast Brotherhood protecting people from super mutants and raiders led to defeating the Enclave and distributing free clean water to the people, turning them into the governing power in the Capital Wasteland. Based on information from dialogue, terminals, and holotapes the Brotherhood appears to have evolved politically and governs the Capital Wasteland directly as its own "country." Additionally, the Brotherhood now attempts to build, innovate, and improve technology, unlike their West Coast counterpart.

Relations with the outside
Originally under Elder Lyons' rule, the East Coast Brotherhood was known to trade with outsiders, but as of 2277, there were many incidents that made Brotherhood stop such activities. The Brotherhood was also known to help patrol and defend settlements such as Megaton until the super mutant threat escalated to the point that they were forced to withdraw from many key locations. In line with Elder Lyons' philosophy, Lyons' knights and paladins tried to protect any and all innocent wastelanders they encountered while out in the wasteland, and recruit them if possible.

Following the liberation of Project Purity, the Brotherhood cooperates with Rivet City security to distribute large quantities of purified water to various settlements across the Capital Wasteland. These settlements include: Megaton, Rivet City, Tenpenny Tower, Republic of Dave, Girdershade, Canterbury Commons, Temple of the Union, Arefu, Little Lamplight, Big Town and Oasis. They do not service any factions they (and most other people) consider to be evil: raiders, Paradise Falls slavers, Talon Company, super mutants, the Enclave and Brotherhood Outcasts.

By 2287, the East Coast division of the Brotherhood has compromised between the former Elder Lyons' altruistic vision and their traditional beliefs. They are relatively friendly towards human wastelanders and somewhat tolerate sentient ghouls, but have a generally hostile attitude towards super mutants, feral ghouls, and synths. The Brotherhood believes outsiders are too irresponsible and unrestrained to possess access to advanced technologies. They seek to control the dangerous technologies and would rather use them themselves to protect people rather than let the people themselves possess them. It is central to their beliefs that they must appropriate any dangerous technologies that they can control, and destroy the ones they cannot, such as the synths. By maintaining a monopoly on advanced technology, the Brotherhood hopes to protect the innocent and prevent a second apocalypse from occurring due to the irresponsible use of advanced technology.

Unlike the West Coast Brotherhood, the East Coast division under Maxson has continued Lyon's practice of recruiting outsiders into the Brotherhood. While Lyons hastily welcomed outsiders into the ranks to bolster their forces, the Brotherhood under Maxson is more cautious and recruits outsiders through a system of sponsorship. Under this system existing members of the Brotherhood can "sponsor" an outsider's entry into the ranks, making them an initiate. In this way, the Brotherhood is able to balance its need for new recruits with their desire to ensure the loyalty of new members.

Military
The East Coast Brotherhood's military structure is designed to create the most capable soldiers and pilots, while also educating them in technology to pick out potential scribes.
 * Squires are children who are too young to train as initiates but are allowed to serve the various needs of full-fledged members of the Brotherhood. In exchange, they are taught basic concepts such as military structure, combat readiness, and loyalty that will help them when they are old enough to become initiates. Squires sometimes accompany exemplary knights on missions, at the behest of Lancer Captain Kells, to experience combat firsthand but only as an observer.
 * Initiates are Brotherhood-born members and sponsored outsiders who are training to become knights, scribes, or lancers.
 * Aspirants is a rank used to denote someone training under a superior officer such as a paladin or knight-commander in order to be promoted to a full-fledged knight. They are a step above initiates
 * Lancers are the backbone of the Brotherhood's newly formed airforce. Without them, the Brotherhood would be unable to operate their fleets of vertibirds.
 * Knights are fully-fledged members who have served time in the Brotherhood. They are professional soldiers and the main backbone of the Brotherhood's ground forces.
 * Paladins are the Brotherhood's elite, seasoned veterans that are often high ranking field commanders or used in elite strike teams.
 * Scribes are the brains to the Brotherhood's brawn. They are responsible for the development and research of all brotherhood technology, as well as the maintenance of advanced systems, weapons and armor, and any other technical requirements.
 * Sentinel is a rare rank, only given to the Brotherhood's best and most distinguished soldiers. The last known sentinel was Sarah Lyons, daughter of Elder Owyn Lyons; she was the highest-ranking field commander under Elder Lyons and commanded the Lyons' Pride, a single squad of the chapter's best soldiers. The Sole Survivor can achieve this rank through the completion of A New Dawn.

Sometime after 2277, the Brotherhood formed an air force for the operation and training of pilots for their captured vertibirds. These pilots are known as lancers.

With all the Brotherhood's recent success, including the defeat of the Enclave and subsequent acquisition of all Enclave technology, including all power armor and weapons and the reintegration of the Brotherhood Outcasts, the East Coast division of the Brotherhood is at the zenith of its power. They have access to Vertibirds, power armor, and energy weapons. They also possess a new and improved, rebuilt Liberty Prime, as well as the Prydwen, a colossal airship developed by the Brotherhood, which Paladin Danse claims houses enough troops and resources to "push a full-scale offensive" and is capable of "mobilizing the whole division according to Arthur Maxson. Thanks to the Brotherhood maintaining their policy of open recruitment, their numbers on the east coast have vastly increased. Evidenced by the Brotherhood holding power and influence all across the eastern seaboard.

In light of their recently acquired fleet of Vertibirds, the Brotherhood division under Elder Maxson now frequently conducts operations within the Commonwealth, the foremost examples of which can be experienced in the missions Spoils of War and The Battle of Bunker Hill. Patrol and shock teams are frequently dropped into the Commonwealth to secure objectives deemed valuable to the Brotherhood or to eliminate hostile threats from an area.

Rank system
Exclusive to the current East Coast Brotherhood is a system of rank insignias among the knights and paladins. It has only been observed on their power armor so far but all the rank insignias appear to be based off a pentagon. The rank of initiate is an outline of a pentagon, then a full knight is a solid pentagon with chevrons added to it to denote knight-sergeants and knight-captains. A paladin's insignia is an elongated solid pentagon with a sword inside of it and a pair of wings flanking it. Sentinels and elders employ the same pentagon and wing motif but with a single diamond for sentinels and three diamonds for elders within the outline of a pentagon.

Special forces
Lyons' Pride, "The Pride," as it was colloquially known, was an elite unit of the east coast division of the Brotherhood of Steel under Elder Lyons. The Pride was led by the then-sentinel Sarah Lyons, daughter of the erstwhile Elder Owyn Lyons. Members of the Pride were hand-picked and represented the best that the Brotherhood had to offer. They wear the same T-45d power armor as the rest of the Brotherhood except for the Lyons' Pride insignia on the shoulder pauldron instead of the Brotherhood insignia. As of 2287, there is little to no information on the unit or its fate.

Technology
In 2277, the East Coast Brotherhood primarily used T-45d power armor; this armor was much more widely issued, being given to most front-line personnel, and not just select paladins. They still used energy weapons, mostly the laser rifle and the laser pistol. However, due to the difficulty of finding, producing new parts, and maintaining the laser-based weapons, and due to the fact that the Brotherhood no longer received supplies from the west coast, many paladins were forced to use traditional guns, notably the standard assault rifle and the Chinese assault rifle.

The Brotherhood has access to an extremely powerful pre-War superweapon, Liberty Prime, a nigh-invincible 40-foot tall anti-communist combat robot with enough firepower to decimate anything in its way. In 2277, it was destroyed by an Enclave orbital missile strike, although scribes in the Citadel had hopes of rebuilding him. After nearly ten years the Brotherhood transported his components to the Commonwealth and was able to not only rebuild Prime but improve on his original design, creating Liberty Prime Mk 2.

After the war against the Enclave, the Brotherhood gained access to a vast number of Vertibird gunships and stockpiles of energy weapons, power armor, and many other advanced armaments.

Thanks to years spent salvaging technology from across the wasteland and their victory against the Enclave produced vast amounts of pre-War power armor and aircraft for use in their operations throughout the wasteland. The combination of power armor and the fleet of Vertibirds the division operates gives it an edge against enemy factions. The fleet includes Vertibird transports and gunships. They are only armed with two forward-mounted 5mm and .30 cal machine guns and door guns (Rockwell CZ-57 5mm miniguns), along with. These aerial machines can transport troops and supplies across vast distances, provide attack, support and cover fire and give the Brotherhood air superiority. Second generation Vertibirds captured from the Enclave remain in service to the Brotherhood, though due to the limited numbers, none were fielded in the Commonwealth, rather using the first generation Vertibird design, retrofitted for Prydwen deployment. The design was in testing phases before the Great War, never reaching full production status except with the Enclave. The knowledge on how to manufacture more was either lost or otherwise destroyed by its remnants.

The crown jewel of the Eastern Division is the Prydwen, the first post-War airship launched in 2282 at Adams AFB. The vessel serves multiple roles for the Brotherhood, including those of aircraft carrier, command center, clinic, personnel quarters, equipment maintenance bay, and research facility. It allows the Brotherhood to project power along the Eastern Seaboard up to four hundred miles in any direction, thanks to the updated fusion plant pulled from the wreckage. One of its key advantages is the ability to store four vertibirds via skyhooks that allow for refueling, repair, and rearming in-flight. Due to the combustible nature of hydrogen that makes the airship float, the Prydwen does not participate in direct combat and travels under vertibird escort.

Appearances
The East Coast Brotherhood of Steel appears in Fallout 3, its add-on Broken Steel, Fallout 4 and its add-on Far Harbor. They are also mentioned in the other Fallout 3 add-ons, Operation: Anchorage, The Pitt and Mothership Zeta, and they are again mentioned in Fallout: New Vegas.

Behind the scenes
The East Coast Brotherhood of Steel has some similarities and differences with other Fallout games:
 * External recruitment is also present in Fallout Tactics, and for the "Texas Expedition" in Fallout: Brotherhood of Steel.
 * The Brotherhood Outcasts, renegades deserted from the newly established Eastern Brotherhood of Steel division, are similar to the Circle of Steel in Van Buren.
