Brotherhood of Steel (Fallout: New Vegas)

The Mojave chapter is a contingent of the Brotherhood of Steel active in the Mojave Wasteland.

Background
While officially sent out to secure Hoover Dam, the formation of the Mojave chapter was due to disagreements within the elder council. Elijah, a scribe-come-elder, pushed for the development of new technologies, which put him at odds with the more conservative members of the Brotherhood. As Elijah proposed developing new ethically questionable weapons, the elders decided to send him away to the east, to form a new chapter of the Brotherhood in the Mojave.

The new chapter settled into the Hidden Valley bunkers, then discovered HELIOS One. Elijah, already considered unorthodox for his focus on improving technology rather than preserving it, had ordered for it to be converted into the Brotherhood's headquarters despite objections from the chapter's paladins. Elijah's obsession with HELIOS One and the need to defend against NCR forces deploying into the Mojave resulted in the Brotherhood ignoring the expansion of the Van Graff family into the Mojave, despite them distributing pre-War energy weapons.

Operation Sunburst
In 2274, the NCR moved into the region, seeking resources such as the electricity of the Hoover Dam. The faction subsequently set its sights on the HELIOS One solar plant. Elijah believed that the plant contained an unprecedented military advantage and when the NCR attacked, he refused to retreat.

Despite their superior equipment, the Brotherhood lacked reinforcements and were gradually worn down by NCR's numbers. By the time a retreat was ordered, more than half the chapter's paladins and knights had died. Elder Elijah disappeared and Brotherhood survivors retreated to Hidden Valley.

Hidden Valley
Due to his actions during the conflict, Head Paladin McNamara became the elder of the chapter. He locked down the bunker in order to regroup. All operations take place at night, and the engagement of NCR forces is strictly forbidden. No outsiders are allowed inside the bunker without a sponsor and the only people cleared for surface access are patrols, scouts, and procurement specialists.

Since HELIOS, the Brotherhood has half the number of troops but the NCR has increased their numbers five times over. All members of the chapter are direct descendants of the original Brotherhood, as the chapter does not accept new members. This contributes to internal conflict, as members want to resume activities on the surface as well as supplement their numbers before the faction ceases to exist.

Currently, members of the Mojave Wasteland chapter utilize mismatched power armor, comprised of both T-45d and T-51b models. Their weapons consist of tri-beam laser rifles, Gauss rifles, Gatling lasers, laser RCWs, and zap gloves. Scouts bring back weaponry that is stored in the Brotherhood armory.
