Lyons' Pride

The Lyons' Pride, led by Sentinel Sarah Lyons, is an elite unit of the Capital Wasteland Brotherhood of Steel.

The squad's members are equipped with rifles and heavy weapons and power armor. The Pride functions as the Brotherhood's mobile shock troops, reinforcing points against concerted or sustained Super Mutant attack, and spearheading raids into Super Mutant-held territory.

The Initiate Reddin gets in over her head while training, and is killed in front of the Lone Wanderer and Lyons' Pride by a Super Mutant Behemoth. Later, Sentinel Lyons makes the Lone Wanderer a honorary member before they trek to The Jefferson Memorial in a mission to restore the functions of Project Purity.

The Lyons' Pride badge differs slightly from the Brotherhood of Steel badge. Where the BoS badge has a winged sword with cog wheels around/behind the sword blade, the Lyons' Pride has a lion rampant imposed over the upper sword blade, inside the span of the wings, and no cog wheels.

The Lyons' Pride also has two special areas reserved for them within the Citadel's A Ring. Their meeting space, called the Great Hall, has a round bisected table that seats 15 (7 on the left, 8 on the right. Elder Lyons sometimes sits in the closest seat to the entrance on the right side, and Paladin Gunny sometimes sits at the table as well, suggesting the Great Hall (and perhaps the Pride) are meant to contain a max of 13 members.  The Great hall has two entrances, a main one and a secondary one through a pantry.  The main entrance is guarded by two Knights.  They are not members of the Pride.

The Den is where members of the Pride get some R&R. In addition to additional food stores, tables, and chairs, there are 4 cots in the back. Since the Pride has more than 4 members, and they don't seem to operate in shifts, it is likely that other bunk room, probably in A Ring, are also reserved for the Pride. B Ring holds the Barracks, which is likely where all non-Pride BoS soldiers sleep.

Appearances
The Lyons' Pride appears only in Fallout 3.

Broken Steel
The members of Lyons' Pride appear in the Broken Steel DLC expansion to the main quest, but only if they survive the assault on the Purifier in Take it Back. During Take it Back, all members of Lyons Pride except for Sarah Lyons and Knight Captain Gallows can die. The survivors will appear at Project Purity once Broken Steel begins, and will walk back to the Citadel where they spend the rest of the game. Each member of Lyons' Pride has a couple new lines of dialogue regarding the war with the Enclave.

The only exception is Paladin Vargas, who does not seem to appear in Broken Steel even if he survives Take it Back.
