The Enclave remnants are made up of people who used to serve with the Enclave on the west coast.
The Enclave did a lot of bad things, but there were good people at Navarro. Good people with a lot of experience. Not many of them are alive anymore, but I think they could make a difference in the fight against Caesar.”— Arcade Gannon
Squad members of the unit called the Devil's Brigade,  and as of Fallout: New Vegas, dubbing themselves the Enclave remnants, are a small faction of old Enclave veterans found in the Mojave Wasteland in 2281.
While the Enclave is stated as having relocated from New California to "a lot of different places" according to Arcade Gannon  some time after the events of Fallout 2, there were a few members that (apparently) decided to linger behind in Camp Navarro, rather than accompanying Autumn Senior and the rest of the Enclave in their journey to the eastern coast.
It is otherwise unknown why they decided to stay behind at Camp Navarro, as it is stated by both Judah Kreger and Arcade Gannon (respectively) that sometime after the Destruction of Control Station ENCLAVE, it was 'only a matter of time' for when the New California Republic and/or the Brotherhood of Steel would assault the Navarro outpost, for reasons also unclear.
The Devil's Brigade was disbanded sometime after the mysterious Sacking of Navarro at the hands of the New California Republic, and/or the death of Gannon Senior. During Fallout: New Vegas however, the player can convince the individual members of the Enclave remnants to reorganize and reunite for one final battle, another shot at glory, and a choice of either vindication (siding them with the NCR), or vengeance (siding them with Caesar's Legion)...
Interactions with the player characterEdit
The player has the option of completing the companion/side quest, For Auld Lang Syne given by Arcade Gannon, in which the player and Arcade attempt to make contact with his father's old squad-mates from the disappeared Enclave and help contribute to either an offense, or a defense during the Second Battle of Hoover Dam.
- Doctor Henry - Scientist/combat engineer 
- Orion Moreno - Soldier, heavy weapons trooper 
- Judah Kreger - Commanding officer (rank of captain) 
- Cannibal Johnson - Soldier, designated squad marksman 
- Daisy Whitman - Vertibird pilot 
- Through the choice of the Courier, the Remnants can be convinced to either support the New California Republic or Caesar's Legion.
- If the player chooses to ask them to side with the NCR, Orion Moreno leaves the room. He is found just outside the briefing room in the hangar. He will talk about his hatred of the NCR and will refuse to fight for them. If the player has a Speech skill of 80 or a large amount of NCR infamy, Orion can be convinced to participate in the attack, but otherwise he will attack the player and must be killed.
- If the player asks them to side with the Legion, Cannibal Johnson and Arcade Gannon will leave and there is no way to convince them to stay. The player can then talk to Orion Moreno for training in power armor. Moreno will give the player Johnson's suit since he won't be using it.
- Even though Arcade Gannon supports the idea of the Courier fighting for an independent New Vegas, there is no dialogue option to explicitly get the Enclave remnants to fight for New Vegas's independence, nor to assist Mr. House, who is similarly opposed to both the NCR and the Legion. In order to make an alliance between the Remnants and Yes Man or Mr. House, you must convince them to fight for NCR, since the path (battling eastwards through the Legion's ranks) and ultimate goal (killing Lanius) are still the same. However, Cannibal Johnson will turn hostile if the PC can not talk down General Oliver.
- Even if the remnants are killed during the Second Battle of Hoover Dam, the ending cutscene will still show them all as being alive.
- Although the remnants, by their own admission, ceased official service in the Enclave's Department of the Army decades before the time of Fallout: New Vegas, they still call themselves 'Enclave remnants'. This is despite the fact that they are not actually serving in the Enclave as active members anymore, for reasons uncertain, although it is implied to be nostalgia, because they state that they felt they had a purpose in the Enclave years ago, and that they miss it sometimes during the companion quest, For Auld Lang Syne.
