Raiders

Raiders are any group of wastelanders who pillage, plunder, murder, or otherwise ruin the day of anyone unfortunate enough to not be one of them. If there were still laws, they'd be outlaws. Raiders tend to organize into loose confederations of gangs in the post-apocalyptic wasteland and are a constant problem. Raiders typically prey upon travelers and very small towns, leaving more populous or larger areas alone.

2160s
Beside a great number of raider gangs encountered throughout the Core Region, there are three distinct raider groups referenced by the first Fallout: Jackals, Vipers, and Khans, although only the latter appear in the actual game. All three groups originated from Vault 15.
 * The Jackals: The first clan, the Jackals, is your typical group of crazies. They have no morals except one: survival. They use group tactics to over-match their enemies. They are craven cowards, though, and will not attack unless they know they can win. They band together in their hideaway and fight over the spoils.
 * The Vipers: The second clan, the Vipers, are mysterious followers of an ancient religion (or so they claim). They usually only come out at night to hunt for food or to conduct raids. They are very ruthless when it comes to combat. They prefer stealth to strength. They usually carry bone knives dipped in Pit Viper venom. This poison, when in the blood stream, paralyzes the victim. Most victims captured in this way are taken back to their hideout.
 * The Khans: The last group, the Khans, are probably the most dangerous. They live the lifestyles of Mongol warriors, raiding towns, burning what they cannot take and capturing the survivors for use as slaves. They usually travel in small scouting bands, but sometimes they roam as full war parties. The Khans above all else respect strength. They are eager in combat to prove their worthiness to the clan by engaging in hand to hand combat with fists or clubs. The Khans carry very few firearms. Anyone showing superior strength is worthy of their respect.

2240s
There are numerous different groups of raiders in Fallout 2, which are still a common sight in the wasteland, but only a few groups played quite a major role.
 * Bishop's Mercenaries: Operating out of a cave north of Broken Hills, protected by raised plates, falling traps and barbed wire-walls with locked and trapped doors. They were not true raiders, but mercenaries hired by the Bishop family of New Reno with arms supplied by the New California Republic. They merely posed as raiders to pressure Vault City to accept annexation by the NCR. They reside in the Mercenary Raiders cave.
 * The New Khans: Reappearing in the second game, they are led by the only survivor of the original group. They are hiding out inside the secretive corridors of the ruined Vault 15, protected by squatters.
 * Yakuza - Japanese-style raider gangs could be encountered during travels, armed with traditional swords.

Midwest
There are many raider gangs throughout the territory of Chicago. The majority of these raiders are well organized, because of a need to become one faction: the presence of Brotherhood of Steel, super mutants and Calculator's robots. They are cruel, sadistic people who are usually found near the eastern part of the region, far from super mutants and robots. There are several notable groups present.
 * The Main Faction: The faction was formed after four major raider leaders of the region (Luke Daniels, Bo Duffy, Daisy-May Gomer, and Jesse Gomer) forged an alliance to become stronger in order to fight their overpowering enemies. Their main base where the leaders hold their meetings is Rock Falls.
 * Gang of Devil's Graveyard: Powerful gang of raiders led by a man known as Gargantua. Their base is a place called Devil's Graveyard.
 * Gang of Macomb: A gang which was formed to assault strangers around Macomb, a town suffering because of famine. These raiders are looking for food and use roofs as cover.
 * Ghoul-haters: This group is actually an extremist party, dedicated to extermination of ghouls. They took over Springfield because the mayor claimed that ghouls are equal to normal, smoothskin people.

Texas
In Texas, only one known gang of raiders exists, but it is very large and powerful, being de facto rulers of the land. However, they have become but puppets to Attis, who use them to capture slaves for him. Their base is an old mill located in the town of Carbon, which is completely under their control aided by the Mayor who keeps them happy. The gang is unique because of its matriarchal rule, with female lieutenants and the main leader known as Jane, Raider Matron. The gang wears a yellow emblem on their clothes to differentiate themselves from outsiders. Aside from normal weapons, the Carbon Raiders are well known for using killer dogs and special flamethrower weaponry. They have the ability to brew alcohol on radioactive subsistences.

Capital Wasteland
The raiders of Capital Wasteland are mostly hostile, lawless, chem-addled ruffians who roam the wastes of the Washington, D.C. area. They have little in common with the raider clans of the West Coast, except for the Fiends of the Mojave Wasteland. They are encountered in smaller groups and are armed with a fairly wide range of weaponry. They can occasionally be found hunting with guard dogs as well. All raiders wear some form of raider armor (though not at raider brothels in places like Evergreen Mills) and have dirty skin. The raiders of the Capital Wasteland have no central leader, leaders being at the level of individual gangs. However, in The Pitt, Ashur has a whole bunch of raiders under his rule.

Raiders have no alliances with other factions and will attack everyone but other raiders or slavers. They appear to be quite cruel, as places they inhabit are usually filled with the mutilated bodies of other raiders and wastelanders, implying that they torture captured enemies and occasionally their own.

Mojave Wasteland
The Joshua Tree-speckled mountains provide a surprising amount of cover, especially the rock-strewn washes that run east-west just south of Nelson. This is the perfect location for packs of anarchic hunters, grifters, and psychotics to wait for an opportunity to steal, kidnap, or kill. These loosely-knit Raider gangs revel in chaos and anarchy. The Jackals are no more than a handful of scarred and tattooed reprobates, scraping out a living by preying on anything weaker than them. The (slightly) more organized Viper Gang consist of a slightly more skilled collection of ne’er-do-wells, dug in close to major roads to rob and plunder travellers and Merchant Caravans. Further north, are two much more pitiful gangs, who have lost their brethren (both in violence, or by recruitment) to the Fiends; the stinking Greaser Gang who terrorize the North Vegas Sewers, and the Scorpion Gang, who fight intermittent skirmishes with Westside residents. All these Raiders have no driving purpose or goal, other than to live to see tomorrow and raise as much hell as possible today.
