Jackals

The Jackals are one of the three groups of raiders that originated from Vault 15, the other ones being the Khans and the Vipers. They most likely came out of the Vault in the 2100s.

They are your typical group of crazies. They have no morals except one: survival. They use group tactics to overmatch 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. They also fought extensively against the other two raider groups from Vault 15, until they were defeated by the Khans in 2135. After that, most of them fled east of California.

Timeline
In the near future: When Coleridge leaves, he points out that for about 24 hours after they leave, the Jackals will be distracted by the NCR train leaving.
 * 6 months before the PC arrived to Boulder: Galenski runs into a pack of Jackals, kills all but one, and heads home. The lone Jackal runs to his tribe and tells them about the truck, the man, and where he went. The Jackals stop fighting among their own tribes and move out in search of this new food source.
 * 4 months before: Galenski makes a run to Denver. On the way back he faces some Jackals but fails to kill any of them.
 * 3 months before: Jackals organize in strength in this region. Though they originally try attacking the dome, they quickly realize the truck is an easier target.
 * 1 month before: Larsen shoots one of his soldiers and offers the body to the Jackals. The NCR soldiers and the tribes became allies, both wanting to get into the dome.
 * 5 days before: Presper and his men arrive, shoot some Jackals,

Tribe features

 * They drop easily, or even run if wounded, but they're just waiting to claim the dead from either side. They don't do this for ghouls or super mutants because they don't taste good.
 * They hate ghouls because of the glowing ghouls.
 * They file their teeth to sharp points, and are proud of their long hair (cutting it is a shameful thing).
 * Their advantage is in numbers, not strength. Unarmed, melee, and (if they're lucky) guns. Most have knives and other cutting weapons.
 * They're often diseased.
 * Normally small family groups, they've banded together to eat Boulder. They even bring the women and children along for the hunt.
 * The leader, Banshee, is in a Mexican standoff with Larsen, as both want to get in and neither wants the other to live after that.
 * They became so savage and cannibalistic after a winter storm trapped them and forced them to eat each other, and now that's how they survive.
 * Generally they've been moving east because of pressure from the unified tribes. The Jackals know other tribes despise and fear them.

The Dome appearances

 * Boulder train station: Jackals are all over the place, trying to figure out what the train is and what it means. If the PC pulls up in their own train and the Jackals are present, they'll attack.
 * Truck Garage Entrance: This is what Galenski uses to get his truck in and out. Currently occupied by a bunch of Jackals (3 packs of 12). The Jackals have tried to block the engine with cars but the truck is big enough to bust through should it be going fast enough. A few junked cars are inside. Normally they'd use the radio, but it was broken in the last Jackal attack.
 * Quarantine Center Entrance: The Jackals have a scout nearby. A few more Jackals start showing up.

Appearances in games
The Jackals eventually did not appear in any of the games, but they were mentioned by Ian and Killian Darkwater in Fallout 1. According to a Duck and Cover interview with Sean K. Reynolds, the Jackals were to appear in Van Buren.
