The Jackals are one of the three raider tribes that originated from the inhabitants of Vault 15 (the others being the Vipers and the Khans). The Jackals are a very weak group of raiders in Fallout: New Vegas, having been reduced to a shadow of their former strength by the lawbringing forces of the NCR.
Most Jackal gang members are generally poorly equipped, with the majority of them being limited to low-level melee weapons such as knives or lead pipes. One or two Jackals in a group of 4-6 may carry a 10mm pistol or a varmint rifle, and a Jackal may extremely rarely be equipped with a cowboy repeater. Their armor is likewise very poor, with most wearing either wasteland outfits, merc outfits, or (slightly less commonly) leather armor. Occasionally, a Jackal gang member may be equipped with metal armor. A low-level character can usually take them down with minimal hit-point loss, although a Jackal with metal armor can resist weak firearms (with a DT as high as 12, although any AP ammunition will negate the entire resistance) and pose a moderate threat.
Most groups of Jackal gang members are lead by a Jackal gang leader, who has slightly superior health and combat skills.
