Bandit (Broken Steel)

 are characters added to Fallout 3 in the DLC Broken Steel.

Led by Split Jack, they are plaguing the water caravans going from Rivet City to the Capital Wasteland. Leadership of the group goes to whoever "hits hardest" according to Jack - which is him currently.

Three of them will be attacking the bait caravan. While those are hostile, the others are initially friendly. Should you replace Split Jack by beating him in a duel, the bandits ask you to extort the "protection money" from Officer Lepelletier in his stead.
