Norton is the leader of a mercenary group hired by "special interests" in the NCR as part of an effort to deal with the attacks on brahmin cattle caravans by super mutants from Black Mountain. Norton's group was given the mission to harass the mutants living in Jacobstown in order to get the mutants to either leave, or attack them to justify retaliatory action by the NCR military. If pressed, Norton acknowledges that Marcus's group is likely unrelated to the super mutants actually attacking the caravans, but states that he only cares about doing the job he was hired to do and getting paid.
If convinced to leave peacefully, Norton and his men will travel to a campsite on the highway west of Brooks Tumbleweed Ranch, where they will remain for the rest of the game. Unlike most non-player characters, Norton and his men do not fast-travel, and thus will not move unless the player is in the same active map cell as them.
Cazadores in the area may kill Norton and his mercenary group.
