Raiders

The Raiders surface as a new enemy post-nuclear holocaust, as an independent party with no remorse for anything but themselves. They live and operate outside the Rocky Mountains in many areas and ruined towns collecting provisions for their own, and to continue their terrorization of communities and the U.S. government rebuilding inside and out of the Rocky Mountains region.

A lthough not very intelligent, they still threaten to undermine and sabotage U.S. assets operating in the Rocky  Mountain region.
