Rangers

In all Fallout games thus far, Rangers in general are paramilitary organizations that are independent and have a strict set of morals although they can still range from a sort of guardsman service to outright mercenaries.

Notable examples of Rangers include:
 * Desert Rangers (Fallout)
 * New California Rangers (Fallout 2, Fallout: New Vegas)
 * Reilly's Rangers (Fallout 3)
