Irregular forces: All the irregulars are made up of locals. They are usually not as well armed as the regulars, but they are free so who's complaining. They meld back into society when they achieve their goal (rebellion, invasion stoped, etc).

What sets off rebellion? Rebellions may get started by events and whatnot, but most rebellions happen when unrest gets out of hand. This can occur in all sorts of different ways: government policies that run contrary to a population's race/species/ethos preferences, high unemployment, governmental incompetence, etc.
