The term irregular, used in combinations such as irregular forces,
irregular activities, and counterirregular operations, is used in the
broad sense to refer to all types of nonconventional forces and operations. It includes guerrilla, partisan, insurgent, subversive, resistance,
terrorist, revolutionary, and similar personnel, organizations and
methods.

Friendly guerrilla units that have operated in the same area as
the hostile guerrilla units are usually willing to assist in the counterguerrilla effort. Such units may be effectively employed in extended
combat patrol harassing missions. In addition, members of friendly
guerrilla units can serve as trackers, guides, interpreters, translators,
and espionage agents, and can man observation posts and warning stations. When friendly guerrilla units are employed, they must be supported logistically and should be subordinate to the military force
commander who maintains control and communication by furnishing
a liaison party to remain with the friendly guerrilla force, and by controlling the support furnished. Special forces operational detachments are ideally suited for this purpose.
