"...Here volunteers are trained and indoctrinated, and from here, agitators and propagandists set forth, individually or in groups of two or three, to "persuade" and "convince" the inhabitants of the surrounding countryside and to enlist their support.

The pattern of the process is conspiratorial, clandestine, methodical, and progressive." --Mao Tse-Tung on Guerrilla Warfare
