This source, "Psychological Operations in Guerrilla Warfare," functions as a training manual for guerrilla forces, specifically tailored for the "Christian and democratic crusade" of the Freedom Commandos in Nicaragua. Its central purpose is to outline methods for manipulating public perception and gaining popular support through both overt and covert psychological tactics, emphasizing that guerrilla warfare is fundamentally a political war where the "mind" of the populace is the primary target. The document details strategies ranging from "armed propaganda", where visible armed presence aims to inspire trust rather than fear, to the covert infiltration of "front organizations" and the orchestration of mass meetings through "agitators" and "shock troops." A significant portion of the text focuses on developing the "propagandist-combatant"—a guerrilla whose political awareness and persuasive communication skills are as crucial as their fighting ability, ensuring they can justify their actions and ideology directly to the people.
