Guerrilla warfare is defined as fighting by groups of irregular troops (guerrillas) within areas occupied by the enemy. When guerrillas obey the laws and customs of war, they are entitled, if captured, to be treated as ordinary prisoners of war; however, they are often treated by their captors as unlawful combatants and executed. The tactics of guerrilla warfare stress deception and ambush, as opposed to mass confrontation, and succeed best in an irregular, rugged, terrain and with a sympathetic populace, whom guerrillas often seek to win over or dominate by propaganda, reform, and terrorism. Guerrilla warfare has played a significant role in modern history, especially when waged by Communist liberation movements in Southeast Asia (most notably in the Vietnam War) and elsewhere.
