Why is it called guerrilla?
Guerrilla warfare
In the Vietnam War, the Americans "defoliated countless trees in areas where the communist North Vietnamese troops hid supply lines and conducted guerrilla warfare",[29] (see Operation Ranch Hand). In the Soviet–Afghan War, the Soviets countered the U.S.–backed Mujahideen with a 'Scorched Earth' policy, driving over one third of the Afghan population into exile (over 5 million people), and carrying out widespread destruction of villages, granaries, crops, herds and irrigation systems, including the deadly and widespread mining of fields and pastures.[30][31]
