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]
