Psychological warfare. U.S. airmen load psychological warfare leaflets into bombs at a base somewhere in Britain. From the first days of the war, when British aircraft flew over Germany to drop loads of leaflets, psychological warfare has used this vital weapon, not only on the enemy but to inform civilians living in occupied countries of important events, to warn them of imminent danger or to direct their efforts in sabotage.
