A T-shirt used in Cambodia to try to deter kids from entering certain unsafe zones featured a boy squatting over a mine that he was poking with a stick. The silk-screened shirt was yanked from production, according to one account, when angered villagers kept asking why American personnel were distributing images of kids defecating over land mines. The squatting boy was eventually redrawn.
Alexander the Great ordered his metalworkers to craft giant helmets to fit men the size of 20-foot monsters. His soldiers would then leave the helmets strewn about in conquered villages, hoping to inflame the wildest imaginations of enemy armies passing through the area. Folklore has it that along the same lines, though pitching at a slightly lower angle, American psy-op specialists in Vietnam left foot-long condoms along the Ho Chi Minh Trail, presumably to preoccupy the enemy soldiers with hiding their wives and daughters.
