# Đừng cho ai biết việc mình làm (Let no one know what you are doing) (Vietnamese poster distributed in Vietnam)

A Vietnamese-language poster in orange, grey and black. Three uniformed men, two in berets, talk over drinks at a table while a woman in a long dress watches from behind a curtain. The slogan tells soldiers not to let anyone know what they are doing. The tell is fear-appeal: an eavesdropper at the curtain is the visual threat attached to careless talk about military matters.
