Abstract: A visual display and helmet assembly is configured to function in the presence of a harsh environment, e.g., high wind, vibration and shock and strong ambient light. The visual display preferably includes a transmissive liquid-crystal display to reduce the display's size and to enhance the intensity of a virtual image. In addition, the display is preferably reconfigurable so that different display indicia can be programmed as desired. To reduce probability of injury to a user, the visual display is carried on the exterior of the helmet with its center of mass positioned substantially on the midsagittal plane of the user. In addition, a mount permits the visual display to detach from the helmet when it is subjected to forces above a predetermined threshold. The mount is also permits yielding movement between the visual display and the helmet to enhance viewing of the image.
