Abstract
The arrangement for firing simulation and battle simulation, for reflecting mages generated by means of a computer (12) into the beam path (15) of a sighting device which has a cathode-ray tube (5, 6) for producing the images, is designed in such a way that it can be used even in widely varying external brightness. For this purpose, the cathode-ray tube (5, 6) emits essentially monochromatic light, while a narrow-band absorption filter (16) for the wavelength of the cathode-ray tube (5, 6) is located in the beam path (15) of the sight outside the beam path of the generated images.
