The night sight can turn night into day for the soldier, which means that darkness no longer protects the adversary. The night sight allows to detect the movements of the enemy, exposing him to the precise shot.
Such an artifact looks like a telescopic sight: it makes it possible to see on any night that is not completely dark. A very sensitive photoelectric cell converts the image into an electrical signal, as it would in a television camera. Circuits like a high-fidelity amplifier amplify the signal. Then they turn it back into an image and project it onto a small television screen.
Even in the darkest night there is usually some light, if only from the stars. In such a situation, the soldier can aim precisely at a target 365 m away. For artillery, tanks, helicopters and airplanes, more powerful versions with a range of one kilometre are used.
If there is not even the slightest stellar light, a different instrument can be used, the infrared camera, which detects heat rather than light. Objects that generate heat - for example airplanes, missile nozzles or campfires - can be detected within a radius of several kilometres. These sights are routinely used in surveillance operations. Infrared cameras can also detect body heat.
When every soldier, tank and airplane is regularly equipped with night sights, combat will be possible 24 hours a day.
