„First goggles were installed on GAZ-AA truck. It looked like a binocular with an electronic-optical light convertor. On top of the lorry they had a 250 watt infrared headlamp. Infrared sensors on the binoculars were converting the reflected light into a visible picture. It was powered by set of batteries inside the truck.
Driver could go as fast as 25 kmh (15 mph) in full darkness. His view was limited by 25 meter (82 ft) long distance.”
