I can speak about Soviet night vision equipment.

Development of night vision devices began in the late 1920s, but there was no prototype produced before 1940. The initial goal was to create night vision driver's observation devices so that tanks could drive at night, rather than fight. Trials in the winter of 1940 showed that the concept had some promise and development continued. Requirements composed in March of 1941 had a second scope for the commander. The goal was still the same, to drive at night with a speed of 10-20 kph (due to realistic expectations of the range of the vision), but there was also a provision for an IR signal lamp for nighttime light signals. However, by May 29th there was already talk of an IR scope for the gunner as well with a range of 200 meters.

The experiments for a driver's device were still the most promising. By August of 1942 a satisfactory device was developed that allowed the driver to see large objects from 50 meters, vertical items such as a person or a pole from 35 meters and road features from 12 meters. Clarity in complete darkness was similar to observing with the naked eye in moonlight. An experimental batch of 25 devices was produced and sent to the 26th Tank Corps for field trials. Trials showed that it's possible to drive at a speed of 12-15 kph with hatches closed when using the devices, and a human figure can be seen from 30 meters away in motion or 50 meters away when stationary. There were specific complaints made about several features of the devices, even though the concept was deemed promising. The chief of the GABTU ordered 60 more improved devices in order to conduct wider trials.

The 26th Tank Corps used the devices in battle until the spring of 1943, when they had to be destroyed during a breakout from encirclement. They were still judged to be far from perfect, especially in use during nighttime attacks. No significant improvement was made to Soviet tank-borne night vision devices during WWII and as far as I'm aware they were never used in battle again.
