"Conclusions on night driving devices for the T-34
The devices for driving tanks at night did not prove themselves.
- The field of view is weak.
- Only vertical objects are well defined. Terrain and horizontal objects are nearly invisible.
- Vision range is short.
A lot of improvement work needs to be done. The devices are not yet suitable for night driving, especially in nighttime attacks.
All materials regarding trials are with Lieutenant Colonel Dorofeev and Engineer-Colonel Afonin of the GABTU.
The devices themselves were destroyed during a breakout, which was documented.
