Sefi,
If you are going to be in "no light" locations I would opt to take a thermal device. The way night vision units work is to take in elements of a field of view emiting light that is below the visible light scale for a human eye and modify that image so that it can be seen through the device. This is done in various ways depending on the type of device being used and the generation of the unit.
Starlight optics, specifically, take advantage of any available ambient light to assist in modifying the image it is being aimed at. So, cloudy nights, for example, the image will suffer.
Thermal devices are capable of "seeing" the heat that an object gives off. The heat is still on the light scale but lower than infrared light.

I've used both on multiple combat tours - the "Starlight" series is useful in more situations than thermal imagining.
The PVS5 series ( goggles ) and onwards have a built-in light source for areas with no ambient light but if your enemy has night vision equipmeent, you'll become a well lit target. Using the light souce ( it's IR ) drains the batteries at a fast rate.
The Soviet surplus NVG's are not worth risking your life with, so watch what you use.
