Generation 3+ NVGs are pretty good the gen 4 ones are super expensive. You can see pretty much anything at like 200meters. You can look thru tinted cars and see the skin tone and sex of people driving at night. You can see dozens of shooting stars in the sky.

Honestly NVGs are great if you aren't facing another military. The thermal optics most modern-day countries use are far better, but they are not always very mobile.
