it IS dark half of the time, ya know. Without nvd's, you aint hitting head on prone men at 50m, with any reliablility at all, except on pavement during the full moon. Under those circumstances, you might reach 100 yds. With such light, and a scope with an illuminated cross hair, you might hit fully exposed torsos at 200m, somewhat more than 1/2 of the time (ie, better than pure LUCK). NVD'S have to be FOCUSED, either on the target or the sights, or you ALSO have to have a lazer or infared sighting system (ie, ANOTHER battery dependent, electronic falling apart pos system on your rifle. ) When it's dark of the moon, especially in the woods, you will miss head on prone men a LOT at a mere 20m, and you will hit cover user's heads only by LUCK at such a range. In cold weather, batteries go dead in a very few hours of use, too. Slamming prone, when being shot at, gear taking bullet and frag hits, slapping prone in mud, water, snow, etc, scopes and electronic sights are going to get-obscured and WET. Wet electronics means corrosion, and you often have no way to dry them out, in the field. So much for all this bs "need" of long range. Your scoped match 308 isn't going to have a LICK more effective range than a 10" barreled 223 has, over half of the time.
