Echo Posted March 21, 2003 Share Posted March 21, 2003 Whats the best settings for "normal" and "thermal" visability to simulate night action? Assume the weather is claer and the moon is full. 0 Quote Link to comment Share on other sites More sharing options...
Stoffel Posted March 23, 2003 Share Posted March 23, 2003 I would suggest about 200 meters with full moon. With rain or fog you should lower the normal vision range. Regarding the thermals,you can use any range you like. The latest generation thermal sights is very good. 0 Quote Link to comment Share on other sites More sharing options...
minmax Posted March 24, 2003 Share Posted March 24, 2003 On a night with a full moon / clear don't use thermal or night vision. Good troops would have red lens for light and in 30 minutes night vision using mark-2 eyeball is fine. Use flash bangs to screw up the bad guys vision. Keep in mind a warm fog on at night can reduce thermal's capabilities since it measures heat deferentials. It can be fooled just like reducing closure to fool a doppler radar. We would light drums on fire or dumpsters to simulate a heat source. Thermal thinks that a heated dumpster looks like an APC and drums look like individuals or a radio. Plenty of good ways to fake out thermal. And use of flash bangs / willie pete (White Phosphorous sp?) can blind thermal for enough time to shoot and skoot.

Coyote Posted March 26, 2003 Share Posted March 26, 2003 Night illumination is highly variable. Shadows are much deeper in moonlight and all color vision is lost as well. Even if you can see 400 meters in open terrain, like a road, your ability to spot targets in the brush is likely less than half of that at best. Passive night sights (Starlight Scopes) amplify natural light between 5000 and 35000 times depending on how new the technology is. In practical terms, individual weapon sights can extend a soldier's night vision to at least 400 meters in clear starlight and 800 in moonlight. Sight for heavy weapons at least double that. From my experience, the limit of the sight is as much the resolution as the illumination. Passive night vision technology is always slightly grainy and has less contrast than thermal imagers. Thermals present a synthetic picture to the user so the contrast is much higher. Unless you are trying to depict bad weather of some kind, thermals have the same ranges at night as in the day time.
