Sorry for necro but I think I found a counter for thermal image. TL;DR Smoke can block thermal image I found myself a SVD Camo and I wanted to familiarize myself to scope, so I loaded up the Shooting range 1.1 to test it. And while I was there messing with the guns, I decided to test my idea of using smoke to block thermal imaging. What I found out was that if there is enough smoke between target and gun, smoke will block the thermal image. Bad news is, you need at least four smokes to almost completely fade from the view. To test this I set my target soldier moving in 500 meters and used a M32 loaded with white smoke. I aimed to my feet to prevent grenade to bounce off somewhere, and made a line of smokes couple of meters apart. Then looked trough it with L85A2 AWS and AS50 TSW. Target soldier was barely visible through the smoke. Too bad there was no road flares, so I couldn't test those. And I'm sorry for lack of video, but my system can barely handle ArmA 2, so I can't capture anything. Now the next question is, does this information have any real use? No, not really. It's just a proof of concept for a questions that I had from this thread. You don't normally go around with 4-5 smoke grenades just to escape from L85A2 AWS, and just 1 is enough to hide you from his buddy with an AS50. And enough to generate "white noise" from all the zombies happily kicking the smoke grenade. But maybe someday smoke particles are thick enough to work in lesser quantities. Not to mention that normally smoke grenades tend to burn a bit hot while working.
