The US' New Smoke Grenade Will Obscure IR Detection

The US' New Smoke Grenade Will Obscure IR Detection March 20, 2018

The US Army is working on developing a new kind of smoke that obscures both visible and IR detection.

In parallel of the advancement of sensors beyond the visible region, the new smoke grenades will provide invisibility to the soldiers in both visual and IR spectrums and will contain fewer amounts of toxic material compared to conventional smoke grenades. Zach Zander, a researcher at the US Army's Edgewood Chemical Biological Center said the traditional army smoke grenade is made with a toxic material, called hexachloroethane, but terephthalic acid grenades were emerging as a safer alternative.
