Dayton, Ohio's Battle Sight Technologies has developed the MARC-IR, which is a pressure active chemoluminescent writing utensil that allows military special operators to write and mark walls in the infrared spectrum. The writing can be seen using night vision goggles in low-light and no-light environments.
Leveraging technology licensed from the Air Force Research Laboratory's Materials and Manufacturing Directorate, MARC-IR was demonstrated and tested with a variety of military special operators and first responders during Tech Warrior OPS events in April and July 2018. More
