Manuel Pineiro and Chief Master Sgt. of the Air Force Kaleth O. Wright at the Global Reach Deployment Center Sept. 24, 2019, at Travis Air Force Base, California. As part of Air Mobility Command’s Phoenix Spark Tank, Staff Sgt. Timothy Miller and a team of innovators came up with an idea to modify the lights to increase the effective battery life to use while in austere environments. (U.S. Air Force photo by Tech. Sgt.
