Preston Dunlap, Air Force chief architect, briefs Department of Defense senior leaders during the first ever Advanced Battle Management System live demonstration at Eglin Air Force Base, Fla., Dec. 18, 2019. During the first demonstration of the ABMS, operators across the Air Force, Army, Navy and industry tested multiple real-time data sharing tools and technology in a homeland defense-based scenario enacted by U.S. Northern Command and enabled by Air Force senior leaders. The collection of networked systems and immediately available information is critical to enabling joint service operations across all domains. (U.S. Air Force photo by Tech. Sgt. Joshua J. Garcia)
