Autonomous drones are increasingly part of the security perimeter at U.S. military installations across the country, offering soldiers new ways to monitor threats, reduce personnel risk, and respond more quickly to potential breaches. 

Drone systems are shifting installation security from guard patrols and fixed cameras toward a layered, technology-driven approach to base defense. Officials and security experts say the drones are not replacing human forces, but rather augmenting them in early detection and reconnaissance.
