The US Army's 1st Cavalry Division conducted a live-fire exercise at Fort Hood, Texas, testing an autonomous system to protect armored formations from drones. The exercise, part of the Pegasus Charge initiative and Golden Shield concept, focused on integrating sensors, weapons, and command systems to create a layered defense network that can quickly detect, track, and engage aerial threats. This system aims to automate processes, reduce soldier workload, and provide continuous protection while utilizing an open, scalable architecture for rapid technology integration and improved response speed against modern battlefield threats.
The US Army has advanced its counter-drone capabilities with a live-fire exercise at Fort Hood, Texas, where the 1st Cavalry Division tested autonomous systems designed to protect armored formations from small unmanned aerial systems.
The exercise, conducted from April 7 to 9, marked a key phase in the division’s Pegasus Charge initiative and its Golden Shield concept.
The focus was on integrating sensors, weapons and command systems to build a layered defense network that can detect, track and engage aerial threats faster and with less burden on soldiers.
Exercise Golden Shield brought together kinetic and non-kinetic effectors, advanced sensors and command-and-control systems in a unified architecture.Developed with the US Army DEVCOM Ground Vehicle Systems Center and industry partners, the system is designed to protect maneuvering armored units from drone threats.
Officials said the goal is to shorten the sensor-to-shooter timeline by automating detection and engagement steps.The integrated approach also reduces cognitive load on soldiers operating in high-pressure battlefield environments while maintaining continuous protection against incoming drone threats across formations.
The system uses an open, scalable architecture that allows rapid integration of new technologies. It links sensors, weapons and vehicle protection kits across multiple tactical platforms, enabling a coordinated defensive network.
This design lets the system scale up or down depending on mission requirements.By connecting detection and engagement nodes, Golden Shield improves tracking and response speed, allowing armored formations to react quickly to low-cost, high-volume aerial threats that are increasingly common on modern battlefields.
A key milestone during the exercise was a fully autonomous engagement chain. In this demonstration, a sensor on one platform detected and classified a hostile drone, then transmitted targeting data to a separate weapon system on another platform.
The weapon system successfully destroyed the target, marking the first live demonstration of a cross-platform autonomous detect-to-engage sequence within the division’s test framework.
Autonomous kill chain tested“The future is formation-based layered protection, and this is the start of that,” said Alfred Grein, Executive Director for Research and Technology Integration for the US Army Capabilities Development Command Ground Vehicle Systems Center. He added, “Some are more mature than others. But understand that’s part of why we do experiments to determine what we think is ready to hand-off to Soldiers in the field environment.”
The exercise reflects a shift toward distributed air defense, where multiple platforms share sensing and engagement roles instead of relying on single systems. Officials said this approach allows faster adaptation to emerging drone threats while ensuring armored formations maintain mobility and protection in contested environments. It also supports ongoing Army modernization efforts focused on networked battlefield systems.
The Golden Shield concept also tested emerging interceptor technologies, including micro-missile systems designed for short-range counter-drone defense.These interceptors are aimed at Group 1 and Group 2 unmanned aerial systems and are launched from compact pods that can carry multiple missiles.
Each interceptor is designed to be cost-efficient, with developers reporting ranges of about 1,000 meters and precision guidance supported by radar and command inputs.
Cost-effective drone intercepts“The intent is to take these systems we tested this week and begin to integrate them within our armored formations’ training,” said Maj. Kevin Correa, 1st Cavalry Division’s Air and Missile Defense Chief.“In that way, we are able to fully exercise not only the systems, but the tanker’s ability to manage these systems while conducting their normal operations.”
Insights from the Golden Shield exercise will guide future Army decisions on integrating autonomous counter-drone systems into armored units.The results are expected to shape how the service expands layered defense concepts across formations under the Pegasus Charge and Transforming in Contact initiatives, strengthening survivability against evolving aerial threats.
