On April 27, the Army hosted a tabletop exercise (TTX) with leaders from over a dozen top technology firms to accelerate the adoption of AI for cyber defense. The goal is to rapidly prototype and deploy new defensive capabilities to warfighters within 30 to 90 days. The scenario challenged participants to counter a rapid, AI-driven cyberattack, forcing them to identify scalable AI tools that can outmaneuver automated threats across the Army's complex networks. “We have to move faster to deliver the best capabilities to the warfighter,” said Secretary of the Army Dan Driscoll. “One of the hacks to do that is through better, more effective collaboration with industry…The Army that masters the integration of data, AI, compute, and human judgment into every warfighting function will have a decisive advantage.” The exercise yielded critical insights into the optimal balance between human defenders and autonomous machine responses.

To win the future fight, the Army must protect critical infrastructure “from the fort, to the port, to the fight, from the home station to the tactical edge.” This was the primary message delivered by Lt. Gen. Jeth Rey, Army Deputy Chief of Staff, G-6, during his keynote address at AFCEA Belvoir’s Industry Day on May 6. By modernizing architecture through Next Generation Command and Control (NGC2) and C2 NOW, the force is prioritizing resilient, mobile systems that function in contested environments, emphasizing synchronization over mere convenience. “To ensure commanders have trusted data at speed, we've stood up the Army Data Operations Center (ADOC)—our 9-1-1 for data,” Rey explained. He noted that the Army is enforcing a Modular Open System Architecture (MOSA) to help ensure data integrity at speed. This shift is designed to protect the force and the network at the tactical edge of the fight against adversaries attempting to disrupt communications. “The enemy is trying to separate us from our data and from each other,” said Rey. “So, we’re changing the architecture. Through NGC2 and C2 NOW, we’re moving fast: lighter formations, mobile systems, data and compute at every echelon.” Rey concluded with a blunt assessment of the mission’s scope. “The hard truth is that if we cannot secure the path from fort, to port, to the fight, our ability to project power effectively is challenged from the outset.”

The U.S. military's cybersecurity relies on the strength of its allies, making joint training essential. This principle was one focus of Exercise African Lion 2026 (AL26), U.S. Africa Command’s premier annual event, which brought together 550 service members in Tunisia to strengthen regional cyber defense. The curriculum focused on incident response simulations and forensic analysis to bolster collective security. The objective was to elevate the cyber readiness of international partners to build capacity, counter competitor influence, and secure military networks. “This cyber training means a great deal," said U.S. Army Maj. Joseph Augustin of the U.S. Army Reserve Cyber Protection Brigade. "It means we are broadening our partnership and learning from each other now so when there is a real war in the cyber domain, we have some familiarity with one another.” #cybersecurity #armycyber

Future conflicts will deal with an electromagnetic spectrum that is chaotic and saturated. To win, the United States military must generate, move, and project combat power faster than adversaries by ensuring data, integrated systems, and resilient infrastructure are reliably accessible from a unit’s home station to the tactical edge: “from the fort, to the port, to the fight”. That was the message of the Army Deputy Chief of Staff, G-6, Lt. Gen. Jeth Rey, during his keynote address at AFCEA Belvoir’s Industry Day on May 6 in Alexandria, Virginia. “The fort is no longer a sanctuary,” Rey stated. “It’s a contested space…. Our installations are deeply tied to commercial power grids, water systems, local communities, and industry partners. So, defending the fort isn’t just about what’s inside the gate. It’s about the ecosystem.” With this in mind, Rey said, “We’re building resilient installations through partnerships with utilities and communities, not as a backup plan, but as part of the design.” Moving from the fort to the port, Rey said, “At the port, we must trust our data, our manifest, and that what we load is what we'll receive in the fight. If the data is wrong, the plan is wrong, and momentum is lost. The port is the strategic support area that is built on trust…. The adversary doesn’t need to destroy a tank. They just need to make sure it shows up without ammunition. This is where momentum is built or lost. Adversaries just need to create friction…. So, our focus is simple at the port: Trust the data. Move without friction. Stay synchronized.” #datacentricity #armymodernization #cybersecurity

Attention U.S. Army Personnel: Important Mobile Connectivity Update. The U.S. Army is modernizing its mobile communications and officially transitioning from the Defense Mobility Unclassified Capability (DMUC) program to the new Army Mobility Program (AMP). Deadline: May 30, 2026. After this date, DISA will cease support for all Army DMUC devices. What you need to do: 1️. Disenroll your government-furnished equipment (GFE) mobile devices. 2. Turn them in to your local Telephone Control Officer (TCO) before May 30. (Exceptions require General Officer/SES approval). What's next? The primary method for staying connected is the Bring Your Own Device (BYOD) program. Using secure applications like Hypori and Mobile Application Management (MAM), you can access an encrypted workspace on your personal device without carrying a second phone. The Army’s monitoring is strictly limited to these secure apps, keeping your personal data completely private! As Lt. Gen. Jeth Rey, Army Deputy Chief of Staff, G-6, noted: "The Army Mobility Program gives our people a more flexible, secure and user-friendly way to stay connected to the mission..."

In his 2025 Cyber Defense Review article, “The Battlefield is Not ‘Over There’ – It is Here, 24/7,” Army Deputy Chief of Staff, G-6, Lt. Gen. Jeth Rey issued a stark warning: we must proactively protect our homeland's critical infrastructure from cyber-attacks. Recently, the Utah National Guard conducted Exercise Wolverine, a large-scale homeland defense training event directly addressing this threat. The large-scale homeland defense exercise centered on a simulated cyberattack targeting a vital water treatment plant. Military cyber specialists deployed via Black Hawk helicopters to work alongside civilian operators and restore essential services under realistic, time-sensitive conditions. “The fight in cyberspace is right here in our local communities...it’s when we turn on the lights, and every time we take a fresh drink of water,” said Utah Army National Guard Capt. Tyler Jacox. “Those critical services make up the modern battlefield, and the Utah National Guard is able to get ahead of this threat and maintain these services that Utahns depend on.” This joint training strengthened interagency coordination and ensured state resilience against complex threats.
