Schofield Barracks, HAWAII – Soldiers from the 25th Infantry Division are testing innovative electromagnetic support systems to strengthen the Army’s ability to adapt and operate in the Pacific Theater. Partnering with industry experts through the Army’s X-Tech program, Tropic Lightning Soldiers are experimenting with emerging technology that promises to enhance battlefield awareness, reduce risks to troops, and advance multi-domain operations.

Staff Sgt. Clark J. Tequin, an electromagnetic warfare specialist assigned to the Multifunctional Reconnaissance Company, 2nd Brigade, 25th Infantry Division, emphasized the importance of this technology for future operations.

“The Army functions in multi-domain operations, and this is part of the cyberspace and electromagnetic spectrum,” Tequin said. “This allows us to fight in multiple domains throughout the battlefield. As we move forward in the Pacific, we need these types of technologies to help troops understand and have better situational awareness of the overall battlefield.”

This focus on adaptability demonstrates how the division is preparing for the challenges of modern warfare in a dynamic environment.

The tested system enables Soldiers to detect enemy activity without direct contact—giving commanders an edge in planning and protecting their forces.

“Systems like this allow us to create a baseline on the spectrum and understand what type of signatures might be out on the battlefield—what our enemies are using and how we can exploit those signatures,” Tequin explained. “For example, if our opponents use radios, we might be able to detect those specific radios and exploit their communication and other equipment.”

By developing the ability to see, sense and exploit adversary activity, the division strengthens its Lethality across multiple domains.

Working with industry partners is a key element of the division’s modernization efforts.

“It’s a good way forward as 25th Infantry Division continues to experiment with different technologies and really push the envelope on adapting to modern warfare,” Tequin said. “This is part of that multi-domain operation.”

This partnership reflects how we connect, communicate, and integrate partners as members of one team, showcasing how Soldiers and civilians can collaborate to develop solutions that directly enhance the warfighter.

That collaboration highlighted by Jessica Stillman, an X-Tech program manager, who explained the value of putting technology directly into Soldiers’ hands during first stages of development.

“It means that we are getting technology into the hands of the Soldiers early on and giving companies an opportunity to get feedback on the technology they’re developing,” Stillman said. “That way, they can iterate on it and ensure that it’s ready for field testing and ready for when it’s needed.”

Stillman noted that events like this bring both Soldiers and technical experts together, providing balanced insight.

“It brings together not only Soldiers, but also the technologists to really look at how the technology performs,” Stillman said. “It’s valuable to see what it looks like when the Soldier is using it in the field, and what it looks like from a technical or scientific perspective to ensure that the technology is actually going to work.”

Stillman’s comments reinforce the division’s value in partnerships —bridging industry and military expertise to accelerate innovation.

Sgt. Brock A. Gossling added that adaptability remains at the core of these efforts.

“Testing capabilities like this reflect that mindset because systems like these have to be adaptable and go after whatever the 25th Infantry Division has in front of them,” Gossling said. “We have to be able to use these systems and go after any targets in any area.”

Beyond adaptability, one of the fundamentals focuses on protecting Soldiers while accomplishing the mission. Gossling explained how electronic support systems enhance safety.

“Electronic support systems like these are important because they provide commanders with early warning and threat detection, so they have a better understanding of their awareness,” he said. “It also allows commanders to understand their income levels and limit the signature they output.”

This speaks directly to managing risk, ensuring that commanders can make informed decisions while minimizing risks to their troops, people, and mission.

Stillman emphasized that this is just the beginning of the Army’s partnership with X-Tech.

“This is the first experimentation that X-Tech is doing—not the last,” she said. “We have several more coming up, and Army senior leaders continue to ask how we can rapidly identify technology and get it into the hands of Soldiers. That is exactly what we will be doing in the months ahead.”

Tropic Lightning Soldiers are testing new electromagnetic support systems to sharpen Lightning Discipline and keep the division lethal and ready. By working with industry partners, leaders show Initiative and Agility to adapt faster than adversaries in the Pacific. And by connecting Soldiers with civilian experts, the division Strengthens Soldiers and Community, ensuring trust and readiness remain at the core.

Joint Base McGuire-Dix-Lakehurst, NJ — Soldiers with the 25th Infantry Division, 101st Airborne Division, 11th Airborne Division and Special Operations Command received first touch and training on the Army’s newest addition to its Electromagnetic Warfare toolkit, Spectrum Situational Awareness System (S2AS).

The three-week User Assessment consisted of a week’s worth of training on S2AS and the Electronic Warfare Planning and Management Tool-X.

“This developmental test simulates a brigade headquarters with two dislocated companies testing out the S2AS system,” Maj. Megan Bridges, Assistant Project Manager for S2AS said. “We want to ensure the system is able to sense, detect and report emitter information.

S2AS is an electromagnetic spectrum situational awareness system that provides commanders with real-time electromagnetic spectrum (EMS) Situational Awareness to support EMS related-decisions making.

“When we incorporate missions control measures on the battlefield to ensure that the enemy can’t see us, we need to minimize who can use specific frequencies, systems, and at what power levels and bandwidth are they using to make sure we’re minimizing the enemy’s ability to see our blue force signature, whether on an installation or on a battlefield,” Master Sgt. Mike Powell, 3rd Infantry Division explained.

Understanding, and ultimately controlling, the electromagnetic spectrum on the battlefield is crucial to the Army.

“The Army has been pressing very hard on what it means to own the EMS,” Col. Leslie Gorman, Army Capabilities Manger for Electromagnetic Warfare said. “You have to understand the EMS as maneuver space and, understanding what our emissions look like on the battlefield, what the adversaries looks like on the battlefield, the countermeasures that are need to be put in place.”

S2AS is specifically designed to provide that visibility and the visualization for Soldiers and for the commanders in order to make more informed decisions.

“The Army needs an organic electromagnetic warfare sensing capability, which the system provides,” Bridges said. “It also increases the Cyber Electromagnetic Activities cell planning bandwidth, another important function S2AS brings to the table.”

“S2AS, being the Army program of record for the spectrum manager, gives us the ability to define the electromagnetic operating environment,” Powell said. “With the system, spectrum managers can identify signals on the battlefield, on a FOB, or on an installation, detect and analyze the signals and then provide that information back to commanders.”

The S2AS capabilities were effectively demonstrated during this test event. As more feedback from Soldiers becomes available through future TIC 2.0 experimentation events, the Army can ensure continuous refinement of the system to enhance its capabilities.

S2AS is slated for fielding to TIC 2.0 units in FY26.

CAMP GRAYLING, Mich.—In modern warfare, battles are not only fought with rifles, tanks and artillery. Some of the most decisive victories are won across the electromagnetic spectrum.

At Northern Strike, the National Guard’s premier readiness exercise held this month at Michigan’s National All-Domain Warfighting Center, Soldiers trained in a high-intensity environment that pushed the limits of electromagnetic warfare, or EW. It tested their skills in realistic combat scenarios.

In classrooms, electromagnetic warfare specialists often train to disrupt, or “jam,” enemy communications, intercept signals and scan for threats. Jamming works by overpowering or confusing an enemy’s radio or data transmissions, preventing them from communicating or coordinating effectively.

Last year at Northern Strike, the 37th Infantry Brigade Combat Team, or IBCT, launched a pilot program that sent a mobile EW team into the field to disrupt the communication systems of units in training.

This year, the EW teams were embedded in infantry squads to create a more realistic, complex environment for Soldiers.

“This is a rare training opportunity in the National Guard and in the Army as a whole,” said Spc. Robert Bowley, an Electromagnetic Warfare specialist in the 37th IBCT from Columbus, Ohio. “To train with the equipment, you need the funding, and Northern Strike allows for that.”

Bowley was equipped with the Beast+ system, a handheld multi-channel receiver and transmitter designed for Army EW operations. The system scans the electromagnetic spectrum to detect enemy signals, identify spoofing or jamming threats and enhance battlefield awareness.

“The antenna gives you a general direction and signal strength. I can see anything on the [radio frequency] spectrum,” Bowley said. “We also have a power amplifier that lets us jam communication systems.”

Bowley, who also participated in the exercise in 2024, said he acted as “an early warning system. I will be giving the direction of the opposing force and jamming their comms.”

The mission brought together electromagnetic service members from the 37th IBCT, the Royal Irish Regiment and the Latvian National Armed Forces. The teams combined their expertise by embedding an electromagnetic specialist with the Irish regiment and managing signal towers with the Latvian forces to carry out a complex, coordinated operation.

“In my job, you are on the front lines. We are not cyber on computers, we are in the field,” Bowley said.

At 1800 hours, Browley and seven infantry soldiers from the 2nd Battalion, Royal Irish Regiment, British Army, stepped off to the Combined Arms Collective Training Facility, which simulates fighting in urban terrain. Once they arrived, the squad cleared the building and Bowley looked for the best place to set up the Beast+.

“Ideally, it would be on top of a roof,” he said. “But they have drone capabilities, so this [his location] was the next best thing. In the best case scenario you want to be high up and have nothing around you.”

While the Royal Irish Regiment placed obstacles around the building, Bowley found a dark corner with windows on both sides.

“We will be defending from up here. With this spot, I have a window on both sides and am able to get the antenna outside. The main thing that is important is what is being said over the radio. When I see something on my screen, I will know the direction they’re coming from,” Bowley said.

Bowley knew the long night ahead would test his focus. He monitored the electromagnetic spectrum for hours, watching for the slightest signal of an attack and standing ready to jam enemy communications.

“I brought a lot of caffeine,” he said, laughing. “We have the go-ahead to jam whatever. Usually, you have to really go through hoops. The problem with jamming is that it is risky. Turning off comms can do a lot. The things that I will be looking at jamming are important. Like when they call up nine-lines, or before an assault.”

Bowley’s squad was on defense, which required members to stay alert the entire time. At 2200 hours, they experienced probing from a platoon-sized element testing their defenses. A drone tagged four simulated casualties.

At 0300 hours, shouts echoed as infantry teams moved in to assault the objective. With their communications jammed, the attackers yelled to coordinate.

“They realized we were jamming them and immediately got off their comms,” Bowley said.

Moments later, the opposing force stormed into the room and took down the defending squad in the exercise.

Master Sgt. Jason Ross, the electromagnetic spectrum operations noncommissioned officer for the Army National Guard Information Advantage Division, said the exercise was a reminder of why electromagnetic warfare must be integrated into training.

“Communications systems have changed rapidly in recent years and now evolve almost monthly,” Ross said. “The threat has grown significantly. Thinking outside the box is critical, but it’s not always an easy discussion to have.”

This scenario was unique because the communications cell was on the red team, creating an unpredictable training environment.

“It is hard to duplicate what we are doing at Northern Strike. The approval for this type of training is tricky. The support that Michigan has given to this exercise is amazing,” Gilly said. “The reality is when we train on a rifle range, a Soldier knows what to expect. That is not the case with electromagnetic warfare.”

Maj. Tucker Palmatier, a cyber electromagnetic warfare officer and Cyber Electromagnetic Activities officer in charge of the 37th Infantry Brigade Combat Team, said training in electromagnetic warfare is challenging because of federal restrictions.

“The FCC [Federal Communications Commission] law on jamming dates back to 1934, which makes it difficult to realistically train for today’s technology-driven battlefield,” Palmatier said.“Our challenge is maximizing training opportunities without breaking laws or regulations so Soldiers know exactly what to expect when it matters most.”

Despite those hurdles, Palmatier said the operation was a success.

“Our enemy was not anticipating electromagnetic warfare. We were able to degrade their communications, which left them unable to coordinate their attack, allowing a smaller force to successfully defend the position,” he said.
