4ID successfully tests new technology to triage and evacuate Soldiers in simulated LSCO environment

Fort Carson, Colo. – The 4th Infantry Division tested advanced wearable sensors and end-user software during Ivy Sting 4, demonstrating how real-time physiological and environmental data can improve casualty triage, treatment, and tracking during simulated combat trauma, Jan. 26 to Feb. 5, 2026.

The technology supported sensor-assisted triage, treatment, and tracking (SAT3) across multiple brigades under realistic large-scale combat operations (LSCO) conditions.

Led by the Division Surgeon Cell (DIVSURG), the effort integrated the technology into Next Generation Command and Control (NGC2), enabling commanders to visualize casualty status, risk, and evacuation timelines across the battlefield.

2nd Lt. Victoria Hyten, platoon leader, Charlie Company, 64th Brigade Support Battalion, 3rd Armor Brigade Combat Team, 4ID said that by integrating medical technology from the time an injury occurs enables a continuous flow of real-time patient information: line medics are able to constantly see vital signs, digital documentation reduces time spent on manual charting, wearable sensors and patient tracking systems allow receiving facilities to monitor enroute vital signs, anticipate patient arrival and prepare resources in advance, and for evacuation units, this improves communication, response times, and coordination with treatment facilities, ultimately increasing survivability and sustaining combat power.

“Real-time medical data provides medical commanders with an accurate common operating picture of patient flow, bed availability, and evacuation asset status. This visibility allows for faster decisions, better resource allocation, and proactive repositioning of medical assets,” said Hyten. “By reducing information delays and improving accuracy, the technology strengthens command and control and ensures responsive medical support to operations.”

DIVSURG partnered with the Capability Program Executive – Chemical, Biological, Radiological, and Nuclear Defense (CPE-CBRND), which provided lightweight, body-worn sensors capable of monitoring vital signs, physical exertion, and environmental conditions in real time, including indicators of CBRN exposure.

Soldiers wore the sensors and employed the end-user software on Android Tactical Assault Kit devices during casualty simulation scenarios ranging from burn and blast injuries to CBRN contaminated patients.

SAT3 data integration enabled frontline medics, commanders, and medical teams to link wearable sensor data with digital 9-line medical evacuation (MEDEVAC) requests, improving evacuation speed, casualty status visualization, and performance under realistic training conditions—without disrupting mission flow.

Staff Sgt. Walter Michener, medical platoon sergeant, Headquarters and Headquarters Troop, 4th Squadron, 10th Cavalry Regiment, 3ABCT, 4ID said that faster 9-Line requests have multiple operational benefits including returning combat strength as soon as possible to combatant commanders, optimizing asset allocation for higher echelons, and increased Soldier confidence in Army medicine.

“Soldiers getting to an operating table within an hour can drastically increase their outcome; with 9-lines being more efficient with technology, brigade and higher assets can manage evacuation platforms better and prevent over-allocation,” said Michener. “Overall, the more efficient that 9-lines and MEDEVAC can be, the more trust will be put into us, knowing that help is always on the way.”

Testing demonstrated that the sensors delivered accurate, actionable, and secure data while remaining comfortable and durable in austere field environments.

Commanders were able to monitor patient status, location, identification, and environmental conditions across multiple brigade areas of operation, enabling faster and more informed decisions. Medics reported that access to real-time data improved their ability to triage and treat casualties and enhanced early detection of potential injuries or health issues, reducing the risk of serious medical incidents during high-intensity training.

“The results are significant steps toward data-driven patient regulation, sustainment and protection visualization, and overall unit readiness,” said Col. Paul Smith, Director, Transformation and Lessons Learned, Division Sustainment Brigade for CASCOM. “The near simultaneous sharing of data across multiple echelons of the battlefield enables commanders across the division to make data-informed decisions at a speed once thought impossible.”

By integrating wearable sensors and rapid digital 9-line MEDEVAC into operational training, 4ID demonstrated how emerging technologies enhance tactical combat casualty care, improve survivability, reduce disease and non-battle injuries, and modernize how the Army prepares to fight and win in future conflicts.
