In support of Operation Lethal Eagle, the U.S. Army Communications-Electronics Command Army Software & Innovation Center delivered advanced operational capabilities, actively strengthening visibility of Class VIII Medical Logistics equipment. This initiative employs data from the Battlefield Assisted Trauma Distributed Observation Kit-Joint, a handheld digital device Army medics use to document injuries and treatments, ensuring leadership maintains situational awareness and makes informed decisions.
Operation Lethal Eagle is the 101st Airborne Division’s training exercise focused on air assault operations, large-scale combat operations, division-level synchronization, and real-world mission command. The implementation of BATDOK-J during the operation underscores a focus on continually testing and improving medical documentation on the battlefield. The exercise was held January 18 to February 7, 2026, at Fort Campbell, Kentucky.
CECOM ASIC refined complex medical logistics data and transformed it into unit-specific, near-real-time visibility of medical injuries, causes, vital signs, treatments, locations, and times. The new capabilities were integrated into Palantir Maven (a data integration and analytics platform) through collaboration with Medical Future Concepts Development at the Transformation and Training Command and the Office of the Surgeon General, Headquarters, Department of the Army.
Actionable insight
Why is structured data so critical during large-scale exercises?
Having operationally aligned data enables the Army to see itself through data. This improves operational decision-making readiness.
“Medical data is operational data,” Lieutenant Colonel Daniel D. Heffner, Chief Technology Officer to the Army Surgeon General said. “The Army Surgeon General’s vision of 'Combat Ready Care' does not stop at the casualty’s bedside—it means evolving all our medical functions through innovative technology to meet the demands of the operating environment and maintain the trust of our warfighters.”
Viewing this data during Operation Lethal Eagle lets leaders and medical teams understand which actions are performed over time and their effects, enabling informed decision-making and increased readiness.
“This is groundbreaking work in the realm of tactical operational medicine battle tracking,” Deputy Consultant and Requirements C2 Data and System Integration Branch Chief for Medical Future Concepts Center, Transformation and Training Command Major Tom Hansen said.
During the operation, knowledge of the specific equipment used for each treatment provided Soldiers with new visibility into Class VIII equipment (medical material ranging from equipment to consumables), helping units understand usage, on-hand equipment, and potential resupply requirements.
“We rarely have had visibility of patients below Role 3 care [hospital-level treatment in a combat zone], and now we can see individuals and the severity of wounds as far forward as the point of injury. This provides invaluable predictability for higher roles of care. From a Class VIII perspective, we are just scratching the surface,” Hansen said.
Transforming data
The biggest challenge for CECOM ASIC was working with shifting data structures during code and pipeline development. The BATDOK-J source data was updated multiple times during the build, including the core XML content and format.
“The team had to be flexible and adapt code and logic structures to adjust and ensure data outputs are consistent and useful,” Steve Donahue, team lead for CECOM ASIC’s Data Engineering Branch, said.
CECOM ASIC parsed streaming BATDOK-J data, standardized raw inputs into structured datasets, and implemented code for consistent, useful data visualization.
Immediate data feed analysis and display introduce a new level of visibility for battlefield medical care. Data includes when treatments occurred, injury type and treatment, severity indicators, patient information, operational context, and medical consumption data.
This is how the workflow is executed: the medic enters data on the BATDOK-J device, the data flows through servers into the Maven environment, it is processed by the integrated pipelines, and the results are displayed on a dashboard in a separate location in Palantir Maven.
Making fast, informed decisions in the heat of the battle relies on an accurate grasp of injury trends, treatments performed, Class VIII consumption, and supplies needed. With immediate data feed visibility, units gain operational awareness that was previously difficult to achieve at scale.
“Understanding treatment and Class VIII consumption as it occurs can give MEDLOG teams the data needed to ensure medical readiness,” Donahue said.
Way ahead
This marked the first effort to process and visualize BATDOK-J data at scale. The data was limited to the exercise, but according to the team, this should scale easily across Army units because the data manipulation is specific to the provided data set.
“CECOM ASIC is continually learning and building from past success to apply to new work. Internal sharing of code, pipelines, and visualizations across multiple Vantage development teams—reusing any of this can help with training and reducing future development time,” Donahue said.
CECOM ASIC will continue advancing data modernization to drive decision-making and readiness.
