The U.S. military revealed this week that it used an Unmanned Surface Vessel, often called a sea drone, to rescue two U.S. Army crew members of an AH-64 Apache helicopter downed by Iranian forces in the Middle East. While the rescue marks the first publicly known occasion that an autonomous surface vessel has retrieved U.S. troops, it is part of a broader ongoing trend to use drones on the battlefield for life-saving purposes.
Drones of all types are steadily being integrated into rescue missions for several reasons. Unmanned systems on land, in the air, and above and below sea can safely extend human presence into areas that are hazardous to human life.
Drones offer surveillance powers and physical reach to human operators, plus increasing artificial intelligence capabilities that rapidly condense data for human consumption. Many unmanned systems are also self-navigating. These qualities are bringing them to the forefront of new techniques in combat casualty care.
Unmanned Aircraft Systems are being used for search and rescue missions and to transport medical supplies. The Texas National Guard used drones to respond to the flooding of the Guadalupe River last year and since then prepares its drone operators for storm responses.
Combat medics of the Oregon National Guard trained with drones for the first time last February to fly blood supplies into hazardous areas. In May of this year, U.S. Army troops in Poland practiced strapping test dummies to a large quadcopter drone to test casualty evacuation by air.
Similarly, Unmanned Ground Vehicles are being tested for evacuating casualties from combat zones. Ukrainian and NATO forces have been using UGVs to perform what in the past was the duty of military stretcher bearers – a trend that shows no signs of stopping.
The U.S. Army recently called for a UGV capable of transporting supplies and casualties across “the last tactical mile,” and conducted an exercise called Panther Avalanche that saw UGVs used to evacuate soldiers and distract enemy forces as decoys.
During a September 2025 exercise, the Defense Advanced Research Projects Agency held a triage challenge to test the abilities of drones to cooperate with humans in responding to casualties. During the exercise, robotic dogs performed triage assessments of combat injuries.
The recent rescue of U.S. service personnel by a Unmanned Surface Vessel demonstrates how these self-maneuvering drone boats can function to remove humans from harm’s way.
Drone boats come in many varieties and sizes. Most are equipped with arrays of cameras, sensors and rugged navigational equipment that allow them to continue sailing over rough waters and reach areas that would be difficult for manned vessels to get to. Last year, the Pentagon linked autonomous surface vessels with its global command and control network to significantly expand the reach of the U.S. Navy.
Drones are commonly thought of and used as weapons, but are consistently demonstrating great potential as life-saving equipment. They are quietly but quickly transforming military medicine and erasing age-old practices that were taken for granted.
Military history has given us countless images of soldiers carrying wounded comrades from the heat of battle. There is no question that soldiers will continue to learn how to safely evacuate casualties themselves and that injured military service members will always require human aid. Going forward, they are more likely to do so in increased cooperation with drones and at minimal risk to their own lives. As technology continues to reshape warfare at all levels, it is not improbable to envision a future in which soldiers are carried from combat zones by robots.
