What Enemy Drones Do

In April 2025 the Maneuver Center of Excellence approved a new platoon battle drill: 07-PLT-D8015, React to Unmanned Aircraft System While Dismounted. It sits next to React to Contact and React to Indirect Fire in the drill list, and it is there because a seven-dollar quadcopter is now the most common way an infantry platoon gets found and the first link in the chain that gets it killed. The Army built the drill around ATP 3-21.8 and ATP 3-01.81, and its own coaching point is blunt: enemy drones are very difficult to defeat with direct fire, so practice this until the platoon has it cold.

The drill breaks the threat into what a small UAS is actually doing over you. It is a reconnaissance platform — a camera, increasingly a thermal camera, feeding an operator who is looking for exactly what you look like. It is an observer for indirect fire, which is the role that kills the most people: the drone finds you, the guns do the rest, and in Ukraine the time from a drone spotting a target to rounds landing on it has been cut to one to three minutes. It is a strike platform — a first-person-view drone that flies into you at seventy kilometers an hour, or a quadcopter that drops a grenade. And it is an electronic warfare platform that can locate the platoon by the radios and phones it is carrying.

The jammer-proof drone. Since early 2025 both sides in Ukraine have flown FPV drones that trail a hair-thin fiber-optic cable off a spool instead of using a radio link — up to twenty kilometers of it. There is no signal to jam, so a Dronebuster does nothing to them, and they fly into trenches, bunkers, and buildings where a radio drone loses its link. The Center for Army Lessons Learned put out a Soldier-level primer on them in August 2025 and was blunt that current counter-UAS gear can barely touch them. What they give away: they are heavier and louder than a radio FPV, the cable glints in daylight and stands out in infrared, and a drone that circles an object tends to snap its own line. Ukrainians being chased by one try to get it wrapped around a tree.

The kill zone. The Irregular Warfare Center’s May 2026 field study puts the small-drone kill zone at ten miles and more behind the line of contact; one Ukrainian brigade commander said it ran twenty to twenty-five kilometers in his sector and that his infantry walked twenty-five kilometers to their positions, choosing the weather and the hour, taking three days to a week to get there. Ukraine’s military claimed 96 percent of the Russian casualties it inflicted in March 2026 came from tactical drones. Inside that zone, units move on foot, in small groups, at night, and with escorts: “guides” who pathfind and “stalkers” whose whole job is to hunt drones off the column with shotguns and machine guns. That is where the air guard in this drill comes from. The other thing the study says is worth hearing before the animation: artillery can be acclimatized to, a drone attack cannot. It is single combat against the operator, and it feels like being hunted, because you are.

The JMRC opposing force at Hohenfels runs a dedicated drone platoon against every rotation, trained by Ukrainian brigades straight off the front. In one rotation it executed thirty-four fire missions on units it found from the air, most of them on troops or vehicles in the open. A battalion command post set up outside the treeline took a drone strike, started treating casualties in the open, and the same operator called fire on the aid point and produced a mass casualty. A platoon that popped smoke the moment it spotted the drone and moved broke contact clean. That is the whole spread of outcomes, and the drill is what separates them.

Don’t Be Seen

The drill starts at detection, but the fight starts earlier. The battle drill’s own note on passive protection is two lines: camouflage and signature discipline, including overhead concealment and infrared-blocking material like thermal or emergency blankets with the non-reflective side facing the threat; and short transmissions with brevity codes, because the electromagnetic spectrum is a sensor too. The JMRC drone teams put it more simply: if you can be seen, you can be killed, and cover and concealment is the core counter-UAS principle.

The Army’s five words for it. The CALL fiber-optic primer boils the passive fight down to predict, detect, avoid, protect, deceive. Predict where the operators have to set up and watch those spots. Detect by listening — and remember the fiber-optic drone is louder and its cable shows in IR. Avoid by hiding in more than one part of the spectrum: visual camouflage and IR-blocking material together. Protect by digging in with overhead cover, no straight lines, and nets draped over openings so a drone that gets there tangles instead of entering. Deceive with realistic decoys — fake positions, fake vehicles, camouflaged the way a real one would be, because a decoy sitting in the open fools nobody.

The spectrum. Some enemy drones carry radio reconnaissance gear that fixes a position off clusters of phones, radios, Wi-Fi, and Bluetooth. Phones off and in flight mode, radios set away from the leaders and kept short, and brevity codes on the net. If you have your own drone, put it up over your own position and look at yourself — whatever you can see, the enemy can see.

The Full Sequence

1. Movement. The platoon is moving in a squad column, fire team wedges, with air guards assigned by sector the way ground sectors are. The company order gave the PL the UAS threat, the air defense status, and the engagement criteria. Every Soldier is a sensor; you will hear a drone before you see it, and a good pilot brings it in out of the sun and downwind so you hear it late.
2. Detection and contact report. The Soldier who detects it alerts his squad leader: announce contact, freeze, then give direction, distance, description, and altitude if he can judge it. He does not move — the drone may not have seen the platoon yet, and movement adds to the signature. If the platoon is already being fired on, it returns fire and breaks contact.
3. Freeze, eyes only, SPOTREP. The squad freezes and observes; the squad leader passes the report to the PL; the rest of the platoon freezes on hearing it and scans with their eyes only, no faces up. The PL sends the initial SPOTREP to the company.
4. Identify. The PL determines friendly or enemy. Higher may already know; until then it is hostile. He reads the flight: straight means en route, a pattern means searching, loitering means it has found something.
5. Assess: crossing. A drone crossing the platoon’s area gets nothing from it: freeze, do not move, camouflage, cover, and concealment. Crouch in the open, minimize the shadow, get a tree between you and it in the woods. If it keeps going, let it go and continue the mission.
6. Assess: hovering. A drone that comes back and loiters has seen the platoon. The PL orders hasty positions with cover and concealment between the Soldiers and the aircraft, and evasive movement if that is what it takes to get there.
7. Seek cover and disperse. Soldiers in the open move to the nearest cover along a covered route, not a straight line across the field; they change direction every seven to ten meters and keep their spacing. Soldiers already in the trees spread out too — each fire team into the woods on its own side, squad leaders between their teams — because a column under canopy is still a column. Thermal blankets go up.
8. Decide. The PL decides whether to engage, weighing the mission, the tactical situation, and adjacent units. Good concealment, high altitude, and rifles alone favor staying quiet. A compromised platoon, a low and close drone, and engagement criteria met favor shooting. UAS defeat systems come before organic weapons if the platoon has them.
9. Engage. Everybody who can reach it fires together at a controlled rate, from one side of the aircraft with every muzzle up and nobody downrange, using the football-field technique for the aiming point and hasty supports — trees, the ground, a teammate. Leaders control the fire and call it off if the drone drops below the treeline; they do not shoot.
10. Updated SPOTREP. The squad leader sends the PL a SALUTE report on the drone: size, activity, location, unit type, time, equipment. A downed drone is unexploded ordnance. Nobody touches it.
11. Protective action. The PL requests immediate suppression on the threat if there is a target — the operator, the launch site, the observation post. He requests obscuration and puts up smoke to cover repositioning. He requests a radar critical friendly zone over the position.
12. Break contact. The platoon leaves the grid, off its old route and off the obvious next terrain, with wider spacing and changes of direction. Breaking line of sight forces the drone to search again on a battery that is running out. The PSG counts the platoon out.
13. New ground. Dispersed perimeter under canopy, thermal blankets, no fresh dirt, radios away from leaders, phones off, no walking between positions. Count from team leader to squad leader to PSG to PL; medic checks everyone.
14. Report status. The PL reports accountability, casualties, ammunition, the downed drone’s grid, and the new position to the company, then continues operations per the order and the commander’s guidance.
15. Resume movement. New azimuth, under the trees, off the trail, spacing wide. The sky is a sector now.

Shooting a Drone

Start with the honest part: small arms rarely bring down a drone, and the battle drill says so. Shooting also announces the platoon to every enemy in earshot, and a miss does nothing but that. So the decision is the PL’s, and he makes it against the engagement criteria in the company order, the type and altitude and distance of the aircraft, and where friendly units are. The drill’s own rule of thumb is that a confirmed threat drone within close range gets engaged.

Once the decision is made, the drill is specific about how. UAS defeat systems come first — a Dronebuster jammer or a Smart Shooter fire-control optic if the platoon has them; a jammed drone often turns for home, and watching where it goes can give you the operator. The caveat the drill has not caught up to yet: a fiber-optic drone has no radio link, so the jammer does nothing to it. If the drone keeps coming through the jammer, assume that is what it is and go straight to the guns. Then short-range weapons like a shotgun. Then the organic weapons: the M4, the M249, the M240. The Ukrainian lesson is that it takes multiple weapons firing together to create a cloud of fire with any real chance of a hit. One rifleman is a noise; a dozen shooters are a chance.

If it comes down. It is unexploded ordnance until EOD says otherwise. The Ukrainians add that downed drones are routinely rigged to detonate when handled. Mark it, report the grid, and leave it. And understand what you have and have not accomplished: the operator watched his drone die and knows exactly where you are. Killing the drone buys time; it does not buy safety. The next step is still smoke, suppression, and getting off the grid.

Signals & Reports

The drill is driven by three reports, and every one of them is short. Long transmissions are a signature; brevity codes and the fewest words that carry the information are the standard.

Common Mistakes

• Looking up. The whole platoon hears it and forty faces turn toward the sky. Faces, eye protection, and optics all reflect light and glow on thermal. The drill says eyes only, scanning your sector.
• Running. Movement is the first thing a camera picks up. The Ukrainians are blunt about it: do not run to your positions when you see a drone, because you will show it where the positions are. Freeze first; move to cover along covered routes only when the PL says so.
• Going prone in the open. It feels right. From directly above, a prone Soldier is a longer, wider shape than a kneeling one. Crouch.
• Straight-line sprints to cover. A drone operator dropping on a man running straight only has to lead him. Change direction every seven to ten meters.
• Bunching up. Under a drone, the platoon that stays spread out loses one man to one munition; the one that clusters at the treeline loses a team.
• Shooting without the order. A rifleman opens up at a drone three hundred meters up, misses, and announces the platoon to everything in earshot. The decision to engage belongs to the PL and is made against the engagement criteria.
• Shooting across the formation. Two treelines open up on a drone between them and the rounds that miss land on the other treeline. Get every shooter on one side of the aircraft, muzzles up, and cease fire the moment it drops low.
• Trusting the jammer. The Dronebuster comes up, the drone keeps coming. It is on a fiber-optic cable and never heard you. Have the guns ready before you find out.
• Shooting at where it is. Rounds fired at a moving drone arrive where it was. Lead it — half a football field for a crossing aircraft.
• Treating the kill as the end. The drone goes down and the platoon relaxes. Its operator knows the grid, and the fire mission is already on the way. Smoke, suppression, move.
• Walking out to the wreck. It is UXO, and enemy drones are rigged to go off in your hands.
• Staying put. The platoon that was found and does not move is the target. Break line of sight, get off the predictable ground, make the enemy find you again.
• Treating casualties in the open. The JMRC command post that took a drone strike, then set up an aid point outside the treeline, took a fire mission on the aid point. Casualties get treated under cover, dispersed.
• Long transmissions. The drone that found you may be listening for radios. Brevity codes, short reports, and radios kept away from the leaders.
• No drill at all. The company order never briefed the threat, the air defense status, or the engagement criteria, so the PL is inventing the decision under a hovering drone with ninety seconds to live. Rehearse it like React to Contact, because it is one now.
