When a building is full of Russians, send in an FPV drone first!
Tiny first-person-view drones are everywhere all the time over the 1,100-km front line of Russia’s 43-month wider war on Ukraine. But most of them are surveillance and attack assets. They scan for targets over or near the front line—and then zoom in and explode.
Now at least one Ukrainian unit is finding a new use for the ubiquitous FPVs. The 225th Assault Regiment, holding the line outside Vorone in southern Ukraine’s Dnipropetrovsk Oblast with its M-2 Bradley fighting vehicles, has begun attaching FPVs to infantry squads to help the squads clear buildings of Russian troops.
“Clearing buildings is deadly—an enemy can be in every corner,” the regiment explained. When the infantry must enter a structure, they can send an FPV “to scout ahead.” “If the enemy is found,” the regiment explained, “the drone strikes, keeping our infantry safe.”
It’s delicate work requiring extreme precision on the part of the distant drone operator, who wears a virtual-reality headset to see what the warhead-clutching FPV sees. An FPV explodes on contact with any surface, so an imprecise maneuver can endanger the drone’s human squadmates.
To guarantee an uninterrupted signal between the operator and their drone, the 225th Assault Regiment uses fiber-optic FPVs for clearance missions. Fiber-optic drones send and receive signals via kilometers-long optical fibers, making them impervious to radio jamming and the signal dead zones created by buildings or hills.

Drones as suppressive fire
The Ukrainians aren’t the only ones innovating with their smallest drones. The Russians have new ideas, too. FPVs are so dangerous—and so terrifying—that soldiers tend to duck into their trenches as soon as they hear the drones’ distinctive buzzing. For that reason, some Russian regiments use the drones as suppressive fire.
Suppressive fire is an infantry tactic that’s as old as gunpowder. Basically, it means shooting at the enemy with something—rifles, machine guns, mortars or artillery—with enough intensity to drive the enemy underground for as long as it takes friendly forces to “breach” the enemy’s defenses … and advance.
Drones can suppress the enemy without even striking. “Soldiers begin to hide from the sound of UAVs alone and do not leave cover for a long time,” Russian blogger Unfair Advantage wrote.
“If the enemy is accustomed to being afraid of drones, then a UAV ‘carousel’—that is, the successive replacement of one strike UAV with another, can lead to the effect of suppressing positions, despite significant time intervals between strikes,” Unfair Advantage explained.
Infantry should begin their movement to contact with the enemy during an initial wave of drone attacks. “After the strikes are completed, the infantry takes cover and waits for the next wave of UAVs to arrive—or continues to move, but out of the line of sight of the defenders,” the blogger wrote. “This is repeated several times until the infantry reaches the immediate vicinity of the attacked position.”
There, the attackers wait for more drones before making their final push through the enemy positions. Drones should be overhead the whole time during the breach—”a mixed carousel of observation UAVs and attack UAVs,” Unfair Advantage advised.
To prolong the endurance of any turn of the UAV carousel, the operators can land some drones on the ground or on rooftops, idling their engines but keeping their cameras on—thus preserving the robots’ batteries. As long as at least one drone is audible by the defending infantry, the infantry should keep their heads down. They should, in other words, remain suppressed.
The respective new drone tactics belie deepening manpower problems on both sides of the wider war. More and more, both the Ukrainian and Russian armed forces are counting on robots to perform tasks most militaries still assign to human beings.
Ukraine’s manpower shortage is well-known. It’s possible Ukrainian brigades are short 100,000 trained infantry. But Russia has too few troops, too—despite generous bonuses and deceptive recruiting practices that lure or trap tens of thousands of fresh enlistees every month. Overall, Russian regiments probably have plenty of soldiers. But like Ukrainian brigades, they may specifically lack trained and experienced infantry.
Why risk them on a mission that a robot with a skilled operator can handle?
