Drones have pushed armored vehicles off the roads to Ukraine's front line, a Ukrainian brigade commander told RBC-Ukraine. Denys Perch, who commands the 107th Territorial Defense Brigade, says the drone-saturated belt has grown so deep that pickups no longer reach forward positions. The one enemy weapon his jammers can't touch is the fiber-optic drone.

The war has become a contest over who can pull people off the battlefield fastest, as cheap drones make any human movement near the front a target. Ukraine keeps out-inventing Russia at the front, but Russia copies each advance and floods the line with it at state scale.

When armor becomes the target

Until recently, armored vehicles still drove supplies to logistics hubs near the front. That is now almost impossible. Perch says that when a large, armored machine appears, Russian forces treat it as a prize target and swarm it with dozens of drones and munitions. Perch would sooner park his armor than seat soldiers inside it.

A kill zone that keeps widening

On the busiest sectors, Perch says, the kill zone—the drone-ruled strip around the contact line—now runs 15 to 20 kilometers deep. Some positions take three days to reach on foot. Where troops once drove most of the way and walked the last stretch, they now walk it all.

Robots take the drive

Under Perch, the brigade climbed, by his account, from around 22nd to third among Ukraine's Territorial Defense forces on the military's strike-results leaderboard, the home-guard units now fighting on the front. Ground robots—unmanned ground vehicles (UGVs)—do the work that armor cannot. They haul supplies and evacuate the wounded, though the robot often can't be brought back. His brigade runs over 1,500 logistics missions a month by heavy bomber drones alone, and still more by first-person-view (FPV) drones and robots. Russia hunts those bombers, he says, with interceptors that scramble the moment they hear one take off, so his crews mix high and low flight to slip past. Perch expects robots to move from supply runs into combat, hitting Russian troops in their rear.

The drone his jammers can't touch

Both armies now field fiber-optic drones—machines guided by a hair-thin glass thread instead of radio. No signal means nothing to jam. Ukraine learned to block radio and digital drones, cutting their controls and video, Perch said. The glass-fiber ones his electronic warfare cannot reach, because there is no radio link to attack. His brigade still has no counter to them, Perch said, and he wants a technical fix that stops them.

The Security Service of Ukraine (SBU) has arrested two individuals in Kyiv accused of attempting to extort $200,000 from a European defense company, potentially jeopardizing the delivery of electronic warfare (EW) systems to Ukraine's military, the SBU reported on June 14.

The suspects allegedly demanded the payment in exchange for facilitating the successful testing and adoption of five radio electronic warfare systems provided to Ukraine at no cost, according to statements released by the SBU and the Prosecutor General's Office.

The devices, supplied by a private foreign manufacturer, were financed by Ukraine's international partners. The producer had already delivered five systems to Ukraine, with additional contracts possible if the equipment performed well in combat conditions, the SBU said.

According to investigators, the suspects falsely claimed to have influence within Ukraine's Defense Ministry and promised to use their connections to ensure positive evaluations of the equipment.

"Under the guise of having contacts within the ministry, the men demanded $200,000 from the company in exchange for ensuring no obstacles during official trials of the equipment," the Prosecutor General's Office said in a statement.

Both men have been formally charged under Ukraine's Criminal Code for alleged obstruction of the Armed Forces and receiving unlawful benefits through influence peddling. The charges carry a possible sentence of up to eight years in prison and asset confiscation.

The arrests were made as part of a broader investigation led by the SBU and conducted under the procedural oversight of the Specialized Defense Prosecutor's Office. Authorities say the investigation is ongoing to identify all individuals involved.

Ukraine continues to rely heavily on international military assistance as it defends against Russia's full-scale invasion, now in its fourth year. Ukraine uses EW systems during Russian attacks on its cities and on the front line.

Kyiv and its Western partners launched an electronic warfare coalition in April, which consists of 11 countries and comes on top of other eight Western coalitions to support Ukraine. Other similar initiatives include an artillery coalition, a fighter jet coalition, and a demining coalition, organized within the framework of the Ramstein format.
