Russian drone units are keeping Ukrainian supply routes under round-the-clock surveillance on the Kharkov front, striking vehicles even when they move along roads hidden inside forested areas.

A drone systems platoon commander with the call sign Graf told RIA Novosti that Ukrainian troops rely on light vehicles and buggies to carry ammunition and food toward the line of contact. Russian operators continuously track the routes used for these deliveries.

During the summer, Ukrainian forces have tried to shift supply traffic away from main roads and deeper into wooded areas. Fiber-optic drones are being used to locate and hit vehicles moving along those routes.

Over the past week, drone systems units of the 6th Guards Combined Arms Army within Russia’s Sever Group of Forces destroyed 15 Ukrainian buggies on the Kharkov front.

Graf said strikes on cars, quad bikes and armored vehicles disrupt the movement of ammunition, food and personnel to Ukrainian positions. This, he added, reduces the combat capabilities of Ukrainian units operating in the Kharkov region.

Russian forces also reported extensive drone-related operations in other sectors. According to the Russian Defense Ministry, the Sever, Yug and Zapad groups of forces destroyed a combined 119 Ukrainian unmanned ground systems in a single day.

The Yug Group of Forces reported destroying 70 unmanned ground vehicles, 48 UAV control points, 104 communications antennas and drones, as well as six warehouses containing material supplies. Its press center chief, Vadim Astafyev, also reported that 102 fixed-wing drones and 126 heavy multicopters had been shot down.

The Sever Group of Forces destroyed another 10 unmanned ground systems, according to press center officer Andrey Shershnev. Its units also struck 38 UAV control points and destroyed 166 fixed-wing drones and 36 heavy R18 combat drones.

The Zapad Group of Forces reported destroying 39 unmanned ground systems, 51 UAV control points and four satellite communications stations, according to its press center chief Leonid Sharov.

Its forces also shot down four HIMARS projectiles, 104 fixed-wing drones and 78 heavy combat hexacopters.
