On 13 August, the Ukrainian-Crimean Tatar partisan movement ATESH said its agents had disabled a communications tower near Pylna in northern Kharkiv Oblast. The group said the damage disrupted links between two Russian motor rifle regiments near the border.

Pylna lies on the Russian border and was among the villages seized when Moscow opened the northern Kharkiv front in May 2024. The claimed tower attack is part of a wider Ukrainian resistance effort behind Russian lines. Moscow's forces still depend on infrastructure in occupied territory to communicate, move supplies, and hold the line. Ukraine’s underground fighters exploit that dependence from within, targeting communications, transport, and fuel supplies to create problems for Russian units at the front.

ATESH said the tower carried data between Russian command posts and coordinated units in the area. The movement said its loss disrupted command channels and delayed border-zone mobile groups. It did not say how agents disabled the tower or how long the interruption would last.

The partisans stated that the communications between Russia’s 345th and 380th motor rifle regiments were hit hardest. The regiments operate in neighboring sectors and rely on stable links for joint action and rapid responses, according to the group. ATESH claimed their offensive tempo and ability to support each other had fallen.

Neither the claimed ATESH sabotage nor its reported effects have been independently verified.

ATESH attacks on Russian supply lines

The tower claim follows ATESH’s 10 August account of sabotaging an electric locomotive near Voronezh. The group said it carried military supplies toward the Kupiansk front in Kharkiv Oblast. In June, ATESH also said agents damaged power and rail equipment near Russia’s Novomoskovsk Azot plant, whose output feeds explosives production.

ATESH has also reported intelligence work inside Russian forces. In July, the group said an agent reported a Ukrainian strike on five military fuel trucks in occupied Luhansk. Together, the claims describe a campaign against transport, fuel, and communications behind the front.

Ukrainian resistance works behind the front

The claimed tower operation is one part of the Ukrainian resistance behind Russian lines. Underground networks also gather intelligence and sustain civil defiance. 

A Euromaidan Press investigation documented groups planting explosives, tracking Russian positions, distributing leaflets, and painting Ukrainian symbols despite the threat of imprisonment and torture.

ATESH says its network includes Ukrainians, Crimean Tatars, anti-war Russians, and sources inside Russia’s military and occupation administrations. Its claims are often impossible to verify independently. Taken together, they portray a campaign to make Russia’s rear less secure while other groups preserve Ukrainian identity under occupation.

Ukrainian partisans say they crippled a locomotive moving Russian military supplies to the front. Agents of the ATESH movement carried out a sabotage operation near Voronezh, destroying the cab of an electric locomotive used to support military transport, ATESH reported.

Disabling a single locomotive cripples the entire supply line. The locomotive was supposed to continue its journey toward the Kupiansk direction, and after the cab was damaged, operating the machine at its former pace became impossible, disrupting the schedule for forming and dispatching the next trains.

The target was a rail supply line to the front

ATESH said the sabotage hit a link in Russia's military logistics chain. The locomotive was part of the rail transport that moves Russian military cargo, and it was bound for the Kupiansk direction, one of the active sectors of the front in Kharkiv Oblast.

Russia depends heavily on railways to supply its forces. Its army moves ammunition, fuel, weapons, and heavy equipment to the front largely by rail, so the locomotives and the lines they run on are critical arteries of its war effort. A partisan network can reach them behind the front lines at a vulnerable point.

One damaged locomotive slows the whole chain

ATESH framed the value of the strike in terms of the cascade it sets off. The loss of even one link in the mainline causes delays in the delivery of ammunition, fuel, weapons, and heavy equipment.

Those delays compound at the front. When rear supply operations are interrupted, units lose combat effectiveness and suffer significant personnel losses, ATESH said, casting a single sabotaged locomotive as a blow that reaches the soldiers, depending on what it was carrying.

The strike fits ATESH's partisan campaign

Euromaidan Press cannot independently verify the Voronezh sabotage, which is ATESH's own account. But rail sabotage is a documented feature of the war behind Russian lines, and the movement's focus on the logistics that feed the front reflects a real vulnerability in an army that runs on rail.
