Today, there are a lot of interesting updates from the Kupiansk direction. Here, along the Oskil River near Kupiansk, Ukrainian special forces just carried out one of the boldest operations of the war.

In a surprise helicopter raid deep behind Russian lines, they landed undetected and tore through dugouts, safe houses, and staging zones, shattering Russian preparations before their offensive could even begin.

Hidden danger of Kharkiv Oblast town

The Russian forces in this area maintain a very thin bridgehead on the west bank of the Oskil River, where the control of the town of Dvorichna allows them to accumulate and deploy forces across the river.

Russians plan to use this bridgehead to tactically outflank Ukrainian forces in Kupiansk from the north, as well as to use it as a launching pad to link up with their other offensive in Kharkiv.

The Ukrainians understand that the Dvorichna bridgehead will be a key staging ground for the Russian summer offensive in Kharkiv, and know that they must act quickly to undermine any future Russian effort here.

The flaw in the river

The primary Russian weakness here is that their forces must cross the Oskil River by boat to reach their bridgehead on the western bank, which significantly complicates their logistics. This prevents them from deploying large numbers of heavy weapons such as anti-tank guided missiles or MANPADS.

The lack of man-portable air defenses makes the Russian bridgehead highly vulnerable to any aerial operations that the Ukrainians could conduct.

Subsequently, the Ukrainian special operations forces command devised a daring and unconventional plan, to conduct the first air assault operation in the war in over three years.

They planned to fly over Russian lines and deploy several teams of special forces in the rear of the enemy, where they would conduct raids, gather intelligence, and direct fire onto concealed Russian deployment points.

Ghosts in the trees

The Ukrainian Special Forces involved in this operation were deployed using American UH-60 Black Hawk helicopters, flying low to avoid being detected by the Russians.

Penetrating deep behind Russian lines, the helicopters were able to land and dismount several dozen Ukrainian operators before returning safely to friendly territory.

Once on the ground, the Ukrainian troops moved quickly and with purpose. After reaching their targets, they launched a series of highly effective and deadly raids against Russian forces. They cleared forest belts and residential areas of enemy soldiers who had been preparing to cross the river.

Russian troops were caught completely off guard, never expecting an attack from their rear. Several dugouts were quickly encircled, and numerous Russian soldiers were captured in the confusion.

Taking full advantage of surprise and terrain, Ukrainian operators concealed themselves in forested areas, waiting for small Russian infantry groups that were either sent to find them, or were moving to new positions completely unaware.

These ambushes were swift and lethal, as the Ukrainians eliminated enemy soldiers at point-blank range using small arms, all while remaining undetected in the dense cover of the forest.

The escape corridor

The high level of coordination and preparation of the Ukrainian forces included several armored vehicles, meant to arrive near a designated exfil point to quickly evacuate the operators. This point was chosen carefully, as it had the least amount of frontline activity, and no Russian bridgehead, making it the safest route for the job.

The Ukrainians moved through the dense forests behind the Dvorichna bridgehead and avoided areas with larger concentrations of Russian soldiers.

The Ukrainian special operators, with intelligence gained from captured Russians, enabled the Ukrainian drone operators to identify large Russian strongholds standing in the way of the Ukrainian exfiltration.

Artillery crews and heavy drone bombers were deployed, leading to the decimation of these Russian troops.

This focused fire established a corridor for the Ukrainian special forces to safely traverse the forests and reach the western bank of the river, where MaxPro armored vehicles awaited to exfiltrate them back to safety.

Operators left behind: the shadow war begins

Overall, the Ukrainians achieved the impossible, carrying out the war’s first air assault operation in over three years, allowing them to strike deep into Russian-held territory, inflict serious losses, and gather critical intelligence.

Notably, it is highly likely that not all Ukrainian operators exfiltrated from behind Russian lines.

According to special forces doctrine, these operators will be able to gather intelligence, set up and train further resistance networks, and conduct a deadly guerrilla warfare with sabotage and liquidations of top Russian commanders.

Russia is going to go all-in this summer, and the Ukrainians are positioning themselves to take every advantage they can to repulse it.
