Continuous Ukraine 'Toll-Gate' Kill-Zone Extorts Huge 'Price' On Russian Troops

Ukraine has created what it is calling a continuous kill zone along crucial sectors of the front which are intentionally designed to act as a figurative 'toll gate' which extracts an 'extortionate' price from Russia in terms of casualties as well as destroyed weapons and vehicles.

While the aerial and land drone wall is a new Ukrainian innovation, the physical barriers of tank traps, mine fields, barbed wire entanglements etc are, ironically, based on the Russian 'Surovikin Line' which thwarted Ukraine's 2023 counteroffensive. Having learned that hard lesson, the Ukrainians are now turning their hard-won knowledge against the Russians to even greater effect as this year's disastrous Russian offensive attempts have demonstrated.

Decimus reports in Daily Kos:

Pokrovsk, Dobropiliya, Huliaipole and Kostiantynivka are exacting extortionately expensive tolls on the Russians in personnel and materiél. The Ukrainians have kept the toll gate at Pokrovsk-Myrnohrad up for more than a year and a half now.  And still make huge daily collections from the Russians. Ukrainian commanders are focusing on constraining Russian maneuverability rather than clinging to ruined towns. A new continuous kill-zone system aims to stop rapid Russian assaults through layered trenches, wider fire lanes, and anti-vehicle obstacles. This is what modern trench warfare looks like.

Ukraine’s “Toll Gate”  business  … is really booming.  The Russians can try any of the toll gates Ukraine has set up … from the south in Zaporizhia all the way up to the northernmost Sumy oblast … hoping to catch a lucky break.  Nope. 

Pokrovsk, Dobropiliya[both Donetsk & Zaporizhia oblasts], Huliaipole and now Kostiantynivka. Same result … extortionately expensive toll exacted on the Russians in terms of personnel and materiél.  The Ukrainians have managed to keep the toll gate at Pokrovsk-Myrnohrad up for more than a year and a half now.  And still making huge daily collections from the Russians in both personnel and materiél. The Ukrainians will likely keep it going for as long as the Russians are willing to pay the incredibly high toll to gain a propaganda “victory” over what is now largely pulverized concrete and a waste land.  For all practical intents and purposes the pile of rubble that is the Pokrovsk city core is now occupied by the Russians.  Beyond that and further up on the higher elevations in the north of the city and beyond lay fortified defenses  … a series of more elaborately constructed “toll gates”. 

As one fighter in Pokvrovsk recently said of Ukraine’s plans regarding the inner city:

“Our priority is not to cling to concrete,” Kovalenko explains, “but to construct a defensible perimeter on the outskirts and shape the battlefield in a way that maximally constrains the enemy’s options.”

In practical terms, this approach aims to deny Russia the ability to regenerate offensive momentum along the Dobropillia axis, prevent the opening of a new Druzhkivka-oriented line of advance, and complicate any effort to redeploy forces — particularly elements of Russia’s 8th Combined Arms Army — toward renewed operations against Kostiantynivka.

To that end, Ukrainian commanders have reportedly initiated a calculated pullback from dense urban areas to establish more defensible perimeters on the outskirts, focusing on constraining Russian maneuverability rather than clinging to ruined towns. This strategy of establishing lines behind heavily contested, destroyed urban areas is designed to better manage Ukraine’s perennial personnel shortages and counter Russian advances. This approach moves away from holding every ruined town at a high cost, focusing instead on creating deeper, more resilient defensive lines.  

The Russians had their “Surovikin Line” in 2023.  And boy did it take a toll on the Ukrainians during their abortive Summer 2023 counter-offensive. Well,  welcome to The New Donetsk Line, the major defensive network constructed by Ukraine in Donetsk Oblast, often called the "Ukrainian Surovikin Line".  This system spans well over 350 kilometers, stretching from Druzhkivka-Kostiantynivka to Sloviansk, and is designed to halt Russia’s advances following significant battlefield pressure in 2025. And it is now connected by additional works to the Pokrovsk-Myrnohrad-Dobropilia line as well.

Attribution:  A section of the elaborate defenses the Ukrainians are calling the “New Donetsk Line”.  It stretches for hundreds of kilometers from Pokrovsk up to the “Fortress Belt” cities.

There are quite a few online videos of these fortifications.  But in sum, the design features include trenches, anti-tank ditches, dragon’s teeth, barbed wire, and decentralized strongpoints hidden in forests to evade drone detection. It is modeled after the Russian Surovikin Line that stalled Ukraine’s 2023 counteroffensive, representing a strategic shift with Ukraine now on the defensive. 

The "Fortress belt". fortified since 2014, remains central to Ukraine’s defense strategy. Holding this line is vital to prevent further Russian advances toward Kostyantynivka, Kramatorsk, Slovyansk and potentially even Dnipro:

Ukraine now has the fortress belt it wishes it had in 2022

THE DEFENSIVE lines stretch as far as the eye can see, an ugly scar across the snowy hills of the Donbas. They are part of a massive fortification system that Ukrainian forces have built to protect towns and cities not yet occupied by the Russians. “If we had had such defensive lines in 2022, the situation on the ground would be the complete opposite of what it is now,” says Viacheslav Shutenko, commander of a drone battalion that is part of the 44th Mechanised Brigade.

Ukraine’s New Kill-Zone Strategy Turns Frontline Territory Into a Trap for Russians

FPV drone warfare and Russia’s meat-grinder tactics forced Ukraine to redesign its fortifications. A new continuous kill-zone system aims to stop rapid Russian assaults through layered trenches, wider fire lanes, and anti-vehicle obstacles. This is what modern trench warfare looks like.

Along those lines, attrition “toll gates” are now being set up on the Zaporizhia and the Druzhkivka-Kostiantynivka lines as well. The New Donetsk Line and the  ongoing successful Ukrainian counter in Zaporizhia presents Russia with an operational dilemma. Russia is going to soon have to make a decision as to which attritional gate to go into  … continue pushing the Southern Line which had been making gains until Ukraine slammed the door shut and started rolling it back or go whole hog and all-in against the “New Donetsk Line” in a do-or-die attempt to militarily capture the rest of Donetsk oblast?.  Ukraine intentionally set it up like that. Indeed even the ongoing southern offensive was planned not as a major counteroffensive but as part of the overall effort to stabilize and harden Ukraine’s frontline defenses ahead of Russia’s 2026 Spring-Summer offensive: 

A regiment commander says Ukraine’s recent advances were a tactical operation to stabilize the front — not the sweeping counteroffensive being celebrated online.

... Ukraine's Defense Forces launched an offensive aimed at improving the tactical and operational situation on this front sector, stabilizing it, and blocking Russian advances. Filatov[Dmytro “Perun” Filatov], commander of the 1st Separate Assault Regiment was specific about what it was not:

"This is not some grand counteroffensive that everyone is shouting about. This is operational level. Maybe a little more."

In that regard, any continuing gains from the Huliaipole-Oleksandrivka front in the south, such as General Syrskyi described today is just extra gravy:

It is worth noting that Russia pounced on the Huliaipole area because it was for a long time one of the least defensively built up sections of the Ukrainian southern flank … basically left to a couple of lightly-armored Territorial Guard brigades, the 102nd and 106th, anchored on the Haichur River as a defensive strong point.  Ukraine has now managed to get the opportunity to rectify that omission … to harden what had been relatively weak defenses in this sector.

But according to analysts, Ukraine’s Zaporizhia counter, as designed, has also had the effect of frustrating and upending Russia’s new offensive plans. The Institute for the Study of War (ISW) assessed that these counterattacks spoiled Russia’s offensive timeline and forced the redeployment of elite Russian units from the eastern front to the south as well as disrupted Moscow’s plans for a spring-summer 2026 offensive toward Zaporizhzhia City and the “Fortress Belt” in Donetsk :

Ukrainian Armed Forces counterattacks thwart new Russian offensive on the front

The American Institute for the Study of War (ISW) concluded that a counteroffensive by Ukrainian defenders could have thwarted Russia's plans for further advancement in the Zaporizhia region, as well as the expected spring-summer offensive of the Russian Federation on the "Belt of Fortresses" in the Donetsk region.

Thus, Ukraine's counteroffensive in February 2026 could have thwarted Russia's plans to further exploit tactical successes in the Zaporizhia region, and could also have negatively affected the expected spring-summer 2026 offensive on the Ukrainian "belt of fortresses," the ISW team emphasizes.
