REPORT: Ukraine advances on two fronts as Russia throws its reserves into combat

Introduction: Two breakthroughs that shift the tactical landscape

The front gives way at Borova and Kostyantynivka

The week of June 9, 2026 will be remembered in the archives of this war. The Institute for the Study of War (ISW) confirmed that day that Ukrainian armed forces had advanced on two distinct sectors of the front: the Borova area in Kharkiv oblast, and the tactical axis Kostyantynivka-Druzhkivka in Donetsk. This is no trivial development. In a war of position where every kilometer is paid for in blood and steel, a simultaneous double advance signals an operational imbalance on the Russian side.

Geolocated images published between June 4 and 8, 2026 concretely document these movements: confirmed Ukrainian gains at Karpivka, east of Serednie, and northwest of Zelena Dolyna. Maps do not lie. These are territories recaptured, Russian defensive positions overrun, and a momentum accelerating despite all the losses endured.

Russia scrambling to plug its own gaps

To understand these Ukrainian advances, one must look at how Russia is responding. The ISW notes that Moscow is now committing rear-area units to plug the gaps at the front — troops normally assigned to logistics, support, or security duties, pushed into the front line out of tactical desperation. This is a telling sign of the fragility of Russian reserves after more than four years of attritional warfare.

Russian military sources themselves confirmed on June 14 that Ukrainian counterattacks had retaken part of Borivska Andriivka, northeast of Borova. When the enemy acknowledges its own retreat, the situation is serious.

Borova: the key to Kharkiv oblast

Geographic position and strategic value

Borova is a small town in Kharkiv oblast, in northeastern Ukraine, less than 30 kilometers from the Russian border. Its value is not symbolic — it is logistical. Whoever controls the road networks around Borova can threaten Russian supply lines running through the region from Luhansk oblast. It is a node in a vital network for Moscow.

The Borova River, which runs through the area, creates a natural constraint for both sides: crossing a waterway under enemy fire remains one of the most perilous exercises in modern warfare. The fact that Ukrainians managed to advance despite this obstacle speaks to an increasingly refined combined-arms coordination — artillery, reconnaissance drones, assault infantry.

Karpivka, Serednie, Zelena Dolyna: the geolocated evidence

Geolocated images released by open-source analysts between June 4 and 8, 2026 constitute irrefutable evidence. At Karpivka, Ukrainian positions advanced eastward. East of Serednie, Ukrainian troops were photographed or filmed in areas previously held by Russia. Northwest of Zelena Dolyna, the shift in the line of contact is visible on independent tracking maps.

These advances, modest as they are in kilometers, represent a considerable effort. Every meter of ground gained in the Borova zone is a meter Russia must retake — if it is capable. The Russian counterattacks documented on June 14 at Borivska Andriivka show that Moscow is trying to respond, but its successes remain partial and costly.

The Kostyantynivka-Druzhkivka axis: the battle for central Donetsk

An axis under strain for months

In Donetsk, the Kostyantynivka-Druzhkivka axis is one of the most fiercely contested sectors along the entire front. These two industrial cities form a corridor whose loss would jeopardize Ukraine's defense of the entire region. Russian forces had spent weeks pushing toward Kostyantynivka, knowing that the fall of that city would open the road to Druzhkivka and beyond toward Kramatorsk.

The Ukrainian advance confirmed by the ISW on June 9 along this axis therefore carries considerable strategic weight. It indicates that the defenders are not waiting passively — they are seeking to regain the initiative, pin the enemy on its own positions, and prevent it from concentrating forces for a decisive push toward Kostyantynivka.

The dynamics of local counteroffensives

Ukrainian tactics in June 2026 appear to rest on a proven principle: multiply friction points to dilute Russian offensive capabilities. By attacking on two fronts simultaneously — Kharkiv and Donetsk — the Ukrainian army forces the Russian command to arbitrate constantly: reinforce here or there, knowing that reinforcements sent to one sector inevitably weaken another.

This approach requires the logistical coordination and operational intelligence that the Ukrainian army spent years developing. With NATO support in intelligence and planning, Ukrainian operations have reached a level of sophistication that is confounding Moscow. The rear-area units dispatched as reinforcements on both axes are proof of that.

Russian reserve units: a red flag

When the rear becomes the front line

The information confirmed by the ISW on the commitment of Russian rear-area units to the front deserves careful attention. These units — logistics, engineering, communications, security — are not normally trained for close combat. Sending them to plug gaps against battle-hardened Ukrainian assault troops is sending them to their deaths.

This tells us something essential about the state of Russian operational reserves. After more than four years of war, after losing over 1.3 million soldiers according to Ukrainian estimates, Russia is scraping the bottom of the barrel. It is sending undertrained men into a front that does not forgive improvisation. The human losses that follow only deepen the spiral.

The "meat wave" strategy and its limits in 2026

The Russian strategy of sending human waves — dismissively dubbed "meat waves" in Western and Ukrainian media — revealed its operational limits as early as 2023. It can saturate a defensive line, force local retreats, but it does not create strategic breakthroughs. It generates colossal Russian losses without decisive advances.

In June 2026, that limit is even more visible. Ukrainian FPV drones, precision artillery systems provided by the West, and an active defense doctrine combining calculated withdrawal with immediate counterattack have made Russian human waves even more costly. Sending rear-area units into this environment amounts to tactical recklessness — or desperation.

Borivska Andriivka: the June 14 counterattack

What Russian sources confirmed

The most significant confirmation of Ukrainian advances came, paradoxically, from Russian military sources themselves. On June 14, 2026, those sources acknowledged that Ukrainian counterattacks had recaptured part of Borivska Andriivka, in the northeast sector of Borova. This locality had previously been under Russian control or was contested.

When the opposing side acknowledges your advance, the informational value is at its maximum. This is no longer Ukrainian propaganda, nor announcements from Kyiv's Ministry of Defense that might be biased — it is an enemy admission. In the information war that accompanies every armed conflict, that is a rare asset.

The battle for the villages northeast of Borova

The northeast sector of Borova includes a series of villages and hamlets whose names have become familiar to conflict analysts: Borivska Andriivka, Karpivka, the axes leading toward the river. Each of these points is a defensive position, a firing angle, a potential shelter for an infantry section. The war plays out here at the village level, sometimes at the house level.

Ukrainian forces advance here by combining preparatory artillery strikes with assaults by small mobile units, supported by reconnaissance and attack drones. The coordination between these different components is what sets the 2026 Ukrainian army apart from that of 2022: it has learned, adapted, and strikes with a precision that Moscow can no longer ignore.

The ISW as an independent verification tool

The Institute for the Study of War's methodology

The Institute for the Study of War (ISW), based in Washington, has published a daily assessment of the Russian offensive campaign since the start of the large-scale invasion in February 2022. Its analyses draw on open sources — satellite imagery, geolocated videos, official statements from both sides, independent sources — and are widely cited as a reference by Western media and governments.

It is not a perfect tool. The ISW operates within a context of fog of war, acknowledges its limitations, and clearly distinguishes between what is confirmed and what is probable. But in a conflict where both sides lie extensively for propaganda purposes, an organization that systematizes geolocated verification is a valuable public service.

The role of independent open-source analysts

Alongside the ISW, an ecosystem of independent analysts — on Telegram, X (formerly Twitter), and various platforms — contributes to front-line information verification. Accounts like DeepStateMap and analysts like Oryx for destroyed equipment have revolutionized loss transparency in this conflict. It is thanks to them that the images from June 4 to 8 could be geolocated and integrated into the ISW's assessment.

This collective, decentralized, largely volunteer work constitutes an informational counteroffensive that complements Ukrainian military efforts. Moscow's lies are now corrected in near real time. This is a structural change in the way wars are documented, and it clearly plays in favor of Kyiv.

The global context: Russia running out of steam

Indicators of Russian exhaustion in June 2026

The Ukrainian advances at Borova and Kostyantynivka-Druzhkivka do not occur in a vacuum — they occur within a broader context of steadily deteriorating Russian capabilities. In June 2026, exhaustion indicators are mounting: rear-area unit commitments, daily losses exceeding 1,200 soldiers according to Ukrainian General Staff estimates, recruitment difficulties despite increasingly high bonuses, and logistical infrastructure targeted by Ukrainian strikes.

Ukraine's deep-strike campaign against Russian refineries — notably in the Urals, more than 2,000 km from the border — is also creating fuel shortages that directly affect the mobility of Russian armed forces. An army running short on fuel cannot counterattack effectively. This is a systemic pressure that complements tactical successes on the front.

Consequences for the Russian war effort

The recourse to rear-area units also reveals a planning problem for Russia. Moscow anticipated a short war in 2022, with reserves scaled accordingly. Four years later, the structure of Russian forces bears the scars of that initial miscalculation. Losses have not been compensated by equivalent formations — they have been compensated by hastily trained recruits and, now, by non-combat personnel rushed to the front line.

This situation has implications for the months ahead. If Russia can no longer reconstitute its combat forces at a sufficient pace, Ukrainian advances at Borova and Kostyantynivka could signal a deeper reversal in front-line dynamics — not necessarily a sweeping counteroffensive, but a gradual and inexorable degradation of the Russian posture.

Western support as an accelerator

The equipment that makes the difference

Behind Ukraine's battlefield advances lie years of Western military aid that have transformed the capabilities of the Ukrainian army. Leopard tanks, HIMARS systems, reconnaissance drones, anti-tank missiles, and air defense systems have progressively given Ukrainian forces a local technological advantage on most axes where they choose to attack.

In June 2026, that support continues. Belgium announced the delivery of 7 additional F-16s. Germany is negotiating deliveries of Patriot missiles. The United States, despite the ambiguities of the Trump administration, maintains an aid flow that, even reduced, remains crucial. Ukraine is not alone — and that is what explains its ability to attack on two fronts simultaneously.

Training as a force multiplier

Beyond equipment, the training provided by Western allies has transformed the Ukrainian army at its core. Ukrainian officers have trained at American, British, German, and French military schools. They have learned NATO doctrine, operational planning, combined-arms coordination. These skills are visible today on the terrain of Borova and Kostyantynivka.

This is an investment whose dividends are measured in meters gained and Russian reserve units consumed. Every Ukrainian officer trained in the West is a force multiplier on the ground. And Russia, with its rigid hierarchical system inherited from the Soviet era, has no equivalent to offer.

The information war around the advances

Russian propaganda versus geolocated facts

Every Ukrainian advance is immediately contested by the Russian propaganda machine. Pro-Kremlin Telegram channels minimize, relativize, and speak of "tactical maneuvers" rather than retreats. The Russian Ministry of Defense produces boilerplate communiqués about "positions adjusted according to plan."

But geolocated images do not lie. When an open-source analyst can overlay a satellite image from June 4 with one from June 8 and show the shift in the line of contact, propaganda becomes powerless. This is one of the great differences between this war and previous conflicts: the truth ultimately emerges, even if delayed.

The role of independent Ukrainian media

Outlets like the Kyiv Independent, Ukrinform, United24 Media, and Euromaidan Press play a crucial role in disseminating verified information about the state of the front. They operate under wartime conditions, with the legitimate operational security constraints that national security demands, yet they maintain remarkable journalistic standards in that context.

These outlets are the first to report Ukrainian advances, often with maps, images, and clearly identified sources. Their work complements that of open-source analysts and the ISW to build as accurate a picture of the conflict as possible despite the fog of war.

The Donetsk front in its entirety

Pokrovsk, Kurakhove, Vuhledar: the bigger picture

The advances at Kostyantynivka-Druzhkivka are part of a broader Donetsk front that remains bitterly contested. To the west, Russian pressure on Pokrovsk — a critical logistics hub — holds, with dozens of daily assaults. In the Kurakhove sector, Russian forces recorded limited advances in May and June before being slowed by Ukrainian counterattacks.

The overall picture shows a front line that holds, deforming locally but not breaking. The Ukrainian advances at Kostyantynivka add further pressure on a Russian command already in difficulty. Every sector under strain is a sector that cannot be reinforced elsewhere.

Logistics as the sinew of war

In modern warfare, logistics is often decisive. An army's ability to supply its troops with ammunition, fuel, and materiel directly conditions its ability to attack or hold a defense. Ukrainian strikes on Russian logistics depots, railway bridges, and road junctions in rear areas have progressively degraded that capability.

In Donetsk, Russian supply difficulties translate into artillery ammunition shortages — a phenomenon documented by several independent sources. Artillery that fires less hard or less accurately means Ukrainian infantry can advance a little more easily. The causal chain runs from the Ukrainian deep strike all the way to the advance at Kostyantynivka.

Russian losses in both sectors

The price of combat for Russia

The fighting at Borova and Kostyantynivka-Druzhkivka has an enormous human and material cost for both sides, but particularly for Russia, which is launching costly assaults with troops of diminishing quality. According to the Ukrainian General Staff, Russian losses in June 2026 regularly exceed 1,200 soldiers per day across all fronts.

In the Borova and Kostyantynivka sectors, the counterattack operations launched in response to Ukrainian advances generate additional Russian losses. Attacking prepared defensive positions generally costs three times the losses of defending. Ukrainians know this and exploit every Russian recovery attempt to inflict maximum damage.

Materiel destroyed: armor, artillery, drones

Beyond human losses, the fighting of June 2026 in both sectors also consumed Russian materiel in significant quantities. T-72 and T-80 tanks, armored personnel carriers, artillery systems, and above all massive quantities of Shahed loitering munitions — all of this represents capital that Russia struggles to reconstitute as fast as it is being destroyed.

The organization Oryx, which documents equipment destruction on the basis of visual evidence, counts thousands of destroyed Russian heavy weapons since the start of the conflict. The pace of destruction in June 2026 reflects the intensity of fighting in the active sectors. And every tank destroyed is a tank Russia cannot send to the next front.

The international reaction to Ukrainian advances

The West observes and adjusts its support

The Ukrainian advances at Borova and Kostyantynivka, confirmed by the ISW on June 9, 2026, were received with satisfaction in Western capitals that support Ukraine. In Washington, Berlin, Paris, and London, these reports are integrated into the ongoing assessment of the effectiveness of the military support provided.

In practice, battlefield advances serve as an argument for continuing — or even intensifying — support. They demonstrate that Western aid produces concrete results, which is indispensable for maintaining political support in democracies where public opinion must be convinced that every euro or dollar spent in Ukraine is well invested.

Pressure on hesitant allies

These successes also create pressure on allies that still hesitate to provide certain types of equipment — long-range missiles, additional aircraft, cluster munitions. When Ukraine proves it uses effectively what it is given, the "red line" argument becomes increasingly difficult to maintain for wary governments.

Hungary under Viktor Orbán, the most accommodating partner toward Moscow within NATO, finds itself increasingly isolated in its obstruction. Ukrainian advances strengthen those within the alliance who push for unconditional support — through to victory.

Outlook: what can we expect in the weeks ahead

Will pressure intensify on these two axes?

Can the advances documented between June 4 and 14, 2026 at Borova and Kostyantynivka-Druzhkivka lead to a broader progression? That is the question no honest analyst can answer with certainty. The war in Ukraine has accustomed its observers to surprises in both directions: breakthroughs that consolidate, but also Russian counteroffensives that recover Ukrainian gains.

What can be said is that the conditions for sustained pressure appear to be in place: exhausted Russian troops replaced by undertrained units, degraded logistical lines, a Ukrainian air defense holding thanks to Patriot missile deliveries, and Ukrainian forces that have regained confidence after the advances of June 2026.

The role of deep strikes in front-line dynamics

Ukraine's deep-strike campaign — against refineries, ammunition depots, command centers inside Russia — plays a supporting role in ground advances. By degrading Russian logistics capacity, these strikes reduce enemy fire density in the sectors where Ukraine is trying to advance. This is total, multi-domain warfare, involving action 2,000 km deep to create effects at Borova.

If this dynamic holds — Ukrainian deep strikes combined with tactical advances — the weeks ahead could bring further confirmation of progress. But caution is warranted: Russia has shown a capacity to absorb considerable losses and maintain military pressure that defies all predictions of collapse. This conflict is not yet over.

The psychological dimension: morale on both sides

The effect of advances on Ukrainian morale

Victories, even modest ones, carry psychological value that exceeds their tactical significance. When Ukrainian soldiers at Borova or Kostyantynivka advance a few hundred meters and retake a village, an entire chain of command draws renewed energy from it. After months of defense under pressure, offensive action restores the sense of initiative — one of the most precious factors in a war of attrition.

For the Ukrainian population, these advances confirmed by the ISW are also a signal of hope. In a country where sirens sound daily and Russian strikes hit cities, knowing that its soldiers are advancing on the Kharkiv and Donetsk fronts keeps alive the conviction that this war can be won. Civilian resilience in Ukraine is inseparable from military successes.

The demoralizing effect on Russian forces

Conversely, for Russian soldiers confronting Ukrainian advances, the situation is psychologically grinding. Being replaced by rear-area units, watching positions fall despite orders to hold at all costs, receiving undertrained reinforcements rather than seasoned troops — all of this erodes fighter morale. The desertions, self-inflicted injuries, and surrenders documented in June 2026 attest to this deep exhaustion.

Russia can compensate through coercion — military discipline, fear of firing squads, family pressures. But coercion does not replace morale. An army held together by fear alone is an army that, sooner or later, collapses. The question is when.

Conclusion: Two axes, one strategic message

The significance of the June 9 advances

The ISW's confirmations on June 9, 2026 of Ukrainian advances at Borova and Kostyantynivka-Druzhkivka are not mere front-line bulletins. They send a clear strategic message: the Ukrainian army, despite more than four years of war and considerable losses, retains the ability to attack on multiple axes simultaneously. This is what is called freedom of action — and having it in June 2026, against a Russia that is committing its rear reserves, is a remarkable achievement.

The geolocated images, enemy confirmations, and independent assessments all converge on the same conclusion: the front-line dynamic, while fragile and reversible, now favors Ukraine on these two key sectors. This is a precious asset in the diplomatic negotiation that will sooner or later have to complement military successes.

What this says about Ukraine in 2026

In June 2026, Ukraine is a country that has turned war into a school. It has learned to strike deep, advance carefully, exploit the enemy's weaknesses while preserving its own forces. The advances at Borova and Kostyantynivka illustrate this operational maturity. They also illustrate the tenacity of a people that refuses capitulation, despite the relentless pressure of a Russia hoping for Ukrainian exhaustion before its own.

That Russian bet is being lost. Not in a single heroic act, but millimeter by millimeter, geolocated image by geolocated image, recaptured village by recaptured village. This is how wars of attrition are sometimes won.

Columnist's transparency note

Who I am and my acknowledged biases

I am Maxime Marquette, a columnist and analyst specializing in armed conflicts and geopolitics. I am pro-Ukrainian — not blindly, but because the facts seem clear to me: Ukraine is the victim of an aggression that violates international law, and Zelensky is a head of state who chose to defend his people rather than flee. I do not claim neutrality; I claim honesty. My sources are cited, my conclusions are my own.

I acknowledge that certain information about this front — notably precise positions and troop numbers — cannot be independently verified for operational reasons. I rely on the ISW, recognized Ukrainian media, and open-source analyses. Where genuine uncertainty exists, I flag it.

What I do not know

I do not know the exact number of soldiers involved in these operations, nor the precise losses on each side. The figures published by the Ukrainian General Staff are estimates — honest ones, but estimates nonetheless. I also do not know what the trajectory of the coming weeks will be on these two axes. War has too often confounded predictions for me to formulate one with confidence.

What I do know is that the documented facts — geolocated advances, enemy confirmation, commitment of Russian rear reserves — point in the direction I have described. I stand behind this report under my byline and my responsibility.
