1. Introduction: Donbas as the Epicenter of Fighting
As the Russia-Ukraine war entered its fourth year in February 2025, the Donbas region -- encompassing Donetsk and Luhansk oblasts -- remained the principal theater of ground combat. While the conflict has seen dramatic episodes elsewhere, from the liberation of Kherson to the audacious Ukrainian incursion into Kursk Oblast, it is in the scarred industrial towns and rolling steppe of Donbas that the war's trajectory is being determined through grinding, attritional combat.
Throughout 2024 and into 2025, Russia committed the bulk of its offensive capability to Donbas, launching daily waves of infantry assaults supported by glide bombs, artillery, and drones. The objective: to seize the entirety of Donetsk Oblast and complete the capture of the territories Russia illegally annexed in September 2022. Ukraine, facing manpower constraints and ammunition shortfalls, has adopted a strategy of elastic defense, trading space for time while inflicting maximum casualties on the attacking force.
Key Context
The Donbas conflict did not begin in 2022. Russia-backed separatists seized parts of Donetsk and Luhansk oblasts in 2014, establishing the so-called "people's republics." The full-scale invasion of February 2022 represented an escalation of a war that had already raged for eight years along the line of contact.
The situation in early 2025 presents a paradox. Russia is advancing, capturing village after village, and creeping toward major Ukrainian logistics hubs. Yet this advance comes at staggering cost: an estimated 800-1,200 Russian casualties per day across the Donbas front alone, according to Ukrainian General Staff data and Western intelligence assessments. The question that dominates military analysis is whether Russia can sustain this rate of attrition long enough to achieve its objectives, or whether the losses will eventually force a culmination.
2. Geographic Overview: Key Sectors and Axes of Advance
The Donbas front stretches approximately 250 kilometers from the Kupyansk sector in the north to the now-fallen city of Vuhledar in the south. Within this vast area, several distinct operational sectors have emerged, each with its own characteristics, terrain challenges, and strategic significance. Understanding the geography is essential to analyzing the dynamics of the fighting.
Pokrovsk Direction
The most strategically significant axis, targeting the railway junction city of Pokrovsk. Russian forces advanced from the east following the fall of Avdiivka and Selydove, pushing through open terrain toward the city's outskirts. As of early 2025, the front line lies approximately 5-10 km from the city center.
Critical ThreatChasiv Yar
A hilltop city overlooking the approaches to Kostiantynivka and the Kramatorsk-Sloviansk agglomeration. The Siverskyi Donets-Donbas canal provides a natural defensive barrier. Fighting has centered on the eastern neighborhoods and the canal crossing points.
Heavy FightingToretsk
An urban area northeast of Pokrovsk where Russian forces penetrated the city outskirts in summer 2024. Street-by-street fighting has continued for months, with both sides suffering significant casualties in close-quarters combat among apartment blocks and industrial structures.
Urban CombatKurakhove Direction
Following the capture of Kurakhove in late 2024, Russian forces pushed westward toward the administrative boundary of Donetsk Oblast. This sector saw some of the fastest Russian advances in the second half of 2024, aided by relatively flat terrain and the collapse of Ukrainian defenses around Vuhledar.
Active OffensiveKupyansk-Svatove-Kreminna
The northern Donbas front, where Russian forces have attempted to cross the Oskil River and recapture Kupyansk. This sector has been relatively static compared to the southern axes, with dense forest terrain favoring defense.
Probing AttacksSiversk
A secondary axis between Chasiv Yar and Kreminna, where Russian forces probe Ukrainian positions along the Zherebets River. The fighting here is less intense but ties down significant Ukrainian forces that cannot be redeployed to more critical sectors.
PositionalThe Urban-Industrial Landscape
Donbas is characterized by a dense network of mining towns and industrial cities, many dating to the Soviet era. These urban areas -- with their concrete apartment blocks, factory complexes, and underground mine shafts -- create a defensive nightmare for attackers and a fortress-like environment for defenders. The pattern of the war has been consistent: Russia expends enormous resources to capture one town, only to face the next fortified settlement a few kilometers further west.
The terrain between urban centers consists of rolling steppe, agricultural fields, and tree lines that have been transformed into no-man's-land by months of bombardment. Craters, burned-out vehicles, collapsed trenches, and the wreckage of downed drones litter the landscape. The once-productive farmland of Donetsk Oblast has become one of the most heavily mined and contested battlefields on Earth.
3. Russian Offensive Operations: Meat Assaults and Gradual Gains
Russia's approach to the Donbas campaign in 2025 is defined by a single, brutal doctrine: attritional pressure across the entire front, sustained indefinitely through waves of infantry assaults. The tactical pattern, colloquially known as "meat assaults" (myasnyye shturmy), has become the signature of the Russian war effort and represents a departure from conventional military doctrine that has shocked Western analysts.
The Anatomy of a Meat Assault
A typical Russian assault in Donbas follows a grim, predictable pattern. Small groups of 5-10 soldiers, often from Storm-Z penal units, newly mobilized troops, or contracted soldiers with minimal training, are sent toward Ukrainian positions. Their mission is to probe defenses, draw fire, and identify Ukrainian fighting positions. The first wave rarely survives. Follow-up waves attempt to exploit any gaps or weak points revealed by the losses of their predecessors.
Daily Assault Intensity
The Ukrainian General Staff reports an average of 150-200 combat clashes per day across the entire front, with 60-70% occurring in the Donbas sector. On particularly intense days, the number exceeds 200 clashes. Each "clash" can involve multiple assault waves and last several hours. This level of sustained offensive action is unprecedented in modern European warfare.
The Role of Glide Bombs (KABs)
Russia's air force has become a critical enabler of ground offensives through the mass employment of glide bombs -- Soviet-era FAB-250, FAB-500, and FAB-1500 general-purpose bombs fitted with UMPK guidance kits. Launched from Su-34 strike aircraft operating 40-70 km behind the front line (beyond the range of most Ukrainian air defenses), these bombs deliver devastating explosive power that can obliterate fortified positions, collapse buildings, and create massive craters that reshape the terrain.
In 2025, Russia is estimated to employ 80-120 glide bombs per day across the Donbas front. The psychological and physical impact of these weapons cannot be overstated: a single FAB-1500 (containing 1,500 kg of explosives) can demolish an entire apartment block, while the persistent threat forces Ukrainian troops to constantly rotate positions and limits the effectiveness of static fortifications.
Territorial Gains: Slow but Persistent
Russia's territorial gains in Donbas during 2024-2025, while modest by historical standards, represent the most sustained period of Russian advance since the early months of the war. The pace has averaged roughly 1-3 kilometers per week on the most active axes, with gains often measured in individual buildings, tree lines, or field sections.
4. Ukrainian Defensive Strategy: Elastic Defense and Attrition
Facing a numerically superior enemy with a significant advantage in artillery and aviation, Ukraine's Armed Forces (ZSU) have adopted a defensive posture in Donbas that prioritizes personnel preservation and attritional damage over rigid territorial defense. This approach, often described as "elastic defense," represents a pragmatic adaptation to the realities of the battlefield.
Principles of Ukrainian Defense in Donbas
- Attrition over territory: The primary objective is to inflict maximum casualties on Russian forces while minimizing Ukrainian losses. Defending every meter of ground is secondary to bleeding the attacker.
- Elastic withdrawal: When positions become untenable due to bombardment, flanking, or ammunition shortages, units withdraw to prepared fallback positions rather than fighting to the last man in doomed positions.
- Fire-centric defense: Rather than relying on trench lines held by infantry, Ukrainian defense emphasizes overlapping fields of fire from artillery, mortars, drones, and machine guns that create kill zones for advancing Russian infantry.
- Rotation and preservation: Units are rotated regularly to prevent exhaustion and maintain combat effectiveness. Fresh reserves replace depleted units before they reach breaking point.
- Counterattack at the tactical level: Ukrainian forces frequently launch small-scale counterattacks to retake lost positions, prevent Russian consolidation, and maintain initiative at the tactical level even while ceding ground operationally.
The Syrskyi Doctrine
Commander-in-Chief Oleksandr Syrskyi, who replaced Valerii Zaluzhnyi in February 2024, is widely associated with the shift toward elastic defense. His approach emphasizes that Ukrainian commanders should prioritize the lives of soldiers over arbitrary geographic objectives, withdrawing from untenable positions when necessary rather than absorbing catastrophic losses. This doctrine was first demonstrated in the ordered withdrawal from Avdiivka and has since defined the ZSU's approach to the entire Donbas front.
Challenges Facing Ukrainian Defenders
The elastic defense strategy, while rational, faces significant challenges. Constant withdrawal, even when tactically sound, erodes morale among both soldiers and the civilian population. Each lost village represents homes, memories, and national territory conceded to the enemy. The psychological burden of a fighting retreat is considerable, and maintaining unit cohesion under these conditions requires exceptional leadership at every level.
Furthermore, the strategy depends on having prepared fallback positions, adequate supplies to maintain the attrition balance, and sufficient manpower to rotate units. In 2025, all three of these prerequisites are under strain, creating a situation where the elastic defense risks becoming a disorganized retreat if any single factor collapses.
5. Force Ratio and Manpower Situation
The manpower situation is perhaps the most critical factor shaping the Donbas campaign in 2025. Both sides face significant personnel challenges, but the nature and scale of these challenges differ dramatically.
Russian Manpower
Russia has sustained its offensive through a combination of voluntary recruitment (incentivized by signing bonuses reportedly reaching 2-3 million rubles), covert mobilization through regional recruitment drives, and the incorporation of foreign fighters, including North Korean soldiers deployed to the Kursk front beginning in late 2024. Russia is estimated to recruit 25,000-30,000 new soldiers per month, roughly matching its estimated monthly casualty rate and allowing it to maintain offensive pressure without a formal second mobilization.
Ukrainian Manpower
Ukraine faces a more acute manpower challenge. Despite the mobilization law passed in April 2024, which lowered the conscription age from 27 to 25 and tightened exemptions, recruitment has struggled to keep pace with losses and the need to rotate exhausted frontline units. Ukraine's smaller population base (approximately 37 million before the war, reduced by refugees and occupation) limits its ability to match Russian numbers through sheer volume.
The quality gap remains in Ukraine's favor. Ukrainian soldiers generally receive better training (including programs conducted by NATO allies), fight with higher motivation (defending their homeland), and operate with greater tactical initiative. However, quantity has a quality of its own, as Stalin reportedly quipped, and Russia's willingness to absorb massive casualties while maintaining pressure is testing the limits of Ukrainian manpower.
The Rotation Crisis
Perhaps the most severe manifestation of Ukraine's manpower challenge is the inability to adequately rotate units. Some Ukrainian brigades have been on the front line for months without relief, leading to physical and psychological exhaustion, declining combat effectiveness, and increasing disciplinary issues. The problem is circular: insufficient reserves prevent rotation, exhaustion leads to casualties, casualties further deplete the available manpower, making rotation even harder.
| Factor | Russia | Ukraine |
|---|---|---|
| Total population base | ~144 million | ~37 million (pre-war) |
| Troops in theater (est.) | ~600,000 | ~300,000-400,000 |
| Monthly recruitment | ~25,000-30,000 | ~15,000-20,000 |
| Average training period | 2-4 weeks (often less) | 4-8 weeks (basic) + NATO programs |
| Motivation factor | Financial incentives, coercion | Defense of homeland, national survival |
| Key vulnerability | Quality, morale, training | Quantity, rotation, exhaustion |
6. Key Battles in Donbas (2024-2025)
The Pokrovsk Direction
Pokrovsk has been the primary focus of Russian offensive operations since the fall of Avdiivka in February 2024. The city, with a pre-war population of approximately 60,000, serves as the central railway junction and logistics hub for the entire Ukrainian front in Donetsk Oblast. Its fall would sever the primary supply lines to multiple sectors and potentially force a cascading withdrawal across the front.
Russian forces advanced toward Pokrovsk along the M30 highway from Avdiivka, pushing through a string of villages and small towns. The advance was initially rapid by the standards of the war, with Russian forces covering 30+ km in the first six months. However, the pace slowed significantly as Ukrainian forces established increasingly robust defensive positions and the terrain became more difficult to navigate as settlements grew denser around the city.
By early 2025, the front line stabilized approximately 5-10 km east and southeast of Pokrovsk. Ukrainian forces constructed multiple defensive lines, including trenches, bunker systems, and anti-vehicle obstacles, transforming the approaches to the city into a layered defensive zone. The Russian advance, while continuing, slowed to meters per day in many sectors.
The Battle for Chasiv Yar
Chasiv Yar occupies a dominant hilltop position overlooking the surrounding terrain, making it a natural fortress. The city's capture would give Russian forces a commanding view of the routes toward Kostiantynivka and, ultimately, the twin cities of Kramatorsk and Sloviansk -- the largest Ukrainian-held population centers in Donetsk Oblast.
The fighting at Chasiv Yar has been characterized by the canal barrier. The Siverskyi Donets-Donbas canal, which runs through the eastern portion of the city, acts as a significant obstacle to Russian advances. Ukrainian forces have used the canal as a defensive line, destroying bridges and covering crossing points with direct fire. Russian attempts to cross the canal have been repeatedly repulsed with heavy losses, though fighting continues in the eastern micro-districts.
New York (Niu-York)
The small town of New York (Ukrainian: Niu-York), named by Welsh settlers in the 19th century, became the subject of intense fighting in mid-2024. Located north of Toretsk, the town's capture by Russian forces in late 2024 was strategically significant as it opened an approach to Toretsk from the north and demonstrated Russia's ability to advance even in well-fortified urban terrain.
Selydove
Selydove, a town of approximately 20,000 people southwest of Pokrovsk, fell to Russian forces in late 2024 after weeks of encirclement and urban combat. The loss of Selydove exposed the southern approaches to Pokrovsk and complicated Ukrainian logistics in the sector. The battle illustrated the pattern of the Donbas campaign: Russian forces gradually encircled the town, cut supply routes, and forced a Ukrainian withdrawal under pressure.
The Pattern of Town Capture
Russian operations in Donbas follow a remarkably consistent pattern: (1) approach from multiple directions using infantry, (2) achieve fire control over supply routes using artillery and drones, (3) gradually encircle the settlement, (4) grind through urban defenses using infantry, glide bombs, and thermobaric weapons, (5) force Ukrainian withdrawal when holding becomes untenable. This pattern has been replicated at Avdiivka, Marinka, Vuhledar, Selydove, Kurakhove, and New York.
7. Artillery and Ammunition: The Shell Balance
Artillery remains the primary killer on the Donbas battlefield, responsible for an estimated 60-70% of all casualties despite the growing prominence of drones. The ammunition balance between Russia and Ukraine is one of the most critical factors determining the course of the war.
Russian Artillery Advantage
Russia fires an estimated 10,000-15,000 artillery rounds per day across the Donbas front, drawing on a combination of domestic production (ramped up to an estimated 3 million rounds per year by 2025), Soviet-era stockpiles (depleting but still substantial), and imported ammunition from North Korea (an estimated 5-8 million rounds delivered since 2023) and Iran.
This volume of fire, while not approaching the peak rates of 2022 (when Russia fired up to 60,000 rounds per day on the most intense days), provides a persistent bombardment that degrades Ukrainian positions, suppresses movement, and attrites personnel. Russia employs a mix of 152mm howitzers, 122mm MLRS, and 120mm mortars, supplemented by thermobaric rocket launchers (TOS-1 Solntsepyok) for particular high-value targets.
Ukrainian Shell Hunger
Ukraine fires approximately 3,000-5,000 artillery rounds per day, a figure that has improved from the crisis lows of early 2024 (when some sectors were limited to a few hundred rounds per day) thanks to the Czech ammunition initiative, increased European production, and resumed US deliveries. However, the 3:1 to 5:1 disparity remains a fundamental challenge.
The Quality Versus Quantity Trade-Off
Ukraine partially compensates for its quantitative disadvantage through precision. Western-supplied systems like the M777 howitzer, PzH 2000, CAESAR, Krab, and AS-90 offer greater accuracy than most Russian systems, and the availability of GPS-guided Excalibur rounds (though in limited numbers) allows Ukrainian gunners to achieve first-round hits on high-value targets. Furthermore, Ukraine has increasingly substituted artillery fire with cheaper, more precise FPV drone strikes, partially offsetting the shell imbalance.
Russia, conversely, relies on volume of fire rather than precision, blanket-bombing grid squares and using area-fire techniques that consume enormous quantities of ammunition but ensure that some percentage of rounds find their targets. The inefficiency of this approach is offset by Russia's ability to produce and procure ammunition in quantities that Ukraine cannot match.
8. The FPV Drone Revolution in Donbas Fighting
If there is one weapon system that defines the Donbas campaign in 2025, it is the First Person View (FPV) drone. These small, inexpensive, operator-guided munitions have transformed the tactical landscape of the war, creating a battlefield environment unlike any seen in previous conflicts.
Scale of Drone Operations
Both sides deploy thousands of FPV drones daily across the Donbas front. Ukraine is estimated to produce 100,000-150,000 FPV drones per month, while Russia has rapidly scaled its own production to comparable levels. The sheer volume means that virtually every vehicle movement, troop concentration, or supply run within several kilometers of the front line is at risk of drone attack.
The Economics of Drone Warfare
An FPV drone costs approximately $400-$500 to produce, while the targets it destroys -- armored vehicles, artillery pieces, command posts, ammunition dumps -- can be worth millions of dollars. This asymmetry has fundamentally altered the economics of warfare. A single $500 drone can destroy a $3 million infantry fighting vehicle, a $5 million tank, or a $10 million self-propelled howitzer. The cost-exchange ratio overwhelmingly favors the drone operator.
Impact on Ground Operations
FPV drones have made the Donbas battlefield extraordinarily lethal for anyone moving in the open. Armored columns are now rarely employed because vehicles concentrated in groups present irresistible targets. Instead, vehicles move individually, at night, along routes screened by electronic warfare. Infantry must advance in small groups, using cover and terrain to avoid detection by the ever-present surveillance drones that loiter overhead, directing FPV strikes.
The drone threat has also changed the nature of fortifications. Traditional trenches with straight sections are vulnerable to drones flying along the trench line. Defenders have adapted by constructing zigzag patterns, overhead cover, and drone nets, while both sides employ electronic warfare systems to jam drone control signals in their defensive zones.
Drone Types in Use
- FPV kamikaze drones: The workhorse of the battlefield, guided by an operator wearing FPV goggles. Carries a warhead (typically an RPG round or modified mortar round) and flies into the target at speed. Effective range: 5-15 km.
- Reconnaissance quadcopters: Used for surveillance, target acquisition, and artillery correction. Both DJI Mavic series and custom-built models are ubiquitous.
- Heavy bomber drones: Modified civilian drones (like the DJI Matrice series) capable of dropping grenades, mortar rounds, or anti-tank munitions onto positions below. Effective for trench warfare.
- Fiber-optic FPV drones: An emerging technology that transmits control signals through a trailing fiber-optic cable, making the drone immune to electronic warfare jamming. Both sides are racing to deploy these in quantity.
- Long-range strike drones: Ukrainian Bober and Liutyi drones, and Russian Lancet loitering munitions, used for strikes on high-value targets 20-50+ km behind the front line.
Electronic Warfare: The Invisible Battle
Alongside the drone revolution has come an equally significant expansion of electronic warfare (EW). Both sides deploy jammers designed to disrupt drone control signals and GPS navigation. The EW battle is a constant cat-and-mouse game: operators switch frequencies, adopt new protocols, and develop jam-resistant technologies, while EW specialists develop new countermeasures. The density of EW equipment along the Donbas front is likely the highest anywhere in the world, creating a complex electromagnetic environment that shapes every tactical decision.
9. Fortification and Engineering: Trenches, Bunkers, and Dragon's Teeth
The Donbas campaign has witnessed a return to engineering-intensive warfare not seen since the World Wars. Both sides have invested heavily in fortifications, transforming the landscape into a layered system of defensive positions that would be recognizable to veterans of Verdun or Kursk.
Ukrainian Fortification Strategy
Ukraine has constructed multiple lines of defense behind the current front line, creating a defense-in-depth system designed to slow and attrit Russian advances even if forward positions are lost. These fortification lines typically consist of:
- Forward trenches and fighting positions: The first line of defense, manned by infantry with direct fire weapons, observation equipment, and drone operators.
- Strongpoints and bunkers: Reinforced concrete positions, often using precast sections, that can withstand all but direct hits from large-caliber weapons or glide bombs.
- Anti-vehicle obstacles: Lines of "Dragon's Teeth" (concrete anti-tank pyramids), anti-tank ditches, and minefields designed to channel and slow armored movement.
- Artillery and mortar positions: Pre-surveyed firing positions with prepared ammunition storage, connected to forward observers via secure communications.
- Fallback lines: Secondary and tertiary defensive positions prepared in advance, allowing orderly withdrawal without loss of defensive coherence.
The Dragon's Teeth Controversy
In 2024, a major scandal erupted in Ukraine over the quality of fortifications constructed by civilian contractors. In some sectors, Dragon's Teeth anti-tank obstacles were poorly constructed, trenches were dug in the wrong locations, and bunkers lacked the specified reinforcement. The controversy led to investigations, personnel changes, and increased military oversight of fortification construction. By 2025, the quality of new fortifications has reportedly improved, though the episode highlighted the challenges of rapidly constructing defensive works under wartime conditions.
Lessons from World War I
Military historians have noted striking parallels between the Donbas front and World War I trench warfare: static front lines, massive artillery bombardments, high casualties for minimal territorial gains, and the dominance of defensive firepower over offensive maneuver. The key difference is technology -- drones and precision-guided munitions have replaced machine guns as the primary impediment to movement, and electronic warfare has replaced wire-cutting as a prerequisite for attacks. But the fundamental dynamic of attritional positional warfare remains eerily similar a century later.
Russian Engineering
Russian forces also construct fortifications, particularly in areas they have recently captured. These positions tend to be less elaborate than Ukrainian defensive works, reflecting Russia's offensive posture and the difficulty of building fortifications under constant drone observation and artillery fire. Russian engineering efforts focus on creating fighting positions that can serve as springboards for the next assault, with communication trenches connecting forward positions to rear areas for resupply and casualty evacuation.
10. Civilian Situation: Evacuations and Destroyed Cities
The civilian cost of the Donbas campaign is staggering and often underreported in coverage focused on military operations. The cities and towns of Donetsk Oblast -- once home to vibrant communities built around mining, industry, and agriculture -- have been systematically reduced to ruins.
Evacuations
The Ukrainian government has conducted mandatory evacuations from towns and cities in the path of the Russian advance. These operations, while saving countless lives, are logistically complex and emotionally devastating for residents forced to abandon their homes, often with only a few hours' notice and minimal possessions.
As of early 2025, the following cities and towns have been partially or fully evacuated in the Donbas sector:
Pokrovsk
Mandatory evacuation ordered for families with children. Pre-war population: ~60,000. Estimated remaining: 10,000-15,000, primarily elderly and people refusing to leave.
Chasiv Yar
Largely evacuated. Pre-war population: ~12,000. Only a few hundred civilians remain, sheltering in basements under constant bombardment.
Toretsk
Evacuation ongoing amidst active urban combat. Pre-war population: ~30,000. An estimated 1,000-2,000 remain, unable or unwilling to leave.
Kostiantynivka
Under frequent missile and glide bomb attacks. Pre-war population: ~70,000. Significant civilian population remains as the city is further from the front line but still vulnerable.
Destroyed Urban Landscape
Cities that have been at the center of fighting -- Bakhmut, Avdiivka, Marinka, Vuhledar, and now Toretsk -- have been almost completely destroyed. Satellite imagery shows urban areas reduced to rubble, with scarcely a structure left intact. The scale of destruction is comparable to the worst urban fighting of World War II.
Marinka, a small city that was on the front line since 2014, was declared captured by Russia in late 2023 after being reduced to a field of rubble. Bakhmut, once a city of 70,000 people, is essentially obliterated. Avdiivka's industrial district, including the massive coke plant, is a post-apocalyptic ruin. These destroyed cities serve as grim monuments to the brutality of the Donbas campaign and a preview of what may await other urban centers if the fighting continues.
Human Cost
The UN estimates that over 10,000 civilians have been killed in the conflict since February 2022, with many more deaths unverified in occupied territories. In Donbas specifically, the daily reality for remaining civilians includes constant shelling, lack of running water, intermittent electricity, limited medical care, and the psychological trauma of living under bombardment for months or years. Volunteer organizations and Ukrainian emergency services perform dangerous evacuation runs under fire, often sustaining casualties themselves.
11. Terrain and Weather Factors
The physical environment of Donbas profoundly shapes the fighting, creating seasonal rhythms that influence the tempo and character of operations.
Terrain Characteristics
The Donbas landscape is predominantly flat to gently rolling steppe, with elevations rarely exceeding 300 meters above sea level. The terrain is dissected by small rivers and ravines that can serve as obstacles to movement and anchor points for defense. Key terrain features include:
- Elevation advantages: Cities like Chasiv Yar sit on relative high ground, providing observation and fire advantages that make them natural defensive bastions. The "spine" of higher ground running through central Donetsk Oblast has been critical in Ukrainian defense planning.
- River and canal barriers: The Siverskyi Donets River in the north and the Siverskyi Donets-Donbas canal near Chasiv Yar provide natural obstacles. Even small streams and irrigation channels can impede vehicle movement, particularly during wet seasons.
- Tree lines and forest belts: Strips of trees, originally planted as windbreaks for agricultural fields, provide concealment for troop movement and defensive positions. These have become fiercely contested terrain features, as they represent the only cover in otherwise open terrain.
- Urban areas: The dense network of towns creates a series of "fortresses" that must be taken one by one, dramatically slowing any attacker's progress.
- Mining infrastructure: Coal mine slag heaps (terricons) create artificial hills that serve as observation points. Underground mine shafts and tunnels occasionally feature in tactical planning.
Seasonal Patterns
Weather cycles create distinct operational seasons in the Donbas campaign:
- Spring (rasputitsa): March through April brings the thaw, turning unpaved roads and fields into impassable mud. Vehicle movement is largely confined to paved roads, making ambush and mining easier for defenders. The spring mud season typically slows offensive operations significantly.
- Summer: Dry conditions allow cross-country movement but also create dust signatures that reveal vehicle positions to drones. Dense vegetation provides concealment but also limits observation. Summer 2024 saw some of the most intense fighting of the campaign.
- Autumn (second rasputitsa): October and November bring rain and another period of mud, again constraining vehicle movement. The transition period often sees a temporary reduction in operational tempo.
- Winter: Frozen ground restores vehicle mobility but exposes troop movements against snow-covered terrain. Cold weather adds a logistical burden (heating, cold-weather gear) and physical stress on soldiers. Recent winters in Donbas have been relatively mild, limiting the traditional "winter freeze" advantage for the attacker.
12. Russia's Strategic Goals: Full Oblast Control
Russia's stated war aims have evolved since February 2022, but in Donbas, the objective has remained consistent: the complete capture of Donetsk and Luhansk oblasts within their internationally recognized administrative boundaries. This goal was formalized by Russia's illegal annexation of these oblasts (along with Zaporizhzhia and Kherson oblasts) in September 2022, despite not controlling significant portions of the territory claimed.
The Donetsk Oblast Objective
Of the two Donbas oblasts, Donetsk presents the greater challenge. Luhansk Oblast is approximately 98% under Russian control, with only a small pocket around Bilohorivka remaining contested. Donetsk Oblast, however, is roughly 55% under Ukrainian control, including the major cities of Kramatorsk, Sloviansk, Kostiantynivka, Pokrovsk, and Druzhkivka.
Capturing these cities would require either a series of grinding urban battles (each potentially as costly as Bakhmut or Avdiivka) or a breakthrough that forces Ukrainian forces to withdraw from a wide area. Neither scenario appears imminent given current force ratios and the pace of advance, but Russia's long-term strategy appears to rely on attrition: gradually degrading Ukrainian defensive capacity until the dam breaks.
Strategic Implications of Pokrovsk
The capture of Pokrovsk would represent a potential strategic inflection point. As the primary logistics hub for the Donetsk front, its fall would force Ukraine to rely on alternative, longer supply routes, complicating the defense of the entire region. Russian planners may believe that taking Pokrovsk could trigger a cascading withdrawal from multiple sectors, accelerating the advance toward the administrative boundary.
The Kramatorsk-Sloviansk Question
Kramatorsk (pre-war population: ~150,000) and Sloviansk (pre-war population: ~100,000) represent the ultimate Russian objectives in Donetsk Oblast. These twin cities, the largest Ukrainian-held urban areas in Donbas, would be enormously difficult to capture. A battle for Kramatorsk could dwarf Bakhmut in scale and duration, potentially consuming Russian resources for a year or more. The prospect of such a battle likely factors into both sides' strategic calculations.
Putin's Political Calculus
For Vladimir Putin, the Donbas campaign serves both military and political purposes. Domestically, the gradual capture of territory -- however incremental -- can be presented as evidence of "progress" and "victory" to sustain public support for the war. The Kremlin's propaganda apparatus highlights each captured village while ignoring the catastrophic casualty figures. Internationally, continued advances put pressure on Western governments and publics who question whether Ukraine can ever reclaim lost territory, potentially weakening support for continued military aid.
13. Assessment: Who Is Winning the Donbas Campaign?
The question of who is "winning" in Donbas depends entirely on the metric used, and honest analysts acknowledge the complexity.
Arguments That Russia Is Winning
- Russia is gaining territory, albeit slowly, across most active sectors
- Key Ukrainian logistics hubs (Pokrovsk) are under direct threat
- The fall of Avdiivka, Vuhledar, Selydove, and Kurakhove in 2024 demonstrates an ability to overwhelm Ukrainian defenses
- Russia's ability to sustain recruitment is matching or exceeding its casualty rate, preventing force degradation
- The uncertainty of Western (particularly US) support under changing political conditions gives Russia a potential long-term advantage
Arguments That Ukraine Is Winning
- Russia is suffering disproportionate casualties (estimated 3:1 to 5:1 in many engagements), which is unsustainable over years
- The territorial gains, when measured against cost, represent a pyrrhic advance -- Russia is capturing ruins at the expense of its combat power
- Ukraine's elastic defense has maintained cohesive front lines and avoided the catastrophic breakthroughs Russia needs for a decisive victory
- Drone technology, in which Ukraine holds a qualitative edge, is partially offsetting Russia's advantages in artillery and manpower
- The morale and cohesion of Ukrainian forces, while strained, remains fundamentally higher than that of Russian troops
The Most Likely Trajectory
Most independent analysts assess the Donbas situation as a grinding attritional stalemate that slightly favors Russia in the near term (due to manpower and ammunition advantages) but remains uncertain in the medium to long term. The campaign is fundamentally a race between Russia's ability to advance before its losses become politically or militarily unsustainable, and Ukraine's ability to hold long enough for the attrition balance to shift in its favor through increased Western support, domestic production, and innovative tactics.
The Key Variables
The trajectory of the Donbas campaign will likely be determined by factors outside the immediate battlefield: the scale and consistency of Western military aid, the outcome of diplomatic efforts, the sustainability of Russian recruitment, the resilience of the Russian economy under sanctions, and the morale of both armies after years of grinding combat. In this sense, the Donbas campaign is not merely a military contest but a test of national endurance on both sides.
14. Frequently Asked Questions
Can Russia capture all of Donetsk Oblast in 2025?
At the current rate of advance (1-3 km per week on the most active axes), full capture of the remaining 55% of Donetsk Oblast would take years. Major cities like Kramatorsk and Sloviansk would require massive urban battles that could each last months. While Russia is making incremental gains, a rapid breakthrough is considered unlikely by most military analysts unless Ukrainian defensive capacity collapses due to manpower or ammunition shortages.
What are "meat assault" tactics?
Meat assaults (Russian: myasnyye shturmy) describe a Russian infantry tactic involving repeated waves of small assault groups (typically 5-10 soldiers) attacking fortified Ukrainian positions with minimal armored support and often inadequate artillery preparation. The attackers are frequently drawn from Storm-Z penal units, recently mobilized soldiers, or poorly trained contractees. Casualty rates among assault groups can reach 80-90%, but the tactic serves to exhaust Ukrainian ammunition, reveal defensive positions, and occasionally overwhelm defenders through sheer persistence. The term originates from Russian soldiers themselves, who refer to the attacks as "meat."
Why is Pokrovsk strategically important?
Pokrovsk is the most critical logistics node for the Ukrainian defense of Donetsk Oblast. The city sits at the junction of major road and railway routes that supply the entire front from Chasiv Yar in the north to the southern sectors. If Russia captures Pokrovsk, Ukrainian forces across a wide area would be forced to rely on longer, more vulnerable supply lines, potentially destabilizing the defense of the entire region. The city is also an important evacuation hub for civilians fleeing the combat zone.
How have FPV drones changed the fighting in Donbas?
FPV drones have become the single most impactful weapon innovation in the Donbas campaign. They account for more armored vehicle kills than anti-tank missiles, have made large-scale vehicle concentrations suicidal, and forced both sides to fundamentally redesign their tactical approaches. The cost ratio -- a $500 drone destroying a multi-million-dollar vehicle -- has altered the economics of warfare. Both sides now deploy thousands of FPV drones daily, creating an omnipresent lethal threat to anything that moves within several kilometers of the front line. This has led to the development of counter-drone technologies, electronic warfare systems, and new tactical doctrines that emphasize dispersal, concealment, and night movement.
What is the shell disparity between Russia and Ukraine?
Russia fires approximately 10,000-15,000 artillery rounds per day on the Donbas front, compared to Ukraine's 3,000-5,000 rounds. This 3:1 to 5:1 disparity has improved from the worst period in early 2024 (when it reached 7:1 or higher in some sectors) thanks to the Czech ammunition procurement initiative, increased European production, and resumed US deliveries. However, the gap remains significant. Russia draws on domestic production (approximately 3 million rounds per year), Soviet-era stockpiles, and North Korean imports. Ukraine depends primarily on Western supplies, supplemented by growing domestic production.
Who is winning the battle for Donbas?
This question has no simple answer and depends on the metric used. Russia is gaining territory, which by one measure constitutes success. However, the territorial gains come at catastrophic cost -- estimated at 800-1,200 casualties per day on the Donbas front alone -- and the captured territory consists largely of ruins with no economic or strategic value beyond the advance itself. Ukraine is inflicting disproportionate losses and maintaining defensive coherence, but is losing ground and facing its own manpower and supply challenges. Most analysts describe the situation as a grinding attritional contest that neither side is decisively winning, though Russia's larger manpower reserves give it a structural advantage if Western support for Ukraine does not remain consistent.
What role do North Korean soldiers play in the fighting?
Beginning in late 2024, North Korea deployed an estimated 10,000-12,000 soldiers to support Russian operations, primarily in the Kursk Oblast sector rather than directly in Donbas. However, their presence frees up Russian units for redeployment to the Donbas front. The North Korean soldiers have reportedly suffered significant casualties, and their effectiveness has been mixed, with language barriers, unfamiliarity with modern drone warfare, and differences in military doctrine limiting their combat value.
Could a ceasefire freeze the current lines in Donbas?
This is one of the most debated questions of 2025. A ceasefire along current lines would leave Russia in control of approximately 45% of Donetsk Oblast and 98% of Luhansk Oblast. Ukraine's position is that no ceasefire can be accepted that legitimizes Russian territorial conquest. Russia has shown no willingness to withdraw from occupied territories. Any diplomatic resolution would need to address the disposition of these territories, making the Donbas situation central to any peace negotiations.
