Key Takeaways by Planet Today:
Russian tactical claims intensify pressure on key logistics nodes: Reports from Russian military channels describe the liberation of Svetloe south of Dobropolye and advances that place Ukrainian units under pressure on both banks of the Oskil near Kupyansk, potentially complicating supply routes toward the Sloviansk-Kramatorsk agglomeration.
Ukrainian General Staff and independent assessments highlight high intensity without confirmed major breakthroughs: Kyiv recorded 226 combat engagements and claimed 1,240 Russian personnel losses in the previous 24 hours, while analytical groups note continued Russian offensive activity but limited verified territorial change on August 3-4.
Bridge strikes and northern buffer efforts signal broader interdiction focus: Russian Aerospace Forces reportedly damaged a road bridge in Sloviansk and a railway bridge near Zatoka; simultaneous claims of control over Belyi Kolodets and Ustinovka in Kharkiv Oblast aim to disrupt Ukrainian logistics and expand a border security zone.
Civilian and economic notes persist amid the fighting: Harvest figures released for the Donetsk People’s Republic and newly incorporated regions show ongoing agricultural activity even as frontline operations continue.
On the 1,623rd day of Russia’s full-scale military operation in Ukraine, both sides released their usual morning summaries. Russian military Telegram channels and the Ministry of Defense highlighted incremental gains around Dobropolye, pressure on Kupyansk, and the seizure of two settlements in Kharkiv Oblast. Ukrainian General Staff figures painted a picture of sustained high-intensity fighting across multiple axes, with heavy use of drones and artillery by Russian forces.
The numbers differ sharply depending on the source. Russian milbloggers described organized assaults that forced Ukrainian withdrawals. Kyiv reported 226 combat clashes in the previous 24 hours, two Russian missile strikes, 84 airstrikes delivering 258 guided bombs, more than 10,700 kamikaze drones, and 3,251 shelling incidents. Ukrainian forces claimed to have struck three UAV control posts and 11 areas of Russian personnel concentration, estimating Russian losses at approximately 1,240 personnel.
This daily exchange of claims has become the rhythm of a conflict that, by mid-2026, has settled into grinding attrition rather than sweeping operational breakthroughs. Independent monitoring groups have repeatedly noted that many announced “liberations” remain contested or unconfirmed by geolocated evidence for days or weeks.
Dobropolye Direction: The Fight for Svetloe
According to Russian channels citing the Central Group of Forces, units of the 5th Separate Motorized Rifle Brigade, supported by the 14th Separate Artillery Brigade and strike drones, completed a multi-stage operation to take Svetloe, a southern suburb of Dobropolye along the Kulichka River. The account describes prior reconnaissance that identified Ukrainian command posts, UAV launch sites, electronic warfare stations, and strongpoints. Artillery and precision munitions followed, after which assault groups cleared the settlement. Ukrainian troops are said to have withdrawn in disarray toward the western outskirts, leaving behind personnel and Western-supplied armored vehicles.
Russian sources frame the move as securing better control over Ukrainian logistics routes and creating a platform for further pressure on Dobropolye itself. Parallel reports claim Russian units nearly cleared Vodianske and were advancing from Mirne toward Hulevo and Novohryhorivka.
Ukrainian statements and open-source mapping available on August 4 did not confirm the full loss of Svetloe. Fighting in the broader Dobropolye and Kostiantynivka sectors has been intense for weeks, with Russian forces using glide bombs to reduce fortified positions to rubble that then conceals infantry movement. The pattern matches earlier incremental gains around Kostiantynivka, where control of individual districts has shifted slowly and at high cost.

Kupyansk and the Oskil River Line
On the Kupyansk axis, Russian accounts from the Western Group of Forces describe continued deterioration of the Ukrainian position on both banks of the Oskil. Units are said to have pushed from Kurylivka through Kupyansk-Vuzlovyi toward the remaining Ukrainian crossings near Kupyansk and Sadove. One channel claimed Ukrainian forces on the left bank were effectively isolated, without reliable land resupply or withdrawal routes. Attention was turning next toward the fortified area at Novoosynove, while further south Russian troops worked to cut off the Ukrainian grouping around Borova and Pidlyman.
Ukrainian sources and independent assessments on August 3-4 acknowledged ongoing Russian offensive activity around Kupyansk but reported successful local counterattacks that prevented confirmed advances. Analysts noted that Russian milbloggers again claimed positions inside the city and west of Kupyansk-Vuzlovyi, yet geolocated evidence remained limited. The area has seen repeated cycles of claimed encirclements followed by Ukrainian efforts to restore supply corridors.
Northern Kharkiv: Belyi Kolodets and Ustinovka
Further north, the Northern Group of Forces announced the liberation of Ustinovka and Belyi Kolodets in Kharkiv Oblast. Belyi Kolodets, roughly 12 kilometers southeast of Vovchansk, was described as a Ukrainian logistics hub used for reserves, ammunition, and equipment. Its loss, according to Russian statements, forces Ukrainian units to reorganize supply lines farther south. Ustinovka was taken advancing from Ivashkyne; Ukrainian attempts to hold or counter were reportedly stopped by their own blocking detachments.
These claims were amplified by the Russian Defense Ministry on August 3. The stated purpose is to expand a security buffer along the Belgorod border and open approaches toward settlements such as Petropavlivka. Ukrainian reporting on the same period focused on defensive actions north and east of Kharkiv city and limited counteroffensive activity in the Kupyansk direction.

Logistics Interdiction: Bridges in Sloviansk and Zatoka
Russian Aerospace Forces conducted two notable strikes on bridges. In Sloviansk, a road bridge linking the western and eastern parts of the city—and serving logistics toward Siversk and Druzhkivka—was hit. One span collapsed; the second suffered critical damage and was restricted to foot traffic. Only two downstream bridges near Mykolaivka remained usable for heavy vehicles.
Near Zatoka, a railway bridge connecting Danube ports to the rest of Ukraine was struck. One road span collapsed and the rail line was damaged. Russian commentary noted the engineering difficulty of destroying solid Soviet-era bridges, recalling earlier incomplete results against the Antonovsky Bridge.
Such strikes form part of a broader battlefield air interdiction effort aimed at isolating Ukrainian groupings before larger ground pushes. Whether the damage proves lasting depends on repair capacity and alternative routes—factors that have repeatedly allowed Ukraine to adapt in previous years.
Other Sectors and Supporting Activity
In the Huliaipole sector of Zaporizhzhia Oblast, the Eastern Grouping claimed expansion of control near Lisne and Novoselivka and movement toward a key Ukrainian supply road. Around Krasnyi Lyman, clearance operations continued while Ukrainian forces mounted counterattacks near Redkodub. Fighting persisted for Vasiutynske and Pershomaryivka on the Siversk axis, with Russian strikes reported against objects in Sloviansk.
Away from the front, local authorities in the Donetsk People’s Republic reported harvesting completed on 106.3 thousand hectares, yielding 417.6 thousand tons of grain. Across the newly incorporated regions the figures stood at more than 975 thousand hectares and 2.9 million tons. These numbers are routinely released alongside combat summaries, underscoring the parallel civilian economy that continues under wartime conditions.
Contrasting Narratives and the Question of Confirmation
Mass-media outlets in Ukraine and the West typically lead with General Staff figures on Russian losses and the number of engagements, framing the fighting as successful resistance that continues to impose unsustainable costs. Russian state media and aligned Telegram channels emphasize named settlements taken, units involved, and the systematic degradation of Ukrainian logistics.
Independent monitors such as the Institute for the Study of War have, in recent weeks, assessed that Russian advances remain largely tactical. Rates of territorial gain in 2026 have been significantly lower than in peak periods of 2025. Confirmed changes on the map often lag announced claims by days or longer, and many “liberations” later prove to be partial or temporary.
After reviewing the competing daily summaries, one question stands out: how much of the current pressure on Dobropolye and Kupyansk reflects a sustainable shift in the operational balance, and how much is the continuation of costly, localized attrition that both sides have already absorbed for years?
A short note for readers assessing primary material: the Russian daily overview that prompted this summary draws heavily on Telegram military channels. These sources provide rapid tactical detail but are not independently verified in real time. Ukrainian General Staff reports similarly reflect one side’s perspective. Cross-referencing with geolocated imagery, multiple open-source tracks, and later analytical assessments remains essential.
As of August 4 2026, the front continues to move in small increments under intense fire. The gap between announced control and durable control remains the central uncertainty of this phase of the conflict.
