Ukraine's Military Strategy Under General Syrskyi, 2024–2025

The Command Transition: Why Zaluzhny Was Replaced

General Valerii Zaluzhny was the face of Ukraine's military resistance from the first days of Russia's February 2022 invasion. His steady, professional public communications, his relationships with NATO military counterparts, and his strategic guidance through Ukraine's 2022 liberation campaigns made him enormously popular — both with the Ukrainian public (regularly polling as the country's most trusted figure) and in Western capitals. His November 2023 article acknowledging the war had reached "stalemate" created political friction with Zelensky's more mobilizing public messaging.

The relationship between Zelensky and Zaluzhny deteriorated through late 2023 and early 2024. Political observers identified multiple sources of tension: disagreements over mobilization and manpower policy (Zaluzhny demanding more decisive mobilization than Zelensky was willing to order before parliamentary processes); disputes over battlefield conduct; and the political implications of Zaluzhny's independent popularity at a time the president sought consolidated political leadership for the wartime state.

Zaluzhny was dismissed and appointed as Ukraine's ambassador to the United Kingdom on 8 February 2024. Syrskyi was appointed the same day. The transition was framed as standard personnel management but was widely understood as politically driven.

Syrskyi's Background and Reputation

Oleksandr Syrskyi was born in Russia (Vladimir Oblast) in 1965, educated at Moscow's Military Academy, and served in the Soviet army before transitioning to Ukraine's armed forces after 1991. His Russian origins were occasionally noted in political commentary and drew some criticism, though his loyalty to Ukraine through the war was not seriously questioned.

Syrskyi commanded Ukrainian Ground Forces from 2019 and was responsible for some of the war's most consequential operations: the defense of Kyiv in spring 2022 (successfully repelling the Russian advance toward the capital), the September 2022 Kharkiv counteroffensive (the most spectacular Ukrainian operational success of the war), and the prolonged and costly Bakhmut defense. His record was mixed: brilliant in Kyiv and Kharkiv, controversial in Bakhmut where his decision to hold the city far beyond its military utility generated significant casualties.

Command Style: Differences from Zaluzhny

Where Zaluzhny was a communicative, politically sensitive commander who maintained a high public profile and developed a strong external persona, Syrskyi operates differently. He is known for frequent frontline visits — flying in helicopters to forward positions, conducting personal staff briefings with divisional and corps commanders, and managing operational details at a tactical level unusual for a commander-in-chief.

Western military advisors working with Ukraine's command noted both the advantages and disadvantages of this style. The advantage: Syrskyi's genuine operational knowledge of frontline conditions and direct personal authority over commanders who knew he might appear at their positions without warning. The disadvantage: risk of operational-level decisions overcrowding strategic-level thinking, and less bandwidth for the political and alliance management functions that were equally important for Ukraine's war effort.

Syrskyi also has a reputation as more willing to hold positions under Russian pressure — a characteristic associated with both the Bakhmut controversy and subsequent Donbas defensive operations. Critics describe this as attritionally costly; supporters describe it as denying Russia easy territorial gains at a time when any Russian advance was politically damaging.

Inheriting the Avdiivka Aftermath

Syrskyi was appointed literally during the final battles for Avdiivka — a major fortified position in Donetsk Oblast that Russia had been attacking since October 2023. On 17 February 2024 — nine days after Syrskyi's appointment — Zelensky announced the withdrawal from Avdiivka after months of siege.

The Avdiivka fall (Russia's most significant territorial capture since Bakhmut in May 2023) created immediate pressure on the new commander. The withdrawal was contested in its execution — some Ukrainian forces were cut off during the retreat, generating casualties higher than a planned withdrawal might have produced. Syrskyi ordered the withdrawal; its timing and execution became points of criticism. Whether the difficulties were attributable to the transition period, the inherent complexity of extracting forces from a contested encirclement, or specific command decisions was debated.

The Avdiivka aftershock immediately shaped Syrskyi's command priorities: stop further large-scale losses along the Donetsk front, restore defensive depth, and identify where to hold rather than where to attack. The summer 2024 Kursk decision represented the offensive element of this defensive rebalancing.

Responding to the May 2024 Kharkiv Offensive

Russia's surprise 10 May 2024 offensive in northern Kharkiv Oblast was the first major test of Syrskyi's strategic management under crisis conditions. His response — rapid emergency reserve commitment, personal coordination of the defensive effort, and Zelensky's corresponding public invocation of the failure to prevent the initial advance — established patterns that would define his command. Syrskyi committed substantial forces to halt the Kharkiv advance, accepting the cost to other fronts, and successfully prevented the offensive from achieving its apparent deep objectives.

The experience reinforced Syrskyi's interest in striking cross-border — if Ukraine could threaten Russian staging areas in Belgorod Oblast, the May 2024 offensive might have been deterred or degraded before launch. This thinking fed into the Kursk operational planning that came just three months later.

The Kursk Incursion Decision, August 2024

On 6 August 2024, Ukrainian forces crossed into Russia's Kursk Oblast in the largest Ukrainian offensive operation since the September 2022 Kharkiv counteroffensive. The operation, planned under Syrskyi's direction, achieved almost total operational surprise — Russia had not concentrated defensive forces in the frontier zone, apparently not anticipating that Ukraine would attack into Russia itself.

Ukrainian armored and mechanized forces advanced rapidly, seizing over 1,000 km² of Russian territory in the first weeks, including the town of Sudzha and dozens of villages. The advance created a Ukrainian-held salient inside Russia proper — the only such territory Ukraine had held since the war began.

The Kursk decision was controversial among Western military advisors and within Ukraine's military establishment. Some senior Ukrainian officers and officials privately expressed concern that committing significant forces and equipment to Kursk diverted resources from the increasingly strained Donetsk front. However, Syrskyi and Zelensky were aligned on the decision, which they justified through multiple strategic arguments: creating Russia's own "Donbas problem" inside Russia, forcing Russia to divert forces from Ukraine, establishing negotiating leverage through Ukrainian-held Russian territory, and demonstrating strategic initiative to Western partners.rategic initiative to Western partners.

Kursk: Objectives and Assessment Through 2025

By early 2025, the Kursk operation's outcomes were mixed but consequential. Russia committed approximately 50,000 troops to Kursk, including the deployment of North Korean special operations forces (10,000–12,000 DPRK soldiers) — Russian forces that might otherwise have been used in Donetsk Oblast. This attritional diversion was a genuine Ukrainian strategic success.

However, Russian forces gradually reduced the Ukrainian-held salient through autumn 2024 and winter 2024–2025. Ukraine sustained high casualties and equipment losses maintaining the bridgehead. The salient shrank significantly under Russian counter-pressure. The question of whether the Kursk operation's costs were justified by its strategic benefits became one of the more contested assessments of Syrskyi's command.

The bridgehead also became a significant factor in peace negotiations — Ukraine's ability to claim it held Russian territory provided rhetorical and potentially practical leverage in any ceasefire/exchange discussions. Syrskyi publicly defended the Kursk operation as serving this negotiating function even as its military footprint diminished.

Managing the Donbas Defensive Battle

The Donetsk front presented Syrskyi with the war's most intractable military problem: systematic Russian pressure along a 200+ km arc from Chasiv Yar in the north to Marinka in the south, with Russia demonstrating consistent ability to advance incrementally at the cost of enormous casualties. Russian forces had developed an operational methodology combining glide bomb use, infantry assault with suppressive fire, and engineering work that ground through Ukrainian positions at a pace of hundreds of meters to low kilometers per month.

Syrskyi's approach to Donetsk management emphasized: establishing defensive depth rather than forward-edge linear defense (reducing exposure to direct Russian fire); selective fighting withdrawal from positions that became tactically untenable to preserve force; prioritizing anti-drone defense layers; and attempting to restore operational reserves that could counterattack Russian advance and restore lost positions.

The Pokrovsk direction became the most critical threat by late 2024: if Russia took Pokrovsk — a major logistics hub — it would fundamentally complicate Ukrainian defensive organization across a broad front. Syrskyi committed significant reserves to slow the Pokrovsk advance, accepting that other sections of the Donetsk front would be less defended as trade-offs.

Drone Warfare Prioritization

Under Syrskyi, Ukraine's drone warfare programs received increased strategic emphasis as a partial compensator for the ammunition and equipment shortages that constrained conventional firepower. Ukraine's FPV drone production scaling — from hundreds per month in 2022 to projections of over 1 million units per year by 2025 — was supported by the military leadership as a force multiplier enabling Ukraine to engage Russian armored vehicles, supply trucks, and personnel at far lower cost per kill than artillery ammunition.

Long-range strike drones (Liutyi, Bober, Beaver, Palianytsia) that could reach targets deep inside Russia enabled a campaign against Russian energy infrastructure, oil refineries, ammunition depots, and military industrial facilities that Syrskyi explicitly endorsed as a war-winning strategy lever: degrade Russia's ability to produce and supply its war through deep strike, not just fight on the frontline.

The Deep Strike Campaign in Russia

Ukraine dramatically expanded its deep strike campaign against Russian territory during Syrskyi's command. Drone attacks on oil refineries in Saratov, Ryazan, and elsewhere; strikes on Tatarstan aviation plant producing combat aircraft; attacks on Russian military air bases; and hundreds of smaller strikes against Russian border region infrastructure became consistent features of the war. Syrskyi endorsed the strategic logic of these operations: if Russia's oil export revenues fund the war, striking refineries reduces war revenue; if Russian aircraft production maintains air superiority, striking the factories complicates that capacity.

The deep strike campaign also served domestic morale purposes and demonstrated agency to Ukrainian public and Western partners — that Ukraine was actively pursuing war termination through cost imposition on Russia rather than purely absorbing Russian attacks.

Ukrainian Military Strategy by 2025

By early 2025, Ukrainian military strategy under Syrskyi had developed around several integrated pillars: flexible elastic defense in Donbas — conceding ground selectively to preserve force, avoiding mass encirclements, restoring positions through local counterattacks; strategic deep strikes against Russian infrastructure, logistics, and military-industrial capacity; the Kursk bridgehead as negotiating asset; drone warfare at industrial scale as firepower substitute; special operations inside Russia targeting high-value military networks; and diplomatic leverage through military performance to demonstrate to Western partners that Ukraine remained a viable fighting force justifying continued support.

The strategy was constrained by the same factors that had defined the entire war: manpower shortages (Ukraine's mobilization challenges produced insufficient trained infantry replacements), ammunition constraints (artillery shell supply remained below consumption rates even with US aid resumption), and the political uncertainties of Western support. But it represented a sophisticated adaptation to binding structural constraints — fighting asymmetric where possible and absorbing russian conventional pressure where the front demanded it.

Syrskyi's legacy assessment by 2025 was mixed but significant: he had prevented a Russian breakthrough despite extraordinary pressure, launched the most operationally daring Ukrainian operation of the war (Kursk), and established a drone warfare-centric military posture that was reshaping modern warfare doctrine beyond Ukraine's war. The costs paid along the way — casualties, territorial losses, the Kursk attrition — were the inescapable arithmetic of fighting a larger power at the limit of Ukraine's capacity.
