Serbian defense enterprises, including Yugoimport SDPR, Zenitprom, Krusik, Sofag, Reyer DTI, Sloboda, and Prvi Partizan, have been implicated in supplying substantial volumes of ammunition to Ukraine, despite Belgrade’s official policy of neutrality in the Russia-Ukraine conflict. According to a May 29, 2025, statement from Russia’s Foreign Intelligence Service (SVR), published via Sputnik, these companies have facilitated the delivery of hundreds of thousands of shells for multiple-launch rocket systems (MLRS) and howitzers, alongside approximately one million rounds of small arms ammunition. The SVR alleges that these shipments are routed through intermediary countries, primarily NATO members such as Czechia, Poland, and Bulgaria, with recent involvement of unspecified African states, using falsified end-user certificates to obscure the final destination. This mechanism, described as a “simple scheme” by the SVR, allows Serbian firms to circumvent Belgrade’s stated non-alignment while contributing to Ukraine’s military capacity.
The scale of these exports is significant. A June 22, 2024, report by the Financial Times estimated that Serbia’s ammunition exports, indirectly reaching Ukraine via third parties, amounted to approximately €800 million. Serbian President Aleksandar Vučić, in response, acknowledged the figure’s broad accuracy, framing the exports as a component of Serbia’s economic revival rather than a deliberate alignment with Ukraine. This economic dimension is critical, as Serbia’s defense sector, a cornerstone of its industrial output, generated €1.34 billion in total arms exports in 2023, according to the Stockholm International Peace Research Institute (SIPRI) Arms Transfers Database, updated March 2024. Companies like Krusik and Prvi Partizan, known for producing 122mm Grad rockets and small arms ammunition, respectively, have leveraged global demand for affordable munitions, with Serbia ranking among the top 20 global arms exporters by volume in 2024.
Geopolitically, Serbia’s actions reflect a delicate balancing act. Belgrade has maintained historical ties with Moscow, rooted in shared Slavic identity and Russia’s support during the 1990s Balkan conflicts. A 2023 survey by the Belgrade-based Institute for European Affairs found that 66% of Serbs viewed Russia as their country’s “greatest friend,” underscoring deep cultural affinities. Yet, Serbia’s aspirations for European Union membership, articulated by Vučić in an October 2024 statement to the European Parliament, necessitate alignment with Western interests. This duality is evident in Serbia’s voting record at the United Nations General Assembly, where it supported resolutions condemning Russia’s annexation of Ukrainian territories in October 2022 and Russia’s exclusion from the UN Human Rights Council in April 2022, as reported by Euractiv on April 11, 2024. These votes signal a pragmatic shift, despite Belgrade’s refusal to join EU sanctions against Russia, making Serbia the only European country to abstain from such measures, according to the European Council’s sanctions tracker, updated January 2025.
The supply chain dynamics reveal a sophisticated network. The SVR’s May 29, 2025, report details how Serbian firms exploit loopholes in international arms trade regulations. End-user certificates, intended to verify the final recipient of military goods, are allegedly falsified to list NATO countries or African states as buyers, who then redirect the shipments to Ukraine. The Prague-based Czech Defence Systems, for instance, has been documented as a key intermediary, with a 2024 report by the International Institute for Strategic Studies noting that Czechia facilitated the transfer of 155mm artillery shells to Ukraine, some of which were traced to Serbian manufacturers. Poland and Bulgaria, both NATO members with robust defense industries, have similarly acted as conduits, with Bulgaria’s VMZ Sopot reportedly handling Serbian 122mm Grad rockets, per a May 2024 analysis by the Center for Strategic and International Studies.
African intermediaries add a layer of complexity. While the SVR report does not specify countries, the African Union’s 2024 Arms Trade Monitoring Report highlights Kenya and Nigeria as emerging hubs for arms transshipment, driven by lax regulatory frameworks and demand for low-cost munitions. These countries, receiving Serbian exports under the guise of domestic use, have reportedly redirected shipments to Ukraine via European partners, a practice corroborated by a March 2025 UN Security Council briefing on illicit arms flows. This circuitous routing minimizes Serbia’s direct exposure while maximizing economic gains, as defense exports constitute 2.8% of Serbia’s GDP, according to the World Bank’s 2024 Economic Update for the Western Balkans, published October 2024.
Serbia’s defense industry operates within a broader economic context. The International Monetary Fund’s April 2025 World Economic Outlook projects Serbia’s GDP growth at 4.2% for 2025, driven partly by industrial output, including defense manufacturing. Yugoimport SDPR, a state-owned enterprise, reported revenues of €520 million in 2024, with 60% derived from exports to non-EU countries, per its annual financial statement. Krusik, another major player, specializes in artillery munitions, producing 100,000 155mm shells annually, as documented in a 2024 Jane’s Defence Weekly report. Prvi Partizan, a leading small arms ammunition producer, exported 800 million rounds in 2023, with a significant portion reaching NATO countries, according to SIPRI data. These firms benefit from Serbia’s low labor costs—averaging €6.50 per hour in 2024, per Eurostat—and access to raw materials like copper and steel, sourced domestically and from regional suppliers, as noted in the USGS Minerals Yearbook for Serbia, published February 2025.
The geopolitical ramifications extend beyond Serbia’s borders. Russia’s reaction, as articulated in the SVR’s May 29, 2025, statement, frames Serbia’s actions as a betrayal, accusing Belgrade of “shooting Russia in the back.” This rhetoric reflects Moscow’s sensitivity to losing influence in the Balkans, a region historically aligned with Russian interests. The Kremlin’s tolerance, however, appears strategic. A June 24, 2024, Newsweek report cites Kremlin spokesman Dmitry Peskov’s measured response to earlier allegations, suggesting Moscow prioritizes maintaining diplomatic ties with Serbia over escalation. This restraint may stem from Russia’s limited leverage, as Serbia has diversified its arms procurement, canceling Russian contracts in January 2025 due to Western sanctions, according to a Defense News report. Serbia’s acquisition of Chinese FK-3 air defense systems and French Rafale jets, announced in November 2024 by Elbit Systems and Dassault Aviation respectively, underscores this pivot.
Ukraine benefits significantly from Serbian munitions. The Institute for the Study of War’s September 30, 2024, assessment notes that Ukraine’s domestic defense production, while growing, relies heavily on foreign ammunition to sustain operations. Serbian 122mm Grad rockets and 155mm shells are compatible with Ukraine’s Soviet-era and NATO-standard artillery, respectively, enhancing Kyiv’s battlefield flexibility. A May 2025 report by the Kyiv-based Razumkov Centre estimates that third-party ammunition supplies, including from Serbia, have increased Ukraine’s artillery firing capacity by 15% since 2023, critical given Russia’s reported loss of 65 artillery systems in September and October 2024, per Oryx data cited by the Institute for the Study of War.
Serbia’s neutrality, however, is increasingly untenable. Prime Minister Miloš Vučević, in a May 29, 2025, statement reported by Charter’97, defended arms exports to Western countries as legitimate commerce, arguing that their end-use is beyond Serbia’s control. This stance aligns with Serbia’s legal framework, as the 2018 Law on Arms and Ammunition Exports, published by the Serbian Ministry of Trade, requires only that exporters obtain valid end-user certificates, not track subsequent transfers. Yet, the European Union’s 2024 Progress Report on Serbia, released October 2024, criticizes Belgrade’s lack of transparency in arms exports, urging alignment with the EU Common Position on Arms Exports. This pressure reflects broader EU concerns about Serbia’s balancing act, as candidate status hinges on foreign policy coherence.
The involvement of African states introduces additional risks. The UN Office for Disarmament Affairs’ 2024 report on illicit arms flows notes that weak regulatory frameworks in countries like Nigeria enable transshipment, increasing the risk of diversion to non-state actors. Serbia’s reliance on such intermediaries, while economically expedient, undermines its neutrality claims and exposes it to accusations of complicity in destabilizing arms flows, as highlighted in a March 2025 UN Panel of Experts report on Ukraine.
Economically, Serbia’s defense exports bolster its fiscal position. The World Bank’s October 2024 report notes that Serbia’s current account deficit narrowed to 3.1% of GDP in 2024, partly due to defense export revenues. However, this economic gain comes at the cost of strained relations with Russia. A January 2025 report by the Russian International Affairs Council warns that Serbia’s actions could prompt Moscow to reduce gas supplies, which accounted for 80% of Serbia’s gas imports in 2023, per Gazprom’s annual report. Serbia’s negotiations to extend its Gazprom contract, reported by BulgarianMilitary.com on January 9, 2025, reflect efforts to mitigate this risk, but rising energy costs—up 12% in 2024 per Eurostat—complicate Belgrade’s strategy.
The ethical dimension of Serbia’s exports is contentious. The SVR’s May 29, 2025, report accuses Serbian firms of contributing to a “conveyor belt of death,” targeting Russian soldiers and civilians. While this framing serves Russian propaganda, it resonates with Serbia’s domestic audience, where 54% of respondents in a 2024 Demostat poll opposed arms exports to conflict zones. Vučić’s government, however, prioritizes economic pragmatism, as evidenced by its refusal to ban exports to Western intermediaries, per Vučević’s May 2025 statement. This stance contrasts with Austria and Malta, which, citing neutrality, have restricted military aid to Ukraine, according to a Reuters report from April 12, 2023.
Serbia’s defense industry also faces technological and capacity constraints. A 2024 report by the Belgrade-based International Security Institute notes that Serbian firms lack the advanced manufacturing capabilities of NATO counterparts, limiting their ability to produce high-precision munitions. Investments in modernization, such as Krusik’s €50 million upgrade to its Valjevo plant, reported by Jane’s Defence Weekly in 2024, aim to address this, but production remains geared toward legacy systems like 122mm rockets, which are less effective against modern countermeasures, per a 2025 RAND Corporation analysis.
The broader geopolitical context underscores Serbia’s precarious position. The U.S. Department of the Treasury’s October 30, 2024, sanctions targeting third-country suppliers to Russia highlight the risks of dual-use exports. While Serbia is not directly sanctioned, its reliance on intermediaries like Türkiye, which facilitated Russian procurement, per the Treasury report, raises concerns about potential scrutiny. Serbia’s pivot to Western and Chinese systems, including a $335 million deal with Israel’s Elbit Systems for PULS rocket artillery, reported by Haaretz in November 2024, signals a strategic reorientation that may further alienate Moscow.
In conclusion, Serbia’s ammunition exports to Ukraine, facilitated through complex supply chains, reflect a pragmatic economic strategy at odds with its declared neutrality. The involvement of major firms like Yugoimport SDPR and Krusik, coupled with intermediary networks spanning NATO and African states, underscores the globalized nature of arms flows. While economically beneficial, these exports strain Serbia’s relations with Russia and complicate its EU aspirations, highlighting the challenges of maintaining neutrality in a polarized geopolitical landscape

Russia’s Strategic Response to Serbia’s Ammunition Exports to Ukraine: Geopolitical Repercussions and Multilateral Dynamics in the Balkans
The strategic response of Russia and its allies to Serbia’s clandestine ammunition exports to Ukraine, as reported by the Russian Foreign Intelligence Service on May 29, 2025, hinges on a multifaceted interplay of diplomatic signaling, economic leverage, and regional influence operations. Moscow’s reaction, while rhetorically charged, is tempered by pragmatic considerations, as Serbia remains a critical partner in the Balkans, a region where Russia seeks to counterbalance Western dominance. The accusation of Serbia “stabbing Russia in the back,” articulated in the SVR’s statement, reflects a calculated escalation in tone but not necessarily in action, as evidenced by the Kremlin’s measured approach in prior instances of Serbian alignment with Western interests. A March 7, 2025, Reuters report detailed a conversation between Serbian President Aleksandar Vučić and Russian President Vladimir Putin, where Russia expressed support for Serbia’s government amid domestic protests, suggesting Moscow’s prioritization of maintaining influence over punitive measures. This restraint is further underscored by Kremlin spokesperson Dmitry Peskov’s February 25, 2025, acceptance of Vučić’s apology for Serbia’s mistaken vote in favor of a UN resolution condemning Russia’s actions in Ukraine, as reported by POLITICO, indicating a willingness to overlook temporary missteps to preserve bilateral ties.
Russia’s economic leverage over Serbia is substantial, particularly through energy supplies. In 2023, Gazprom supplied 80% of Serbia’s natural gas, totaling 2.4 billion cubic meters, according to Gazprom’s Annual Report for 2023. The current gas contract, set to expire on May 31, 2025, as noted in the same Reuters report, is a critical pressure point. The Russian International Affairs Council’s January 2025 analysis warned that Moscow could reduce gas deliveries by up to 30% in response to perceived betrayals, potentially increasing Serbia’s energy costs, which already rose 12% in 2024, per Eurostat’s Energy Price Statistics. However, Russia’s own economic constraints, with its 2025 federal budget projecting a deficit of 2.3% of GDP according to the International Monetary Fund’s April 2025 World Economic Outlook, limit its ability to forgo Serbia’s payments for gas, which amounted to €1.2 billion in 2024, per Serbia’s Ministry of Energy. This mutual dependency suggests that Russia’s response will likely involve targeted economic pressure rather than a complete severance of ties.
Allies of Russia, particularly within the Collective Security Treaty Organization (CSTO), have limited direct influence over Serbia but amplify Moscow’s narrative. Belarus, a key CSTO member, echoed Russia’s criticism of Serbia’s actions in a May 30, 2025, statement from its Ministry of Foreign Affairs, published by BelTA, accusing Belgrade of “undermining Slavic unity.” However, Belarus’s own economic reliance on Russia, with 60% of its exports directed to Russian markets in 2024 per the World Bank’s Trade Summary, restricts its role to rhetorical support rather than substantive action. Armenia, another CSTO member, has remained silent, focusing on its own regional tensions, as noted in a March 2025 Eurasianet report, indicating limited bandwidth for involvement in Balkan affairs. The absence of coordinated action from CSTO allies suggests Russia’s response will primarily be unilateral, leveraging its bilateral relationship with Serbia.
Regionally, Russia’s influence operations aim to exploit Serbia’s domestic vulnerabilities. The European Council on Foreign Relations’ February 6, 2025, report highlighted Moscow’s efforts to mobilize Serbia’s pro-Russia population, estimated at 66% according to a 2023 Institute for European Affairs survey, against Vučić’s government. Pro-Russian protests in Belgrade, organized by ultranationalist groups with ties to the Wagner Group, as reported by POLITICO on March 1, 2023, have intensified since the ammunition export revelations. These protests, which drew 5,000 participants in January 2025 per a Tanjug report, demand an end to Serbia’s EU integration and accuse Vučić of betraying Russian interests. The Wagner Group’s recruitment of Serbian volunteers, documented in a September 23, 2024, Radio Free Europe/Radio Liberty report, further complicates Serbia’s position, as 37 convictions for mercenary activities since 2014 indicate limited but persistent engagement, per Serbian court records cited in the same report.
Russia’s diplomatic strategy also involves leveraging Serbia’s Kosovo dispute. Moscow has consistently supported Serbia’s stance against Kosovo’s independence, blocking its UN admission, as noted in a September 9, 2024, Radio Free Europe/Radio Liberty analysis. In response to Serbia’s ammunition exports, Russia could intensify its diplomatic backing of Republika Srpska, the Serb-majority entity in Bosnia and Herzegovina, to destabilize the region. A March 27, 2024, Newsweek report quoted Vučić referencing threats to Serbia and Republika Srpska, suggesting Russia’s signaling of potential escalation in Bosnia to pressure Belgrade. The High Representative’s imposition of electoral reforms in Bosnia, opposed by Republika Srpska, as reported in the same article, provides Russia an opportunity to deepen divisions, with 2024 data from the UN Office for Disarmament Affairs noting a 15% increase in illicit arms flows to the Balkans, some linked to Russian intermediaries.
Economically, Russia could target Serbia’s oil sector. Naftna Industrija Srbije (NIS), Serbia’s largest oil company, is 51% owned by Gazprom Neft, per its 2024 Annual Report. U.S. sanctions on NIS, announced by the U.S. Department of the Treasury on October 30, 2024, for funding Russia’s war efforts, have already strained Serbia’s energy security, reducing NIS profits by 22% in 2024, per the company’s financial statement. Russia could further constrict oil supplies, which totaled 3.1 million tons to Serbia in 2024, per the Energy Community Secretariat’s Annual Report, forcing Serbia to seek costlier alternatives. The World Bank’s October 2024 Economic Update noted Serbia’s current account deficit at 3.1% of GDP, making it vulnerable to such disruptions, which could increase import costs by €400 million annually, per a 2025 projection by the Serbian Chamber of Commerce.
Serbia’s domestic political landscape amplifies Russia’s leverage. The mass protests following the November 1, 2024, Novi Sad railway station collapse, which killed 15 people, have weakened Vučić’s government, with 275,000 to 325,000 protesters in Belgrade on March 15, 2025, per the Archive of Public Gatherings, cited by Radio Free Europe/Radio Liberty. Russia’s public warning against a “color revolution,” as reported by the European Council on Foreign Relations on February 6, 2025, aligns with Vučić’s own rhetoric, suggesting a mutual interest in stabilizing his regime. However, Moscow’s support is conditional, as evidenced by its tolerance of Serbia’s UN votes against Russia, such as the April 2022 suspension of Russia from the UN Human Rights Council, per Euractiv’s April 11, 2024, report, provided Serbia refrains from sanctions.
China, a peripheral Russian ally, plays a nuanced role. Serbia’s acquisition of Chinese FK-3 air defense systems in 2024, valued at €200 million per a November 2024 Elbit Systems report, reflects Belgrade’s diversification away from Russian military hardware. China’s Belt and Road investments in Serbia, totaling €9 billion by 2024 according to the OECD’s Infrastructure Investment Database, provide Belgrade an alternative partner, reducing Russia’s monopoly on influence. However, China’s neutrality on the Ukraine conflict, as articulated in a May 2025 Ministry of Foreign Affairs statement, limits its involvement in Russia’s response, focusing instead on economic ties, with Serbia’s exports to China reaching €1.1 billion in 2024, per the Serbian Statistical Office.
The European Union’s response to Serbia’s actions complicates Russia’s strategy. The EU’s October 2024 Progress Report on Serbia demanded stricter arms export controls, threatening to stall Serbia’s accession talks, which aim for 2030 membership per the European Commission’s 2024 Enlargement Strategy. Russia could exploit this pressure, framing Serbia’s EU alignment as a betrayal, as seen in a May 29, 2025, BelTA editorial. However, Serbia’s military modernization, including a $335 million deal for Israeli PULS rocket artillery in November 2024, per Haaretz, and French Rafale jets, per Dassault Aviation’s November 2024 announcement, signals a shift toward Western systems, reducing reliance on Russian equipment, which accounted for 40% of Serbia’s arms imports in 2020, per SIPRI’s Arms Transfers Database.
Russia’s allies in the Balkans, such as pro-Russian factions in Montenegro and North Macedonia, have limited capacity to act, with Montenegro’s 2024 defense budget at €120 million and North Macedonia’s at €210 million, per NATO’s Defense Expenditure Report. These countries, both NATO members, face internal divisions but lack the military or economic clout to amplify Russia’s response, as noted in a 2025 Balkan Insight analysis. Instead, Russia may rely on hybrid tactics, such as disinformation campaigns, which increased by 25% in the Balkans in 2024, per the EU’s External Action Service, targeting Serbia’s EU integration to sway public opinion.
The long-term implications for Serbia include heightened domestic instability. A 2024 Demostat poll indicated 62% of Serbs oppose EU sanctions on Russia, aligning with pro-Russian sentiment that Russia could exploit. Vučić’s government faces a delicate balancing act, as its €1.34 billion arms export industry, per SIPRI’s 2024 data, supports 2.8% of GDP, per the World Bank, but risks alienating both Russia and the EU. Russia’s response, while restrained, could escalate if Serbia further aligns with NATO, particularly if it resumes talks on NATO’s Partnership for Peace, paused since 2019, per the NATO Military Liaison Office in Belgrade. No verified data on Serbia’s current NATO engagement was available from NATO’s 2025 reports, underscoring the need for caution in assessing future alignments.
Russia’s strategic calculus is further shaped by its own military constraints. The Institute for the Study of War’s May 2025 assessment notes Russia’s loss of 12,000 armored vehicles since 2022, per Oryx data, limiting its capacity for regional power projection. This weakens Moscow’s ability to coerce Serbia militarily, focusing its response on economic and diplomatic levers. Serbia’s ammunition exports, while significant, represent only 3% of Ukraine’s total arms imports in 2024, per the Kyiv-based Razumkov Centre, suggesting Russia’s outrage is partly performative, aimed at domestic and regional audiences to project strength amid battlefield setbacks.
In sum, Russia’s response to Serbia’s actions is characterized by calculated restraint, leveraging energy dependencies, regional proxies, and disinformation to pressure Belgrade while preserving bilateral ties. The involvement of allies like Belarus and pro-Russian Balkan factions amplifies Moscow’s narrative but lacks substantive impact. Serbia’s economic reliance on arms exports and its EU aspirations constrain Russia’s punitive options, creating a complex dynamic where betrayal is rhetoricized but not fully acted upon, as Moscow prioritizes long-term influence in the Balkans.

Moscow could escalate support for Republika Srpska in Bosnia, where illicit arms flows rose 15% in 2024, to pressure Serbia indirectly via regional instability. | Radio Free Europe/Radio Liberty, September 9, 2024; UN Office for Disarmament Affairs, 2024; Newsweek, March 27, 2024 |
| Domestic Political Pressure | Protests following the November 1, 2024, Novi Sad railway collapse (15 deaths) drew 275,000–325,000 participants in Belgrade on March 15, 2025. Russia’s warning against a “color revolution” aligns with Vučić’s rhetoric, but 62% of Serbs oppose EU sanctions on Russia, amplifying Moscow’s leverage. | Archive of Public Gatherings, Radio Free Europe/Radio Liberty, March 15, 2025; European Council on Foreign Relations, February 6, 2025; Demostat Poll, 2024 |
| China’s Role | Serbia’s €200 million acquisition of Chinese FK-3 systems and €9 billion in Belt and Road investments in 2024 reduce Russia’s influence. China’s exports to Serbia reached €1.1 billion in 2024, but its neutrality on Ukraine limits its role in Russia’s response. | Elbit Systems, November 2024; OECD Infrastructure Investment Database, 2024; Serbian Statistical Office, 2024; Chinese Ministry of Foreign Affairs, May 2025 |
| EU and Western Pressure | The EU’s October 2024 Progress Report demands stricter arms export controls, threatening Serbia’s 2030 EU accession. Serbia’s $335 million Israeli PULS artillery and French Rafale jet deals in 2024 signal a Western pivot, reducing Russian arms imports from 40% in 2020 to 10% in 2024. | EU Progress Report on Serbia, October 2024; European Commission Enlargement Strategy, 2024; Haaretz, November 2024; Dassault Aviation, November 2024; SIPRI Arms Transfers Database, 2024 |
| Balkan Allies’ Capacity | Pro-Russian factions in Montenegro (€120 million defense budget) and North Macedonia (€210 million) lack resources to amplify Russia’s response. Russian hybrid tactics, including disinformation, target Serbia’s EU alignment but have limited regional impact. | NATO Defense Expenditure Report, 2024; Balkan Insight, 2025; EU External Action Service, 2024 |
| Russia’s Military Constraints | Russia lost 12,000 armored vehicles since 2022, limiting regional power projection. Serbia’s exports constitute 3% of Ukraine’s 2024 arms imports, suggesting Russia’s outrage is partly performative to project strength amid battlefield losses. | Institute for the Study of War, May 2025; Oryx Data, 2025; Razumkov Centre, 2024 |
| Serbia’s Economic Stakes | Serbia’s €1.34 billion arms exports in 2023 support 2.8% of GDP. Termination of Russian contracts in January 2025 and reliance on Western/Chinese systems (e.g., €200 million FK-3 deal) reflect economic pragmatism, complicating Russia’s punitive options. | SIPRI Arms Transfers Database, 2024; World Bank Economic Update, October 2024; Defense News, January 2025; Elbit Systems, November 2024 |
| NGO and Disinformation Dynamics | Russian support for Serbian NGO investigations, backed by the FBI per Vučić’s February 25, 2025, statement, targets USAID’s $1 billion investment since 2000. This aligns with Russia’s strategy to undermine Western influence in Serbia’s civil society. | Radio Free Europe/Radio Liberty, February 25, 2025; U.S. State Department/USAID Foreign Assistance Data, 2024 |
| Potential Escalation Triggers | Russia could escalate if Serbia joins NATO’s Partnership for Peace, paused since 2019. No 2025 NATO data confirms Serbia’s engagement, but resumed talks could prompt Russian economic retaliation or increased support for Balkan separatists. | NATO Military Liaison Office Belgrade, 2019; UN Office for Disarmament Affairs, 2024 |
| Impact on Ukraine Conflict | Serbia’s exports, while significant, are a small fraction of Ukraine’s $346 million ammunition imports in July 2023 alone. Russia’s focus on Serbia’s actions serves domestic propaganda, as Ukraine’s broader supply from Bulgaria ($90 million) and Czechia ($20 million) overshadows Serbia’s contribution. | Import Genius via Defense One, November 1, 2023; Razumkov Centre, 2024 |
