A confidential EU document, seen by Euronews, reveals that returning soldiers from Ukraineβs front line are bringing weapons and military equipment into the European Union. This development raises immediate concerns that battlefield components could begin circulating within the bloc, prompting EU ambassadors to discuss the risk of firearms diversion today. The document states that member states have reported weapon components and military equipment in the possession of returning combatants. It warns that these detections demonstrate a potential risk of military components or other battlefield equipment being transported from Ukraine into the EU, even if not necessarily connected to organised smuggling activities.
The Expanding Border Regime
This alarm over weapons is already being leveraged to justify a tightening of Europe's border regime. In recent months, several EU countries pushed to bar former and current Russian combatants from entering the bloc, citing potential security risks like sabotage and hybrid attacks on European soil. This proposed ban, initially part of the 21st sanctions package, was ultimately watered down following opposition from France and Italy. However, EU foreign policy chief Kaja Kallas noted "broad support" for a visa ban after an attempted drone attack in Leipzig, where a suspect reportedly entered the Schengen area on an Italian tourist visa. Estonia has since launched an intelligence-sharing operation with other countries on the so-called eastern flank, pooling entry-refusal decisions against identified Russian combatants based on judicial or administrative rulings.
The document further states that "foreign fighters, either volunteers or mercenaries, continue to pose a risk, as they acquire military skills and experience that could be further exploited once they withdraw from the conflict zone to engage in criminal activities or terrorism." This broad categorisation extends suspicion to all individuals with combat experience, regardless of their affiliation. The concern isn't limited to Russian combatants; it also encompasses Ukrainians returning from the frontline, particularly in member states hosting large numbers of Ukrainian refugees, such as Germany, Poland, and Czechia. Authorities in these countries argue the security issue affects the EU as a whole because they are part of Schengen, suggesting that soldiers reuniting with their families are unlikely to sell those weapons legally.
Manufacturing Risk, Expanding Control
Despite the heightened rhetoric, a report published in March by the Global Initiative Against Transnational Organized Crime indicated there is currently no substantial weapon inflow from Ukraine to neighbouring countries. It did, however, acknowledge that weapon circulation remains a "structural risk." Kyiv has already established a National Firearms Focal Point, which supplies Europol with lists of seized, stolen, or lost firearms. Europol, the EU's law enforcement agency, is due to establish a dedicated Firearms Hub by the first quarter of 2027 to improve the analysis and exchange of data on seized weapons. Ukraine is also expected to adopt a dedicated roadmap on firearms trafficking by the end of this year, mirroring a model already undertaken in the Western Balkans. Specific benchmarks on this issue have been written into Ukraine's accession negotiations, further embedding EU control over its neighbours' internal security.
Frontex and the Militarized Frontier
Frontex, the EU's notorious border agency, has already issued specific instructions for border guards and customs authorities on firearm diversion, with a direct focus on Ukraine. The confidential document explicitly identifies "the proliferation and diversion of firearms and other SALW [Small Arms and Light Weapons]" as "one of the most significant long-term concerns" stemming from Russia's war of aggression against Ukraine. Yet, the same document quietly admits that "so far, few weapons have been seized and few arrests made." This discrepancy highlights how the perceived threat of weapon proliferation is being used to justify an expansion of border surveillance and control, further militarising the EU's external frontiers under the guise of security, even as evidence of a widespread problem remains scarce. The focus on returning combatants, including those who fought against Russian aggression, underscores the border regime's inherent suspicion of all movement, ultimately criminalising those who cross its lines.
