Türkiye Joins Serbia’s First NATO Military Exercise as Balkan Security Shifts
By Bosphorus News Geopolitics Desk
Türkiye is taking part in Serbia's first military exercise with NATO, a development that places Ankara inside one of the Western Balkans' most delicate security tracks, where Belgrade's declared neutrality, the unresolved Kosovo dispute and the legacy of NATO's 1999 air campaign still shape every military contact with the alliance.
NATO–Serbia Exercise 2026 opened on May 12 at Military Base South and the Borovac Training Area near Bujanovac in southern Serbia. NATO's Joint Force Command Naples said the exercise will run until May 23 and bring together around 600 personnel from the Serbian Armed Forces and three NATO countries: Italy, Romania and Türkiye.
The exercise focuses on military-civilian cooperation, interoperability, base protection, crowd control, checkpoint operations and activities in an urban environment. Planning began in early 2025 under the Serbian Armed Forces and NATO's Joint Force Command Naples, with planners and observers also drawn from France, Germany, Montenegro, Romania, Serbia, Türkiye, the United Kingdom and the United States.
Serbia's Ministry of Defence presented the drill as cooperation aimed at preserving peace and stability in the region, while NATO said the exercise is being conducted under the Partnership for Peace framework and with respect for Serbia's policy of military neutrality.
That phrasing is central to the politics of the exercise. Serbia remains outside NATO, continues to define itself as militarily neutral, maintains ties with Russia and China, and still keeps its European Union track formally alive. Public memory of NATO's 1999 bombing campaign during the Kosovo war leaves little room for a conventional pro-alliance narrative in Belgrade, yet Serbia's armed forces are increasingly operating in formats that require practical contact with NATO standards and procedures.
Serbian President Aleksandar Vučić announced the exercise in March while stressing that Serbia's neutrality would remain intact. The distinction allows Belgrade to avoid the domestic politics of NATO membership while still expanding controlled military cooperation with the alliance, especially in areas framed as interoperability, crisis response and regional stability.
Türkiye's role gives the drill a sharper Balkan meaning. Ankara is not merely listed among the three NATO members on the ground in southern Serbia. It is also a major actor in Kosovo, a NATO ally with historical depth in the Balkans, and one of the few regional powers able to maintain active channels with both Belgrade and Pristina without fully absorbing either side's political reading of the dispute.
That balancing act has become more visible over the past year. Türkiye has strengthened Kosovo's defence capacity, including through military support that Bosphorus News detailed as Balkan security tensions rose. Those steps remain sensitive in Belgrade, which does not recognise Kosovo's independence and treats Pristina's security development as a direct political concern.
At the same time, Türkiye has stayed active inside the NATO peacekeeping structure in Kosovo. A recent meeting between the Turkish KFOR commander and Serbia's army chief, covered by Bosphorus News in the Kosovo security file, showed how Ankara's military diplomacy moves across the Belgrade-Pristina line without abandoning its formal position on Kosovo.
The Serbia exercise therefore belongs to a wider Western Balkan security environment rather than a narrow bilateral or technical training file. NATO and European military institutions are increasingly treating the region as a connected security front, a pattern Bosphorus News examined in its coverage of NATO and EU military chiefs.
The Turkish angle also shows how far Ankara-Belgrade relations have moved from the tensions of the 1990s. Türkiye recognises Kosovo and remains close to Pristina, but it has also built deeper trade, infrastructure, defence and political ties with Serbia. Economic pragmatism and direct political contact have repeatedly limited the damage from periodic disputes over Kosovo, drone deliveries and regional rhetoric.
The contradiction remains the point. Türkiye can stand inside Serbia's first NATO military exercise while supporting Kosovo's defence capacity and holding a senior role in the NATO-led KFOR mission. That is not a neat diplomatic formula; it is the practical shape of Ankara's Balkan policy, which depends on remaining present in overlapping formats that do not always sit comfortably together.
The timing also matters before the NATO summit in Ankara. Western Balkan security, Kosovo stability and NATO's southeastern posture are all moving higher on the alliance agenda, and Türkiye's participation in the Serbia drill gives Ankara a visible role in that process before it hosts allied leaders.
Serbia is not entering NATO through this exercise, and Belgrade will continue to protect the language of neutrality for domestic and geopolitical reasons. Yet the military reality is becoming harder to ignore: NATO is no longer fully outside Serbia's operational routine, and Türkiye's presence in the first drill places Ankara inside a Balkan file where neutrality, Kosovo and alliance politics continue to collide rather than settle.
