Military comparisons between Croatia and Serbia highlight divergent defense strategies in the Balkans. Croatia, a NATO member, maintains a smaller, technologically integrated force of approximately 15,000–20,000 active personnel, focusing on interoperability and high-precision artillery. In contrast, Serbia maintains a policy of military neutrality with a larger force of roughly 30,000–32,000 active troops and a significant numerical advantage in main battle tanks and armored vehicles.

During an annual conference for diplomats and military attachés in Zagreb, Croatian officials intensified warnings regarding Serbian military developments. Parliament Speaker Gordan Jandroković and Defense Minister Ivan Anušić called for Western allies to be informed of Serbia’s rapid modernization, arguing that Belgrade is acquiring “not only defensive but also offensive weaponry.” Jandroković noted that Western political elites might lack the historical context of the former Yugoslavia necessary to grasp current regional security risks, and he advocated for strengthening the European pillar of NATO.

In response to these alarms, Serbian President Aleksandar Vučić dismissed the claims with irony, stating that Serbia’s military buildup is intended for deterrence against potential aggression rather than for war. He criticized Croatia’s own acquisitions, such as German Panzer 2000 howitzers, as being equally significant. Military analyst Marinko Ogorec has warned of a potential regional arms race, noting that certain Serbian systems, such as Chinese hypersonic missiles, could reach much of Croatian territory.

To bolster its own security, Croatia is implementing a modernization plan intended for completion by 2030. Defense Minister Anušić highlighted that Croatia has increased its military training capacity to 1,000 recruits per cohort while working to expand its domestic defense industry.
