Serbia's 72nd Special Operations Brigade conducted a training exercise along the Drina River, which forms the international border between Serbia and Bosnia and Herzegovina. The exercise included river crossings and cliff rappelling drills performed in full combat gear. The US Ohio National Guard adjutant general observed the training alongside Serbia's chief of general staff on September 19, 2026. Local reporting and satellite imagery suggest forces operated directly at the border, with some accounts indicating units crossed into Bosnian territory during the exercise.
The Drina River has long served as a sensitive frontier between Serbia and Bosnia, with historical significance dating to the 1990s Balkans conflicts. Training exercises in this region carry symbolic weight in regional security discussions. The presence of a senior US National Guard official indicates continuation of the long-standing military partnership between the United States and Serbia, through which American armed forces regularly observe or participate in Serbian training activities. Such exercises may reflect Serbia's interest in demonstrating rapid-deployment and riverine assault capabilities to NATO and Western partners, though the stated purpose appears routine under existing bilateral defence cooperation frameworks.
