A Serbian soldier peers out of the window of an urban-combat facility while providing security for the combined-forces convoy of Serbian and Bulgarian troops during a cordon, search and seizure training exercise supervised by U.S. Marines of Black Sea Rotational Force 11. The Black Sea Marines conducted training with partner nations in counterinsurgency and peacekeeping operations with the Bulgarian 38th Infantry Battalion, 2nd Light Infantry Brigade, and the Serbian 21st Mechanized Infantry Battalion, 2nd Brigade, to build the military capacity of partner and allied nations in the Black Sea, Balkan and Caucasus regions. The Bulgarian unit is scheduled to deploy to the Kabul province of Afghanistan this summer while the Serbian unit is scheduled to deploy to Cyprus in the near future. The training was conducted in Novo Selo's 55-square-mile training area that features designated ranges for machine guns, RPGs and combat marksmanship, vast land for patrolling and convoy operations, and dedicated urban combat environments for training in military operations in urban terrain and cordon, search, and seizure.
