Dejan Berić

In March 2021, Berić announced that he is returning to the front lines due to the increased tensions between Ukraine and Russia.

Prior to the 2014 Winter Olympics, Berić worked in Sochi on constructing the Olympic Village. Following the Olympics, Berić was recruited by Russian special services, left for Crimea and participated in its subsequent annexation by Russia. For this he was awarded the For the Return of Crimea medal.

After the War in Donbas started, Berić travelled to Ukraine through Sevastopol and joined the forces of the self-proclaimed Donetsk People's Republic as a sniper. According to the Ukrainian government, Berić was a mercenary leader of a sniper squad that has sought to kill members of the Armed Forces of Ukraine at the line of separation. Berić received several decorations from the Donetsk People's Republic for his war merits, such as for killing Ukrainian snipers and shooting down spy drones. He was captured in July 2014 on the road between Lugansk and the Russian-Ukrainian border. His freedom was paid for, so he continued to fight. It was reported that he was wounded in combat in 2018.
