Goran was a soldier in the Bosnian War and a member of the same fifteen man squad as Niko Bellic, Florian Cravic, Darko Brevic, Mijo, Dragan and Dmitar. During the mission That Special Someone, Darko mentions that "Goran and his guys" had killed Darko's neighbours. This could have been a supporting factor to his eventual betrayal to the squad.
