Screenplays for the pilot were initially commissioned from at least two writers. Dusan Premovic submitted his draft in the Spring of 2010 and after his screenplay was rejected Dimitrije Vojnov was hired to pen his take. The draft written by Dimitrije Vojnov was used in initial negotiations with Serbian Army. However, eventually, Gordan Mihic was hired to pen the whole series. Upon completion Mihic was dissatisfied with the changes made by director Dejan Zecevic and the cast so he removed his name of the series and it was broadcast without screenplay with Mihic only credited as the creator of story.
