I'd say he was definitely from a former Yugoslav country as it is mentioned that he fought in the Bosnian War. I also read something along the lines of "if your village was under attack do you run or fight?". This would suggest he is of the race being opressed, which would therefore make him bosniak. If he is a bosniak however he would most likely be muslim which i doubt he is. I don't think there is enough evidence to say which race is is from as Rockstar have deliberately avoided any racial tensions between FYR countries.
