The KFOR-soldier who drives the armored vehicle speaks Italian, but he is equipped with a French FAMAS assault rifle and drives a Serbian BOV (Bobreno Oklopno Vozilo). None of this makes sense, since the Italian army is equipped with Beretta assault rifles and doesn't use BOV armored vehicles.
During the most of the film, the main character (Serbian boy Nenad) wears a red T-shirt, apparently a Serbian national football team T-shirt (with a white cross on red background, a Serbian Football Association emblem on the left side in the front, and the name of a famous Serbian football player Dejan Stankovic and his no. 10 on the back). In 2004, when the plot takes place, Serbia was a part of the state union Serbia and Montenegro (until the split-up in 2006), and the color of the national football team T-shirt would have been blue, with the emblem of Serbia and Montenegro Football Association on the left side in the front.
