Because Serbs are too stupid to put bullets in one at a time, or because they are too clumsy to operate the trigger so as to only fire one round at a time?
You're out of your depth here, Kosta.
Furthermore, this isn't about single shot operation, it's about effectively hitting a target over long distances using an automatic weapon, which, in this particular case corresponds to civilians in Sarajevo being targeted by machine guns on the hills surrounding it.
Hoplite, maybe your delicate fingers can touch an M-16 trigger set on automatic and fire a single round. That will be the day. The weapon in question was desinged for 10-round bursts minimum, 25 maximum.
Single bullet is an option, but that's not what your "sniper" pictures shows. It shows a machine gun on a tripod that has a tailstock and is obviously not a .50 cal as you and some others claimed, and a whole bunch of ammo attached to it. The clip shows Radovan firing indiscriminantly on buildings which appear but are not necessarily empty. I didn't see any evidence that he was aiming at any civilians. I have already said that his firing in the direction of the city was reprehensible.
What seems to be the disagreement? The fact that you called someone a sniper when it was not a sniper, or that you mistook a 7.62 mm machine gun for a .50 cal?
Again, civilians were targetted on both sides. Not all people targetted were civilians. Is there a problem with that? Or are you simply denying that the Muslim side ever did anything wrong?
