Factual error: In the first scene when Kyle is doing over-watch for dismounted infantry, an Iraqi is shot and his body falls from the rooftop, startling a soldier. The report is heard first, the a hiss of the incoming shot. It was cool that they tried to make the hiss, but it should have been first, as the bullet is supersonic, and arrives before the report of the gun is heard. Pretty egregious error for a sniper film.
