UFO's in Iraq

This is a very well-documented sighting, taken by American soldiers in Iraq. My first thought was that they could be flares, or rockets launching, but they stand still in the sky for the whole two minutes of the film. They also make no audible sound at all whereas rockets are one of the noisiest things on Earth. The film was taken through a night-vision camera and I wonder how bright the objects would be without it. However, they're obviously bright enough for the witnesses to make note of them; they sound very surprised. One of them denies immediately that the objects are stars or planets distorted by the cloud.
