Firing at Civilian; Who is the Shooter?

An anonymous user recently uploaded the video to YouTube under the title “Happy Few Ordnance Symphony,” then quickly removed it.
U.S. commanders have launched an investigation into video footage that appears to show an American service member firing into the cab of a civilian truck as the two vehicles pass on a road in Afghanistan.

“The amateur video posted on a public website gives us serious concern,” the U.S. Central Command told POLITICO in a statement. “The video in question is not official, not authorized and does not represent the professionalism of the service members of U.S. Central Command.
“We are conducting an investigation into this video, and will take appropriate actions as a result of this investigation,” it added.

This action could have violated the military’s rules of engagement and may hamper the alliance with the Afghan government.
