TEHRAN - An internal investigation into a U.S. Beret who fired a shotgun at a civilian truck driver in Afghanistan in early 2007 has revealed details that are likely to draw anger and outrage in Afghanistan.

Green Berets, The United States Army Special Forces, are a special operations force tasked with five primary missions.

According to the investigation, some soldiers in the U.S. Special Forces detachment in Afghanistan were shooting videos to promote their own clothing company, drinking alcohol on deployment and having extramarital affairs, which led to the incident in 2007.

Originally reported by Stars and Stripes, the details are contained in an U.S. Army investigation report. The report states that through unit interviews, investigators determined that the soldier fired a nonlethal bean bag round into the window of the driver’s truck after the driver failed to make way for the U.S. Army vehicle.

The incident came to light through a short video clip of a deployment montage posted online last year, leading to the investigation. The shooting happened near Bagram Airfield in Afghanistan, which is home to U.S. forces in Afghanistan’s capital.

The team’s captain told investigators that the driver had failed to heed other warnings and firing the round was the only way to get the driver’s attention. But the team’s operations sergeant called the shot “horribly poor judgement,” according to Stripes report.
