Investigation of assault by soldier who threatened to kill Iraqi civilians in custody of U.S. forces in an army compound in Baghdad, Iraq. The soldier forced a detainee to hold a round in his hands, threatening to kill him with it if he did not provide information regarding a recent grenade attack. At one point, the soldier ordered two detainees down on their knees with their eyes closed and a bullet in their mouths. He took the bullets and ordered another soldier to charge his gun without chambering a round. The two detainees separately identified the same individual allegedly responsible for the grenade attack, making the soldier leading the interrogation to "feel that [his] tactics worked." The soldier admitted to having no formal training as an interrogator and was not aware of formal army policies on interrogation techniques. He said that he had no intent to injury any detainee and claimed that no one touched or pointed a weapon at anyone. Though the investigation found probable cause to believe that the soldier had committed assault, the investigation was terminated and nonjudicial action was taken pursuant to UCMJ Art. 15.
