Sgt. Justin Boyle is scheduled to be court-martialed for involuntary manslaughter and other charges. He faces a maximum of 10 years in prison if convicted.
Testimony in January revealed that soldiers from Brown's unit tried to restrain him by punching him and tying his hands. The soldier reportedly had become unruly after a night of drinking at a Fayetteville bar.
The soldiers said when they drove back to the barracks, Brown was unresponsive.
Military officials have not decided whether the other six soldiers will stand trial.
