Staff Sgt. Herman Gunter has become part of the fifth military trial this year to arise from an Army inquiry regarding sexual misconduct at Aberdeen Proving Ground, the training center northeast of Baltimore. On August 14, a military court dropped two allegations against the drill sergeant for “sexual intercourse by fear,” a charge similar to rape, and permitted his court-martial on assault and adultery. Army prosecutors refrained from explaining the dismissal of the more serious charges. They also offered no reasons for dropping accusations from one of the three trainees. Gunter faces eight remaining charges, including one count of assault, cruelty and maltreatment.
