A number of United States Army drill sergeants at Fort Benning in Georgia have been suspended amid an investigation into sexual misconduct, the Army said in a statement on Wednesday.

The investigation began after a female trainee at the fort recently leveled assault allegations against a drill sergeant there. That led to a review that “revealed indications of additional allegations of sexual misconduct involving trainees and drill sergeants,” the Army said.

“Our initial actions are to ensure the safety and welfare of all of our Soldiers,” the statement said. “The drill sergeants have been suspended from drill sergeant duties, and will have no contact with trainees during the course of the investigation.”

Ben Garrett, a spokesman for Fort Benning, would not disclose how many sergeants had been suspended because the investigation, led by the United States Army Criminal Investigation Command and Fort Benning’s Maneuver Center of Excellence, is underway.
