The Aberdeen Scandal was a military sexual assault scandal in 1996 at Aberdeen Proving Ground, a United States Army base in Maryland.
Ultimately, twelve drill instructors were charged with sex crimes; four were sentenced to prison, while eight others were discharged or received non-judicial punishment.[1] Additionally, “letters of reprimand were issued to Aberdeen’s commanding general and three other senior officers.”[1]
