Talk about being on the frontline: Command Sgt. Maj. Teresa King has become the first woman to take charge of the Army's drill-sergeant school. The 48-year-old is the daughter of a sharecropper and she’s a 28-year veteran of the military. Evidently, her father's stern discipline toward his 12 children encouraged King to take responsibility for herself and her siblings early on. A mere 14 percent of the service's 550,000 soldiers are female; King's storied assault on the military glass ceiling has broken more than the drill-sergeant barrier—she is also the first female sergeant to oversee what the Associated Press called "the heart and soul of Army warfighters," the 18th Airborne Corps at Fort Bragg, N.C.
