Around two and a half years ago, a well-publicized sexual-assault scandal rocked the Air Force's basic training program in San Antonio. Nearly 70 people came forward to accuse more than 30 training instructors of offenses including unwanted touching, inappropriate relationships, and rape. General Mark Welsh, the Air Force chief of staff, described sexual assault as a "cancer" infecting the culture of the base. In the wake of the scandal, the Air Force set up 24-hour hotlines in dorms, launched leadership training for basic training instructors, increased the number of female training instructors, and implemented dozens of other changes.
