The House Armed Services Committee held a hearing Wednesday about sexual misconduct by basic training instructors at Lackland Air Force Base.
Thirty-two instructors were charged and there were as many as 59 victims.
Air Force officials said a key challenge to eradicating sexual assault was learning how to better connect with victims.
The Pentagon estimated that 19,000 sexual assaults occur every year among the armed services.
However, only a few thousand are ever reported.
