Already reeling from an embarrassing sex scandal involving former Army General David Petraeus, the U.S. military on Wednesday will release a report on widespread sexual abuse of women recruits at Lackland Air Force Base in Texas. The Air Force report is expected to provide details of systematic sexual abuse in the U.S. Air Force, a scandal that until last week was considered the worst in the military in more than a decade. But the disclosures of harassment and abuse at the Air Force base have been overshadowed by the abrupt resignation of Petraeus. The former commander of U.S. forces in Iraq and Afghanistan stepped down from his post as CIA director last week after admitting to an extramarital affair with a female biographer. The report on Wednesday will detail problems at Lackland, where all U.S. Air Force basic training is conducted. Eleven basic training instructors have been charged with offenses ranging from inappropriate touching of female recruits to sexual assault.
