A Pentagon health survey released yesterday says about one out of five military women say they were victims of unwanted sexual contact by another service members since joining the military. The highest rate of sexual abuse was in the Marine Corps: Nearly 30 percent of women said they suffered unwanted sexual contact by another military member. Close behind were the Army and Navy, each with about 24 percent of women raising the issue. The sexual abuse rates from the 2011 survey are significantly higher than similar findings from 2008, when 11 to 12 percent of female soldiers and sailors said they were victims of unwanted touching, along with 17 percent of women who were Marines.
