Washington ? Women at U.S. military academies say they have faced 302 incidents of sexual assault since they enrolled, a figure the military says is comparable to civilian schools.

“We are about where college campuses are, tragically. That’s not, frankly, terribly surprising,” said David Chu, undersecretary of defense for personnel and readiness.

He announced on Friday the results of the Pentagon’s first comprehensive study of assaults at the Army, Navy and Air Force academies.

Of the incidents, about a third — or 96 — were reported to authorities.

About 97 percent of women at the academies — 1,906 — responded to the survey. Because of the large number of men at the academies, surveyors used a random statistical sample of 30 percent of the men — or 3,107 — evenly distributed and represented across the academies.

Over 50 percent of female respondents and 11 percent of male respondents indicated experiencing some type of sexual harassment since entering the schools, the executive summary said.
