The US Navy is asking sailors, Marines, and civilians working for the military branch to complete a survey on sexual harassment, which has been ongoing and wraps up today. The confidential survey, which allows respondents to complete it anonymously, is being administered by the Department of the Navy’s Sexual Assault Prevention and Response Office.

Past studies indicate that approximately one percent of women in the Navy are raped each year, and another three to four percent experience some form of sexual assault. Most crimes are committed against junior-level female sailors, though men are also reported as victims of some sex crimes.

“The survey responses will help us gauge our progress and serve to guide our program adjustments for increased effectiveness at combating sexual assault department-wide,” said Rear Admiral Martha Herb, director of the Personal Readiness and Community Support Branch, in a news release by the Navy.
