According to the newly released data, a collection of U.S. bases in South Korea had a combined 211 reports of sexual assault while Norfolk had 270 reports of sexual assault in the 2016 fiscal year, which began in October 2015 and ended in September 2016.
Unrestricted reports comprise sexual assault allegations that are referred to the Military Criminal Investigative Organization or law enforcement for investigation, while restricted reports are confidential, and are seen only by specific parties within the DoD, including its sexual assault prevention response team, and victim advocates.
"As a result, the number of reports listed for an installation doesn't necessarily mean that the alleged incident occurred there", Galbreath said in a press release.
The Department of Defense defines sexual assaults as adult sex-related crimes punishable under its Uniform Code of Military Justice.
The number of reports don't necessarily reflect the number of sexual assaults that occurred at a particular installation, however.
The Department of Defense provides numbers of sexual assault reports made by service members and their dependents as well as civilian employees at all US military installations.
Stamping out sexual assault in the military has been among the chief priorities for top Pentagon officials for years. Campbell spokesman in a statement.
In addition to Naval Station Norfolk, the Navy's largest base, the Army's Fort Hood in Texas, Joint Base San Antonio in Texas, Joint Base Lewis-McChord in Washington, Naval Base San Diego, and the Marine Corps' Camp Lejeune in North Carolina and Camp Pendleton in California have regularly received the highest tally of sexual assault reports in recent years.
Considerably fewer were filed in the Navy and Marine Corps who recorded 4,788 and 3,400 respectively. Then there was a slight decline previous year to 114.
Previously, during the 2014 fiscal year, SAPRO estimated that only 14 percent of military victims were reporting.
The military has about 1.3 million active-duty troops.
The DOD on Friday released the numbers for installations, and combat areas of interest, around the world in the last four fiscal years.
At any point in time, a DoD victim may choose to change their filed restricted report to an unrestricted report. They include active-duty service members, activated Reserve and National Guard troops and civilians who allege assaults by active-duty military personnel. That number jumps up to 59 in 2015 and 44 in 2016.
