The new data show a consistency among the installations handling the most sexual assault cases year-to-year, which include some of the military's largest posts.
In the report released on Friday, the Pentagon estimated that for the 2016 fiscal year, 32 percent of service members who experience sexual assault now report it, up from 25 percent in fiscal years 2014 and 2015.
"This kind of flexibility allows the department to better meet the department's goals to increase reporting of sexual assault and decrease the occurrence of the crime through prevention", he said. This means that the reports are referred for criminal investigation to either the Military Criminal Investigation Organization, or a civilian law enforcement agency.
The Department of Defense uses the term "sexual assault" when referring to penetrating crimes, sexual contact crimes and attempted sexual assault.
In fiscal 2016, there were 24 reports of sexual assault at the U.S.
That is an improvement over two years ago, the report said, when 15 percent or fewer of sexual assault victims in the military reported it.More news: Danica Patrick to end racing career at next year's Indy 500
"Sexual assault is fratricide in our formations, plain and simple".
The numbers reported on Friday reflect allegations by people of sexual assaults by people unrelated to them.
The Air Force Academy in Colorado had 44 reports, the highest for the Air Force.
The military has about 1.3 million active-duty troops. The newly released numbers cover the years 2013 through 2016.
Almost 500 sexual assaults were reported on San Diego Navy and Marine bases in 2016, according to numbers released Friday by the Department of Defense. Brown said some cases are decades old but any reporting victim has access to counseling and medical attention while the report is investigated. The database doesn't show what types of sexual assault were alleged or whether the victims were male or female, and the department notes that incidents reported didn't necessarily happen on the base.
For each of the military branches, as well as the joint bases and combat zones, the total number of reports in 2016 were largely identical to those in 2015. The incident could have occurred "while on deployment, while away on leave, or even prior to entering the military", the Pentagon said.
