Over 1,000 records acquired by AP paint a “disturbing” picture of how allegations have been handled. The news agency said on Sunday that the process “verged on the chaotic.”
Reports of sex crimes filed between 2005 and 2013 showed that only one-third of 244 service members who warranted some form of punishment were incarcerated.
In 30 cases, a letter of reprimand was the only consequence of the allegation.
However, there were discrepancies between the different military branches, with inconsistencies apparent between how sex crime accusations were treated in the Marines and the Air Force.
The Marines sent 53 out of 270 sex offenders to prison, marking a sharp contrast with the number of jail sentences in the Navy - where only 15 out of 203 offenders were given jail time. Some 70 other Navy personnel received a court-martial or another form of punishment.
The Air Force only sent 21 out of 124 sex offenders to prison, making the military branch the most lax when it comes to issuing appropriate punishments.
Two specific cases were cited in the documents. Two service members overseen by the 1st Marine Aircraft Wing alleged they had been sexually abused after a night out. They had evidence to back their claims. One suspect was given six years behind bars, while the other was merely incarcerated at his base for 30 days.
AP also reported a decline in such cases over the time period studied, with a growing number of accusers dropping out of investigations. The agency suggested the data was symptomatic of a loss of confidence in the system for dealing with sexual assaults, or an unwillingness to speak with investigators.
“How many more rapes do we have to endure to wait and see what reforms are needed?” asked Senator Kirsten Gillibrand (D-NY), chair of the Senate Armed Services personnel subcommittee.
The number of sexual assault cases taken to courts-martial throughout the military has grown from 42 percent in 2009 to 68 percent in 2012, according to department data. However, this trend is not reflected in Japanese cases. Out of 473 allegations against sailors and Marines in Japan between 2005 and 2013, only 116 - 24 percent – ended up in courts-martial.
