Members of the U.S. military stationed in Japan are receiving almost no punishment for committing sexual assault, according to a new trove of Department of Defense documents revealed by the Associated Press Monday.

More than 1,000 records, obtained by the AP through a Freedom of Information Act request, reveal that military personnel accused of sex crimes were often not given jail time and instead received “light punishments” such as fines, demotions, restrictions to their bases or removal from the military.

According to AP, in about 30 cases a letter of reprimand was the only punishment.

The victims of these crimes include other military personnel as well as civilians living near the U.S. bases in Japan. The documents further reveal that a growing number of the victims of sexual assault are “dropping out of investigations” by either retracting the allegations or declining to cooperate further.
