A sweeping defense bill is headed to President Obama's desk.
Under the new legislation, US military commanders would no longer be allowed to overrule a court-martial judgment in sexual assault cases.
Congress acted after a report showed an increase in military sexual assault complaints.
The reform also includes a compromise to let the Pentagon transfer Guantanamo detainees.
The changes to military law were okayed by the House last week and by the Senate late Thursday.
The President is expected to sign the measure.
