The U.S. Disciplinary Barracks (USDB) is the military's only maximum-security prison, located at Fort Leavenworth, Kansas. It is operated by the United States Army and houses service members who have been convicted of serious offenses, including violent crimes and drug offenses. The facility is designed to maintain strict security and discipline among its inmates. In addition to housing military prisoners, the USDB also provides rehabilitation programs aimed at reducing recidivism. Inmates may participate in educational and vocational training, which can help them reintegrate into society after serving their sentences. The USDB plays a crucial role in the military justice system.
