A regional prison is opening at Fort Leavenworth, combining the operations of military prisons elsewhere in the United States. The Joint Regional Confinement Facility will be operated by the Army Corrections Command. It’s located on the northeast Kansas post near the U.S. Disciplinary Barracks, the military’s maximum-security prison. Dedication ceremonies were scheduled Tuesday for the prison and a new brigade that will staff it. The 464-bed facility will get its first prisoners next month from Fort Sill, Okla., and reach 120 inmates by January. In 2005, the Base Realignment and Closure Commission decided to close prisons at Fort Sill, Fort Knox, Ky., and Lackland Air Force Base, Texas.
