The UNSC Maximum Security Detention Facility was a supermax prison run by the United Nations Space Command. The prison is joint-headed by the ONI Security and Reconnaissance Agency, for security and surveillance reasons, and the Unified Earth Government. All visits to inmates/detainees are non-contact. Inmates/detainees and visitors are separated by a glass window and communicate by use of a phone. Visits are one hour long. Any inmate that is violent or displays aggressive contact is subjected to cryo sleep, until the death sentence or their prison release.
