Camp X-Ray, initially used as a holding area for unruly migrants in the late 1980's and 1990's, was used as the first detention facility for alleged terrorists after Sept. 11, 2001. Camp X-Ray was used for only four months until Camp Delta was established providing better shelter for enemy combatants detained by Joint Task Force Guantanamo. JTF Guantanamo conducts safe, humane, legal and transparent care and custody of detained enemy combatants, including those convicted by military commission and those ordered released. The JTF conducts intelligence collection, analysis and dissemination for the protection of detainees and personnel working in JTF Guantanamo facilities and in support of the Global War on Terror. JTF Guantanamo provides support to the Office of Military Commissions, to law enforcement and to war crimes investigations. The JTF conducts planning for and, on order, responds to Caribbean mass migration operations.
