Joint Task Force Guantanamo (JTF-GTMO) is a U.S. military joint task force based at Guantanamo Bay Naval Base, Guantánamo Bay, Cuba on the southeastern end of the island. JTF-GTMO falls under US Southern Command. Since January 2002 the command has operated the Guantanamo Bay detention camps Camp X-Ray and its successors Camp Delta, Camp V, and Camp Echo, where detained prisoners are held who have been captured in the war in Afghanistan and elsewhere since the September 11, 2001 attacks. The unit is currently under the command of Rear Admiral David B. Woods, who replaced Rear Admiral Jeffrey Harbeson in August 2011. Previous commanders have included Army Major General Geoffrey D. Miller, who took command in November 2002.
In 1992, the United States established Operation Sea Signal to prepare for a mass migration of refugees from Haiti and Cuba. In 1994, Operation Sea Signal led to the creation of Joint Task Force 160. JTF 160 was responsible for housing and processing more than 40,000 migrants awaiting repatriation or parole to the United States. Camp X-Ray was established to segregate migrants who had committed crimes, such as theft, assault and battery, prostitution and black-market activities, from other migrants and from U.S. civilians and military personnel at Guantanamo. In 1996, Operation Sea Signal came to an end and the military abandoned Camp X-Ray.
