Marine Barracks Guantanamo Bay, Cuba

Marine Barracks Guantanamo Bay, Cuba, was established in 1898 following the U.S. seizure of Guantanamo Bay during the Spanish-American War. The unit’s primary mission has been the security and defense of the U.S. Naval Base at Guantanamo, making it one of the oldest continuously operating overseas Marine posts. Over the years, Marines stationed there have played key roles in base security, crisis response, and regional stability, particularly during periods of heightened tension such as the Cuban Missile Crisis. Today, Marine Barracks Guantanamo Bay continues to provide vital security and support functions for the naval installation.
