Guantanamo Bay Naval Base
U.S. and Cuban troops placed some 55,000 land mines across the "no man's land" around the perimeter of the naval base creating the second-largest minefield in the world, and the largest in the Western Hemisphere. On 16 May 1996, U.S. President Bill Clinton ordered the demining of the American field. They have since been replaced with motion and sound sensors to detect intruders on the base. The Cuban government has not removed its corresponding minefield outside the perimeter.
