A former U.S. Marine who served from 1968 to 1969 at the U.S. Guantanamo Bay Naval Base in Cuba has reported Marines’ experience of UFO activity during the time he was on duty at the base. He said he witnessed UFOs landing in the ocean and taking off from the ocean, indicating there was a major alien UFO underwater base in the bay.

The Marine’s testimony was filed as Case 74794 in the archives of the Mutual UFO Network (MUFON), the largest single UFO sightings documenting and investigating organization in the world.

According to the Marine, who was often assigned to guard the fence area of the facility, he and other Marines were perplexed by the heavy UFO traffic over and around the base. He said UFOs were seen flying over the base almost every night and many flew at altitudes below 300 feet.

MUFON Report

“All of us Marines were amazed at the amount of UFO activity over and around this base,” he told MUFON investigators. “Virtually every night UFOs were flying overhead with altitudes of less than 300 feet.”

The witness said he saw several UFOs flying overhead because he often stood guard at the south fence of the base. And because they passed over the base at relatively low altitude, he was able to determine that most were about 50 feet to 100 feet across.

They were not brightly colored, but mostly plain-looking with dull colors. He also often saw red lights trailing the UFOs as they flew overhead.

An intriguing observation he made was that many of the UFOs flew towards the ocean, and there was a steady flow of UFOs landing and taking off from the ocean.
