Marine Corps Air Ground Combat Center Twentynine Palms

Marine Corps Air Ground Combat Center Twentynine Palms is a major United States military installation located in California, established as the largest Marine Corps base in the world spanning nearly 1,200 square miles. The facility serves as a Marine training center specializing in integrated combined arms live fire exercises and advanced warfighting experiments. The base gained significant attention in UAP/UFO research contexts following documented incidents in 1997 and April 2021, when multiple military witnesses reported sightings of unidentified aerial phenomena. The 2021 incident involved 50+ eyewitnesses observing a triangular craft and generated extensive video, photographic, and eyewitness documentation collected by investigative journalists. The base continues to operate as an active military training facility.
