A retired US Marine has revealed that he has allegedly served 17 years at a secret alien base on 'Mars' in order to protect five human colonies from indigenous Martian life forms.

The ex-naval infantryman, who uses the pseudonym Captain Kaye, released a testimony to ExoNews TV stating that he was trained to fly three different types of space fighters and three bombers, the Mirror reported. The retired officer further added that training took place on a secret moon base called Lunar Operations Command, Saturn's moon Titan, and in deep space.

Captain Kaye has also claimed that he had nearly spent three years serving in a secret 'space fleet' that is run by a multinational organisation called the Earth Defense Force, which recruits military personnel from countries including the US, Russia and China.

Moreover, he also described his retirement ceremony on the moon after 20 years of service, which he asserts was presided over by VIPs including ex-Defense Secretary Donald Rumsfeld.
