A former US Marine has claimed he spent 17 years of his career on MARS. The ex-naval infantryman, who uses the pseudonym Captain Kaye, says he was posted to the Red Planet to protect five human colonies from indigenous Martian life forms. He claims he then spent nearly three years serving in a secret 'space fleet' run by a multinational organisation called the Earth Defense Force, which recruits military personnel from countries including the US, Russia and China. In testimony released to ExoNews TV, Captain Kaye said he was trained to fly three different types of space fighters and three bombers. He added that training took place on a secret moon base called Lunar Operations Command, Saturn’s moon Titan, and in deep space. Captain Kaye says he retired after a 20 year tour of duty, describing a retirement ceremony on the moon that he claims was presided over by VIPs including ex-Defense Secretary Donald Rumsfeld.
