Good question ceridwen. However, most of the contactees that I've had personal conversations with were not associated with the military. Those who are involved with the military tend to be associated with the Secret Government and some negative ETs. Not all off-worlders who visit or live on this planet are negative (against Humanity). The military tends to track what is going on with off-worlders visitors and when they make contact, they tend to show up afterwards abducting these people to interrogate them (want to know what ET info they have), alter their memories by replacing them with negative Et memories. This seems to occur more in the US. Of course there is a big difference between a contactee and abductee as there are differences between the different types of off-world contact.
You may enjoy reading Sean David Morton's book "Sands of Time" which is excellent. He also did a sequel that we just purchased from Amazon.com
An Epic story spanning over forty years in the life of Dr. Ted Humphrey and his involvement with Area 51, The Dulce Mesa Wars, The Montauk Project, Black ops, The shadow Government, and his meteoric rise to become head of an all powerful global organization engaged in a desperate and above top secret race against time to save our world. Beginning at the age of 17 when his father, a brilliant scientist with a mysterious past, disappears. Ted makes it his life's quest to discover his father's fate. This leads to him being drafted into a series of high-level government projects working on the most valuable piece of research equipment ever built...a machine that can move objects through SPACE and TIME. As Time Technology is developed, Ted is inexorably drawn into a world-wide web of mystery, intrigue, disinformation and power. He is taken inside an elite, clandestine group of men dedicated to hiding the truth from everyone outside a small tight-knit cabal of politicians, scientists and spooks; that forces from beyond the stars could lead to Earth's destruction at some point after the galactic alignments of 2012. In a world where one mistake could be your last, Ted gets guidance from people further down and outside of the time stream, never knowing who he can trust, while still seeking to solve his father's disappearance. SANDS OF TIME is truly remarkable. A rare and precious look behind the curtain of Covert Ops into the Black World of super-technology with enough hard science to convince even the most cynical skeptic. It solves so many of the mysteries that have baffled researchers since the Roswell crash in 1947, and shows us, once again, that all we have come to accept as reality, is wrong.
