Sigma Division is a branch of the National Security Agency which seeks out aliens, and their technology.
With the end of the Cold War, the NSA's budget was cut, and so, looking to find something else to excel in so that it would not eventually get absorbed into the U.S. Army, formed the Sigma Divison. This branch was to find and decipher highly advanced technology, not the kind invented by human beings, but by aliens. Finding such technology would give the NSA the necessary funding to continue its work, and since the Air Force had never found anything, earn greater respect.
