They came from the stars to reap the harvest of mankind. Who were they was unknown. The governments of the world formed covert cabals to deal with this deadly threat from the stars and now their back terrorizing the colonies of the Talon Sector! They're agenda is unknown but they leave swaths of destruction and empty corpses within their wake!
Beware the whirl of their ships for we are helpless against them!
According To Wiki:
The extraterrestrial spacecraft can readily cross the vast distances between their planet and Earth at many times the speed of light, but are too small to carry more than one or two crew members. Their time on station is limited: UFOs can only survive for a couple of days in Earth's atmosphere before they heat up, deteriorate and finally explode. The alien craft can survive for far longer underwater; one episode, "Reflections in the Water," deals with the discovery of a secret undersea alien base, which shows one UFO flying straight out of an extinct volcano, which Straker describes as "a back door to the Atlantic". A special underwater version of the standard UFO design is seen in "Sub Smash". In flight they are surrounded by horizontally spinning vanes and emit a distinctive pulsing electronic whine that sounds like a Shoooe-Wheeeh
The craft is armed with a laser-type weapon, but conventional explosive warheads can destroy it. The personal arms of the aliens resemble shiny assault rifles; these have a lower rate of fire than that used by SHADO. Later episodes such as "The Cat With Ten Lives" show the aliens using other weapons, such as a small device, which seemingly paralyses victims. This is presumably for organ and body harvesting purposes, since pilot Jim Regan's wife Jean is taken for her organs in that episode.

Aliens According To Wiki
The alien race is never given a proper name, either by themselves or by human beings; they are simply referred to as "the aliens". They are humanoid in appearance, and the autopsy of the first alien captured reveals that they are harvesting organs from the bodies of abducted humans. Their faces are stained green by the hue of a green oxygenated liquid, which is believed to cushion their lungs against the extreme acceleration of interstellar flight; this liquid is contained in their helmets. To protect their eyes the aliens wear opaque sclera contact lenses with small pinholes for vision
