This history of the name of course does not reflect intent of alien life, but here is a short history of what gillie means from wikipedia:
The ghillie suit was allegedly developed by Scottish gamekeepers as a portable hunting blind. Lovat Scouts, a Scottish Highland regiment formed by the British Army during the Second Boer War, is the first known military unit to use ghillie suits. In 1916, Lovat Scouts went on to become the British Army’s first sniper unit.
