Area 51 The Nightstalkers Series by Bob Mayer

Born from the Area 51 initiative, the Nightstalkers defy sanity and decorum and include among their ranks Moms, a Black Ops trainee too extreme for Special Forces; Doc, a scientific crackpot; Roland, the weapons enthusiast; and Mac, a contemporary MacGyver. All of them take their orders from the elusive Ms. Jones, who everyone claims is just a hologram.
