Centurion: In the Valley of the God-Kings - Centurion Duology, #2

Ranger's team of Myrmidon cyborg super commandos have arrived in a desperate one-shot attempt to aid him in his battle against the Rochack invaders.  Joined by Sticks, Goober, Zira, and Rowlf, Ranger must now get his allies, including Kat, Edgar, and Sandy, ready for the next step in driving the Rochack off their homeworld: an attack on the Rochack's main base of operations.  The problem is that the Rochack base is in the middle of the Valley of the God-Kings, the holiest of holies belonging to the most fanatical terrorist cult in the world.  New allies will be needed if Ranger has any hope of saving Kat's homeworld from conquest.  Time is running out and further reinforcements may be too late.
