"Even a terminally damaged Bolo is still an opponent to reckon with, and as long as a Bolo's artificial intelligence retains a flicker of consciousness, its indomitable drive to defend the human race against all enemies will propel it forward. Bolos can be destroyed--but they never surrender!"
"The Unconquerable continues the amplified history of the Bolo--an almost indestructible, nearly unstoppable tank controlled by a sophisticated artificial intelligence. These stories by S.M. Stirling, William R. Forstchen, Christopher Stasheff, Shirley Meier, Todd Johnson and more tell of the faithful and tireless protectors of the human race: the Bolos."
"The future of war--and the fate of man--lies with one machine: the Bolo. With plated armor, a laser cannon, an electronic brain, and wheels, it defends humanity from aliens that threaten the entire species. Now comes the amplified history of the Bolo in stories by David Drake, S.M. Stirling, Mercedes Lackey and others."
