Bolos: Their Finest Hour — Keith Laumer

Controlled by their tireless electronic brains which were programmed to admit no possibility of defeat, the gigantic robot tanks known as Bolos were almost indestructible, and nearly unstoppable. Their artificial intelligences were designed to make them selflessly serve and protect humans throughout the galaxy and made each Bolo the epitome of the knight sans peur et sans reproche, and often far more noble than the humans who gave them their orders.

Created by Keith Laumer, the saga of the Bolos has been extended by several of the best writers in science fiction. Now, the best stories of the saga are collected in one Omni-Trade volume, including work by New York Times best-selling writers David Weber, Mercedes Lackey and S. M. Stirling, military science fiction grand master David Drake, and Laumer himself, who recount the exploits of the dauntless Bolos in Their Finest Hour.
