Brute force. Intransigent defiance. Adamantine will.

These are the hallmarks of the AI tank. Formed from cold steel and superpowered computing brains, these gigantic tanks with the firepower of an entire army have been the decisive factors in interplanetary battle. But are humans worthy of the extraordinary instruments of war that they have created? Are the world breakers the greatest protector of human liberty, or its worst threat? For, while these world breakers very definitely have minds of their own, the question remains: within their iron and superluminal quantum breasts, does there lie a faithful heart? Stories of world breakers and world makers in the great tradition of Keith Laumer's Bolos from David Weber, Larry Correia, Wen Spencer, and more!

About World Breakers:
"'Dyma Fi'n Sefyll' by David Weber may be the finest MilSF short story I have ever read in the fifty-seven years I have been reading science fiction. It alone is worth the price of the book."--Tangent

About Star Destroyers, edited by Tony Daniel & Christopher Ruocchio:
". . . spectacular space battles and alien contacts . . . themes of military ethics, the uses of artificial intelligence, and the limits of the capacity of the human mind. . . . it is the human interactions and decisions that ultimately drive the stories. . . . will appeal to fans of military and hard science fiction and any readers fascinated by the possibilities of space travel."--Booklist

". . . stories of giant spaceships at war, at peace, and in the often-gray areas between. . . . a worthy addition to a long tradition of ship-based fiction, and its authors portray captains, arcane astrogators, and civilian child passengers with equal depth. It's recommended for fans of military SF and space adventure."--Publishers Weekly

". . . you'd probably expect some tight, action-filled space opera stories of giant space battles . . . and there's some of that. But there are also espionage stories, rescue missions, political conflicts, alternate histories, even a few humorous tales. . . . each author took the premise in a different direction . . . if I had to identify one common feature to all the stories, it would be that they're all fun. . . . Like it says, big ships blowing things up. What's not to like?"--Analog
