The Mammoth Book of SF Wars — Ian Watson

Over the past 100 years the technology of war has advanced enormously in destructive power. So what will future wars be like? And what will cause them: religion, politics, resources, refugees, or advanced weaponry itself? Watson and Whates present a collection of gripping SF stories which explores a daunting gamut of possible future conflicts: nuclear tactics and enhanced soldiery, terrorism and cyberware, intelligent robotic machines and even war with aliens.
