A war that moves at machine speed changes more than tactics; it changes who gets to decide, and when. This book explains how algorithmic warfare compresses decisions, why predictive targeting raises new accountability burdens, and where autonomous command can fracture alliances or steady them. It is a field manual for readers who want clarity over spectacle.You will learn how capability stacks work in practice: data pipelines, models, and compute chokepoints that shape AI in defence. You will see how cyber sovereignty turns clouds and cables into contested terrain, why tech militarisation is as much about procurement and training as it is about code, and how global AI treaties might evolve from bans to baselines. Above all, you will gain a way to test claims, weigh trade-offs, and recognise when speed is masking risk.Written for policy leaders, defence professionals, technologists, and informed citizens tracking superpower competition, it offers durable concepts, practical checklists, and sober scenarios. If you care about military AI ethics and the realities of the geopolitical AI race, this is a clear-eyed guide to what matters and what merely makes noise.
