Professor Emeritus David Horner AM FASSA is one of Australia’s greatest military historians and its fifth official historian of war and military operations. Few who undertake research in the field can do so without consulting his prodigious, authoritative and definitive publications. Serving for 25 years in the Australian Army before joining The Australian National University, Horner is the epitome of the soldier–scholar and has played a key role in establishing military history as an academic discipline in Australia.

This volume explores the impact of technology and new domains on future warfare. It identifies several themes, and highlights the increasing complexity of the security environment and the uncertainty of future war. The sense of time and speed has been, and is being, compressed by developments in quantum technologies, the cyber domain, artificial intelligence, the increased capabilities of sensors and data collection, as well as new propulsion technologies such as hypersonic designs.

The norms of everyday life were often cast aside during the pandemic years. States shut their borders, mothballed their economies, and locked down their cities. Individuals put family life, career goals, travel plans – even medical treatments – on hold. In Australia, a Government elected on a platform of neo-libertarian freedom and debt reduction, spent like Keynesians while curtailing even basic freedoms. Some citizens protested but most accepted curfews, mask mandates and the shuttering of schools and workplaces in exchange for the promise of safety.
