In Part Two of this Lives in Leadership conversation, Major General Andrew Hocking joins Dr Lucas Marie to discuss organisational learning, national preparedness, and the role of social science in Defence. Drawing on his Vanguard paper, Preparing for the Future: Key Organisational Lessons from the Afghanistan Campaign, Major General Hocking reflects on the courage it takes for institutions to learn openly — and the political, cultural, and structural barriers that often get in the way. He explains how Defence must move beyond isolated, “whole-of-government” thinking to embrace a whole-of-nation approach, in which collaboration across the public, private, and community sectors strengthens Australia’s resilience in times of crisis. The discussion also highlights the value of diverse perspectives — including anthropologists and other social scientists — in understanding human behaviour and improving operational strategy. Hocking argues that meaningful learning and effective leadership depend on embracing tension, humility, and open dialogue across disciplines.

In this episode of Lives in Leadership, Dr Lucas Marie sits down with Dr Florence Gaub — Director of the Research Division at the NATO Defense College, futurist, and global security thinker — to explore the intersection of technology, strategy, and human judgment in defence. Dr Gaub challenges the idea that artificial intelligence is a true revolution in warfare, arguing instead that conflict remains a deeply human enterprise defined by continuity, emotion, and bias. She offers insight into the practice of strategic foresight, explaining how NATO uses “weak signals” and scenario-building to anticipate future risks. The discussion ranges from the cultural and historical roots of strategic identity to global recruitment trends and the myths surrounding younger generations’ “will to fight.” Drawing on NATO research, Dr Gaub presents a compelling, optimistic view of modern military society — one grounded in adaptability, understanding, and purpose.

The 16th and 17th century was a period of significant change in the character of war. The drivers accounting for these changes were not all based in military reforms, despite Western Europe being engaged almost continuously in war. While tactical applications is interesting, it was the beginnings of some profound changes in the development of warfare; the professional military, the standing army, scale of warfare and subsequent emergence of the state (Crown) owning the monopoly on violence and the arrival of proper naval forces.
