Army has always been faced with the questions of what type of war it should aim to prepare for, and in what context it should prepare. Mobilising the Australian Army explores the rich history of the Australian Army, the challenges of preparing armies for war in uncertain times, and the many possibilities for their continuing strength and future success. Comprising research presented at the 2021 Chief of Army History Conference, this collection examines how contingency and compromise are crucial elements for both the historical and the modern-day Army. Key themes include the mobilisation of resources for war in the first half of the twentieth century, the employment of women in the war effort at a time of rapid force expansion, alliance and concurrency pressures in the Cold War and post–Cold War years, utilisation in crisis and war of the reserve forces, and deployment challenges in the 1990s and beyond. Written by leading Australian and international military historians and practitioners, Mobilising the Australian Army will appeal to both casual history enthusiasts and future Army.
