Sustaining Resilient Military Training in the Multi-Domain Era: Challenges and Opportunities

The rapid evolution of warfare in the modern multi-domain battlespace necessitates a corresponding transformation in military training and education. The 21st-century battlefield is increasingly complex, with technology and the operational environment changing at an unprecedented pace across all domains--land, air, sea, cyber, and space--while major opponents of Western alliances continue to strengthen and coordinate their economic and military power to challenge the international order. The ongoing Russian war in Ukraine starkly illustrates the dynamic challenges of the modern battlespace and underscores the need for military instruction systems that are both resilient and adaptable. This article explores the "train while we fight" concept as a paradigm for addressing the challenges and opportunities in military education and training, emphasizing that learning must be continuous, adaptive, and integrated into operational activities. We analyze the growing role of Advanced Distributed Learning in education and training, highlight the need for multinational cooperation to build and sustain training resilience, and examine innovative instructional approaches inspired by fields such as lean manufacturing, mass customization, personalized learning, and on-demand content production.
