This book seeks to contribute to the academic and professional discourse on military law by offering a detailed and nuanced comparison of these three legal systems. It is intended to serve as a resource for legal professionals, scholars, and policymakers engaged in the study or practice of military law. By highlighting both the commonalities and the unique aspects of military jurisprudence in these nations, I aim to provide a richer understanding of how military law functions and evolves in different geopolitical contexts.
