"This book investigates several aspects of military power and security in the North Atlantic and Arctic region. NATO's northern flank is a large maritime and littoral theatre, where NATO directly borders Russia's Northern Fleet Military Administrative Territory, which is the location of some of Russia's most potent air, sea, and land power capabilities. While military tensions on the northern flank had been relatively low for years, the Ukraine war and increased great-power rivalry have altered that dynamic, with heightened geopolitical tensions. This has increased the focus on military-strategic competition in this northernmost region of the alliance. This book presents new assessments of several aspects of military power and security in the North Atlantic and Arctic region. With an analysis of the security and political climate in the High North, and of developments in Western military strategies, capabilities, doctrines, and operational concepts, the volume seeks to bring together an holistic understanding of the strategic challenges and opportunities facing the North Atlantic states and NATO in this dynamic area of responsibility for the alliance. In doing this, the book provides key insights into the role of intelligence, as well as branch-specific and joint approaches to power-projection and operations in the High North, which also includes selected country case studies. This book will be of much interest to students of NATO, military studies, security studies and International Relations"--
