This book builds on the six years of hands-on experience that the author had while working in the North Atlantic Treaty Organization. It provides an overview and history of NATO, looks at the political and military components of the Alliance, as well as the military command from the perspective of real-world contemporary NATO operations and planning. The author also looks at the military training, lessons, and exercise components and how it prepares forces to support upcoming NATO Response Force (NRF) rotations to ensure that NATO is a viable threat deterrent and responsive organization to both Article 5 and non-Article 5 operations. This book will serve as a primer into the world’s longest enduring Alliance and one that has made an impact on real world operations over the last 20 years in Europe (Bosnia and Kosovo), Africa (Libya), Asia (Afghanistan and Pakistan), and the Middle East (Iraq).
