This book gives readers a clear understanding of the military character dynamics of both wars and how these changed between 2001 and 2014. This includes the strategy, operations, tactics and technology of the forces of the US and its allies, Afghan and Iraqi government forces as well as insurgents and militias, showing how they evolved over time. Many of these developments have wider relevance to future conflicts. The book identifies those that are of potential wider application to US, NATO and other western forces, to insurgents, as well as to forces of states that might choose to confront the west militarily.
