Small Unit Tactics
Lost to the reader who is not a military professional is the true meaning of strategy, operations, tactics and other critical concepts. English's On Infantry, together with his entire series, are important for professionals and non professionals alike. Why? Simply because they explain not just the current theory or philosophy for the subject at hand?they go beyond that. History without context is not very useful. On Infantry creates a context for the Infantry by introducing enough history to show its evolution and create the context necessary to understand the modern Infantry and why it behaves as it does requires reading this book.
