This text was extremely helpful to me on a subject that is little covered in English. Osprey is usually not that comprehensive but this book although condensed hit the salient points of the Russian army in the field in the First World War. I like the introduction and strategic overview, insightful and well written. The chronology of events with dates given to the major actions on the eastern front of the First World War was excellent, they also explored Russian military tactics and doctrines, easy to use research tool and quick reference. Although brief the author went into non-Russian units used at the front, vehicles and aircraft, even equipment and uniforms The photographs were excellent, I love the detailed color plates featuring many different uniforms, helmets and other varied headgear as well as the equipment used by the common soldier. I would recommend this book to anyone who is a student of military history and has an interest of the eastern front in the First World War.
