The First World War led not only to social revolutions throughout Europe, but also to a revolutionary upheaval in military affairs. And we’re not just talking about military aircraft, tanks, gases, etc. — during the war, even the oldest branch of the military, the infantry, was radically transformed: fundamentally new weapons and defense systems were added to the traditional rifle and bayonet, tactics and communications, supply and control, combat training and methods of interaction of troops, their appearance and front-line life changed dramatically . And yet, despite all the innovations and changes, the main thing remained unchanged - the role of the infantry on the battlefield: the outcome of battles, operations and entire campaigns still depended on it, it was on its shoulders that the main burden of combat operations fell, namely. the infantry suffered the most terrible losses, remaining the “cannon fodder” of the war. The new book by the leading weapons historian is the best to date, the most complete and detailed study of the combat use of Russian infantry on all fronts of the First World War, unprecedented in the scope of material and depth of analysis.
