The present issue of the arch "Old Russian Weapons" is a continuation of the first two books of the same author, namely issue 1 - "Swords and Sabers, IX-XIII centuries" - and issue 2 - "Spears, streets, battle axes, maces, brushes, IX-XIII centuries." The issue consists of three sections. The first considers such a bright and indicative part of weapons as armor. Sorting and classification of things was not an end in itself, but served the tasks of historical and military-tactical study, set out in the case "Complex of military means and its use" (sections 2 and 3). Behind the typological and chronological rows, I wanted to imagine the ancient warriors and gunsmiths, find out how and what they were equipped with, how they used their weapons when they rode a horse or acted as infantrymen.
