Officer corps of Siberian garrison battalions in early 1770s (from the service records’ data)

The article represents results of studies made upon the officer corps’ personnel in garrison battalions, serving at Siberia in the 2 nd half of 18 th century. Using the archive sources, studied for a first time, the author has determined some quality parameters of officers contingent: their social origin, military experience, disciplinary metrics. It has been established that descendants from non-privileged groups, coming from Russia’s european part, prevailed among Siberian garrison forces’ officers. This fact shows a considerable scale of transferring officers from European Russia’s provinces to serve in the complement of Siberian corps. There were quite a lot of people, who had taken part in some military campaigns, with a serious military experience.
