 The quartered military forces were being formed from among married soldiers, who had already served in the army for no less than six years, and local men (mainly, peasants) between 18 and 45 years of age.Both of these categories were called "master settlers" (поселяне-хозяева).The rest of the locals of the same age, who had been fit for military service, but had not been chosen, were being enlisted as assistants to their masters and were a part of reserve military subdivisions.
