Boys aged 15 or 16 had to undergo basic military training in their final year at school. Some orphans and other children deprived of parental care were “adopted” by military units, lived in military barracks and received military training in school. Boys and girls studying at Military Educational Institutes from the age of 16 were regarded as being on military service. Under-18s were reportedly recruited into opposition separatist forces in the Chechen Republic and other parts of the north Caucasus.
