Voyi
Voyi (singular voi or voy) was a category of armed forces in ancient Rus.
Unlike the standing force druzhina, voi force was drafted from a local population. Next to the druzhina, the voyi formed a basis of an army in Rus'. A Voivode (voi - "army", vode - "to lead", meaning " Warlord") was appointed by a prince ( knyaz) in charge of them.
