Oleg was born in Lopatino, his parents were members of the WMDA, and were disliked in the City of Lopatino because of their political beliefs. His father wasn't the nicest person, he believe in hard justice, if you made a mistake, he'd beat you. When he was drunk he would beat you and his wife. He only allowed Pro-Russian, and Pro-WMDA items, movies, tv shows, newspapers in the house, anything Anti-WDMA was immediately removed. On a cold winters night, while the family was asleep, Anti-WMDA thugs intruded into the Kazimir household and took his father, and mother into the street. They were strung up, hanged, and quartered, and their heads put on a spike outside their house. They were marked with "WMDA Scum", they forced little Oleg to watch, and they swiftly left once National Police were on their way.
Upon hearing this, members of (Formerly) WMDA quickly rescued Oleg, and brought him to Sinistok, and moved him into the camp in the forest. He was now placed into the camp with other children his age, and began psychological training, and taught him Pro-Russian beliefs, and Pro-Communist beliefs. Once he turned 14, he was then moved to a camp up north to a Chedaki camp to began his Paramilitary training. In 2009, Oleg was a fully fledged member of the ChDKZ and he was involved in attacks against Government Forces, Nationalists, and USMC. He was especially brutal against Nationalist Forces, after they slaughtered his parents like cattle. This did not help his mental state and started attacking Chernarussian Citizens who were Pro-Nationalist. As Chedaki was losing ground, his platoon moved up north and hid in the forests. The leader sent out a scouting party into Tisy and identified local Nationalists operating in the area, his platoon massed enough forces to now make a move in the North of Chernarus.
