Oleksiy is a character that appears in the film, Without Remorse.
In 2019, Oleksiy and several other mercenaries were hired by CIA agent Robert Ritter to locate Viktor Rykov. They managed to track down Rykov to an apartment complex in Murmansk, Russia. Oleksiy and the other mercenaries then set up surveillance equipment in an adjacent apartment to monitor Rykov. Once Ritter and his team arrived at the apartment, Oleksiy told him that Rykov had two body guards. The plan was Oleksiy to help smuggle Rykov out of the country to a U.S. base in Finland. This never happened, however, as Rykov killed himself with a suicide vest and Ritter's team was ambushed. Oleksiy and the other mercenaries presumably fled the scene.
