|First mention||"The Gamekeeper"|
In 1982, Boris was taken hostage in an mansion located in East Germany. He was kept here during the day, and taken underground during the night. According to satellite recon, he was supposed to have only two guards inside with no snipers. A commando team, led by Colonel John Michaels, including Captains Jack O'Neill and Charles Kawalsky, was sent to grab him. This mission turned badly and Michaels was deadly shot by a sniper (SG1: "The Gamekeeper").
- This character is mentionned only. We don't see him, even in the Keeper's hallucination.
- Boris' fate is unknown.
