Foma Zhilin was a military officer who worked on Russian Stargate Program. Six days before the Russian Stargate Program was shut down, he left Earth via the Stargate as part of Major Valentine Kirensky's team. Ultimately he and his group were trapped in a ziggurat and killed by a Carnivorous creature. (SG1: "The Tomb")
