Miraslov Kiselev

General Kiselev was the Minister of Defense of Russia in the year 2005. He was implanted a Goa'uld symbiote by the Trust and tried to provoke a nuclear war between Russia and the United States. However, Samantha Carter was able to expose him by discovering that he stopped wearing his glasses despite his previously poor eyesight, as the symbiote cured it. He was then stopped by President Mikhailov before he could launch an attack on the United States.

Behind the scenes
In reality, his office was held at that time by Sergei Ivanov, who is a civilian and most definitely has never been a Goa'uld host.
