Captain Zhukov was at the helm of a Soviet nuclear submarine named Firebird in 1983 when the Doctor and Clara arrived via the TARDIS (thinking they were in Las Vegas.) And a good thing they were there, because the sub had taken in a block of ice that held a cryogenically preserved "Ice Warrior" - one of the reptilian soldiers that once held sway over the planet Mars, at least until 5000 years ago.
SGT. SERGEI ZHUKOV
Zhukov had a sister who lived in the Siberian region of the USSR. When an American pilot named Harmon Rabb was brought to Russia after being shot down over North Vietnam in 1969, he escaped and was given shelter by Zhukov's sister. They eventually gave in to their natural desires for each other and she gave birth to his second son, Sergei Zhukov, who would become a sergeant in the Russian army. (Harmon Rabb's older son and Sergie's half brother was Harmon Rabb, Jr., a Junior Advocate General in the US Navy.) The sister would eventually die while saving her lover's life.
