The Virtuous Mission was a CIA operation in August of 1964 that involved a deep insertion inside the Soviet Union. A FOX agent codenamed Naked Snake was deployed via the world's first HALO jump in order to rescue a Soviet defector, the weapons scientist Nikolai Stepanovich Sokolov. While Snake succeeded in locating and extracting Sokolov from his KGB guards, he was subsequently attacked and critically injured by a defecting American agent. Sokolov was then re-captured, and the GRU officer Volgin not only seized Sokolov's project, but also unleashed an American-made Davy Crockett nuclear weapon on Russian citizens, creating an international incident.
