Nikolai Stepanovich Sokolov

Nikolai Stepanovich Sokolov is a Russian scientist who defected to the US shortly after the beginning of the Cold War. He was the head of the OKB-754 before he defected.

October 16, 1962. President Kennedy received word that the Soviets were in the process of deploying intermediate-range ballistic missiles in Cuba. The president demanded that the Soviets dismantle and remove the missiles. At the same time, he announced a naval blockade to prevent further missile shipments from reaching Cuba. But the Soviets didn't back down, instead placing their armed forces on secondary alert. Soviet transport ships carrying missiles continued on course toward Cuba. US and Soviet forces went on alert for an all-out nuclear war. Frantic negotiations were conducted through the UN's Emergency Security Council and unofficial channels to end the hair-trigger standoff. Finally, on October 28, the Soviet Union agreed to remove its missiles from Cuba. And so the world avoided a nuclear holocaust. But in exchange the Americans had to surrender Sokolov over to the Russians. He was then placed in an abandoned research facility near the OKB-812, and was gaurded by soldiers in order to prevent Colonel Volgin from kidnapping Sokolov to make him work on the Shagohod.

After Naked Snake succeeds in rescuing Sokolov he is quickly confronted by The Boss who tells Snake of her defection, she then takes Sokolov as a "gift" for Volgin. They also take Tatyana (a.k.a. EVA) who is Volgin's lover. After Volgin feels Sokolov has served his purpose, he tortures and eventually kills him.
