The Winter Soldier Program was a top secret HYDRA project started by Arnim Zola in the 1940s to brainwash American soldier James Buchanan Barnes, whom he had administered with his own version of the Super Soldier Serum, and turn him into a super soldier assassin known as the Winter Soldier. Following World War II, the Soviet Union was heavily involved with the program as well.
