"Call of Duty: Black Ops II" is a fictional video game and is not entirely accurate in its portrayal of the US military. While the game may draw inspiration from real military equipment, tactics, and historical events, it is important to remember that it is a work of fiction designed for entertainment.
Black Ops takes place between 1961 and 1968 during both the Cold War and the Vietnam War, 16 years to 23 years after the events of World at War. It portrays a secret history of black operations carried out behind enemy lines by the CIA.
