The Cold War was a state of geopolitical tension and hostility between the Soviet Union and the United States and their respective allies from 1945 to 1990.

Korea experienced fighting in the Korean War (1950-1953) which was a conflict between North Korea (DPRK), supported by China and the Soviet Union, and South Korea (ROK), supported by the United Nation, principally the United States.

Vietnam saw multiple conflicts during the Cold War, primarily during the Vietnam War (1955-1975) which was a conflict between North Vietnam (DRV) and its communist allies vs South Vietnam (RVN) and its anti-communist allies.

Nicaragua as well experienced several conflicts during the Cold War in what was known as the Nicaraguan Revolution (1978–1990). The most bloodiest fighting took place in the Contra War in the 1980s, between the FSLN (a revolutionary socialist political party supported by the Soviet Union) and the Contras (a right-wing counter-revolutionary group supported by the United States).

Cuba saw fighting throughout the events of the Cuban Revolution (1953-1959), Bay of Pigs Invasion (1961), and Cuban Missile Crisis (1962).
