Operation Anadyr
Operation Anadyr () was the code name used by the Soviet Union for its Cold War secret operation in 1962 of deploying ballistic missiles, medium-range bombers, and a division of mechanized infantry to Cuba to create an army group that would be able to prevent an invasion of the island by United States forces. The plan was to deploy approximately 60,000 personnel in support of the main missile force, which consisted of three R-12 missile regiments and two R-14 missile regiments. However, part of it was foiled when the United States discovered the plan, prompting the Cuban Missile Crisis.
