The Cherbourg Project was an Israeli military operation that took place on 24 December 1969 and involved the escape of five remaining armed Sa'ar 3 class boats from the French port of Cherbourg. The boats had been paid for by the Israeli government but had not been delivered due to the French arms embargo in 1969. The whole operation was planned by the Israeli Navy, and was codenamed Operation Noa, after the daughter of Captain Binyamin "Bini" Telem.

Operation Banner was the operational name for the British Armed Forces' operation in Northern Ireland from 1969 to 2007, as part of the Troubles. It was the longest continuous deployment in British military history. The British Army was initially deployed, at the request of the unionist government of Northern Ireland, in response to the August 1969 riots. Its role was to support the Royal Ulster Constabulary (RUC) and to assert the authority of the British government in Northern Ireland. This involved counter-insurgency and supporting the police in carrying out internal security duties such as guarding key points, mounting checkpoints and patrols, carrying out raids and searches, riot control and bomb disposal. More than 300,000 soldiers served in Operation Banner. At the peak of the operation in the 1970s, about 21,000 British troops were deployed, most of them from Great Britain. As part of the operation, a new locally-recruited regiment was also formed: the Ulster Defence Regiment (UDR).

Operation Giant Lance was an undercover military operation by the United States in which the primary objective was to apply military pressure towards the Soviet Union during the Cold War.. Initiated on October 27th, 1969, President Richard Nixon authorized a squadron of 18 B-52 bombers to patrol the glacier caps around Moscow and escalate the nuclear threat poised. The goal was to coerce both the Soviet Union and North Vietnam to agree on favourable terms with the US, and conclusively end the Vietnam war. The operation’s effectiveness was also largely built on Nixon’s consistent madman theory diplomacy, in order to influence Moscow’s decision even more. The operation was kept top secret from both the general public and higher authorities within the Strategic Air Command, intended to only be noticed by Russian intelligence. The operation lasted one month before being called off.

The United States's Mandrel nuclear test series was a group of 52 nuclear tests conducted in 1969–1970. These tests followed the Operation Bowline series and preceded the Operation Emery series.
