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).

The Falls Curfew, also called the Battle of the Falls, was a British Army operation during 3–5 July 1970 in the Falls district of Belfast, Northern Ireland. The operation began as a search for weapons in the staunchly Irish nationalist district. As the search ended, local youths attacked the British soldiers with stones and petrol bombs and the soldiers responded with CS gas. This quickly developed into gun battles between British soldiers and the Irish Republican Army (IRA). After four hours of continuous clashes, the British commander sealed off the area, which comprised 3,000 homes, and imposed a curfew which would last for 36 hours. Thousands of British troops moved into the curfew zone and carried out house-to-house searches for weapons, while coming under intermittent attack from the IRA and rioters. The searches caused much destruction, and a large amount of CS gas was fired into the area. Many residents complained of suffering abuse at the hands of the soldiers. On 5 July, the curfew was brought to an end when thousands of women and children from Andersonstown marched into the curfew zone with food and other supplies for the locals.
