Which country's longest continuous deployment began because of intense political and sectarian rioting in Northern Ireland?
Operation Banner Operation Banner was the operational name for the British Armed Forces' operation in Northern Ireland from August 1969 to July 2007, as part of the Troubles. It was the longest continuous deployment in the British military's 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. At the peak of the operation in the 1970s, about 21,000 British troops were deployed, most of them from Britain. As part of the operation, a new locally-recruited regiment was also formed: the Ulster Defence Regiment (UDR).
Combat Aviation Brigade, 101st Airborne Division The Combat Aviation Brigade, 101st Airborne Division is a combat aviation brigade of the United States Army. It was first organized in July 1968 as an aviation group and stands as the most decorated aviation unit in the United States Army. It was redesignated an aviation brigade in 1986. It has served in almost every single military operation (combat, peacekeeping, and humanitarian) since the Vietnam War. In support of the Global War on Terror, the CAB has distinguished itself as the military's premiere combat aviation unit during its two deployments to Iraq (2003 and 2005) and five deployments to Afghanistan (2002, 2007, 2010, 2012, and 2015). The brigade has flown hundreds of thousands of hours during these combat tours, transporting millions of troops around the battlefield and providing close air support/aerial reconnaissance. The 101st broke its own record for longest air assault in history during the invasion of Iraq in 2003. Previously, the longest air assault was conducted in 1991 during Operation Desert Storm.
