Operation Temperer

Operation Temperer is a British government plan to deploy troops to support and free up police officers in key locations following a major terrorist attack or major public disorder. It was put into effect for the first time on 22 May 2017 following the bombing of an Ariana Grande concert at Manchester Arena[1] and for a second time following the Parsons Green bombing.

HQ Standing Joint Commander (UK) is militarily responsible for directing the deployment, if ordered.[2]

Background

The plan provides for up to 5,100 service personnel from all 3 services to be deployed to "augment armed police officers engaged in protective security duties" at key sites in the United Kingdom.[1] In practice, troops and military police would replace some police officers particularly from the Metropolitan Police, Ministry of Defence Police and the Civil Nuclear Constabulary guarding sites of national interest or critical national infrastructure such as Nuclear power stations, military garrisons, Buckingham Palace and Parliament so they can be deployed on either armed or unarmed frontline operational duties.

According to government sources cited by the Daily Telegraph, it would only be triggered following a COBR meeting. The plan was put in place following the January 2015 Île-de-France attacks in France. It was intended to be kept secret, but was accidentally disclosed in July 2015 after being inadvertently uploaded to the website of the National Police Chiefs' Council.[3] It was said to have been contentious with the Army leadership, due to concerns about it causing overstretch, training given to troops, morale problems and difficulties with deciding when to end the operation.[4]

The British armed forces have previously deployed to support the police, most notably during the Troubles in Northern Ireland when 21,000 troops were deployed to assist the Royal Ulster Constabulary in Operation Banner. In 2003, Tony Blair's government temporarily deployed 450 troops to Heathrow Airport and other London locations during a period of heightened terrorist threat.[4] Plans to support the police and increase the numbers of officers deployed on the streets began after the 2011 England riots

Other European countries have also deployed troops to guard against terrorist threats in cities; France has deployed over 10,000 troops under Operation Sentinelle since the January 2015 attacks in the Paris region,[4] and Italy also deployed 4,800 troops in Rome and other cities in February 2015.[5]
