Activities
The Brigade participated in a two-week disaster relief exercise in Bosnia and Herzegovina. It deployed to the Philippines in April 2015 to assist the Philippines Government in developing their contingency plans for natural disasters. 77th Brigade has formed a formal partnership with the 361st Civil Affairs Brigade, US Army Europe. The Brigade uses social media such as Twitter and Facebook as well as psyop techniques to influence populations and behaviour. David Miller said that it is "involved in manipulation of the media including using fake online profiles". In late September 2019 the Middle East Eye reported that Gordon MacMillan, a Twitter executive with editorial control over the Middle East and North Africa, is also a reservist officer in the 77th Brigade. Both Twitter and the British Army denied that they have a relationship or agreement. David Miller, a professor of political sociology at the University of Bristol who studies British government propaganda and public relations, said it was hypocritical of Twitter to close accounts alleged to be connected with non-Western governments while having links to the British Army. During the UK government's daily coronavirus briefing, 22 April 2020, Nick Carter confirmed that 77th Brigade are working with the Home Office Rapid Response Unit "helping to quash rumours from misinformation, but also to counter disinformation”. On 7 May 2020, The Economist interviewed General Sir Nick Carter on the role of 77 Brigade in fighting coronavirus disinformation.
