An authorised firearms officer (AFO) is a British police officer who is authorised and trained to carry and use firearms. The designation is significant because most police officers in the United Kingdom do not routinely carry firearms. The only forces where officers are routinely armed are the Police Service of Northern Ireland, the Ministry of Defence Police, the Civil Nuclear Constabulary, Belfast Harbour Police and the Belfast International Airport Constabulary.
In 2019/20 fiscal year, there were 19,372 police operations throughout England and Wales in which the deployment of firearms was authorised and 6,518 firearms officers, 4.9% of the 132,467 active full-time equivalent officers.[1] Following the November 2015 Paris attacks, the decision was made to significantly increase the numbers of armed officers, particularly in London.[2]
AFOs can be up-skilled with additional qualifications, such as Armed Response Vehicle Officer (ARVO), Specialist Firearms Officer (SFO), and Counter Terrorist Specialist Firearms Officer (CTSFO), alongside other specialities, including rifles.
