The Metropolitan Police Service (MPS), formerly and still commonly referred to as the Metropolitan Police, is the territorial police force responsible for law enforcement and the prevention of crime within the ceremonial county of Greater London.

The City of London Police is the territorial police force responsible for law enforcement within the City of London, England, including the Middle and Inner Temples. The force responsible for law enforcement within the remainder of the London region, outside the city, is the much larger Metropolitan Police, a separate organisation.

The Association of Chief Police Officers of England, Wales and Northern Ireland (ACPO) was a not-for-profit private limited company that for many years led the development of policing practices in England, Wales, and Northern Ireland. Established in 1948, ACPO provided a forum for chief police officers to share ideas and coordinate their strategic operational responses, and advised government in matters such as terrorist attacks and civil emergencies. ACPO coordinated national police operations, major investigations, cross-border policing, and joint law enforcement. ACPO designated Senior Investigative Officers for major investigations and appointed officers to head ACPO units specialising in various areas of policing and crime reduction.

A firearms unit is an armed unit within each territorial police force in the United Kingdom. For the most part, the police forces of the United Kingdom are unarmed; however, all have firearms units to provide the police force with the capability to deal with terrorists and armed criminals. A police officer cannot apply to join the firearms unit without first finishing their two-year probationary period, with a further two years in a core policing role for some forces. Firearms unit is the most common name outside of the capital, while that of London's Metropolitan Police Service is called the Specialist Firearms Command, Trojan or SC&O19. Within the media it is sometimes compared to the SWAT units of the United States.
In the United Kingdom police firearm policy varies by constituent countries. In Northern Ireland, all police officers carry firearms whereas in the rest of the United Kingdom, firearms are carried only by specially-trained firearms officers. The arming of police in Great Britain is a much debated topic.
A specialist firearms officer (SFO) is a British police officer who has undergone training in the use of police firearms to a more advanced level than authorised firearms officers (AFOs). SFOs receive additional training in areas such as building assault and specialist weapon usage.

The National Crime Agency (NCA) is a national law enforcement agency in the United Kingdom. It is the UK's lead agency against organised crime; human, weapon and drug trafficking; cybercrime; and economic crime that goes across regional and international borders; but it can be tasked to investigate any crime. The NCA has a strategic role as part of which it looks at serious crime in aggregate across the UK, especially analysing how organised criminals are operating and how they can be disrupted. To do this, it works closely with regional organised crime units (ROCUs), local police forces, and other government departments and agencies.

The firearms units of police forces organise CTSFOs into teams to establish a police tactical unit.
