MI11, or Military Intelligence, Section 11, was a department of the British Directorate of Military Intelligence, part of the War Office.
During the Second World War, MI11 was responsible for field security: protecting British military personnel from enemy agents and "fifth columnists" amongst civilian populations, in theatres of war. As such, MI11 assumed a role formerly assigned to the Field Security Police (which had itself replaced the British Army's Intelligence unit before World War I).
Section 11 was disbanded after World War II.

The Security Service, also known as MI5, is the United Kingdom's domestic counter-intelligence and security agency and is part of its intelligence machinery alongside the Secret Intelligence Service (MI6), Government Communications Headquarters (GCHQ), and Defence Intelligence (DI). MI5 is directed by the Joint Intelligence Committee (JIC), and the service is bound by the Security Service Act 1989. The service is directed to protect British parliamentary democracy and economic interests and to counter terrorism and espionage within the United Kingdom (UK).
Counterintelligence (counter-intelligence) or counterespionage (counter-espionage) is any activity aimed at protecting an agency's intelligence program from an opposition's intelligence service. It includes gathering information and conducting activities to prevent espionage, sabotage, assassinations or other intelligence activities conducted by, for, or on behalf of foreign powers, organizations or persons.
Intelligence assessment, or simply intel, is the development of behavior forecasts or recommended courses of action to the leadership of an organisation, based on wide ranges of available overt and covert information (intelligence). Assessments develop in response to leadership declaration requirements to inform decision-making. Assessment may be executed on behalf of a state, military or commercial organisation with ranges of information sources available to each.
The Intelligence Corps is a corps of the British Army. It is responsible for gathering, analysing and disseminating military intelligence and also for counter-intelligence and security. The Director of the Intelligence Corps is a brigadier.
A military staff or general staff is a group of officers, enlisted and civilian staff who serve the commander of a division or other large military unit in their command and control role through planning, analysis, and information gathering, as well as by relaying, coordinating, and supervising the execution of their plans and orders, especially in case of multiple simultaneous and rapidly changing complex operations. They are organised into functional groups such as administration, logistics, operations, intelligence, training, etc. They provide multi-directional flow of information between a commanding officer, subordinate military units and other stakeholders. A centralised general staff results in tighter top-down control but requires larger staff at headquarters (HQ) and reduces accuracy of orientation of field operations, whereas a decentralised general staff results in enhanced situational focus, personal initiative, speed of localised action, OODA loop, and improved accuracy of orientation.

A radio listening station is a facility used for military reconnaissance, especially telecommunications reconnaissance by "intercepting" radio transmitter communications. In contrast to the original eavesdropping on an acoustic speech conversation, radio eavesdropping stations are used to eavesdrop on the information transmitted wirelessly using radio technology. For this purpose, highly sensitive radio receivers and suitable receiving antennas are used.

The Canadian Intelligence Corps is an administrative corps of the Canadian Army (CA); it includes all CA members of the Canadian Armed Forces' Intelligence Branch. Prior to the Unification of the Canadian Armed Forces in 1968, it enjoyed the same status as an administrative corps of the Canadian Army. The C Int C was never disbanded; however, it was effectively reduced to nil strength at Unification, and entered an administrative hibernation with its personnel and duties assigned to the new Security Branch. The Intelligence Branch was separated from the Security Branch in 1981. In December 2016 the C Int C title was restored by the Chief of the Defence Staff (Canada) within the construct of the Intelligence Branch.

With the rise of easily-intercepted wireless telegraphy, codes and ciphers were used extensively in World War I. The decoding by British Naval intelligence of the Zimmermann telegram helped bring the United States into the war.
National governments deal in both intelligence and military special operations functions that either should be completely secret, or simply cannot be linked to the sponsor. It is a continuing and unsolved question for governments whether clandestine intelligence collection and covert action should be under the same agency. The arguments for doing so include having centralized functions for monitoring covert action and clandestine HUMINT and making sure they do not conflict, as well as avoiding duplication in common services such as cover identity support, counterespionage, and secret communications. The arguments against doing so suggest that the management of the two activities takes a quite different mindset and skills, in part because clandestine collection almost always is on a slower timeline than covert action.

The Government of the United Kingdom maintains several intelligence agencies that deal with secret intelligence. These agencies are responsible for collecting, analysing and exploiting foreign and domestic intelligence, providing military intelligence, and performing espionage and counter-espionage. Their intelligence assessments contribute to the conduct of the foreign relations of the United Kingdom, maintaining the national security of the United Kingdom, military planning, public safety, and law enforcement in the United Kingdom. The four main agencies are the Secret Intelligence Service, the Security Service (MI5), the Government Communications Headquarters (GCHQ) and Defence Intelligence (DI). The agencies are organised under three government departments, the Foreign Office, the Home Office and the Ministry of Defence.
