The Special Reconnaissance Unit, also known as the 14 Field Security and Intelligence Company (internally "The Det") was a part of the British Army Intelligence Corps involved in plainclothes operations in Northern Ireland from the 1970s onwards.

The unit conducted undercover surveillance operations against suspected members of Irish republican and loyalist paramilitary groups. Its troops were recruited from line battalions and trained in an eight-week course by the Special Air Service (SAS). An initial deployment of 120 men took place in November 1972. They are commandos trained for clandestine operation, counterinsurgency, covert operation, intelligence gathering, military intelligence, special reconnaissance, surveillance, tracking down and arresting or killing members IRA missions. Allegations of collusion with loyalist paramilitaries were made against the unit. In 1987, the unit became part of the newly formed United Kingdom Special Forces directorate. The unit formed the Special Reconnaissance Regiment in 2005.

Predecessor

The Special Reconnaissance Unit, also known as 14 Intelligence Company, was the successor to the Military Reaction Force (MRF). Selection to 14 Intelligence Company was available to all serving members of the British armed forces and to both sexes. For the first time, women could become members of a UK Special Forces unit. Candidates were required to pass a rigorous selection process, designed to select the individuals who possessed the necessary qualities to deal with undercover covert operations they'd be tasked with. In one selection course, out of 1000 applicants who applied, only 17 were deployed to Northern Ireland.

Wilson briefing

"Special Reconnaissance Unit" is the term appearing in official documents from the 1970s. An April 1974 briefing for Prime Minister Harold Wilson states: The term "Special Reconnaissance Unit" and the details of its organisation and mode of operations have been kept secret. The SRU operates in Northern Ireland at present under the cover name "Northern Ireland Training and Advisory Teams (Northern Ireland)" – NITAT(NI) – ostensibly the equivalent of genuine NITAT teams in UKLF and BAOR.

Selection and training of personnel from all arms of the British Armed Forces was conducted in a number of locations in Great Britain. Candidates, both male and female, volunteered for special duties for periods of 18–36 months, before being returned to a parent unit. Trained surveillance operators could volunteer for re-deployment after a period with the parent unit, with potential opportunities to serve in command, staff or training roles within the organisation or higher command structure.
