1814–1914Edit

In the 19th century, British intelligence work was undertaken by the Intelligence Department of the War Office. An important figure was Sir Charles Wilson, a Royal Engineer who successfully pushed for reform of the War Office's treatment of topographical work.^[1]

In the early 1900s intelligence gathering was becoming better understood, to the point where a counter-intelligence organisation (MI5) was formed by the Directorate of Military Intelligence (DoMI) under Captain (later Major-General) Vernon Kell; overseas intelligence gathering began in 1912 by MI6 under Commander (later Captain) Mansfield Smith-Cumming.^[2]

1914–1929Edit

Although the first proposals to create an intelligence corps came in 1905, the first Intelligence Corps was formed in August 1914 and originally included only officers and their servants. It left for France on 12 August 1914.^[3] The Royal Flying Corps was formed to monitor the ground, and provided aerial photographs for the Corps to analyse.^[4]

During the Irish War of Independence, Intelligence Corps operatives were used to monitor the Irish Republican Army. Following the war the Intelligence Corps was gradually scaled down and disbanded entirely in 1929; intelligence matters were left to individual unit officers.^[5][6][7]

Second World WarEdit

On 19 July 1940 a new Intelligence Corps was created by Army Order 112 and has existed since that time. The Army had been unprepared for collecting intelligence for deployment to France, and the only intelligence had been collected by Major Sir Gerald Templer. The Corps trained operatives to parachute at RAF Ringway; some of these were then dropped over France as part of the Special Operations Executive (SOE). Intelligence Corps officers were involved in forming the highly-effective Long Range Desert Group, and Corps officer Lt Col Peter Clayton was one of the four founders of the Special Air Service (SAS). Around 40 per cent of British Army personnel at Bletchley Park were in the Intelligence Corps.^[8]

The Combined Allied Intelligence Corps as it was known in Malta, began recruiting in 1940 following Italy’s entry into the war on the side of Germany.^[9] Among its many responsibilities in the Mediterranean Theatre were debriefing and interrogation of high-ranking prisoners of war in East Africa following Mussolini's invasion of Abyssinia (“Eldoret” P.O.W. Camp no. 365 being one example), counter-intelligence operations following Operation Husky the Allied invasion of Sicily in August 1943, and implementation of the Allied Screening Commission.^[9] The Commission was established by Field-Marshal Sir Harold Alexander a few days after the fall of Rome in June 1944 to identify and reimburse Italian civilians who had assisted Allied escapees.^[10]

Cold WarEdit

Throughout the Cold War, Intelligence Corps officers and NCOs (with changed insignia) were posted behind the Iron Curtain in East Germany, to join in the intelligence-gathering activities of the British Commanders'-in-Chief Mission to the Soviet Forces in Germany (Brixmis).^[11]

Northern IrelandEdit

Many members of the Intelligence Corps served in Northern Ireland during "the Troubles". Units such as the Military Reaction Force, Special Reconnaissance Unit, Force Research Unit and 14 Intelligence Company contained Corps soldiers and officers.^[12]

DesignationEdit

On 1 February 1985 the corps was officially declared an 'Arm' (combat support) instead of a 'Service' (rear support).^[8]

Intelligence Corps personnel wear a distinctive cypress green beret with a cap badge consisting of a union rose (a red rose with a white centre) between two laurel branches and surmounted by a crown. (According to the late Gavin Lyall, the Intelligence Corps cap badge is referred to jokingly as "a rampant pansy resting on its laurels".) Their motto is Manui Dat Cognitio Vires ("Knowledge gives Strength to the Arm"). The corps' quick march is The Rose & Laurel while its slow march is Henry Purcell's Trumpet Tune & Ayre.^[13] Due to the colour of the beret, Intelligence Corps personnel are often referred to as 'Green Slime', or simply 'Slime' by fellow soldiers.^[14]

Their headquarters, formerly at Maresfield, East Sussex, then Templer Barracks at Ashford, Kent, moved in 1997 to the former Royal Air Force station at Chicksands in Bedfordshire along with the Defence Intelligence and Security Centre (DISC).^[13] DISC was renamed as Joint Intelligence Training Group in January 2015.^[15]

The Intelligence Corps Museum was created in 1969,^[16] and later renamed as the Military Intelligence Museum, now also at Chicksands. As a working military base, the Museum can be visited by appointment only.^[17]

The corps has a particularly high proportion of commissioned officers, many of them commissioned from the ranks, and also a high percentage of female members. Non-commissioned personnel join as an Operator Military Intelligence (OPMI) or Operator Military Intelligence (Linguist) (OPMI(L)). They do basic 14-week military training at either the Army Training Centre Pirbright, or the Army Training Regiment, Winchester.^[18] OPMI soldiers then will complete a 20-week special-to-arm training at Templer Training Delivery Wing, Chicksands, at the end of which they are promoted to Lance Corporal and posted to a battalion.^[19]
