Historical Evolution
Early Foundations (Pre-1914)
The genesis of organized military intelligence within the British Army can be traced back to the 19th century with the Intelligence Department of the War Office. Figures like Sir Charles Wilson championed the integration of topographical work, laying groundwork for more systematic intelligence gathering. By the early 20th century, nascent counter-intelligence (MI5) and overseas intelligence (MI6) organizations were established, signaling a growing recognition of intelligence's strategic importance.
World War I and Disbandment (1914-1929)
The first iteration of the Intelligence Corps was formed in August 1914, initially comprising officers and their servants. It played a role in World War I, analyzing aerial photographs provided by the Royal Flying Corps. During the Irish War of Independence, operatives were deployed to monitor the Irish Republican Army, tragically resulting in the loss of several intelligence officers on Bloody Sunday in 1920. Post-war, the Corps was gradually reduced and ultimately disbanded in 1929, with intelligence duties reverting to individual unit officers.
Re-establishment and World War II (1940-1945)
Recognizing the critical need for organized intelligence capabilities, the Intelligence Corps was re-established on July 19, 1940. It trained operatives for specialized roles, including airborne deployment for the Special Operations Executive (SOE) and participation in formations like the Long Range Desert Group. Notably, Intelligence Corps personnel constituted approximately 40% of the staff at Bletchley Park, the hub of British codebreaking efforts. The Corps also played a significant role in the Mediterranean Theatre, conducting counter-intelligence and managing Allied screening commissions.
Cold War and Northern Ireland Operations
During the Cold War, Intelligence Corps personnel were instrumental in intelligence-gathering operations behind the Iron Curtain, notably with the British Commanders'-in-Chief Mission to the Soviet Forces in Germany (BRIXMIS). The Corps also maintained a significant presence in Northern Ireland throughout "The Troubles," contributing to units like the Military Reaction Force and Force Research Unit, tasked with gathering intelligence on paramilitary organizations.
Corps Traditions & Identity
The Cypress Green Beret
Personnel of the Intelligence Corps are distinguished by their distinctive cypress green beret. This unique color sets them apart within the British Army. The cap badge features a union rose, symbolizing the United Kingdom, nestled between two laurel branches, representing achievement and distinction, all surmounted by a crown, signifying allegiance to the monarchy.
Motto and Marches
The Corps' motto, Manui Dat Cognitio Vires, translates to "Knowledge gives Strength to the Arm," encapsulating the core mission of intelligence work. The Corps' quick march is the spirited "Rose & Laurel," while its slow march is Henry Purcell's stately "Trumpet Tune & Ayre," reflecting both operational tempo and ceremonial tradition.
Nicknames and Culture
Due to the distinctive color of their beret, members of the Intelligence Corps are often colloquially referred to as "Green Slime" or simply "Slime." While sometimes perceived as informal, these nicknames are part of the Corps' unique cultural identity and shared experience among its members.
Key Locations
Historical Bases
Throughout its history, the Intelligence Corps has been headquartered in various significant locations. During World War II, its depot was situated at Wentworth Woodhouse in South Yorkshire. Post-war, it moved to Maresfield Camp in East Sussex in 1948, before relocating to Templer Barracks in Ashford, Kent, in 1966. These locations served as crucial centers for training and administration.
Modern Headquarters
In 1997, the Corps relocated its headquarters to MOD Chicksands in Bedfordshire, consolidating operations with the Defence Intelligence and Security Centre (DISC). DISC was subsequently renamed the Joint Intelligence Training Group (JITG) in January 2015. The Intelligence Corps Museum, established in 1969 and later renamed the Military Intelligence Museum, is also located at Chicksands, offering a repository of the Corps' history.
Training and Advancement
Entry-Level Training
The Intelligence Corps attracts a diverse range of personnel, with a notable proportion of commissioned officers, many promoted from the ranks, and a significant percentage of female members. New recruits typically undergo basic military training at the Army Training Centre Pirbright or the Army Training Regiment, Winchester, completing a 14-week program. This foundational training ensures all personnel meet the rigorous standards of the British Army.
Specialization and Promotion
Following basic training, Operator Military Intelligence (OPMI) and Operator Military Technical Intelligence (OPTI) soldiers proceed to specialized, 20-week training at the Templer Training Delivery Wing at Chicksands. Upon completion, they are promoted to Lance Corporal and posted to operational battalions. This structured progression ensures a continuous pipeline of skilled intelligence professionals ready to support various military operations.
Current Operational Units
Structure and Command
The Intelligence Corps operates under the command of the Intelligence, Surveillance and Reconnaissance (ISR) Group within Field Army Troops. Its structure includes Corps Headquarters at MOD Chicksands, various specialist groups, and multiple Military Intelligence (MI) Battalions, both regular and reserve, strategically located across the United Kingdom and supporting specific divisions and brigades.
