Intelligence Corps

3 Military Intelligence

3 Military Intelligence Battalion

3 Military Intelligence Battalion is an Army Reserve unit under the operational command of 1 Intelligence Surveillance and Reconnaissance Brigade and is based in London and Cambridge.

Our Battalions

The Battalion has four Military Intelligence (MI) companies (Coy).

  • 31 MI Coy is co-located with the Battalion Headquarters in Ashford House Army Reserve Centre on Worship Street, very close to the City
  • 32 MI Coy is located at Coldham’s Lane Army Reserve Centre in Cambridge
  • 33 and 34 MI Coys are located in Hampstead, in Edinburgh House on Fitzjohn’s Avenue

Our deployments

The Battalion is extremely operationally focussed, with a very large number of its officers and soldiers having completed operational deployments. In the past, the Unit has deployed personnel to Kuwait, the Balkans, Sierra Leone, Iraq, most recently to Afghanistan and in support of operations in Libya.

They also support deployed personnel working within the London area. When deployed they are completely integrated with and work alongside their Regular Army Intelligence Corps counterparts.

Our people

Like every other Intelligence Corps Unit, the Battalion's strength is its people. Their common motive for joining is to seek an intellectual and physical challenge and work within the intelligence arena. They come from a range of backgrounds and represent a cross section of high calibre talent from across London, the Home Counties and the South East Region of the UK.

Our people come from all walks of life including professional and non-professionals. There are entry criteria and all applicants wishing to join are put through a Technical Selection process, to ensure they have the right aptitudes and motivations for intelligence work, plus ensuring that this is something that they wish to get involved with.



On joining the Battalion all personnel undergo initial Phase 1 training to become a soldier. Afterwards there's a varied and challenging Phase 2 Intelligence training package. 

The Battalion delivers competent MI Operators who are highly capable analysts and confident leaders and soldiers. As analysts the training emphasis is on building strong, core Operational Intelligence (OPINT) skills, overlaid by an understanding of actual and emerging threats and theatres of operation.

Analysts need to be able to draw information from a wide range of sources, classified or open. They must be able to understand complex situations and then communicate their conclusions to decision makers often under the pressures of time and the operational situation.
