1st Intelligence, Surveillance and Reconnaissance Brigade

1st Intelligence, Surveillance and Reconnaissance Brigade deploys Intelligence, Surveillance and Reconnaissance (ISR) groups tailored to support decision making within the Land Environment. Its mission is to prepare, force generate and deliver ISR capability in order to deliver success on operations. The Brigade will be a critical enabler throughout the continuum of engagement.

1st ISR Brigade became operational on 1 September 2014 and has responsibility for all British Army ISR capabilities.

The Brigade is comprised of 19 units: 14th Signal Regiment (Electronic Warfare) delivers a persistent ground based Electronic Warfare and Signals Intelligence capability.

5th Regiment Royal Artillery (RA) provides the Army’s Weapon Locating Radar, Medium and Heavy Ground-Based Intelligence Surveillance Target Acquisition and Reconnaissance capabilities. It also provides a battery of Surveillance and Target Acquisition (STA) patrols trained in Static Covert Surveillance.

The Honourable Artillery Company also provides STA Patrols and Light Ground-Based Intelligence and is paired with 5th Regiment RA.

32nd and 47th Regiments RA provide the Army’s Integrated Unmanned Aerial Systems (IUAS). Both Regiments are supported by 104th Regiment RA, which will operate the Watchkeeper UAS.

The three Regular and four Reserve Military Intelligence (MI) Battalions provide the full spectrum of MI capabilities to Land Forces. They provide a conduit into the Single Intelligence Enterprise to ensure that information is shared with Joint, Interagency, Intergovernmental and Multi-National capabilities.

MI Battalions are supported by the Weapons, Material and Personnel Exploitation capability. In addition, the Defence Cultural Specialist Unit provides linguists and cultural specialists. The Land Intelligence Fusion Centre delivers tactical intelligence reach-back for deployed forces.

The Specialist Group Military Intelligence is a unique nationally recruited pool of professionally trained Reservists whose expertise augments the Brigade’s MI capabilities.

Finally, the Brigade will field a number of specialist Human, Environment, Reconnaissance and Analysis patrols drawn from Reservist Units.
