Under the Army 2020 programme, a larger emphasis was placed on cyber and specialist capabilities.

As part of this reorganisation, the 1st Military Intelligence Brigade, the Royal Artillery's UAS regiments, Honourable Artillery Company and the two reserve Special Air Service (SAS) Regiments came under the command of the newly formed 1st Intelligence Surveillance and Reconnaissance Brigade.

The new brigade was stood up on 1 September 2014 at Upavon and placed under Force Troops Command.

[1][2] Under the Future Soldier programme announced on 25 November 2021, the brigade was reduced to a Colonel's Command, became the Intelligence, Surveillance, and Reconnaissance Group[3] and transferred from the now disbanded 6th Division to Field Army Troops.
