Cyber and Electro Magnetic Activities Effects Group
The Cyber and Electro Magnetic Activities Effects Group (CEMA Effects Group) is a combat support formation of the British Army due to form by late 2022. The group will bring together three specialist regiments of the Royal Corps of Signals under Commander Field Army. History 

As part of the Army 2020 and subsequently Army 2020 Refine programmes, the 14th Signal Regiment (Electronic Warfare) under control of the 1st Intelligence, Surveillance and Reconnaissance Brigade (6th (UK) Division), while the 13th Signal Regiment was formed in June 2020 under 1st (UK) Signal Brigade (6th (UK) Division) as the first dedicated cyber unit. The last regiment, 21st Signal Regiment was under 7th Signal Group, part of 11th Signal Brigade and Headquarters West Midlands (1st (UK) Division, later 3rd (UK) Division).
