The Regiment was formed 1 April 1967 in Belfast by the amalgamation of 66 Signal Regiment (TA), 81 Signal Regiment (AER) and 302 Signal Squadron.[1] Due to the reduction in Territorial Army Royal Signals units, as a result of the Strategic Review of Reserves,[2] the regiment was disbanded on 31 March 2010. 66 Squadron and 69 Squadron were transferred to the command of 32 Signal Regiment.[3]
