31st (City of London) Signal Regiment
The 31st (Greater London) Signal Regiment was a territorial communications regiment of the British Army's Royal Corps of Signals. The regiment first formed following the creation of the Territorial and Army Volunteer Reserve in 1967 after the 1966 Defence White Paper. After seeing limited reserve support during the Cold War, the regiment was disbanded in 2010 following the initial Army 2020 reform. History 
Following the announcement of the 1966 Defence White Paper, new "large" regiments and formed within the new Territorial and Army Volunteer Reserve. Although more focused on the infantry corps and royal artillery, the royal corps of signals did see some changes including new TA regiments. On 1 April 1967 the 31st (Greater London) Signals Regiment was formed from with the following regiments being the "parent" units;

 41st (Princess Louises's Kensington Regiment) Signal Regiment (TA) becoming 41 Squadron
 47th (The Duke of Cambridge's Middlesex Hussars (Yeomanry)) Signal Regiment (TA) becoming 47 Squadron
 83rd (East Anglian) District Signal Regiment (AER) becoming 83 Squadron (kept Army Emergency Reserve number)

After formation the regimental headquarters were located at Hammersmith where they would remain for almost 30 years. After organising the regiment was assigned to the 11th Signal Group (V) as the reserve trunk communications signal regiment for SHAPE. By 1992 the regiment was moved under control of the 2nd (National Communications) Signal Brigade and provided communications for the City of London and general County of London area. In 1994 the regimental headquarters moved to Southfields where it remained until disbandment. During this period, the regiment had links with the Worshipful Company of Innholders and the London University Officer's Training Corps. During the initial Operation Telic invasion, volunteers of the regiment served in Iraq with their regular counterparts. In 2010 the regiment was disbanded following the concurrent disbandment of the 2nd Signal Brigade and the re-organisation of the TA signals as a result of the Army 2020 reform. Although the RHQ was disbanded, all squadrons' titles, lineages, and roles were all retained, with most squadrons moving to the other London signals regiment, 71st (City of London) Yeomanry Signal Regiment (V).
