However, manning difficulties in the immediate post-war regular RAF led to a number of Fighter Control and Radar Reporting units of the RAuxAF being formed, from 1948 onwards. In the early and uncertain days of the Cold War, the Fighter Control and Radar Reporting units were largely responsible for manning the entire UK Control and Reporting system. All were disbanded by 1961. They were: 3500 (County of Kent) 3501 (County of Nottingham) 3502 (County of Antrim – later Ulster) 3505 (East Riding of Yorkshire) 3506 (County of Northampton) 3507 (County of Somerset) 3508 (County of Northumberland) 3509 (County of Stafford) 3510 (County of Inverness) 3511 (City of Dundee) 3512 (County of Devon) 3513 (City of Plymouth) 3602 (City of Glasgow) 3603 (City of Edinburgh) 3604 (County of Middlesex) 3605 (County of Warwick) 3608 (North Riding of Yorkshire) 3609 (West Riding of Yorkshire) 3611 (West Lancashire) 3612 (County of Aberdeen) 3613 (City of Manchester) 3614 (County of Glamorgan) 3617 (County of Hampshire) 3618 (County of Sussex) 3619 (county of Suffolk) 3620 (County of Norfolk) 3621 (North Lancashire) 3631 (County of Essex) Radar Reporting Units 3700 (County of London) 3701 (County of Sussex) The Regiment Squadrons In 1948, 20 RAuxAF Regiment Squadrons were proposed. In the event, 12 were formed in the Light Anti-Aircraft role, equipped with 40mm anti-aircraft guns and attached to the RAuxAF flying squadrons. By 1955, due to the introduction into service of more sophisticated weapons, the squadrons were converted to Regiment Field Squadrons. All 12 squadrons were disbanded, along with the flying squadrons, in 1957. However, three new field squadrons were re-formed in 1979, followed by two more in 1982 and a sixth in 1983. Since then, two have been disbanded and two have been re-roled. In addition, No 1339 Wing was formed in 1085 and consisted of 2729 and 2890 (both City of Lincoln Squadrons) equipped with Skyguard Raddar and Oerlikon guns both captured from the Argentinians during the 1982 Falklands War Both squadrons were disbanded in 1994 to become the Rapier Cadreisation Unit and then
