Overview

62 Res CIS Company, formally the 62 Reserve Field Communication and Information Services Company, was an Irish Reserve Defence Forces unit associated with the Communications and Information Services Corps. It was not a commercial brand or company in the ordinary business sense, but a military communications formation whose responsibilities were connected with field communications and information services. The unit's institutional lineage began in Dublin during the Emergency, Ireland's period of military mobilisation during the Second World War. In 1940, the 11 Field Communications Battalion of the Local Defence Forces was organised at 27 Parnell Square under Captain M. Egan. The battalion consisted of a headquarters company and seven additional companies. Its equipment included field telephone exchanges, signal lamps and D.3 cable, and its training focused on establishing and operating communications in field conditions. When the Local Defence Forces were disbanded on 31 March 1946, the battalion's wartime existence ended. The associated colours and historical identity were retained by the Permanent Defence Forces, while the reserve structure was reorganised under the newly established An Forsa Cosanta Áitiúil, commonly abbreviated FCA. On 1 April 1946, the formation re-emerged as 11 Field Signal Company FCA under Captain P. Walsh FCA. It initially comprised 44 members organised into four platoons and was based at Collins Barracks in Dublin. The company was integrated into the 6 Infantry Brigade and operated under Eastern Command. From 1959 it formed part of Eastern Command's 6th Brigade. During the early years of the Troubles in Northern Ireland, the unit assisted with communications and related support connected with the movement of refugees from Northern Ireland and completed a period of service on the border. Following the disbandment of 6th Brigade in 1977, it transferred to 2nd Brigade while remaining within Eastern Command. Later reforms of the Permanent Defence Forces combined the former Signal Corps with the Information Technology group to create the Communications and Information Services Corps. In that reorganisation, the reserve formation was re-established as 11 Field Communication and Information Services Company, reflecting the broader scope of communications and information technology responsibilities. With the creation of the modern Reserve Defence Forces from the FCA, the unit was again redesignated, becoming 62 Reserve Field Communication and Information Services Company. Its headquarters was at Cathal Brugha Barracks in Dublin. The formation was ultimately disestablished in April 2013, and its members were integrated into the associated Permanent Defence Forces unit, 2 Brigade CIS Company. Its historical significance therefore lies in its succession of Irish military reserve identities and its contribution to field communications, rather than in consumer branding, commercial sales or independent corporate activity.

History

The unit's lineage reaches back to 1940, when the 11 Field Communications Battalion was formed within Ireland's Local Defence Forces at 27 Parnell Square, Dublin. Captain M. Egan commanded the formation, which included a headquarters company and seven other companies. Its field-signalling role was supported by telephone exchanges, signal lamps and D.3 cable, with training designed around the deployment and operation of communications equipment outside fixed installations. The Local Defence Forces were dissolved on 31 March 1946 after the Emergency period. The battalion's pennant was transferred to the Permanent Defence Forces for safekeeping, while the reserve organisation was rebuilt through An Forsa Cosanta Áitiúil. On 1 April 1946, the formation returned as 11 Field Signal Company FCA under Captain P. Walsh FCA. It had 44 members arranged in four platoons and was located at Collins Barracks, Dublin. The company was attached to 6 Infantry Brigade and placed under Eastern Command, later becoming part of Eastern Command's 6th Brigade from 1959. The formation had a support role during the early Troubles, helping with communications and assistance connected with refugees arriving from Northern Ireland and undertaking a period of border service. When 6th Brigade was disbanded in 1977, the company moved to 2nd Brigade but remained under Eastern Command. A later Permanent Defence Forces reorganisation joined the former Signal Corps and the Information Technology group into the Communications and Information Services Corps. The reserve formation was consequently re-established as 11 Field Communication and Information Services Company, a name that recognised both traditional field communications and the expanding information-services function. When the Reserve Defence Forces were formed from the FCA, the unit became 62 Reserve Field Communication and Information Services Company. It was based at Cathal Brugha Barracks in Dublin. The unit was disestablished in April 2013. Its personnel were integrated into the associated Permanent Defence Forces formation, 2 Brigade CIS Company. This ended the independent existence of 62 Res CIS Company while continuing the service of its members within the Defence Forces' communications structure.
