The Westland Lynx AH.1 was used as a utility helicopter by the Army Air Corps. In 1982 655 Sqn based at Shackleton Barracks, Ballykelly, received their first Lynx to replace the Westland Scout to use in support of the Army and Royal Ulster Constabulary during operation Banner.
In this role the Lynx was usually fitted with nine seats and was used to deploy, and support foot patrols in the more rural areas. In late 1983 XZ666 was deployed to Lisanally Barracks in Omagh and used to support the RUC in the Omagh and Carrickmore areas. XZ666 known for obvious reasons as "Damien" was later converted to AH.7 standard and in 2008 was retired to DCAE Aborfield for use as a ground instructional airframe after flying more than 7,000 hours.
