105th Regiment Royal Artillery

105th Regiment Royal Artillery, sometimes know as The Scottish & Ulster Gunners, is is part of the Army Reserve and has sub-units throughout Northern Ireland and Scotland. It is currently equipped with the L118 Light Gun.

History
The regiment was first formed as the 105 (Scottish) Air Defence Regiment Royal Artillery (Volunteers) on 1 April 1986 with its Regimental Headquarters at Artillery House, near Redford Barracks in Edinburgh. Its units were 207 (City of Glasgow) Air Defence Battery at Glasgow, 212 (Highland) Air Defence Battery at Arbroath and 218 (Lothian) Air Defence Battery at Livingston. It was equipped with the Starstreak missile. In 1987 219 (City of Dundee) Air Defence Battery was formed at Dundee and joined the regiment.

After the Options for Change defence review in 1993, 206 (Ulster) Battery transferred to the regiment from 102nd (Ulster) Air Defence Regiment. At that time 218 Battery and 219 Battery disbanded and the regiment was renamed 105 Regiment Royal Artillery (Volunteers).

Under Army 2020, a new battery, 278 (Lowland) Battery Royal Artillery based in Livingston will join this regiment.
