The roots of the Sri Lanka Artillery goes back to 1888, when on 20 April 1888 Ceylon Artillery Volunteers was formed as a gun battery under the command of Captain C.E.H Seimans of the Royal Artillery. During World War I Ceylon Artillery Volunteers was mobilised along with Town Guard Artillery of Colombo for the defence of Colombo. In 1918 the Ceylon Garrison Artillery (CGA) was formed by amalgamating the Ceylon Artillery Volunteers and Town Guard Artillery, coming under the Ceylon Defence Force. During the colonial period the main responsibility of the Ceylon Garrison Artillery was the coastal defence of Ceylon, by manning Coastal artillery batteries. During World War II CGA was deployed outside Ceylon to support the Allied and Commonwealth forces in the Indian Ocean as well as defending Ceylon. Equipped with 6 inch Guns the CGA was deployed in defence of Seychelles and the Cocos Islands.

In 1949 CGA became the Ceylon Artillery with formation of the Ceylon Army under the Army Act of 1949. That year the 1st Heavy Anti-Aircraft Regiment (HAA) of the Ceylon Artillery was formed under the command of Lieutenant Colonel (later Colonel) F.C. de Saram OBE. In 1953 it was renamed the 1st Light Anti-Aircraft Regiment (LAA), that same year the 3rd Field Artillery Regiment was formed. The 2nd Volunteer Coastal Artillery / Anti-Aircraft Regiment was formed in 1949, under the command of Lieutenant Colonel J.A.T. Perera ED, it was made up of officers and men of the Ceylon Garrison Artillery. In 1962 2nd Volunteer Regiment was disbanded and coastal artillery batteries decommissioned. The following year in 1963 the 1st Heavy Anti-Aircraft Regiment was amalgamated with 3rd Field Artillery Regiment and the 4th Regiment, Ceylon Artillery was formed, thus reducing the Ceylon Artillery to a single regiment. Years after amalgamation of the LAA, the air defence role of the Sri Lankan military was taken over by the Sri Lanka Air Force Regiment which it carries out to this day. The CA was renamed in 1972 as the Sri Lanka Artillery when Ceylon became a republic. Only in 1980 was a new volunteer regiment, the 5th (V) Artillery Regiment was formed.

At present the Sri Lanka Artillery has 12 regular regiments, 2 volunteer regiments a School of Artillery and a regimental band. Since the start of the Sri Lankan civil war in the 1980’s the SLA has provided fire support for all most all military operations carried out by the Sri Lanka Army against terrorists, it also performs the target acquisition role to locate enemy guns . At times the SLA has been deployed 4 reguler [RFT]and 2 vol regiments in an infantry role to meet the shortage of infantry.
