The Army Act was enacted in parliament on the 10th of
October 1949 which is recognized as the day, the Ceylon
Army was raised. The Army was to be comprised of a Regular
and a Volunteer force and the initial requirement was
to raise the following units in the Regular and Volunteer
There were no formations and all units were directly functioning under Army Headquarters. Temporary field headquarters were formed at the time of a requirement as it was done during the 1958 communal riots. The first field formation was raised in 1963, to prevent illicit immigration from South India. This headquarters was known as Task Force Anti Illicit Immigration (TAFII), which was disbanded in 1981.
In May 1972, when Ceylon became the Republic of Sri Lanka, all Army units were renamed accordingly
