 When the Army moved away from the Pentropic organisation in 1965 and the national service scheme began, there was an expansion of the reserve force and this saw a further three battalions being raised (the 4th, 17th, 41st), with the 19th Battalion formed in 1966 as a remote area battalion.A year after that, the 1st Battalion was reduced to a company, which was amalgamated with the 19th Battalion in 1971.Further amalgamations in 1987 led to the formation of the regiment as it is today.
