The first battalion of the regiment (1 Naga) was raised at the Kumaon Regimental Centre, Ranikhet on 1 November 1970 under the command of Lt. Col. R.N. Mahajan, VSM. Being the only battalion, it was then designated as the Naga Regiment. The manpower to raise this battalion was provided by battalions of the Kumaon Regiment, Garhwal Rifles and 3 Gorkha Rifles. 69 Nagas were enrolled directly from rehabilitation camps of underground Nagas. However, the regiment's troops were to be 50% Nagas and 50% of an equal number of Kumaonis, Garhwalis and Gorkhas. Since many Kumaon battalions had been associated with Nagaland, particularly in the years preceding the raising of the Naga Regiment, it was affiliated to the Kumaon Regiment for all regimental matters. The second battalion (2 Naga) was raised on 11 February 1985 at Haldwani.
