The first mech-inf regiment was constituted in 1969, and in the early days, existing battalions of premier infantry regiments (often, the first battalion of the regiment) like Madras, Sikh, Kumaon, Dogra and Jat as well as the Gorkha and Garhwal Rifles became mechanised. In fact, the first 14 battalions were all existing infantry battalions that were converted.
