The Mechanised Infantry Regiment is an infantry regiment of the Indian Army, comprising 27 battalions dispersed under various armoured formations throughout India. It is one of the youngest regiments in the army, and though it was formed as a result of lessons learned in the 1965 Indo-Pak War, to give infantry battalions greater mobility, it was the mastermind of Gen Sundarji who had the foresight to cater the needs of a modern army. Initially, some of the older infantry battalions of various regiments were equipped with the BMP-1 armoured personnel carriers. The need for something more concrete and viable was felt along with a need to develop a common philosophy with regards to the type of tactics. This necessitated the raising a totally new arm in the Indian Army, resulting in the various mechanised battalions being brought together under a single cap badge as the Mechanised Infantry Regiment in 1979.
