The 73 Armoured Regiment has the unique distinction of being raised during wartime, being formed on 3 December 1971, the day the Indo-Pak war broke out. It was raised at Vijay Lines, Ahmednagar, with a unique class composition of three martial communities - Sikhs, Rajputs and Qaimkhani Muslims. The first commanding officer was Lieutenant Colonel (later Major General) KM Dhody.
