Grit and experience affect the growth of an institution. Fighting four major wars, insurgency and other low intensity wars has indeed made the Indian Army an eminently and efficient battle trained, war machine. Changing times bring changing needs. Battle training must tell also on the structuring of the army, for it is this function that extracts the most from the assets available, both men and material.

The English raised the Territorial Army in 1920 through Indian Territorial Act of 1920 and it was comprised of two wings namely - 'The Auxiliary Force' for Europeans & Anglo-Indians, and 'The Indian Territorial Force' for Indian Volunteers. After Independence the Territorial Army Act was passed in 1948 and the first Indian Governor General Shri C. Rajagopalachari formally inaugurated the Territorial Army. It is celebrated with the Prime Minister's TA Day Parade every year.
