The "Indianisation" of the British Indian Army began with the formation of the Prince of Wales Royal Indian Military College at Dehradun in March 1912 with the purpose of providing education to the scions of aristocratic and well-to-do Indian families, and to prepare selected Indian boys for admission into the Royal Military College, Sandhurst.Indian officers were given a King's commission after passing out and were posted to one of the eight units selected for Indianisation.Other major operations undertaken by the army include: Operation Vijay, Operation Meghdoot and Operation Cactus.
It is a major component of national power alongside the Indian Navy and the Indian Air Force.
The army has been involved in four wars with neighbouring Pakistan and one with China.
The Indian Army has a regimental system, but is operationally and geographically divided into seven commands, with the basic field formation being a division.
It is an all-volunteer force and comprises more than 80% of the country's active defence personnel.
The primary mission of the Indian Army is to ensure national security and national unity, defending the nation from external aggression and internal threats, and maintaining peace and security within its borders.
