The basic role of the armed forces is to defend the country against external aggression and to protect it from internal threat when its ‘national security’ is jeopardised. Apart from carrying out these functions, in the seven decades of independence, the Indian Armed Forces have been actively participating in United Nations (UN) peacekeeping operations.

The ‘Lightning Campaign’ to liberate Bangladesh during the 1971 IndoPak War was one of the finest moments in Indian history. The ‘Battle of Garibpur’ fought on 21–22 November 1971, before the Indo-Pak War was officially declared on 3 December 1971, was a key battle in East Pakistan where a single infantry battalion, 14 Punjab (Nabha Akal) supported by a squadron of armour and intimate artillery support, successfully fought a Pakistani attack by infantry and armour.
