The Border Security Force (BSF) is a central armed police force in India under the Ministry of Home Affairs. It is responsible for guarding India’s borders with Pakistan and Bangladesh. It was formed in the wake of the Indo-Pak War of 1965 to ensure the security of India’s borders and for related matters.

The BSF has grown from 25 battalions in 1965, to 193 battalions with a sanctioned strength of 270,000 personnel including an expanding air wing, water wing, an artillery regiment and specialised units. It is currently the world's largest border security force. BSF has been termed the First Line of Defence of Indian territories.
