Border Security Force

The Border Security Force is a border defense agency of India. Its main duties are to defend the borders of India and to prevent transnational crimes. Under the administrative control of the Ministry of Home Affairs, the BSF is one of India's law enforcement agencies. The group is the largest border patrol force, consisting of 240,000+ personnel. After the Indo-Pakistani War of 1965, India lacked an adequate border defense agency leading to the formation of the Border Security Force. After the formation, the group participated in many conflicts including the Indo-Pakistani War of 1971, particularly the Battle of Longewala, and the Liberation of Bangladesh. Through these conflicts, the BSF later evolved into a counter-insurgency force.
