The Border Security Force (BSF) is a border guarding force of the Government of India. Established on December 1, 1965, it is one of the Central Armed Police Forces. Its primary role is to guard India's international borders during peacetime and also prevent trans-border crime. Like all Central Armed Police Forces of India, the BSF is under the administrative control of the Ministry of Home Affairs. It is one of the many law enforcement agencies of India. With a strength of 240,000 personnel in 186 battalions, including women personnel, it is one of the world's largest border patrol forces. Different types of unexpected situations may occur at the border—peacetime, less than the wartime. To manage the situations arising at borders effectively, a group of people, mainly the military or the police, are under the duty to keep a watch over the area at regular intervals of time to corroborate peace and safety. India follows the principle of ‘One Border, One BorderGuardian Force'. In the context of this principle, the burden of the India-Pakistan, and India-Bangladesh border is under the hands of the Border Security Force (BSF), Assam Rifles (AR) for the India-Malaysian border, and Indo-Tibetan border police for the India-China border. Nepal and Bhutan’s border is overlooked by Sahsastra Seema Bal (SSB).
