election supervision, guarding vital installations and counter-naxal operations. The Indo-Pakistani War of 1965, which highlighted the inadequacy of the existing border-management system, led to the formation of the Border Security Force as a unified central armed police force mandated with guarding India's boundary with Pakistan. The BSF's policing capability was used in the Indo-Pakistani War of 1971, against the Pakistani Armed Forces, in areas which were the least threatened. During wartime or when ordered by the central government, the BSF is commanded by the Indian Army; BSF troops participated in the 1971 Battle of Longewala in this capacity. After the 1971 war (which led to the creation of Bangladesh), responsibility for policing the border with Bangladesh was assigned to the force. Originally charged with guarding India's external borders, the BSF has been tasked with counter-insurgency and counter-terrorism operations. When insurgency in Jammu and Kashmir broke out in 1989 and the Jammu and Kashmir state police and the thinly-deployed Central Reserve Police Force (CRPF) needed extra force to cope with spiraling violence, the central government deployed the BSF to Jammu and Kashmir to combat Kashmiri militants. BSF operates a Tear-Smoke Unit at its academy in Gwalior, Madhya Pradesh, which supplies tear gas and smoke shells for riot prevention to all state police forces. It operates dog squads, and runs the National Dog Training and Research Centre. The BSF, one of several Indian police forces which have its own air and water wings, provides helicopter, dog and other support services to the state police. Central Industrial Security Force The Central Industrial Security Force's (CISF) primary task is to provide industrial security. It guards industrial installations nationwide which are owned by the central government, secures seaports and airports, and provides security for certain non-governmental organizations. The CISF provides security for nuclear-power plants, space installations, mints, oil fields and refineries, heavy-engineering and steel plants, barrages, fertilizer units, hydroelectric and thermal power stations, and other installations partially (or wholly) run by the government. Central Reserve Police Force The Central Reserve Police Force's (CRPF) main objective is to assist states and union territories' law-enforcement agencies in maintaining law and order and containing insurgency. It is deployed as an anti-terrorist unit in several regions, and operates abroad as part of United Nations peacekeeping missions. Indo-Tibetan Border Police The 90,000-member Indo-Tibetan Border Police (ITBP) is responsible for security along the Indo-Tibetan border and its surrounding areas. ITBP personnel
