The Special Frontier Force (SFF) is an Indian special operations unit created on 14 November 1962. It mainly comprised Tibetan refugees living in India. Now it has increased in size and scope of operations. Its primary goal originally was to conduct covert operations behind Chinese lines in the event of another Sino-Indian War. Throughout its history, SFF has fought in India's major external wars including the Bangladesh Liberation War and the Kargil War. It has also been involved in internal security, including Operation Blue Star and also serving as the "Personal Force" of Prime Minister Indira Gandhi to suppress opposition parties during the state of emergency from 1975 to 1977. It has been part of border operations against China, including the 2020 China–India skirmishes.
