The Bangladesh Armed Forces have inherited the institutional framework of the British military and the British Indian Army. It was formed in 1971 from the military regiments of East Pakistan. In 2018, the active personnel strength of the Bangladesh Army was around 157,500, excluding the Air Force and the Navy (24,000). In addition to traditional defence roles, the military has supported civil authorities in disaster relief and provided internal security during periods of political unrest. For many years, Bangladesh has been the world's largest contributor to UN peacekeeping forces. In February 2015, the country made major deployments to Côte d'Ivoire, Cyprus, Darfur, the Democratic Republic of Congo, the Golan Heights, Haiti, Lebanon, Liberia and South Sudan.
