context_page_description: Bangladesh's military history is intertwined with the history of a larger region, including present-day India, Pakistan, Nepal, Bhutan and Myanmar. The country was historically part of Bengal– a major power in South Asia and Southeast Asia.
  Muslims brought new military technology to the region after the 12th century. According to João de Barros, Bengal enjoyed military supremacy over Arakan and Tripura due to good artillery. Its forces possessed large guns and cannons. It was also a major exporter of gunpowder and saltpeter to Europe. Bengal had a cosmopolitan military, including Muslims, Hindus, Buddhists and mercenaries from Africa, Central and West Asia. The Bengal Sultanate was a powerful kingdom between the 14th and 15th centuries. Bengal became an integral part of the Mughal Empire in the 16th century. The Mughal Army built fortifications across the region and expelled Arakanese and Portuguese pirates from the northeastern coastline of the Bay of Bengal. Throughout the late medieval and early modern periods, Bengal was notable for its navy and shipbuilding. Its shipyards produced ships for the Mughal, Ottoman and British navies.
context_section_description: Following the victory of the Awami League in the 1970 elections, then-president General Yahya Khan refused to appoint its leader Sheikh Mujibur Rahman as the prime minister and launched a brutal attack named Operation Searchlight on the civilians of the then East Pakistan, using the Pakistani army to repress political movements. Figures of people killed by Pakistani forces vary from a minimum of around 300,000 to a maximum of around 3 million. Responding to Mujib's call for rebellion, many students, workers and other civilians mutinied against Pakistan and raised the Mukti Bahini, a guerrilla force. Later on, many Bengali officers and units from Pakistan Army and East Pakistan Rifles mutinied against their West Pakistani counterparts and joined the Mukti bahini. On 17 April 1971, Muhammad Ataul Gani Osmani took oath as the commander-in-chief of Mukti bahini. While the war raged on, the necessity of a well-trained armed force was always felt. During the first Bangladesh Sector Commanders Conference, held from 11 to 17 July 1971, the Bangladesh Forces was formed from the revolting Bengali members of the Pakistan Army and EPR. In this historic conference the field command structure, sector reorganization, reinforcement, appointment of field commanders and tactics of warfare were decided upon and carried out. On 21 November 1971, the Bangladesh Forces was divided into three separate services as Bangladesh Army, Bangladesh Navy and Bangladesh Air Force.
  The Bangladesh Forces received modest assistance from the Indian Government soon after the start of the war. On 3 December 1971, India-Pakistan war broke out and Indian troops enter Bangladesh allied with the Bangladesh Armed Forces. On 16 December 1971 the Pakistani Military force in Bangladesh surrender to a joint force of Indian and Bangladesh forces.
