During the Bangladesh War of Independence, the Bangladesh Forces (not to be confused with Mukti Bahini) were divided in the geographical area of Bangladesh into eleven divisions designated as sectors. Each sector had a sector commander I.e. Division Commanders who directed the military operation further coordinated through several sub-sectors under sub-sector commanders who fought along with their troops and civilian resistance fighters. Most of the Sector Commanders and quite a number of sub-sector commanders remained in security under Indian BSF border camps such as Wing Commander Bashar, Major Shafiullah, Major Mir Shawkat Ali.
