Mukti Bahini was a guerrilla force during the 1971 Bangladesh Liberation War. Made up of Bangladeshi military, paramilitary, and civilians, they fought to turn East Pakistan into independent Bangladesh. Led by General M. A. G. Osmani, they used hit-and-run tactics to control rural areas, often clashing with the Pakistan Army and its militias. They’re credited with helping India win the war but also accused of brutal acts against West Pakistanis and Biharis.
