The Biplobi Shainik Sangstha (Bengali: বিপ্লবী সৈনিক সংস্থা, lit.'Organisation of Revolutionary Soldiers') was a clandestine revolutionary socialist group of sepoy mutineers within the Bangladesh Army, active from 1973 to 1975. The BSS was formed by the vanguard socialist-revolutionary party Jatiya Samajtantrik Dal (JaSaD) and led by Maj. M.A. Jalil and Lt. Col. (retd.) Abu Taher. The BSS is known for staging the 7 November 1975 coup through the Sipahi–Janata Revolution, which would eventually make way for the rise of Lt. Gen. Ziaur Rahman in the country's politics.
