One Rank One Pension (OROP), or "same pension, for same rank, for same length of service, irrespective of the date of retirement", is a longstanding demand of the Indian armed forces and veterans. The demand for pay-pension equity, which underlies the OROP concept, was provoked by the exparte decision by the Indira Gandhi-led Indian National Congress (INC) government, in 1973, two years after the historic victory in the 1971 Bangladesh war.
