A longstanding demand among the Indian armed forces and veterans, One Rank One Pension (OROP) means "same pension, for same rank, for same length of service, irrespective of the date of retirement". The demand can be traced back to the aftermath of the 1971 Bangladesh War. Later, the Rajiv Gandhi government under National Congres (I) decided to implement the policy of 'Rank Pay' that reduced the salaries of several rank officers like captains, colonels, majors, brigadiers etc relative to basic pay scales of civilian and police officers. The Third Central Pay Commission of 1986 also led to distrust among defence veterans. The decision affected thousands of defence officials as well as veterans. The resulting asymmetry between police and military rank officers led to nearly two decades of litigation and lingering mistrust between the government and veteran officers.
