The former soldiers have threatened to go an a relay hunger strike from tomorrow.
The protest comes after talks -- both formal and back- channel -- with the government failed as the ex-servicemen were not given a specific timeline for the implementation of the long-pending OROP.
"Prime Minister Narendra Modi has assured us that it will be implemented, but it has been one year," said Col. (retd) Anil Kaul, the media advisor to Indian Ex-Servicemen Movement (IESM).
The ex-servicemen maintained that they were not against any government but are protesting to get their long-pending dues. They also said that they have sought an appointment with the President Pranab Mukherjee to take up this matter.

Interestingly, some farmers' groups and students from Delhi University and Jawaharlal Nehru University also joined the protests today.
The slogan of 'Jai Kisan, Jai Jawan' was raised as a group of farmers joined the protest at Jantar Mantar here to support the ex-servicemen.
In the eighth instalment of his 'Mann Ki Baat' radio talk, Modi had assured ex-servicemen that his government would soon resolve the OROP issue.
OROP envisages a uniform pension for the defence personnel retiring in the same rank with the same length of service, irrespective of their date of retirement.
Close to 22 lakh ex-servicemen and over six lakh war widows stand to be the immediate beneficiaries of the scheme.
Even though the government has said it is committed to implementing OROP, there has been no official clarification on why the scheme is getting delayed.
