"Government is hell bent on short changing. There are only three points of contention," a key functionary of the ex-servicemen community said.
The government wants 2011 to be the base year besides no three per cent annual increase, he said, adding it also wants payment to begin from April 1, 2015 as against the agreed date of April 1, 2014.
"We have rejected the proposal. Escalation of our protest in expected. The complicated arithmetic will mean reduced payout," he said.
The meeting was attended by Home Minister Rajnath Singh, Finance Minister Arun Jaitley, Defence Minister Manohar Parrikar, Parliamentary Affairs Minister M Venkaiah Naidu and Shipping Minister Nitin Gadkari.
Meanwhile, two more joined the fast-unto-death today. They were retired Navy commander A K Sharma and Sanwal Ram Yadav, father of martyr Lance Naik Sunil Kumar Yadav.
Army chief Gen Dalbir Singh Suhag had last night held a two-hour long meeting with representatives of ex-servicemen.
It was speculated that the government might announce OROP on August 28, the 50th anniversary of 1965 war with Pakistan.
Close to 22 lakh retired servicemen and over six lakh war widows stand to be the immediate beneficiaries of the scheme, which envisages a uniform pension for the defence personnel who retire in the same rank with the same length of service, irrespective of their date of retirement.
Currently, the pension for retired personnel is based on the Pay Commission recommendations of the time when he or she retired. So, a Major General who retired in 1996 draws less pension than a Lieutenant Colonel who retired after 1996.
