There are now three Army veterans on an indefinite hunger strike at Delhi's Jantar Mantar in protest against the delay in implementing One Rank One Pension or OROP. Retired Havildar Ashok Kumar Chouhan of the Signal Regiment this morning joined Col Pushpendra Singh (retd) of the 3 Grenadiers and Havaldar Major Singh of the 3rd Sikh Regiment in what they are calling a "fast unto death" at the venue of a two-month-long protest to demand OROP.
