The names of the fallen personnel will now be permanently inscribed at the National War Memorial in New Delhi.
Five of the personnel belonged to the Indian Army, while one served in the Indian Air Force.
Their names were included in the official list of military personnel who made the supreme sacrifice during various operations in 2025.
The six personnel who lost their lives during Operation Sindoor are Subedar Major Pawan Kumar, Rifleman Sunil Kumar, Lance Naik Dinesh Kumar, Agniveer Murali Naik, Havildar Sunil Kumar Singh and Indian Air Force Sergeant Surendra Kumar.
Their names will be engraved on the 'Tyag Chakra' (Circle of Sacrifice) at the National War Memorial, commemorating their service and sacrifice.
The Tyag Chakra consists of 16 concentric granite walls carrying the names, ranks and units of military personnel who have laid down their lives in service of the nation since India's Independence.

The government disclosed the names while publishing the list of all armed forces personnel who made the supreme sacrifice during various military operations in 2025.
This marks the first official release of the identities of those who lost their lives during Operation Sindoor.
Operation Sindoor
India launched Operation Sindoor on May 7 last year, targeting what it described as terrorist infrastructure in Pakistan and Pakistan-occupied Kashmir.
The military operation was carried out in response to the terrorist attack in Pahalgam, Jammu and Kashmir, in which 26 people were killed.
Pakistan responded with military action, leading to aerial engagements, drone attacks and heavy cross-border shelling.
The hostilities continued for four days before both sides brought the conflict to an end on May 10.
The operation was named "Operation Sindoor", a reference to the traditional red vermillion worn by married Hindu women.
According to the government, the name symbolised India's response to the Pahalgam terror attack, in which several women lost their husbands.
