Squadron Leader Ramanarayanan Ramesh (18735) AE (M) is posted to PHS with effect from 18 Mar 2000 on deputation to UN Peace Keeping Mission in Sierra Leone (UNAMSIL) as the Chief Engineering Officer and the Senior Technical Officer (Mi-8) of the IAF Contingent Sierra Leone-2000.

On 14 Jun 2000, Mi-8 helicopter Z-2356 developed Main Gear Box (MGB) abnormality during flight and force landed on a road near Rogberi. Post flight inspection revealed internal damage to the MGB and its change was the only option available to recover the helicopter. Rogberi was the last of the positions held by UNAMSIL, forces and remained under continuous rebel threat. Sqn Ldr RN Ramesh, along with the technical team moved by road to Rogberi on 15 Jun 2000 to undertake this daunting and challenging task. The MGB change was carried out in area where continuous exchange of gunfire between UNAMSIL troops and rebels was taking place. The task was made even more challenging by the incessant rain. Under the able guidance of Sqn Ldr RN Ramesh, the job was completed in less than two days enabling the helicopter to be recovered on 16 Jun 2000.

During 'Op Khukri' Sqn Ldr Ramesh undertook all the tasks assigned to him with great zeal and ardour. He set up a make shift DSS at Kenema within a couple of hours of his arrival there, thus facilitating the quick turn around of the aircraft between missions. He played a vital role in the success of the mission by ensuring 100% serviceability at all time. With his dedicated effort the Mi-8s flew 116 missions during the operation and all Mi-8 helicopters were readily available for any operational requirement.

For distinguished service of high order, the Hon'ble President is pleased to award 'Vishisht Seva Medal' to Squadron Leader Ramanarayana Ramesh.
