Param Vir Chakra (PVC)
Param Vir Chakra (PVC) is the highest gallantry award for officers and other enlisted personnel of all military branches of India for the highest degree of valour in the presence of the enemy. Introduced on 26th January 1950, this award may be given posthumously.
Literally, Param Vir Chakra means 'Wheel (or Cross) of the Ultimate Brave'. In Sanskrit, 'Param means Ultimate, 'Vir (Pronounced veer) means Brave and 'Chakra means Wheel.
If any recipient of the PVC shall again perform such and act of bravery as would have made him or her eligible to be recorded by a Bar to be attached to the riband by which the Chakra is suspended, and for every such additional act of bravery, an additional Bar shall be added, and any such Bar or Bars may also be awarded posthumously. For every Bar awarded a replica of the 'Indra's Vajra' in miniature shall be added to the riband when worn alone.
The PVC is the equivalent award of the Medal of Honour in the United States, and the Victoria Cross in the United Kingdom.
One amongst the luminous recipients of this honour was Flying Officer Nirmal Jiit Singh Sekhon, who was awarded the Param Vir Chakra posthumously in the year 1971. He is the lone Indian Air Force officer to have been honoured with the Param Vir Chakra till date.
