His son lit the pyre in the presence of hundreds of people who had come to pay their last respects to the martyr.
A company of 9 Corps from Jalandhar gave a gun salute to the martyr at the crematorium.
Earlier, Sharma's body was brought to his native village by road as the Army could not airlift it due to inclement weather.
Sub-District Magistrate, Nadaun, Amit Mehra and local BJP MLA, Vijay Agnihotri were present at the time of cremation.
The entire nation and the BJP stand by them, he said.
