Raising in Parliament the matter of how the 8th battalion of Sikh Regiment got excluded from documentary on 20 years to Kargil, Congress MP Gurjeet Singh Aujla on Wednesday demanded an enquiry as to how this lapse took place. He sought action against those who took a decision. "The 8th Sikh is feeling hurt as they didn't figure in the 9-minute documentary made by the Army," said the MP, adding that the battalion had played key role in the capture of Tiger Hill.
