The second and third-highest peacetime gallantry awards - Kirti Chakra and Shaurya Chakra - were on Wednesday conferred to seven bravehearts of the defence forces posthumously, including Colonel Manpreet Singh and Deputy Superintendent of police Himayun Muzzammil Bhat, who laid down their lives in an anti-terror operation in Jammu and Kashmir's Anantnag in September last year.
