"Nausena Medal (Hindi: \u0928\u094C\u0938\u0947\u0928\u093E \u092A\u0926\u0915, also spelt Nao Sena Medal or Nau Sena Medal, lit. Navy Medal) is a gallantry award for servicemen in the Indian Navy. It was established by the President of India, 17 June 1960. Obverse: The medal was originally described as a pentagonal silver medal, with concave edges, but it appears this design was never issued (except as specimens and miniatures?) and the design was altered in May 1961."@en . . .
