From the very beginning till to date, the members who contributed in OCAS deserve profound regards from the current EX; Lest some names should missed unintentionally, all the names are not mentioned who worked hard for the OCAS. All of them deserve recognition from the present Executive Committee and indeed, it does. OCAS has passed a long way. Now it is the time for juvenile-energetic youth who are working hard and making the ground for the future committees to give it a mature shape like other successful ex-cadet associations.
