A Casualty Assistance Calls Officer (CACO) is the official representative of the Secretary of the Navy who provides information, resources and assistance to the PNOK and SNOK in the event of a casualty. Their full time responsibility and mission is to assist families during a difficult time and ensure they receive the benefits and entitlements due. CACO duties are varied and are dependent upon the status of the Sailor at the time the casualty occurs (i.e. Death, Where-abouts Unknown (DUSTWUN), Missing, Ill, or Injured).
