Duty Status – Whereabouts Unknown (DUSTWUN) is a transitory casualty status assigned to United States servicemembers who cannot be located but have not been confirmed dead or captured.
A servicemember can have DUSTWUN status for only ten days.

US soldier Bowe Bergdahl came to national attention in the United States after spending five years in captivity in Afghanistan; he had left his post in 2009 intending to hike 20 miles to the closest command centre when he was captured by the Taliban.
His disappearance triggered an unsuccessful 45-day “DUSTWUN” manhunt by the US Army.
