DEROS stands for Date eligible for return from overseas, a military term abbreviation.

Date on which a service member's overseas tour ends and the member may return to the United States. The term was especially familiar during the Vietnam War, when tours were generally one year.

Example: Every grunt in the platoon counted the days to his DEROS on a calendar drawn on his helmet cover.

Usage notes

Pronounced "DEE-ros." Vietnam-era soldiers kept "short-timer" calendars counting down to DEROS. The term is still used in Army and Air Force personnel systems for overseas tour end dates, especially in Korea and Europe.
