The answer is possibly yes. Appendix Q of the Joint Federal Travel Regulations lists minimum OCONUS tour lengths. Generally speaking, the minimum overseas tour length is 36 months accompanied and 24 months unaccompanied. Time creditable on an overseas tour begins with the day of departure from CONUS and ends with the day of return. For members taking leave outside the continental U.S. (OCONUS), the area tour will commence upon termination of leave. Please check with your detailer and see specific service instruction for more information.
