Breaking it down
It spells E.T.S. using the chart: Echo (E), Tango (T), Sierra (S). ETS is the administrative date a service member’s contracted term of service ends.

ETS is a real, dated milestone in a military career, so the abbreviation was always going to get a phonetic form. Saying someone is “Echo Tango Sierra” is the spoken version of pointing at that date on the calendar.
How it is used
It describes a service member who is “short” — close to getting out and counting down to civilian life, terminal leave and veterans’ benefits. It carries a mix of envy and good-natured ribbing depending on who is saying it.
- Status: “He’s Echo Tango Sierra in three weeks — barely here anymore.”
- Planning: “Start your ETS paperwork early.” — the same idea, written out.
- Banter: Reminding a “short-timer” exactly how many days they have left.
