Can you use your GTCC when you ETS?

No. Typically they'll cut that up right before you get out to ensure you don't use it.

If you've cleared properly, it shouldn't work...

When you ETS, one of your stops is your Battalion S-8. Your S-8 will check to see if you have an open GTCC account open and will require that you close your account and turn in your card before they sign your paper. When you turn in your GTCC, they **should** cut it or shred it in front of you.

If you're asking if you can use it through the process of ETSing, you shouldn't. There shouldn't be anything that's needed when ETSing. GTCCs are for official travel expenses between duty stations only.
