where do I get a ID for Commissary privileges I am a 100% disabled Vet

If you have an issued DoD ID, it should be accepted at scan, when you checkout. There is always someone checking IDs at the entrance, or you can call them, and ask if the ID you have will work.

There is a DEERS ID center in the McGarity Reserve Center next to the commissary

You get a copy of your eligibility from the va just have them send it to you, go anywhere the?y issue id cards and you are set

Or the 911 base

at the community service center you need an appointment
