[US Navy Vet]

The USAF Base I work(and retired from) on(OFFUTT/ACC) has not had Base Stickers for over 10 years. I am now sure how the rest of the DoD operates. You have to show your CAC or DoD ID to be admitted to the base.

I am DoD navy, the USN just rescinded this requirement recently. They're relying on CaC or some other form of military ID is required to enter. never heard anything about being a potential terrorism target.
