The military now does 100 percent ID checks, and your ID is scanned by gate guards. If your ID card is not in the database, you are sent to the visitors center where your information is entered into DoD computers. It's been this way for several years on Air Force installations. Stickers were not much of a security deterrent, frequently cars were sold with the stickers still attached to civilians who had no business on the base. Think about such a vehicle getting into the hands of terrorists. Better to check the bona fides of the driver and occupants with a 100 percent ID check than to wave a car or truck through because it has a current base sticker. When I took my car overseas for a military assignment, those stickers were scraped off as a matter of course anyway. It was a sure fire way for the bad guys to know that the car belonged to a service member.
