This thread is fascinating on a number of levels... be surprised when you sign up for a base access check and they actually pull your record, I guess.
Would that "daily pass" still need a bg check?
i can't imagine there is any material difference between the service branches, but USAF 'base passes', you go to the visitor center (not at a gate, but usually annexed by one) and request one for 1-30 days; which automates a background check. commercial-licensed vehicles (ie dudes delivery furniture, company contractors etc) get directed to a specific location and get a vehicle search and an on the spot background check. in either case, you're getting a full pull on your id; having seen what it looks like it shows literally everything crime-related, i've seen stuff from 80s on people, stuff like traffic violations as well as sexual assault or DUIs.
if you forget your DOD ID, special vendor ID or don't have a visitor base pass when you try to enter, you're directed to the visitor center. they will either verify your ID via fingerprint (DOD dudes) or run a background check and issue one to you, the latter only happens if you're 'sponsored' by a DOD card holder (retirees, active duty, civil servants etc)... I've seen people get 'sponsored' only to get rejected due to drug/whatever offenses on your background check, the relevance of which depends on the severity and type of crime and local base policy. ex where I'm at any sexual assault conviction is an automatic no regardless of how long ago it happened, while DUIs are given a 5 year window iirc.

also state and local laws mean nothing; assuming weed being legal in your state means you can roll onto the local military base with a joint in your bag will get you nothing but disappointment... i've seen delivery drivers get permanently barred from entry because of this multiple times in MA.
