If you have a service related disability and it is on your VA ID. You just have to go to the visitors gate to register your ID and they will let you on base. The registration is good for 3 years. If you are going with a guest, they will have to go in too, but their pass is only good for 1 week and will have to do the 1 week pass every time
If you are retired military then no there's no need to sign up. If not retired, then I'm not sure if theres any procedure in place.
