Dealers still have to keep printed "bound books" even if they use the e-4473 filing, and approved transactions result in the destruction of buyer information from what electronic records are created (we don't e-file for that reason - it's just a duplication of effort for us). Also, military IDs aren't by themselves sufficient to get a gun (neither is a passport, because neither establishes a state of residence). Further, giving your SS# on a 4473 is optional, so I don't see the problem, apart from giving your SS# to your captors, if it somes to that.
