As has been discussed on this forum before, Federal Law prohibits firearms inside Federal facilities, but not generally on Federal property http://www.law.cornell.edu/uscode/718/usc_sec_18_00000930----000-.html. It is illegal to bring a gun inside a building on a base, but not into the parking area, etc. Some members have indicated that base commanders prohibit personnel from bringing firearms onto the base, however. My question is, for those of us not subject to UCMJ, can any legal sanction be imposed for violating the edict of a base commander?
