The main purpose of this legislative proposal is to change the rules regarding members of the Armed Forces carrying personal firearms on military installations. It aims to make it easier for service members to have their own firearms with them while on base, particularly when they are not on duty. The key provisions of this proposal include establishing a rebuttable presumption in favor of allowing service members to carry their personal firearms on military property. This means that the default position will be that they can carry their firearms unless there is a specific reason not to.
