Currently, law enforcement officers have the ability to carry a concealed weapon without regard to state lines or local ordinances.
Military personnel have the same, if not more, training concerning weapons handling and conflict resolution. If military members can be trusted to represent the US on the world stage while armed, we should be able to protect ourselves and those around us at home. Military personnel are always on the move and for those who wish to uphold their 2nd amendment right, it is difficult to do so when being ordered to move state to state.
That same confidence granted to us overseas should be given domestically so that we can continue to serve and protect our fellow citizens.
