The real question is why is everyone at a military base unarmed?
That was a decision made by Snopes Clinton, who hated the military, the Second Amendment, and all us commoners who believe it means exactly what it says. Take it from there.
Actually, the policy was put in place by George H. W. Bush. The Senior Bush was reiterating an existing policy dating back to the end of WWI.
