Just went to Buckley AFB w/my mum. I don’t know weapons and what they are called, but guard had big black one over his front. 100% ID check in place. I enjoy seeing our military armed like that. :) Wish we were more like Israel in that respect.
I know of a base where those guns are all empty. They have to make a requisition for bullets, which are not generally available or issued.
That might take awhile.
