I worked security forces down the way at Nellis for a few years. I would say good luck getting in first of all, it’s just shitty desert for miles.
Second, when you cross into a restricted area which is clearly denoted by many posted signs or painted on the ground (when not dirt), lethal force is authorized no questions asked. But I would imagine that you would have to get in pretty far before lethal force is actually used.
I think people might actually show up but no one will actually do anything and it will be guards at the border of the restricted area talking to neck beards all night long.
