How does the person putting up the post know whether that rifle was trained on anyone?

If I had that guy’s job*, I’d want to take the range to various landmarks in the vicinity so that if I ever did have to take a shot, I’d know ahead of time the range.

At least, that’s how the top Marine sniper from the second Gulf war told it.

Just because a guy is looking through the scope doesn’t mean he’s drawing a bead on a person.
