The U.S. Navy recently released a photograph on social media showing a sailor firing his M-4 aboard a ship. No doubt some public relations officer thought the picture looked great—a fit and ready sailor shooting his rifle, with spent cartridges flying. A perfect picture for a recruitment catalog, except for one crucial detail: the rifle’s scope—which the sailor appears to be looking through—is mounted backwards, and its lens covers appear to be closed. A swift social media uproar arose over the bizarre and glaring error. Someone with actual military experience in the Navy evidently noticed what this photo said without words, because the picture was quickly deleted.
