Military weapons contain references to Bible verses. Why do people still deny that the War is a Crusade?

Trijicon (they make optics for civilians and military) is a Christian owned company. They put this on all of their optics. It is just an abbreviation after the model number (like JN8:12). 99% of people that own or use these optics would not even know what it was if they were looking at it. To say that this is proof that the current war is a "Crusade" is about the most retarded thing I have ever heard.
