As a prior service Abrams tanker, I think many of these folks get too wrapped up in their favorite game and desire accuracy, forgetting that movies and video games commonly depict weapons and vehicles inaccurately on purpose. Even military uniforms in movies are commonly shown with improper set ups, insignia placements, etc. I imagine for contemporary vehicles, companies like gaijin get the basics available to the public and make some best guess adjustments. Just my thoughts.
