King of Chevron
This line most likely means to give priority, importance, or rank. Like a National Anthem is of great importance to US society, so is the Chevron in its military. A Chevron is a type of insignia in the form of an inverted V-shape, commonly used to express rank in the US Military. Therefore, given the American patriotic references of the song, is most likely the intended association for American listeners.
It may also be reference to the oil mega-corporation, Chevron, which is known as a powerful worldwide company built on American wealth and capitalism.
