What is military etiquette?

Military etiquette is the set of courtesies and customs that are peculiar to the military. They cover a broad range, and provide the protocol to follow when addressing, working with and socializing between senior and subordinate military personnel. They range from the simple; addressing other military members by their rank instead of first names and when and how to salute, to the complicated; how many saluting guns, ruffles and flourishes to play for visiting dignitaries and how to sit in rank order when occupying a small boat. A book is provided to each junior officer at commissioning with the complete rules of military etiquette.
