A United States Navy enlisted rate indicated where an enlisted Sailor stood within the chain of command, and also defined one's pay grade. An enlisted sailor's rate was similar conceptually to a naval officer's rank. Only Naval Officers carry the term "rank" in the Navy. The word rate refers to an enlisted sailor's pay grade, while the word rating refers to one's area of occupational specialization within the enlisted Navy. Associated with the enlisted pay grades is a numbering system from the most junior enlisted sailor ("E-1") to the most senior enlisted sailor ("E-9"). This enlisted numbering system is the same across all five branches of the U.S. Military. All E-1 through E-3 will now be known as Seamen. E-4 through E-6 will be called Petty Officers. All E-7s will be called Chief Petty
