"The Navy’s rate and rank structure for men and women on active duty is similar to the rate and rank
structure used by the cadets in the NJROTC program. Enlisted personnel have rates, and commissioned
officers have ranks. An officer’s rank refers to his or her official title (e.g., ensign, lieutenant commander,
captain, etc.), but it also indicates the monthly pay. Enlisted personnel have similar
titles and pay grades."
When you Rank up you will be ranked up by CADET Rates Or Ranks. You will first start as enlisted and then will move up until you are an officer. To rank up you need to know your knowledge and be considered worthy to move up. You will have to memorize Navy Enlisted and Officer Ranks and Rates and also the Marine Ranks and Rates.
