There are no generals in the Navy. The navy has admirals. The full compliment of officers varies with promotions and retirements.
As of 2005 the armed forces released there were currently 86 "Major Generals" (2 star). However specific names are generally withheld outside of 4-5 star generals for security purposes.
As stated in the United States Code, the number of four star generals has a limit in every department. For the US Army, the maximum is 230, Air force totals to 208, and for the Marine Corps is 60.
A 5 star general in the Marine Corps would be called an imposter because there is no such person. The generals in the USMC are Brigadier General ( 1 star ) Major General ( 2 star ) Lieutenant General ( 3 star ) and General ( 4 star ). There is no 5 star general in the USMC. The general who outranks a 4 star general is the Commandant of the Marine Corps but is himself a General ( 4 star ). He is outranked by the Secretary of the Navy and is a member of the Joint Chiefs of Staff.
