In the
United States Army,
United States Air Force, and
United States Marine Corps,
general is a
four-star general officer rank, with the
pay grade of O-10. General ranks above
lieutenant general and below
General of the Army or
General of the Air Force; the Marine Corps does not have an established grade above general. General is equivalent to the rank of
admiral in the other
uniformed services. Since the grades of General of the Army and General of the Air Force are reserved for war-time use only, and since the Marine Corps has no five-star equivalent, the grade of general is currently considered to be the highest appointment an officer can achieve in these three services.
