which all subaltern officers are classed as OF-1 (O-1 and O-2 in US). O-11 is sometimes used for the U.S. OF-10 ranks, but this is not official. OF-10 ranks in the United States can only be attained during wartime; the last five-star officer died in 1981. This is also now generally the case in the UK, although provision is made to award them under special circumstances in peacetime (No promotion to these ranks has been made since they were generally suspended in 1997, with the exception of the honorary promotion of Lord Boyce to Admiral of the Fleet in the Queen's 2014 birthday honours.) Captain-General Royal Marines is a ceremonial rank, usually held by a member of the royal family (such as Prince Harry, Duke of Sussex). There is no field marshal rank in the Royal Marines, although Royal Marine officers may reach full general rank. Due to their modern-day size, the ranks of general and lieutenant-general are not used within 3 Commando Brigade or the main Royal Marines. The position of commandant general is held by a major-general. Royal Marines officers may hold the rank of lieutenant-general, serving in Ministry of Defence or joint forces positions. Royal Marine officers may reach the full rank of general, for example General Gordon Messenger. At various times (1775-1981) the O-7 rank in the USN has been called Commodore and briefly once, Commodore Admiral. Then changed to Rear Admiral lower half due to Captains and Commanders that commanded more than 1 ship or squadrons given the title, but not rank, of Commodore. The rank of Ensign is not used in the Royal Marines. Royal Marines officers join as second lieutenants; after two years of service, provided that Phase 2 training has been successfully completed, they are promoted to the rank of lieutenant (if under 21 at the time of joining) or captain (if 21 or older at the time of joining). The rank of Ensign is no longer used in the Royal Navy. All officers now join BRNC Dartmouth as midshipmen once more, unless they have previously served in the ranks ((senior) upper yardsmen) but use the non-substantive rank of officer cadet (OCdt) during the pre-initial sea phase. The name for Officers in training for the US Navy vary depending on the particular officer commissioning program. Naval Academy, Merchant Marine Academy and NROTC are midshipmen (MIDN); United States Coast Guard Academy are cadets;
