Second lieutenant is a junior commissioned officer military rank in many armed forces, comparable to NATO OF-1 rank.
Air vice-marshal (AVM) is a two-star air officer rank which originated in and continues to be used by the Royal Air Force. The rank is also used by the air forces of many countries which have historical British influence and it is sometimes used as the English translation of an equivalent rank in countries which have a non-English air force-specific rank structure. Air vice-marshals may be addressed generically as "air marshal".

General is the highest rank achievable by serving officers of the British Army. The rank can also be held by Royal Marines officers in tri-service posts, for example, General Sir Gordon Messenger the former Vice-Chief of the Defence Staff. It ranks above lieutenant-general and, in the Army, is subordinate to the rank of field marshal, which is now only awarded as an honorary rank. The rank of general has a NATO-code of OF-9, and is a four-star rank. It is equivalent to a full admiral in the Royal Navy or an air chief marshal in the Royal Air Force.
Australian Army officers receive a commission from His Excellency the Governor-General of Australia, who is also the Commander-in-Chief of the Australian Defence Force.

A five-star rank is the highest military rank in many countries. The rank is that of the most senior operational military commanders, and within NATO's standard rank scale it is designated by the code OF-10. Not all armed forces have such a rank, and in those that do the actual insignia of the five-star ranks may not contain five stars. For example: the insignia for the French OF-10 rank maréchal de France contains seven stars; the insignia for the Portuguese marechal contains four gold stars. The stars used on the rank insignias of various Commonwealth of Nations are sometimes referred to colloquially as pips, but are stars of the orders of the Garter, Thistle or Bath or Eversleigh stars depending on the wearer's original regiment or corps, and are used in combination with other heraldic items, such as batons, crowns, swords or maple leaves.
A four-star rank is the rank of any four-star officer described by the NATO OF-9 code. Four-star officers are often the most senior commanders in the armed services, having ranks such as (full) admiral, (full) general, colonel general, army general, or in the case of those air forces with a separate rank structure, air chief marshal. This designation is also used by some armed forces that are not North Atlantic Treaty Organisation (NATO) members.
An officer of three-star rank is a senior commander in many of the armed services holding a rank described by the NATO code of OF-8.

An officer of two-star rank is a senior commander in many of the armed services holding a rank described by the NATO code of OF-7. The term is also used by some armed forces which are not NATO members. Typically, two-star officers hold the rank of rear admiral, counter admiral, major general, divisional general, or in the case of those air forces with a separate rank structure, air vice-marshal.
Major general is a "two-star" rank in the British Army and Royal Marines. The rank was also briefly used by the Royal Air Force for a year and a half, from its creation to August 1919. In the British Army, a major general is the customary rank for the appointment of division commander. In the Royal Marines, the rank of major general is held by the Commandant General.
