A general officer is an officer of high rank in the armies, and in some nations' air forces, space forces, and marines or naval infantry.
Field marshal is the second most senior military rank, ordinarily senior to the general officer ranks, but junior to the rank of Generalissimo. Usually, it is the highest rank in an army, and as such, few persons are ever appointed to it. It is considered as a five-star rank (OF-10) in modern-day armed forces in many countries. Promotion to the rank of field marshal in many countries historically required extraordinary military achievement by a general. However, the rank has also been used as a divisional command rank and also as a brigade command rank. Examples of the different uses of the rank include Afghanistan, Austria-Hungary, Pakistan, Prussia/Germany, India and Sri Lanka for an extraordinary achievement; Spain and Mexico for a divisional command ; and France, Portugal and Brazil for a brigade command.
Generalfeldmarschall was a rank in the armies of several German states and the Holy Roman Empire (Reichsgeneralfeldmarschall); in the Habsburg monarchy, the Austrian Empire and Austria-Hungary, the rank Feldmarschall was used. The rank was the equivalent to Großadmiral in the Kaiserliche Marine and Kriegsmarine, a five-star rank, comparable to OF-10 in today's NATO naval forces.
Air marshal is an air-officer rank used by some air forces, with origins from the Royal Air Force. The rank is used by the air forces of many countries which have historical British influence, including many Commonwealth nations. The rank is usually equivalent to a vice admiral or a lieutenant general.
Grand admiral is a historic naval rank, the highest rank in the several European navies that used it. It is best known for its use in Germany as Großadmiral. A comparable rank in modern navies is that of admiral of the fleet.
Marshal of the air force or marshal of the air is a five-star rank and an English-language term for the most senior rank in some air forces.

Ettore Bastico was an Italian field marshal who served as the commander of Axis forces in North Africa from 1941 to 1943 during World War II.

After his time in the army, he became a military historian and published several books.
An army corps general or corps general is a rank held by a general officer who commands an army corps. The rank originates from the French Revolutionary System, and is used by a number of countries. Normally, the rank is above the divisional general and below the army general, so it usually corresponds to the lieutenant general. However, in some countries such as Spain, Brazil, and Peru, the rank of army corps general is not used, in Spain the rank of army corps general is replaced by the rank of lieutenant general, while in some countries such as Brazil and Peru, the rank of army general is immediately above that of divisional general.
Divisional general is a general officer rank who commands an army division. The rank originates from the French Revolutionary System, and is used by a number of countries. The rank is above a brigade general, and normally below an army corps general.
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 various Commonwealth of Nations rank insignias are sometimes colloquially referred to as pips, but in fact either are stars of the orders of the Garter, Thistle or Bath or are 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.
The Royal Italian Army (RE) was the land force of the Kingdom of Italy, established with the proclamation of the Kingdom of Italy. During the 19th century Italy started to unify into one country, and in 1861 Manfredo Fanti signed a decree creating the Army of the Two Sicilies. This newly created army's first task was to defend against the repressive power in southern Italy, exemplified by rulers like Francis II of the Two Sicilies. The Army of the Two Sicilies combated against outlaws and against other armies during this time of unification. After the monarchy ended in 1946, the army changed its name to become the modern Italian Army.

The Italian Co-belligerent Army, or Army of the South were names applied to various division sets of the now former Royal Italian Army during the period when it fought alongside the Allies during World War II from October 1943 onwards. During the same period, the pro-allied Italian Royal Navy and Italian Royal Air Force were known as the Italian Co-belligerent Navy and Italian Co-belligerent Air Force respectively. From September 1943, pro-Axis Italian forces became the National Republican Army of the newly formed Italian Social Republic.
