A general officer is an officer of high rank in the armies, and in some nations' air and space forces, marines or naval infantry.
Military ranks are a system of hierarchical relationships within armed forces, police, intelligence agencies and other institutions organized along military lines. Responsibility for personnel, equipment and missions grow with each advancement. The military rank system defines dominance, authority and responsibility within a military hierarchy. It incorporates the principles of exercising power and authority into the military chain of command—the succession of commanders superior to subordinates through which command is exercised. The military chain of command is an important component for organized collective action.
Field marshal is the most senior military rank, senior to the general officer ranks. 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.
The following table shows comparative officer ranks of several Allied and Central powers during World War I.
Listed in the table below are the insignia—emblems of authority—of the British Army. Badges for field officers were introduced in 1810 and the insignia was moved to the epaulettes in 1880. On ceremonial or parade uniforms these ranks continue to be worn on the epaulettes, either as cloth slides or as metal clips, although on the modern 'working dress' they are usually worn as a cloth slide on the chest. Although these insignia apply across the British Army there is variation in the precise design and colours used and it can take some time to become familiar with them all.
Feldwebel is a non-commissioned officer (NCO) rank in several countries. The rank originated in Germany, and is also used in Switzerland, Finland, Sweden, and Estonia. The rank has also been used in Russia, Austria-Hungary, occupied Serbia and Bulgaria.
Rank insignia in the French Army are worn on the sleeve or on shoulder marks of uniforms, and range up to the highest rank of Marshal of France, a state honour denoted with a seven-star insignia that was last conferred posthumously on Marie Pierre Koenig in 1984.
The military ranks of Finland are the military insignia used by the Finnish Defence Forces. The ranks incorporate features from the Swedish, German, and Russian armed forces. In addition, the system has some typically Finnish characteristics that are mostly due to the personnel structure of the Finnish Defence Forces. The ranks have official names in Finnish and Swedish languages and official English translations. The Swedish forms are used in all Swedish-language communications in Finland, e.g. in Swedish-speaking units of the Finnish Defence Force. The system of ranks in the Swedish Armed Forces is slightly different.
General is the highest rank of the German Army and German Air Force. As a four-star rank it is the equivalent to the rank of admiral in the German Navy.
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, Generals Sir Gordon Messenger and Gwyn Jenkins, former and current 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.
The Paraguayan Army is the ground force branch of the Armed Forces of Paraguay. It is organized into three corps and nine divisions, and several commands and direction. It has gone to war on many occasions, notably in the War of the Triple Alliance (1864–1870) against Brazil, Argentina and Uruguay; the Chaco War against Bolivia; and the ongoing Paraguayan People's Army insurgency.
The military ranks of the Soviet Union were those introduced after the October Revolution of 1917. At that time the Imperial Russian Table of Ranks was abolished, as were the privileges of the pre-Soviet Russian nobility.
In the Finnish Defence Forces, Field Marshal is officially not an active military rank but an honorary rank that can be bestowed upon 'especially distinguished generals'. So far the only holder of this title has been Baron Carl Gustaf Emil Mannerheim, then Chairman of the Defence Council, who received it on 19 May 1933 by the decision of the State Council. Baron Gustaf Mannerheim (1867–1951) served as Regent (1918–1919) and President of the Republic (1944–1946).
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.
Gorget patches are an insignia in the form of paired patches of cloth or metal on the collar of a uniform (gorget), used in the military and civil service in some countries. Collar tabs sign the military rank, the rank of civil service, the military unit, the office (department) or the branch of the armed forces and the arm of service.
Field marshal (FM) has been the highest rank in the British Army since 1736. A five-star rank with NATO code OF-10, it is equivalent to an Admiral of the Fleet in the Royal Navy or a Marshal of the Royal Air Force in the Royal Air Force (RAF). A Field Marshal's insignia consists of two crossed batons surrounded by yellow leaves below the Tudor Crown. Like Marshals of the Royal Air Force and Admirals of the Fleet, Field Marshals traditionally remain officers for life, though on half-pay when not in an appointment or retired. The rank has been used sporadically throughout its history, and was vacant during parts of the 18th and 19th centuries. After the Second World War, it became standard practice to appoint the Chief of the Imperial General Staff to the rank on his last day in the post. Army officers occupying the post of Chief of the Defence Staff, the professional head of all the British Armed Forces, were usually promoted to the rank upon their appointment.
Lieutenant field marshal, also frequently historically field marshal lieutenant, was a senior army rank in certain European armies of the 17th to 20th centuries. It emerged as the rank of field marshal came to be used for the highest army commander in the 17th century. In German-speaking countries the commander-in-chief usually appointed an "under marshal" or "lieutenant field marshal" to support and represent the field marshal. Amongst his functions as the personal deputy to the field marshal, were the supervision of supply depots and routes, and inspection of the guards.
Colonel general is a military rank used in some armies. The rank originates from the Old European System and it is particularly associated with Germany, where historically general officer ranks were one grade lower than in the Commonwealth and the United States, and Generaloberst was a rank above full General, but below Generalfeldmarschall. The rank of colonel general also exists in the armed forces organized along the lines of the Soviet model, where it is comparable to that of a lieutenant general.
A general of the branch, general of the branch of service or general of the ... is a three or four-star general officer rank in some armies. Several nations divide — or used to divide — their senior general officer ranks by the branch of troops they are qualified to command, or simply as an honorific title.
The ranks and rank insignia of the Red Army and Red Navy between 1940 and 1943 were characterised by continuing reforms to the Soviet armed forces in the period immediately before Operation Barbarossa and the war of national survival following it. The Soviet suspicion of rank and rank badges as a bourgeois institution remained, but the increasing experience of Soviet forces, and the massive increase in manpower all played their part, including the creation of a number of new general officer ranks and the reintroduction of permanent enlisted ranks and ratings.
