A battalion is a military unit. The use of the term "battalion" varies by branch of service. A battalion consists of 300 to 800 soldiers and is divided into a number of companies. A battalion is commanded by a lieutenant colonel. In some countries, the word "battalion" is associated with the infantry; the term was first used in Italian as battaglione no than the 16th century. It derived from the Italian word for battaglia; the first use of battalion in English was in the 1580s, the first use to mean "part of a regiment" is from 1708. A battalion is the smallest military unit capable of "limited independent operations", meaning it includes an executive, staff with a support and services unit; the battalion must have a source of re-supply to enable it to sustain operations for more than a few days. This is because a battalion's complement of ammunition, expendable weapons, rations, lubricants, replacement parts and medical supplies consists of only what the battalion's soldiers and the battalion's vehicles can carry.
In addition to sufficient personnel and equipment to conduct operations, as well as a limited administrative and logistics capability, the commander's staff coordinates and plans operations. A battalion's subordinate companies and their platoons are dependent upon the battalion headquarters for command, control and intelligence, the battalion's service and support structure; the battalion is part of a brigade, or group, depending on the branch of service. A battalion's companies are of one type, although there are exceptions such as combined arms battalions in the U. S. Army. A battalion includes a headquarters company and some sort of combat service support, combined in a combat support company; the term battalion is used in the British Army Infantry and some corps including the Royal Electrical and Mechanical Engineers, intelligence corps. It was used in the Royal Engineers, was used in the now defunct Royal Army Ordnance Corps and Royal Pioneer Corps. Other corps use the term "regiment" instead.
An infantry battalion is numbered ordinarily within its regiment. It has a headquarters company, support company, three rifle companies; each company is commanded by a major, the officer commanding, with a captain or senior lieutenant as second-in-command. The HQ company contains signals, catering, administration, training and medical elements; the support company contains anti-tank, machine gun, mortar and reconnaissance platoons. Mechanised units have an attached light aid detachment of the Royal Electrical and Mechanical Engineers to perform field repairs on vehicles and equipment. A British battalion in theatre during World War II had around 845 men, whereas, as of 2012, a British battalion had around 650 soldiers. With successive rounds of cutbacks after the war, many infantry regiments were reduced to a single battalion. Important figures in a battalion headquarters include: Commanding officer Second-in-command Adjutant Quartermaster Quartermaster Medical officer Administrative officer Padre Operations officer Regimental sergeant major Regimental quartermaster sergeant Regimental quartermaster sergeant Battalions of other corps are given separate cardinal numbers within their corps.
A battle group consists of an infantry battalion or armoured regiment with sub-units detached from other military units acting under the command of the battalion commander. In the Canadian Forces, most battalions are reserve units of between 100–200 soldiers that include an operationally ready, field-deployable component of a half-company apiece; the nine regular force infantry battalions each contain three or four rifle companies and one or two support companies. Canadian battalions are commanded by lieutenant-colonels, though smaller reserve battalions may be commanded by majors; those regiments consisting of more than one battalion are: The Royal Canadian Regiment Princess Patricia's Canadian Light Infantry Royal 22e Régiment The Royal Newfoundland Regiment Tactically, the Canadian battalion forms the core of the infantry battle group, which includes various supporting elements such as armour, combat engineers and combat service support. An infantry battle group will be commanded by the commander of the core infantry battalion around which it is formed and can range in size from 300 to 1,500 or more soldiers, depending on the nature of the mission assigned.
In the Royal Netherlands Army, a mechanised infantry battalion consists of one command- and medical company, three mechanised infantry companies, one support company
Admiral is one of the highest ranks in some navies, in many navies is the highest rank. It is abbreviated to "Adm" or "ADM"; the rank is thought to have originated in Sicily from a conflation of Arabic: أمير البحر, amīr al-baḥr, "commander of the sea", with Latin admirabilis or admiratus, although alternative etymologies derive the word directly from Latin, or from the Turkish military and naval rank miralay. The French version – amiral without the additional d – tends to add evidence for the Arab origin. In the Commonwealth and the U. S. a "full" admiral is equivalent to a "full" general in the army, is above vice admiral and below admiral of the fleet. In NATO, admirals have a rank code of OF-9 as a four-star rank; the word admiral in Middle English comes from Anglo-French amiral, "commander", from Medieval Latin admiralis, admirallus. These themselves come from Arabic amīr, or amīr al-, "commander of", as in amīr al-baḥr, "commander of the sea"; the term was in use for the Greco-Arab naval leaders of Norman Sicily, ruled by Arabs, at least by the early 11th century.
The Norman Roger II of Sicily, employed a Greek Christian known as George of Antioch, who had served as a naval commander for several North African Muslim rulers. Roger styled George in Abbasid fashion as Amir of Amirs, i.e. "Commander of Commanders", with the title becoming Latinized in the 13th century as ammiratus ammiratorum. The Sicilians and Genoese took the first two parts of the term and used them as one word, from their Aragon opponents; the French and Spanish gave their sea commanders similar titles while in Portuguese the word changed to almirante. As the word was used by people speaking Latin or Latin-based languages it gained the "d" and endured a series of different endings and spellings leading to the English spelling admyrall in the 14th century and to admiral by the 16th century; the word "admiral" has today come to be exclusively associated with the highest naval rank in most of the world's navies, equivalent to the army rank of general. However, this wasn't always the case.
The rank of admiral has been subdivided into various grades, several of which are extinct while others remain in use in most present day navies. The Royal Navy used colours to indicate seniority of its admirals until 1864; the generic term for these naval equivalents of army generals is flag officer. Some navies have used army-type titles for them, such as the Cromwellian "general at sea"; the rank insignia for an admiral involves four stars or similar devices and/or 3 stripes over a broad stripe, but as one can see below, there are many cases where the insignia do not involve four stars or similar devices. Admiral is a German Navy OF-9 four-star flag officer rank, equivalent to the German Army and German Air Force rank of General. Post-WWII rank is Bakurocho taru kaishō or Admiral serve as Chief of Staff, Joint Staff（幕僚長たる海将） with limited function as an advisory staff to Minister of Defense, compared to Gensui during 1872–1873 and 1898–1945. Admiral of Castile was a post with a important history in Spain.

Officer (armed forces)
An officer is a member of an armed forces or uniformed service who holds a position of authority. In its broadest sense, the term "officer" refers to commissioned officers, non-commissioned officers, warrant officers. However, when used without further detail, the term always refers to only commissioned officers, the more senior portion of a force who derive their authority from a commission from the head of state; the proportion of officers varies greatly. Commissioned officers make up between an eighth and a fifth of modern armed forces personnel. In 2013, officers were the senior 17% of the British armed forces, the senior 13.7% of the French armed forces. In 2012, officers made up about 18% of the German armed forces, about 17.2% of the United States armed forces. However, armed forces have had much lower proportions of officers. During the First World War, fewer than 5% of British soldiers were officers. In the early twentieth century, the Spanish army had the highest proportion of officers of any European army, at 12.5%, at that time considered unreasonably high by many Spanish and foreign observers.
Within a nation's armed forces, armies tend to have a lower proportion of officers, but a higher total number of officers, while navies and air forces have higher proportions of officers since military aircraft are flown by officers. For example, 13.9% of British army personnel and 22.2% of the RAF personnel were officers in 2013, but the army had a larger total number of officers. Having a command authority is one requirement for combatant status under the laws of war, though this authority need not have obtained an official commission or warrant. In such case, those persons holding offices of responsibility within the organization are deemed to be the officers, the presence of these officers connotes a level of organization sufficient to designate a group as being combatant. Commissioned officers receive training as leadership and management generalists, in addition to training relating to their specific military occupational specialty or function in the military. Many advanced militaries require university degrees as a prerequisite for commissioning from the enlisted ranks.
Others, including the Australian Defence Force, the British Armed Forces, Nepal Army, the Pakistani Armed Forces, the Swiss Armed Forces, the Singapore Armed Forces, the Israel Defense Forces, the Swedish Armed Forces, the New Zealand Defence Force, are different in not requiring a university degree for commissioning—although a significant number of officers in these countries are graduates. In the Israel Defense Forces, a university degree is a requirement for an officer to advance to the rank of lieutenant colonel; the IDF sponsors the studies for its majors, while aircrew and naval officers obtain academic degrees as a part of their training programmes. In the United Kingdom, there are three routes of entry for British Armed Forces officers; the first, primary route are those who receive their commission directly into the officer grades following completion at their relevant military academy. In the second method, an individual may gain their commission after first enlisting and serving in the junior ranks, reaching one of the senior non-commissioned officer ranks, as what are known as'direct entry' or DE officers.
The third route is similar to the second. LE officers, whilst holding the same Queen's commission work in different roles from the DE officers. In the infantry, a number of warrant officer class 1s are commissioned as LE officers. In the British Army, commissioning for DE officers occurs after a 44-week course at the Royal Military Academy Sandhurst for regular officers or the Army Reserve Commissioning Course, which consists of four two-week modules for Army Reserve officers; the first two modules may be undertaken over a year for each module at an Officers' Training Corps, the last two must be undertaken at Sandhurst. For Royal Navy and Royal Air Force officer candidates, a 30-week period at Britannia Royal Naval College or a 24-week period at RAF College Cranwell, respectively. Royal Marines officers receive their training in the Command Wing of the Commando Training Centre Royal Marines during a gruelling 15-month course; the courses consist of not only tactical and combat training, but leadership, management and international affairs training.
Until the Cardwell Reforms of 1871, commissions in the British Army were purchased by officers. The Royal Navy, operated on a more meritocratic, or at least mobile, basis. Commissioned officers are the only persons, in an armed forces environment, able to act as the commanding officer of a military unit. A superior officer is an officer with a higher rank than another officer, a subordinate officer relative to the superior. Non-commissioned officers, to include naval and coast guard petty officers and chief petty officers, in positions of authority can be said to have control or charge rather than command per se. Most officers in the Armed Forces of the United States are commissioned through one of three major commissioning programs: United States Military Academy Unit
A brigade is a major tactical military formation, composed of three to six battalions plus supporting elements. It is equivalent to an enlarged or reinforced regiment. Two or more brigades may constitute a division. Brigades formed into divisions are infantry or armored. In addition to combat units, they may include combat support units or sub-units, such as artillery and engineers, logistic units or sub-units; such brigades have sometimes been called brigade-groups. On operations, a brigade may comprise both organic elements and attached elements, including some temporarily attached for a specific task. Brigades may be specialized and comprise battalions of a single branch, for example cavalry, armored, air defence, engineers, signals or logistic; some brigades are classified as independent or separate and operate independently from the traditional division structure. The typical NATO standard brigade consists of 3,200 to 5,500 troops. However, in Switzerland and Austria, the numbers could go as high as 11,000 troops.
The Soviet Union, its forerunners and successors use "regiment" instead of brigade, this was common in much of Europe until after World War II. A brigade's commander is a major general, brigadier general, brigadier or colonel. In some armies, the commander is rated as a General Officer; the brigade commander has staff. The principal staff officer a lieutenant colonel or colonel, may be designated chief of staff, although until the late 20th century British and similar armies called the position'brigade-major'; some brigades may have a deputy commander. The headquarters has a nucleus of staff officers and support that can vary in size depending on the type of brigade. On operations, additional specialist elements may be attached; the headquarters will have its own communications unit. In some gendarmerie forces, brigades are the basic-level organizational unit. "The brigade as a military unit came about starting in the 15th century when the British army and militia developed a unit to control more than one infantry regiment or cavalry squadron".
Each regiment, cavalry squadron, or artillery battery operated somewhat independently, with its own field officer or battery commander reporting directly to the field force or "army" commander. As such a "field army" became larger, the number of subordinate commanders became unmanageable for the officer in general command of said army a major general, to command. In order to streamline command relationships, as well as effect some modicum of tactical control in regard to combined arms operations, an intermediate level of command became evident. "The term's origin is found in two French roots, which together, meant roughly'those who fight' ". Another theory for derivation of the term brigade derives from Italian brigata, as used for example in the introduction to The Decameron, where it refers only to a group of ten, or Old French brigare, meaning "company" of an undefined size, which in turn derives from a Celtic root briga, which means "strife"; the so-called "brigada" was a well-mixed unit, comprising infantry and also artillery, designated for a special task.
The size of such "brigada" ranged from a reinforced "company" of up to two regiments. The "brigada" was the forerunner of the modern "battalion task force", "battle group", or "brigade"; the brigade was improved as a tactical unit by the Swedish king Gustavus Adolphus, who introduced it in 1631 during a reorganization of the Swedish Army during the Thirty Years' War. The creation of the brigade overcame the lack of coordination inherent in the traditional army structure consisting of independent regiments of infantry and units of supporting arms acting separately under their individual commanding officers. Gustavus accomplished this battlefield coordination by combining battalions of infantry with cavalry troops and artillery batteries into a "battle group", viz. brigada or "brigade" commanded by a senior colonel, or lieutenant colonel, appointed as a brigadier-general. The brigade organization was copied in France by Maréchal Turenne, who made it a permanent standing unit, requiring the creation in 1667 of a permanent rank of brigadier des armées du roi.
Unlike the Swedish brigades, French brigades at that time were composed of two to five regiments of the same branch. The rank, intermediate between colonel and maréchal de camp, disappeared in 1788 and should not be confused with that of général de brigade, equivalent to a brigadier general. In the Argentinian Army, the typical brigade is composed of an HQ company, two or three battalions of the brigade´s main branch, which give the brigade its denomination, plus one battalion of the other branch, plus one or two artillery groups, an engineers battalion or company, a signals company, intelligence company, an army aviation section and a logistics battalion. Mountain brigades have a special forces company; the brigade is commanded by a brigadier general or a senior colonel, who may be promoted to general during his tenure as brigade comman
A platoon is a military unit composed of two or more squads/sections/patrols. Platoon organization varies depending on the country and the branch, but per the official tables of organization as published in U. S. military documents. S. infantry rifle platoon consists of 43 Marines. There are other types of infantry platoons, depending upon service and type of infantry company/battalion to which the platoon is assigned, these platoons may range from as few as 18 to 69. Non-infantry platoons may range from as small as a nine-man communications platoon to a 102-man maintenance platoon. A platoon leader or commander is the officer in command of a platoon; this person is a junior officer—a second or first lieutenant or an equivalent rank. The officer is assisted by a platoon sergeant. A platoon is the smallest military unit led by a commissioned officer. Rifle platoons consist of a small platoon headquarters and three or four sections or squads. In some armies, platoon is used throughout the branches of the army.
In a few armies, such as the French Army, a platoon is a cavalry unit, the infantry use "section" as the equivalent unit. A unit consisting of several platoons is called a company/battery/troop. According to Merriam-Webster, "The term was first used in the 17th century to refer to a small body of musketeers who fired together in a volley alternately with another platoon." The word came from pelote meaning a small ball. The suffix "-on" can be an augmentative suffix in French, but on the other hand is a diminutive suffix in relationship to animals, so the original intention in forming peloton from pelote is not clear. Nonetheless it is documented that it took the meaning of a group of soldiers firing a volley together, while a different platoon reloaded; this implies an augmentative intention in the etymology. Since soldiers were organized in two or three lines, which were supposed to fire volleys together, this would have meant platoons organised with the intention of a half or a third of the company firing at once.
The modern French word peloton, when not meaning platoon, can refer to the main body of riders in a bicycle race. Pelote itself comes from the low Latin "pilotta" from Latin "pila", meaning "ball", the French suffix "-on" derives from the Latin suffix "-onus"; the platoon was a firing unit rather than an organization. The system was said to have been invented by Gustavus Adolphus of Sweden in 1618. In the French Army in the 1670s, a battalion was divided into 18 platoons who were grouped into three "firings"; the system was used in the British, Austrian and Dutch armies. On 1 October 1913, under a scheme by General Sir Ivor Maxse, the regular battalions of the British Army were reorganised from the previous eight companies to a four company structure, with each company having four platoons as separate units each commanded by a lieutenant with a platoon sergeant as his deputy; each platoon was divided into four sections, each commanded by a corporal. Due to a shortage of officers, a non commissioned officer rank of Platoon Sergeant Major was introduced from 1938 to 1940 for experienced non-commissioned officers who were given command of platoons.
In the Australian Army, an infantry platoon has thirty-six soldiers organized into three eight-man sections and a twelve-man maneuver support section. A lieutenant as platoon commander and a sergeant as platoon sergeant, accompanied by a platoon signaller and sometimes a platoon medic. A section comprises eight soldiers led by a corporal with a lance corporal as second in command; each section has two fireteams of four men, one led by the corporal and the other by the lance corporal. Each fireteam has one soldier with a 7.62mm Maximi GSMG and the other three armed with F88 Steyr assault rifles. One rifle per fireteam has an attached 40mm grenade launcher. Fireteam bravo has a HK417 7.62mm for the designated marksman role. More the designated marksman of each Australian fireteam has been issued the HK417 in Afghanistan and afterwards; the platoon may have three MAG 58 general-purpose machine guns, one M2 Browning heavy machine gun or a Mk 19 grenade launcher at its disposal. In the British Army, a rifle platoon from an infantry company consists of three sections of eight men, plus a signaller, a platoon sergeant, the platoon commander and a mortar man operating a light mortar.
This may not be the case for all British Infantry units, since the 51mm mortars are not part of the TOE post-Afghanistan. Under Army 2020, a platoon in the Heavy Protected Mobility Regiments will consist of around 30 soldiers in four Mastiff/FRES UV vehicles; as of March 2016, the British Army is reviewing whether to retain the FN Herstal Para Minimi 5.56×45mm light machine gun and the M6-640 Commando 60 mm mortar at platoon level in dismounted units. Each section is commanded by a corporal, with a lance corporal as second-in-command and s
A regiment is a military unit. Their role and size varies markedly, depending on the arm of service. In Medieval Europe, the term "regiment" denoted any large body of front-line soldiers, recruited or conscripted in one geographical area, by a leader, also the feudal lord of the soldiers. By the end of the 17th century, regiments in most European armies were permanent units, numbering about 1,000 men and under the command of a colonel. During the modern era, the word "regiment" – much like "corps" – may have two somewhat divergent meanings, which refer to two distinct roles: a front-line military formation. In many armies, the first role has been assumed by independent battalions, task forces and other, similarly-sized operational units. However, these non-regimental units tend to be short-lived. A regiment may be a variety of sizes: smaller than a standard battalion, e.g. Household Cavalry Mounted Regiment. S. Infantry Regiment and Royal Regiment of Scotland; the French term régiment is considered to have entered military usage in Europe at the end of the 16th century, when armies evolved from collections of retinues who followed knights, to formally organised, permanent military forces.
At that time, regiments were named after their commanding colonels, disbanded at the end of the campaign or war. It was customary to name the regiment by its precedence in the line of battle, to recruit from specific places, called cantons; the oldest regiments which still exist, their dates of establishment, include the Spanish 9th Infantry Regiment “Soria”, Swedish Life Guards, the British Honourable Artillery Company and the King's Own Immemorial Regiment of Spain, first established in 1248 during the conquest of Seville by King Ferdinand the Saint. In the 17th century, brigades were formed as units combining infantry and artillery that were more effective than the older, single-arms regiments. By the beginning of the 18th century, regiments in most European continental armies had evolved into permanent units with distinctive titles and uniforms, each under the command of a colonel; when at full strength, an infantry regiment comprised two field battalions of about 800 men each or 8–10 companies.
In some armies, an independent regiment with fewer companies was labelled a demi-regiment. A cavalry regiment numbered 600 to 900 troopers. On campaign, these numbers were soon reduced by casualties and detachments and it was sometimes necessary to amalgamate regiments or to withdraw them to a depot while recruits were obtained and trained. With the widespread adoption of conscription in European armies during the nineteenth century, the regimental system underwent modification. Prior to World War I, an infantry regiment in the French, German and other smaller armies would comprise four battalions, each with a full strength on mobilization of about 1,000 men; as far as possible, the separate battalions would be garrisoned in the same military district, so that the regiment could be mobilized and campaign as a 4,000 strong linked group of sub-units. A cavalry regiment by contrast made up a single entity of up to 1,000 troopers. A notable exception to this practice was the British line infantry system where the two regular battalions constituting a regiment alternated between "home" and "foreign" service and came together as a single unit.
In the regimental system, each regiment is responsible for recruiting and administration. The regiment is responsible for recruiting and administering all of a soldier's military career. Depending upon the country, regiments can be administrative units or both; this is contrasted to the "continental system" adopted by many armies. In the continental system, the division is the functional army unit, its commander is the administrator of every aspect of the formation: his staff train and administer the soldiers and commanders of the division's subordinate units. Divisions are garrisoned together and share the same installations: thus, in divisional administration, a battalion commanding officer is just another officer in a chain of command. Soldiers and officers are transferred out of divisions as required; some regiments recruited from specific geographical areas, incorporated the place name into the regimental name. In other cases, regiments would recruit from a given age group within a nation, an ethnic group, or foreigners.
In other cases, new regiments were raised for new functions within an army.
In military organizations, an artillery battery is a unit of artillery, rocket artillery, multiple rocket launchers, surface to surface missiles, ballistic missiles, cruise missiles etc. so grouped to facilitate better battlefield communication and command and control, as well as to provide dispersion for its constituent gunnery crews and their systems. The term is used in a naval context to describe groups of guns on warships. Artillery battery origins from a Grand Duchy of Lithuania bajoras and artillery expert Kazimieras Simonavičius' book Artis Magnae Artilleriae published in 1650, which contains a large chapter on caliber, construction and properties of rockets, including multistage rockets, batteries of rockets, rockets with delta wing stabilizers; the term "battery" referred to a cluster of cannon in action as a group, either in a temporary field position during a battle or at the siege of a fortress or a city. Such batteries could be a mixture of howitzer, or mortar types. A siege could involve many batteries at different sites around the besieged place.
The term came to be used for a group of cannon in a fixed fortification, for coastal or frontier defence. During the 18th century "battery" began to be used as an organizational term for a permanent unit of artillery in peace and war, although horse artillery sometimes used "troop" and fixed position artillery "company", they were organised with between six and 12 ordnance pieces including cannon and howitzers. By the late 19th century "battery" had become standard replacing company or troop. In the 20th century the term was used for the company level sub-unit of an artillery branch including field, air-defence, anti-tank and position. Artillery operated target acquisition emerged during the First World War and were grouped into batteries and have subsequently expanded to include the complete intelligence, target acquisition and reconnaissance spectrum. 20th-century firing batteries have been equipped with mortars, howitzers and missiles. During the Napoleonic Wars some armies started grouping their batteries into larger administrative and field units.
Groups of batteries combined for field combat employment called Grand Batteries by Napoleon. Administratively batteries were grouped in battalions, regiments or squadrons and these developed into tactical organisations; these were further grouped into regiments "group" or brigades, that may be wholly composed of artillery units or combined arms in composition. To further concentrate fire of individual batteries, from World War I they were grouped into "artillery divisions" in a few armies. Coastal artillery sometimes had different organizational terms based on shore defence sector areas. Batteries have sub-divisions, which vary across armies and periods but translate into the English "platoon" or "troop" with individual ordnance systems called a "section" or "sub-section", where a section comprises two artillery pieces; the rank of a battery commander has varied, but is a lieutenant, captain, or major. The number of guns, mortars or launchers in an organizational battery has varied, with the calibre of guns being an important consideration.
In the 19th century four to 12 guns was usual as the optimum number to maneuver into the gun line. By the late 19th century the mountain artillery battery was divided into a gun line and an ammunition line; the gun line consisted of 12 ammunition mules. During the American Civil War, artillery batteries consisted of six field pieces for the Union Army and four for the Confederate States Army, although this varied. Batteries were divided into sections of two guns apiece, each section under the command of a lieutenant; the full battery was commanded by a captain. As the war progressed, individual batteries were grouped into battalions under a major or colonel of artillery. In the 20th century it varied between four and 12 for field artillery, or two pieces for heavy pieces. Other types of artillery such as anti-tank or anti-aircraft have sometimes been larger; some batteries have been "dual-equipped" with two different types of gun or mortar, taking whichever was more appropriate when they deployed for operations.
From the late 19th century field artillery batteries started to become more complex organisations. First they needed the capability to carry adequate ammunition each gun could only carry about 40 rounds in its limber so additional wagons were added to the battery about two per gun; the introduction on indirect fire in the early 20th century necessitated two other groups, firstly observers who deployed some distance forward of the gun line, secondly a small staff on the gun position to undertake the calculations to convert the orders from the observers into data that could be set on the gun sights. This in turn led to the need for signalers, which further increased as the need to concentrate the fire of dispersed batteries emerged and the introduction fire control staff at artillery headquarters above the batteries. Fixed artillery refers to guns or howitzers on mounts that were either anchored in one spot, or on carriages intended to be moved only for the purposes of aiming, not for tactical repositioning.
Historical versions closely resembled naval cannon of their day, "garrison carriages," like naval carriages, were short and had four small wheels meant for rolling on
