Another name for the half file was a hèmilochion with a hèmilochitès being a half-file leader.

Different types of units, however, were divided differently and therefore their leaders had different titles.

Origins of modern ranks
As the Middle Ages came to an end, the rank structure of medieval armies became more formalized. The top officers were known as commissioned officers because their rank came from a royal commission. Army commissions were reserved for the elite — the aristocracy of mainland Europe and the aristocracy and gentry of Great Britain.

The basic unit of the medieval army was the company

Not all officers received a commission from the King. Certain specialists were granted a warrant, certifying their expertise as craftsmen. These warrant officers assisted the commissioned officers but ranked above the noncommissioned officers. They received their authority from superior officers rather than the King. The highest rank of NCO was sergeant
Sergeant

Sergeant is a Military rank used in some form by most militaries, police forces, and other uniformed organizations around the world. Its origins are the Latin serviens, "one who serves", through the French term Sergent....
. The first sergeants were the armed servants (men-at-arms) of the aristocracy, assigned to command, organize and train the militia units raised for battle. After years of commanding a squad, a NCO could be promoted to sergeant. While a sergeant might have commanded a squad upon promotion, he usually became a staff officer. While commissioned staff officers assisted their commander with personnel, intelligence, operations and logistics, the sergeant was a jack of all trades, concerning himself with all aspects of administration to maintain the enlisted men serving under his commander. Over time, sergeants were differentiated into many ranks as various levels of sergeants were used by the commanders of various levels of units.

A corporal commanded a squad
Squad

In military terminology, a squad is a small military unit led by a non-commissioned officer that is subordinate to an infantry platoon. In countries following the British Army tradition this organization is referred to as a section ....
. Squad derived from the Italian word for a “square” or “block” of soldiers. In fact, corporal was derived from the Italian caporal de squadra (head of the squad). Corporals were assisted by lancepesades. Lancepesades were veteran soldiers; lancepesade was derived from the Italian lanzia spezzata meaning broken spear - the broken spear being a metaphor for combat experience, where such an occurrence was likely. The first lancepesades were simply experienced privates; who either assisted their corporal or performed the duties of a corporal themselves. It was this second function that made armies increasingly regard their lancepesades as a grade of corporal rather than a grade of private. As a result, the rank of Lance Corporal
Lance Corporal

Lance Corporal is a military rank, used by many armed forces worldwide, and also by some police forces and other uniformed organizations. It is below the rank of Corporal, and is typically the lowest Non-commissioned officer or enlisted rank, usually equivalent to the Ranks and insignia of NATO....

. The private was a man who signed a private contract with the company commander, offering his services in return for pay. The money was raised through taxation; those yeomen (smallholding peasants) who did not fulfill their annual 40-day militia service paid a tax that funded professional soldiers recruited from the yeomanry. This money was handed to the company commanders from the royal treasury, the company commanders using the money to recruit the troops.

Origins of higher ranks

As armies grew larger, composed of multiple companies, one captain was granted general (overall) authority over the field armies by the King. (National armies were the armies of the kings. Field armies were armies raised by the King to enter the battle field in preparation for major battles.) In French history, “lieutenant du roi” was a title borne by the officer sent with military powers to represent the king in certain provinces. A lieutenant du roi was sometimes known as a lieutenant general

As armies grew bigger, they were split ile heraldry and unit identification remained primarily a matter of the regiment. Brigades headed by brigadier generals were the units invented as a tactical unit, by the Swedish king Gustavus Adolphus. It was introduced to overcome the normal army structure, consisting of regiments. The so-called “brigada” was a mixed unit, comprising infantry, cavalry and normally artillery

 too, designated for a special task. The size of such “brigada” was a reinforced company up to two regiments. The “brigada” was a 17th century form of the modern “task force”.

Around the end of the 16th century, companies were grouped into regiments. The officers commissioned to lead these regiments were in fact called colonels (column officers). They were first appointed in Spain by King Ferdinand II of Aragon

From the mid-18th century until well into the 20th century, it was the most powerful navy in the world, playing a key part in establishing the British Empire as the dominant world power from 1815 until the early 1940s....

Size of command


Example of Unit Size and Nomenclature (U.S. Marine Corps)

To get a sense of the practical meaning of these ranks—and thus to be able to compare them across the different armed services, different nations, and the variations of titles and insignia—an understanding of the relative levels and sizes of each command will be helpful.

 ground forces can serve as a template for this purpose. It should be remembered that different countries will often use their own systems which won't match that of the U.S. Marines. In fact, the U.S. Army assigns a different rank to command the same type of unit as the Marines.

 and as many as seven others. So a Company can comprise from roughly 175 to 225 individuals. Equivalent units also commanded by Captains are Batteries and Detachments. In English speaking countries, a Company (or troop in the Cavalry or Armor, and Battery in the Artillery) is usually designated by a letter, e.g. A Company. In non-English speaking countries, they are usually numbered.

A regiment is a military unit, composed of variable numbers of battalions, commanded by a Colonel. Depending on the nation, military branch, mission, and organization, a modern regiment resembles a brigade, in that both range in size from a few hundred to 5,000 soldiers ....
 or Group, often consisting of four Battalions (for an Infantry unit) or five to six Air Groups (for a Wing). Battalions and Regiments are usually numbered, either as a separate Battalion or as part of a Regimental structure, e.g. 1/1 Marines in the Marine Corps or 1-501st Infantry in the US Army.

In these latter, abstractions cease to be helpful and it becomes necessary to turn to an actual unit. The 1st Battalion of the 1st Marine Regiment of the 1st Marine Division of the I Marine Expeditionary Force consists of three infantry companies, one weapons company, and one headquarters and service company. Above that, the 1st Marine Regiment (First Marines) consists of four such Battalions and one headquarters company. Marine Air Control Group 18

, a Brigade is roughly equal to or a little larger than a Regiment, consisting of three to seven battalions. Strength typically ranges from 1,500 to 3,500 personnel. In the U.S. Marines, Brigades are only formed for certain missions. In size and nature they are larger and more varied collections of Battalions than is common for a Regiment, fitting them for their traditional role as the smallest formation able to operate independently on a battlefield without external logistical tactical support. Brigades are usually numbered, e.g. 2nd Brigade.

The 1st Marine Division, for example, is made up of four Marine Regiments (of the type described above), one Assault Amphibian Battalion, one Reconnaissance Battalion, two Light Armored Reconnaissance Battalions, one Combat Engineer Battalion, one Tank Battalion, and one Headquarters Battalion—totalling more than 19,000 Marines.

 Company, one Communications Company, and one Truck Company.) An equivalent elsewhere within the same Marine Expeditionary Force (MEF) might be a MEF Logistics Group (MLG) - which is not a regimental-sized unit (as the word "group" implies), but rather a large support unit consisting of several battalions of support personnel. Divisions are normally numbered, but can be named after a function or personage.

Considering such a variety of units, the command sizes for any given rank will vary widely. Not all units are as troop intensive as infantry forces need to be. Tank

 commanded in theory by a General (four stars), but often by a Lieutenant General (three stars), and comprising as many as 240,000 troops. Armies are numbered by spelled-out numerals or functional titles, using their nationality in Combined forces, e.g. Eighth (US) Army, Third (ROK) Army, British Army of the Rhine (BAOR).

These were in their turn formed into Army Groups

These examples illustrate a standard that holds true all over the world and throughout history: rank generally implies size of command in a nested system of ranks and commands. The specific size of a command for any given rank will, however, depend on the task the unit performs, the nature of weapons used, and the strategies of warfare.
