Editing Company (military unit) (section)

====Historical background====
In the 1700s, British Army, [[Militia (United States)#History|American Colonial Militia]], and Provincial Regulars (e.g., the [[Virginia Regiment]]), and later American Army infantry, regiments were organized into companies of somewhat less than 100 officers and enlisted men, although the actual totals widely varied. For example, in 1775, a typical British Army infantry company contained only 47 personnel (comprising 3 officers, 5 noncommissioned officers, a drummer, and 38 privates). However, by 1792, an American infantry company contained 98 personnel (comprising 3 officers, 9 noncommissioned officers, a drummer, a fifer, and 84 privates).<!--You use 'including' when you list only some of the components-->

Beginning in 1775, American forces began to develop their own organizational doctrine somewhat based on the Franco-Prussian model (with much influence beginning in 1777 from Continental European expatriates and future American generals the [[Gilbert du Motier, Marquis de Lafayette#American Revolution|Marquis de Lafayette]] of France, [[Casimir Pulaski#In the United States|Count Casimir Pulaski]] of Poland, and [[Friedrich Wilhelm von Steuben#American Revolution|Baron von Steuben]] of Prussia). As a result, in 1776, a Continental Army Infantry company was authorized one captain, one first lieutenant, one second lieutenant (both lieutenants serving as platoon commanders – not designated as platoon ''leaders'' until 1943 under the "Triangular Division" reorganization begun in 1939), an ensign (an obsolete subaltern officer rank charged with carrying the regimental colors in rotation with the other ensigns of the battalion/regiment), four sergeants (section leaders/squad leaders with two to a platoon), four corporals (assistant section leaders/squad leaders with two to a platoon), two musicians (a drummer and a fifer), and 76 privates. The company was organized into two platoons, each consisting of two sections/squads (the terms were sometimes used interchangeably) consisting of one sergeant, one corporal, and 19 privates.

From the late 1700s up until the late 1800s, a US infantry company was commanded by a captain and assisted by a [[first sergeant]] (first authorized in 1781), and consisted of a small company headquarters and two identical platoons commanded by lieutenants. Even though from 1808 until 1821 companies were authorized two first lieutenants and two second lieutenants (and again from 1861 to 1866 for two second lieutenants), the positions of company executive officer (second-in-command) and a third platoon commander were not authorized until 1898 when the army expanded under mobilization for the war with Spain. During the 1800s the authorized strength of infantry companies fell to a low of 54 officers and men during periods of relative peace from 1821 to 1838 and again from 1842 to 1846. In contrast, from 1812 to 1815 (second war with Great Britain), 1846 to 1848 (war with Mexico), 1861 to 1890 (American civil war and wars with the plains Indians), and 1898–1899 (war with Spain) authorized company strength ranged from over 100 officers and men up to a high of 119. Also, in 1861 a company quartermaster sergeant was added to the authorized manning of an infantry company and a wagoner was reinstituted (previously authorized from 1796 to 1808) to drive the company supply wagon.

During the 1700s and up until the late 1800s, the company was an administrative and tactical unit seldom employed in other than as a massed formation. The standard procedure, once the company had marched into its position in the line of battle, was for the company to form facing the enemy as two ranks, by platoon, one behind the other. The commanding officer (a captain), and the one to four lieutenants (depending upon the time period) serving as platoon commanders/assistant platoon commanders (1808 to 1821) and the executive officer would direct the fighting, leading from the front in the attack and on the flanks in the defense. The executive officer, or more usually the junior lieutenant, and the first sergeant were normally positioned behind the battle line so as to assist the company commander in overseeing the company and managing the rear (company trains with the quartermaster sergeant and wagoner, casualties, enemy prisoners, non-combatants, deserters, etc.). The sergeants, acted as "file closers", working the line by putting men forward to replace casualties in the front rank, encouraging men to fire, reload, move forward, etc. and if need be, physically assisting or restraining men who refused to move forward or attempted to flee. The corporals physically led by example (much like modern fire team leaders) by taking their place in the line with their privates and fighting alongside them.

The ensign, the junior officer in the company from 1775 until 1808 and nominally the "color bearer", usually either personally carried the regimental battle flag or supervised the detailed party of NCOs and privates drawn from the companies tasked with bearing and protecting the flag. The rank and position of ensign (as well as cornet in mounted units) was eliminated in the early 1800s when incumbents were converted to second lieutenants. It had already become the custom to assign a veteran sergeant to carry the national colors as only regiments and separate battalions were authorized to carry a "battle flag". A special group of NCOs, led by the "color sergeant", chosen for their experience and fighting skills, were detailed from the companies to the regimental headquarters to carry and defend the national colors (the United States flag) and the regimental colors (the regiment's unique standard bearing its branch and regiment designation as well as its battle honors and unit decorations).

The musicians remained with the commanding officer to relay orders by sound (i.e., musical notes and drumbeats). Sometimes, the regimental commander would group the musicians as a regimental band positioned behind the left center company in the line of battle, with the drummers forming a regimental drum-line for use by the regimental commander in giving orders to the several companies by drumbeats. As needed, the musicians also served as orderlies and guards at either the company or battalion/regimental headquarters and in combat served as messengers, water carriers, stretcher bearers, and temporarily guarded enemy prisoners of war until they were passed to the rear for processing and internment.

In 1898, with the expansion of the rifle company to three platoons under mobilization for the [[Spanish–American War]], the company gained two officers (an additional first lieutenant as executive officer and an additional second lieutenant to command the third platoon). Additionally, there was an increase in the number of noncommissioned officers (NCOs) to serve as section leaders (sergeants) and squad leaders (corporals) to the point that in 1901 with the increase in privates to 127 (from 84 in 1898) that there were then authorized 18 corporals and six sergeants, along with two buglers (the bugle having replaced both the drum and the fife in infantry companies), the wagoner, two senior NCOs (first sergeant and quartermaster sergeant), and five officers for a total of 161 officers and men. In 1905, a mess sergeant was added to the company's senior NCO staff and the company quartermaster sergeant was renamed supply sergeant.

Due to mobilization for World War I, the army adopted its "square division" organization structure, significantly increasing unit sizes from platoon up. In 1917, a fourth platoon was added to the company, increasing its size to 256 officers and men, including six officers (a captain as commanding officer, a first lieutenant as executive officer, and two first lieutenants and two second lieutenants as platoon commanders). Enlisted strength became: three senior NCOs (first sergeant, supply sergeant, and mess sergeant), 12 sergeants, 33 corporals (one company clerk and 32 squad leaders with eight per platoon), eight specialists (four cooks and four mechanics), two buglers, 64 privates first class, and 128 privates. Of the 12 sergeants, while eight of them continued to serve as section leaders (with two in each platoon), the four senior ranking sergeants were assigned to a new position in each platoon headquarters as "assistant to platoon commander". This was the forerunner of the modern platoon sergeant slot created in 1943 (originally known in 1940 as the "platoon leader", as the officer was styled as the "platoon commander" until 1943) to provide an experienced senior NCO as an advisor and second-in-command to the officer commanding the platoon.

Cavalry companies (not officially re-designated as "troops" until 1883) had a similar organization to the infantry, but with fewer men, companies rarely exceeding around 70 men. In the Field Artillery, the company-equivalent unit is designated as a "battery" and historically consisted of a battery headquarters and two or three gun platoons, each with two gun sections. At full authorized strength, a typical battery of six gun sections would consist of approximately 100 officers and enlisted men.
