Squad X Core Technologies

In military terminology, a squad is among the smallest of military organizations and is led by a non-commissioned officer. NATO and US doctrine define a squad as an organization "larger than a team, but smaller than a section." while US Army doctrine further defines a squad as a "small military unit typically containing two or more fire teams." In US usage, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams.

Historically, a "squad" in the US Army was a sub-unit of a section, consisting of from as few as two soldiers to as many as 12 and was originally used primarily for drill and administrative purposes (e.g., billeting, messing, working parties, etc.). The smallest tactical sub-unit being the section, which was also known as a half-platoon (the platoon itself being a half company).

Depending upon the time period, the squad "leader" (not an official position title until 1891) could be a sergeant (the sergeant, in sections with only one corporal, led the section's first squad, while the lone corporal served as assistant section leader and led the section's second squad), a corporal (in sections with two corporals), a lance corporal (a rank the Army had in varying numbers and conditions from at least 1821 until 1920), a private first class (PFC) (the rank existing since 1846 but not earning its one chevron – taken from the abolished lance corporal rank – until 1920). or even a "senior" private (there being many long-service, or "professional," privates until the post-WWII era).

In 1891, the US Army officially defined a rifle "squad" as consisting of "seven privates and one corporal." The US Army employed the eight-man rifle squad through WWI and until the late 1930s under the Square Division organizational plan, in which sergeants continued to lead sections consisting of two squads.

Under the Triangular Division organization plan in 1939 rifle squads were no longer organized into sections. Instead, the squads were reorganized into a 12-man unit of three elements, or teams, Able, Baker, and Charlie, reporting directly to the platoon commander (an officer, usually a second lieutenant), assisted by a sergeant assigned as the "assistant to platoon commander" (re-designated as "platoon leader" in 1940 and as "platoon sergeant" in 1943 with the officer then re-designated as "platoon leader".) The squad leader was still only a corporal but the squad was also assigned a PFC (one of the scout riflemen) as the assistant to the squad leader. This soldier could serve as either the squad leader's messenger to the platoon commander or could be used to relay orders to other squad elements, as needed. While not a noncommissioned officer (NCO) the PFC was an experienced soldier, as prior to WWII the majority of enlisted men remained privates for the entire term of their enlistment since promotion opportunity was scarce. However, the obvious command (viz., leadership and supervision) weakness of so large a squad under one NCO rapidly became obvious in light of the pre-war mobilization and was corrected in 1940 when a second NCO was added to the squad.

This adjustment raised the squad leader to a sergeant (grade 4) and the assistant squad leader to a corporal (grade 5). The "platoon leader" (with the officer still being the "platoon commander") now became a staff sergeant, (grade 3). (In 1920 the enlisted rank structure was simplified and seven grades were established ranging from master sergeant as grade 1 to private as grade 7; staff sergeant being one of the new rank titles then established by combining several intermediate sergeant grades ranking above section leaders but below the company first sergeant.) This squad organization included two men serving as “scout (rifleman),” who along with the squad leader, formed the security element (i.e., reconnaissance and overwatch actions), designated as “Able.” The second element was a three-man Browning Automatic Rifle (BAR) team consisting of an automatic rifleman, an assistant automatic rifleman and an ammunition bearer. This element formed the “ base of fire” (viz., fire support in providing suppressive fires in the attack and protective fires in the defense) and was designated as “Baker.” Lastly, there were five riflemen and the assistant squad leader, who formed the “maneuver element” (e.g., flanking and assault movements in the attack and repelling and reinforcing actions in the defense), designated as “Charlie.”

In 1942, the Army had a massive restructuring of its Tables of Organization & Equipment (TO&Es) and increased the rank of the squad leader and assistant squad leader to staff sergeant and sergeant, respectively. (Platoon leaders now became technical sergeants, as grade 2, and first sergeants became equal in pay grade to master sergeants as grade 1.) The BAR man (automatic rifleman) and the senior rifleman of the Charlie element became corporals (grade 5) and de facto team leaders, even though not officially designated as such. (In 1943 NCO platoon leaders were re-designated as platoon sergeants and officer platoon commanders became platoon leaders.)

After WWII, in 1948, the Army decided to "downsize” the rifle squad to a nine-man organization (as well as realign its enlisted grade structure), as post-war analysis had shown that the 12-man squad was too large and unwieldy in combat. The squad leader was again called a sergeant (but retained the grade 3 pay grade and insignia of the rank of a staff sergeant, which was then eliminated.) The two scouts of the Able element were eliminated with the idea that all of the riflemen should be able to perform the scouting duties and would therefore all share in the associated inherent risk of that position. The Baker element's ammunition bearer was also eliminated, leaving the two-man BAR team as the base of fire, supervised by the assistant squad leader (again called a corporal), but remaining as a grade 4, since the rank of sergeant (three chevrons) was then eliminated. (PFC became grade 5, private was grade 6, and recruit was grade 7; PFCs wore one chevron and privates and recruits both wore none.) The five riflemen of the “Charlie” team, now led by the squad leader, remained as the maneuver element.

Also, in 1948, the rank title of the platoon sergeant changed from technical sergeant (which was eliminated) to sergeant first class (SFC) (grade 2) and the rank title of first sergeant was again eliminated, being retained only as an occupational title for the senior NCO of a company. In 1951 the pay grades were reversed, with master sergeant becoming E-7 (vice the previous grade 1) and sergeant first class becoming E-6, so that the squad leader became a sergeant (E-5) and the assistant squad leader, a corporal (E-4). (With PFC, PVT, and RCT being E-3, E-2, and E-1, respectively.)

In the 1956 the Army began reorganizing into its "Pentomic” plan under the ROCID (Reorganization of Current Infantry Divisions) TO&Es. The rifle squad was reorganized into an eleven-man organization with a sergeant (E-5) as squad leader and two five-man fire teams. Each fire team consisted of a corporal (E-4) team leader, an automatic rifleman, an assistant automatic rifleman, a grenad
