A fireteam or fire team is a small military sub-subunit of infantry designed to optimise "bounding overwatch" and "fire and movement" tactical doctrine in combat. Depending on mission requirements, a typical fireteam consists of four or fewer members; an automatic rifleman, a grenadier (M203), a rifleman, and a designated team leader. The role of each fireteam leader is to ensure that the fireteam operates as a cohesive unit. Two or three fireteams are organised into a section or squad in co-ordinated operations, which is led by a squad leader.
Military theorists consider effective fireteams as essential for modern professional militaries as they serve as a primary group. Psychological studies by the United States Army have indicated that a soldier's survivability and the willingness to fight is more heavily influenced by the desire to both protect and avoid failing to support other members of the fireteam than by abstract concepts or ideologies. Historically, nations with effective fireteam organisation have had a significantly better performance from their infantry units in combat than those limited to operations by traditionally larger units.
Fireteams are the second smallest organized unit in the militaries that use it; the smallest being three or fewer soldier support or specialist teams (such as anti-tank teams, HMG teams, mortar teams, sniper teams, EOD teams, or military working dog teams) that are designed to operate independently.
Fireteams are the primary unit upon which modern infantry organisation is based in the British Army, Royal Air Force Regiment, Royal Marines, United States Army, United States Marine Corps, United States Air Force Security Forces, Canadian Forces, and Australian Army.
The concept of the fireteam is based on the need for tactical flexibility in infantry operations. A fireteam is capable of autonomous operations as part of a larger unit. Successful fireteam employment relies on quality small unit training for soldiers, experience of fireteam members operating together, sufficient communications infrastructure, and a quality non-commissioned officer corps to provide tactical leadership for the team.
These requirements have led to successful use of the fireteam concept by more professional militaries. It is less useful for armies employing massed infantry formations, or with significant conscription. Conscription makes fireteam development difficult, as team members are more effective as they build experience over time working together and building personal bonds.
In combat, while attacking or manoeuvring, a fireteam generally spreads over a distance of 50 metres (160 ft), while in defensive positions the team can cover up to the range of its weapons or the limits of visibility, whichever is less. In open terrain, up to 500 metres (1,600 ft) can be covered by an effective team, although detection range limits effectiveness beyond 100 metres (330 ft) or so without special equipment. A team is effective so long as its primary weapon remains operational.
In the Canadian Army 'fireteam' refers to two soldiers paired for fire and movement. Two fireteams form an 'assault group' which is analogous to most other militaries' understanding of a fireteam; two assault groups and a vehicle group of one driver and one gunner form a section of ten soldiers.
The French Section (Groupe de Combat - "Combat Group") is divided into two teams. The "Fire Team" (Equipe de feu) is based around the section-level automatic rifle or light machine gun. The "Shock Team" (Equipe de choc), made up of riflemen armed with rifle grenades or disposable rocket launchers, is the reconnaissance and maneuver unit. The teams employ bounding overwatch, with one element covering as the other moves. The team leaders have handheld radios so the elements can stay in contact with each other, as well as with the section leader's backpack radio set. The most common symbol of the modern French junior NCO (chef d'equipe) has been a radio hanging around their neck.
Infantry units of the British Army, Royal Marines and RAF Regiment introduced the fireteam concept following the adoption of the SA80 rifle and light support weapon. An infantry section of eight men contains two fireteams, Charlie and Delta, each comprising an NCO (Corporal or Lance Corporal) and three privates.
The fireteam is generally used as a subdivision of the section for fire and manoeuvre rather than as a separate unit in its own right, although fireteams or fireteam-sized units are often used for reconnaissance tasks, special operations, and urban patrols (usually being to referred to as a 'brick' in the latter scenario).
In a Stryker Brigade Combat Team (SBCT)'s infantry rifle companies, one man in each rifle squad fireteam is either the squad anti-armour specialist (RMAT) armed with the FGM-148 Javelin, or the squad designated marksman (DM) who carries the M4 carbine and M14 rifle. In both cases, these two positions replace the basic rifleman of the standard rifle squad.
The United States Marine Corps doctrine dictates that any active fireteam will include at least one 2-man gunnery-team and summarises its fireteam organisation with the mnemonic "ready-team-fire-assist", the following being the arrangement of the fireteam when in a column:
Navy Construction Force, "Seabee" Construction Battalions, utilise fireteams (as well as companies, platoons, and squads), similar in size to those employed by the USMC, in their organisational structure. Seabee units may be attached to Marine Corps units.
Many other armed forces see the squad as the smallest military unit; some countries' armies have a pair consisting of two soldiers as the smallest military unit. In others a fireteam is composed of two pairs of soldiers (fire and manoeuvre team) forming a fireteam. Chinese military forces traditionally use a three-man 'cell' (equivalent to fireteam) as the smallest military formation.
Fireteams have their origins in the early 20th century. From the Napoleonic Wars until World War I, military tactics involved central control of large numbers of soldiers in mass formation where small units were given little initiative.
Skirmishers in the Napoleonic War would often work in teams of two, ranging ahead of the main group and providing covering fire for each other. During World War I, trench warfare resulted in a stalemate on the Western Front. In order to combat this stalemate, the Germans developed a doctrinal innovation known as infiltration tactics (based on the Russian tactics used in the Brusilov Offensive), in which a brief intensive artillery preparation would be followed by small, autonomous teams of stormtroopers, who would covertly penetrate defensive lines. The Germans used their stormtroopers organised into squads at the lowest levels to provide a cohesive strike force in breaking through Allied lines. The British and Canadian troops on the Western Front started dividing platoons into sections after the Battle of the Somme in 1916. (This idea was later further developed in World War II). French Chasseur units in WWI were organised into fireteams, equipped with a light machine gun (Chauchat) team and grenades, to destroy German fire positions by fire (not assault) at up to 200 meters using rifle grenades. The light machine gun team would put suppressive fire on the enemy position, while the grenadier team moved to a position where the enemy embrasure could be attacked with grenades. The Chasseur tactics were proven during the Petain Offensive of 1917. Survivors of these French Chasseur units taught these tactics to American infantry, who used them with effectiveness at St. Mihiel and the Argonne. It was typical of a fireteam in this era to consist of four infantrymen: two assaulters with carbines, one grenadier, and one sapper.
In the inter-war years, United States Marine Corps Captain Evans F. Carlson went to China in 1937 and observed Communist 8th Route Army units of the National Revolutionary Army in action against the Imperial Japanese army. Carlson and Merritt A. Edson are believed to have developed the fireteam concept during the United States occupation of Nicaragua (1912-1933). At that time the US Marine squad consisted of a Corporal and seven Marines all armed with a bolt-action M1903 Springfield rifle and an automatic rifleman armed with a Browning Automatic Rifle. The introduction of the Thompson submachine gun and Winchester Model 1912 shotgun was popular with the Marines as a point-defense weapon for countering ambush by Nicaraguan guerrillas within the thick vegetation that could provide cover for a quick overrun of a patrol. A team of four men armed with these weapons had proven more effective in terms of firepower and manoeuvrability than the standard nine-man rifle squad.
Carlson later brought these ideas back to the US when the country entered World War II. Under his command, the 2nd Marine Raider battalion were issued with the semi-automatic M1 Garand rifle and were organised in the standard 4-man fireteam (although it was called firegroup) concept, 3 firegroups to a squad with a squad leader. A firegroup was composed of an M1 Garand rifleman, a BAR gunner and a submachine gunner. After sustaining severe wounds, Carlson was replaced and his battalion later disbanded and re-organised under conventional Marine doctrine of ten-man squads. Later, Carlson's fireteam concept was re-adopted.
WWII US Army rifle squads consisted of twelve soldiers divided into three teams. An Able "A" team (squad leader and two scouts), Baker "B" team (BAR gunner, assistant gunner, and ammunition bearer) and Charlie "C" team (assistant squad leader, also serving as the anti-tank grenadier, and five riflemen, one of whom served as the alternate anti-tank grenadier). In an assault the A team would provide overwatch and security or assist the C team in the assault, as the squad leader directed, while the B team provided suppressive fire. Suppressive fire from the BAR would be supplemented by fire from the rifles of his team as he reloaded, and could be further supplemented by platoon medium machine guns.
The US Army Rangers and Special Service Force adopted an early Fire Team concept when on campaign in Italy and France. Each Squad sub-unit of 4 to 5 men was heavily armed. Each Fire Team was composed of a 2-man BAR automatic rifleman and assistant, a scout (marksman/grenadier) armed with a M1903 Springfield with a rifle grenade discharger, and a team leader armed with an M1 carbine or M1 SMG. Their later misuse as conventional infantry negated their special training and fighting skill and their use as "fire brigades" against larger enemy forces negated their advantages in aggressiveness and firepower.
Meanwhile, the Communist Chinese established the three-man fireteam concept as the three-man cell when they organized a regular army, and its organization seemed to have been disseminated throughout all of Asia's communist forces, perhaps the most famous of which are the PAVN/NVA (People's Army of Vietnam/North Vietnamese Army) and the Viet Cong.
A battle pair is the smallest unit above the individual soldier, in the modern era chiefly employed by Baltic militaries. It consists of two soldiers with one soldier acting as senior of the two fighters (decided amongst the two or by their superior). A fireteam in turn consists of at least two fire and manoeuvre teams, and a squad of two or more fireteams.
Such a team is known as a Lahingpaar or battle pair.
Until 2015 in the Finnish Defence Forces, three taistelupari (combat pairs) formed a squad along with a squad leader. A three-man fireteam is now the smallest standard unit in the Finnish infantry doctrine.
The French Army has the concept of a Binome ("pair"). In the regular forces it is the pairing of an experienced soldier with a recruit or replacement. The new man learns from the experienced man how to properly perform the everyday tasks and responsibilities of his assignment.
In the old Colonial Forces (like the Legion Etrangere) it was a means of imposing order. The pair were responsible for each other - if one member broke the rules or deserted, the other would be punished for not preventing it.
According to the Swedish Armed Forces field manual, a Stridspar or trained fire and maneuver team is as effective as four individual soldiers of same quality. However, the efficiency of the fire and maneuver team has been challenged by many experts as it has been claimed to be insufficient in close-quarter situations where many fighting techniques have been designed for larger units.
