fireteam

A fireteam is a small military subunit that forms part of a larger infantry squad. It is designed to provide controlled, mobile firepower and flexible maneuverability, allowing rapid, independent action within the broader unit. Fireteams are typically used to enable fire and movement, reconnaissance, and suppression of enemies while bassed on teamwork and communication with the squad.

A standard fireteam often consists of four members, though compositions vary by country and unit. Common roles include a team leader (often a corporal or sergeant), a rifleman, an automatic rifleman who provides sustained suppressive fire, and a grenadier who operates a launcher or a designated marksman. Some forces substitute or add a fourth role such as a second rifleman or a marksman, adapting to mission needs. Each member specializes in a weapon system and supports the others through mutual fire support and protection.

Tactics and employment centers on interdependence and coordinated movement. Fireteams maneuver together in formations that balance firepower and protection, using bounding overwatch, flanking, and suppression to gain and maintain contact with the enemy. Within a squad, multiple fireteams operate semi-independently under the direction of the squad leader, enabling rapid response to threats and terrain challenges.

History and usage: the fireteam concept became widespread in 20th-century infantry doctrine, evolving through World War II and the Cold War. Today it remains a common organizational unit in many Western militaries, though some forces structure their squads around different subunits or use alternative four- or three-man configurations. Overall, the fireteam represents a modular element designed for flexibility and effectiveness in close-quarters and field combat.
