Infantry is a specialization of military personnel who engage in warfare combat. Infantry generally consists of light infantry, irregular infantry, heavy infantry, mountain infantry, motorized infantry, mechanized infantry, airborne infantry, air assault infantry, and naval infantry. Other types of infantry, such as line infantry and mounted infantry, were once commonplace but fell out of favor in the 1800s with the invention of more accurate and powerful weapons.
A battalion is a military unit, typically consisting of up to one thousand soldiers. Commanded by a lieutenant colonel and subdivided into several companies, each typically commanded by a major or a captain. The typical battalion is built from three operational companies, one weapons company and one headquarters company. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations.
A company is a military unit, typically consisting of 100–250 soldiers and usually commanded by a major or a captain. Most companies are made up of three to seven platoons, although the exact number may vary by country, unit type, and structure.
A platoon is a military unit typically composed of two to four squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 20–50 troops, although specific platoons may range from 10 to 100 people. A platoon is typically the smallest military unit led by a commissioned officer. The platoon leader is usually a junior officer—a second or first lieutenant or an equivalent rank. The officer is usually assisted by a platoon sergeant.
In military terminology, a squad is among the smallest of military organizations and is led by a non-commissioned officer. NATO and U.S. doctrine define a squad as an organization "larger than a team, but smaller than a section." while U.S. Army doctrine further defines a squad as a "small military unit typically containing two or more fire teams." In American usage, a squad consists of eight to fourteen soldiers, and may be further subdivided into fireteams.
A fireteam or fire team is a small modern military subordinated element of infantry designed to optimize "NCO initiative", "combined arms", "bounding overwatch" and "fire and movement" tactical doctrine in combat. Depending on mission requirements, a typical "standard" fireteam consists of four or fewer members: an automatic rifleman, a grenadier, a rifleman, and a designated fireteam leader. The role of each fireteam leader is to ensure that the fireteam operates as a cohesive unit. Two or three fireteams are organized into a section or squad in co-ordinated operations, which is led by a squad leader.
A combat engineer is a type of soldier who performs military engineering tasks in support of land forces combat operations. Combat engineers perform a variety of military engineering, tunnel and mine warfare tasks, as well as construction and demolition duties in and out of combat zones.
A section is a military sub-subunit. It usually consists of between 6 and 20 personnel. NATO and U.S. doctrine define a section as an organization "larger than a squad, but smaller than a platoon." As such, two or more sections usually make up an army platoon or an air force flight.
An artillery observer, artillery spotter, or forward observer (FO) is a soldier responsible for directing artillery and mortar fire support onto a target. An artillery observer usually accompanies a tank or infantry unit. Spotters ensure that indirect fire hits targets which those at a fire support base cannot see.
Long-range surveillance (LRS) teams were elite, specially-trained surveillance units of the United States Army employed for clandestine operation by Military Intelligence for gathering direct human intelligence information deep within enemy territory. Classic LRS employment is to infiltrate deep into enemy territory, construct hide and surveillance sites, and provide continuous surveillance/special reconnaissance of an intelligence target of key interest.
The brigade combat team (BCT) is the basic deployable unit of maneuver in the U.S. Army. A brigade combat team consists of one combat arms branch maneuver brigade, and its assigned support and fire units. A brigade is normally commanded by a colonel (O-6) although in some cases a brigadier general (O-7) may assume command. A brigade combat team contains combat support and combat service support units necessary to sustain its operations. BCTs contain organic artillery training and support, received from the parent division artillery (DIVARTY). There are three types of brigade combat teams: infantry, Stryker, and armored.
Infantry tactics are the combination of military concepts and methods used by infantry to achieve tactical objectives during combat. The role of the infantry on the battlefield is, typically, to close with and engage the enemy, and hold territorial objectives; infantry tactics are the means by which this is achieved. Infantry commonly makes up the largest proportion of an army's fighting strength, and consequently often suffers the heaviest casualties. Throughout history, infantrymen have sought to minimise their losses in both attack and defence through effective tactics.
Reconnaissance, surveillance, and target acquisition (RSTA) squadrons are a type of unit in the United States Army. These are cavalry squadrons, and act at the squadron (battalion) level as a reconnaissance unit for their parent brigade combat teams. These RSTA squadrons continue on the Recondo legacy of the Vietnam era Long Range Reconnaissance Patrols (LRRP), however, compared to the LRRPs they are often assigned additional non-reconnaissance responsibilities such as battlespace ownership.
Cavalry Scout is the job title of someone who has achieved the military occupational specialty of 19D Armored Reconnaissance Specialist in the Combat Arms branch of the United States Army. As with all enlisted soldiers in the United States Cavalry, the person holding the Scout specialization will still be referred to as a "Trooper", the traditional colloquialism denoted in the cavalry's Order of the Spur.
Ghatak Platoons are special operations capable reconnaissance platoons consisting of Shock troopers these are present in every infantry battalion of the Indian Army. Ghatak is a Sanskrit word meaning "killer" or "lethal". Their name was given to them by General Bipin Chandra Joshi. They act as shock troops and spearhead assaults ahead of the battalion.
The Estonian Land Forces, unofficially referred to as the Estonian Army, is the name of the unified ground forces among the Estonian Defense Forces where it has an offensive military formation role. The Estonian Land Forces is currently the largest Estonian military branch, with an average size of approximately 6,000 soldiers, conscripts, and officers during peacetime.
Special reconnaissance (SR) is conducted by small units, such as a recon team, made up of highly trained military personnel, usually from special forces units and/or military intelligence organizations. Special reconnaissance teams operate behind enemy lines, avoiding direct combat and detection by the enemy. As a role, SR is distinct from commando operations, but both are often carried out by the same units. The SR role frequently includes covert direction of airstrikes and indirect fire, in areas deep behind enemy lines, placement of remotely monitored sensors, and preparations for other special forces. Like other special forces, SR units may also carry out direct action and unconventional warfare, including guerrilla operations.
Combat Mission is the name of a series of computer wargames simulating tactical battles. The series has progressed through two distinct game engines. The original game engine, referred to as 'CMx1' by the developer, Battlefront.com, powered a trio of games set in the Second World War. Combat Mission: Shock Force was released in July 2007 as the debut of the 'CMx2' game engine. The Combat Mission games are a mixture of turn-based gameplay and simultaneous real-time execution. The game environment is fully three-dimensional, with a "Wego" style of play wherein each player enters their orders into the computer simultaneously during pauses in the action, and then are powerless to intervene during the action phase. More familiar turn-based games use an "I-go/You-go" system of play.
In military tactics, the kill zone, also known as killing zone, is an area entirely covered by direct and effective fire, an element of ambush within which an approaching enemy force is trapped and destroyed. The objective of the ambush force is to quickly kill or capture all enemy soldiers inside the kill zone. The trapped soldiers may respond by counterattacking.
