Infantry is a military specialization which engages in ground combat on foot. Infantry generally consists of light infantry, mountain infantry, motorized infantry, marine infantry, mechanized infantry and airborne infantry.
A battalion is a military unit, typically consisting of 300 to 1,000 soldiers commanded by a lieutenant colonel, and subdivided into a number of companies. In some countries, battalions are exclusively infantry, while in others battalions are unit-level organizations.
A company is a military unit, typically consisting of 80–250 soldiers and usually commanded by a major or a captain. Most companies are formed 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 or more squads, sections, or patrols. Platoon organization varies depending on the country and the branch, but a platoon can be composed of 50 people, 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 amongst 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.
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, 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. 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.
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 six and 20 personnel. NATO and US 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.
Land Warrior was a United States Army program, cancelled in 2007 but restarted in 2008, that used a combination of commercial, off-the-shelf technology (COTS) and current-issue military gear and equipment designed to:
The People's Liberation Army Ground Force is the land-based service branch of the People's Liberation Army and the largest and oldest branch of the entire Chinese armed forces. The PLAGF can trace its lineage from 1927 as the Chinese Red Army; however, it was not officially established until 1948.
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) refers to a joint doctrine of reconnaissance, surveillance and target acquisition conducted by the United States Armed Forces. RSTA operations are designed to support military operations at a strategic, operational, or tactical level, either by dedicated RSTA forces or those which possess the capability.
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.
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. It is currently the largest Estonian military branch with the average size during peacetime of approximately 6,000 soldiers, conscripts, and officers.
Special reconnaissance (SR) is conducted by small units of highly trained military personnel, usually from special forces units or military intelligence organizations, who 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 fires, 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.
Individual movement techniques or IMTs are the most basic tactics that are employed at the fireteam, squad, section or platoon level. They are similar in most modern armies.
Combat Mission is the name of a successful 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.
