Infantry - Operations

Operations

Attack operations are the most basic role of the infantry, and along with defense, form the main stances of the infantry on the battlefield. Traditionally, in an open battle, or meeting engagement, two armies would maneuver to contact, at which point they would form up their infantry and other units opposite each other. Then one or both would advance and attempt to defeat the enemy force. The goal of an attack remains the same: to advance into an enemy-held objective and dislodge the enemy, thereby establishing control of the objective.

Attacks are often feared by the infantry conducting them because of the high number of casualties suffered while advancing to close with and destroy the enemy while under enemy fire. In mechanized infantry the armored personnel carrier (APC) is considered the assaulting position. These APCs can deliver infantrymen through the front lines to the battle and contribute heavy firepower to engage the enemy. Successful attacks rely on sufficient force, preparative reconnaissance and battlefield preparation with bomb assets. Retention of discipline and cohesion throughout the attack is paramount to success. A subcategory of attacks is the ambush, where infantrymen lie in wait for enemy forces before attacking at a vulnerable moment. This gives the ambushing infantrymen the combat advantage of surprise and causes confusion. The ambushed unit does not know what is up against or where they are attacking from.

Defense operations are the natural counter to attacks, in which the mission is to hold an objective and defeat enemy forces attempting to dislodge the defender. Defensive posture offers many advantages to the infantry, including the ability to use terrain and constructed fortifications to advantage and the reduced exposure to enemy fire compared with advancing forces. Effective defense relies on minimizing losses to enemy fire, breaking the enemy's cohesion before their advance is completed, and preventing enemy penetration of defensive positions.

Patrol is the most common infantry mission. Full scale attacks and defensive efforts are occasional, but patrols are constant. Patrols consist of small groups of infantry moving about in areas of possible enemy activity to locate the enemy and destroy them when found. Patrols are used not only on the front-lines, but in rear areas where enemy infiltration or insurgencies are possible.

Pursuit is a role that the infantry often assumes. The objective of pursuit operations is the destruction of enemy forces which are not capable of effectively engaging friendly units before they can build their strength to the point where they are effective. Infantry traditionally have been the main force to overrun these units in the past, and in modern combat are used to pursue enemy forces in constricted terrain (urban areas in particular), where faster forces, such as armored vehicles are incapable of going or would be exposed to ambush.

Escort consists of protecting support units from ambush, particularly from hostile infantry forces. Combat support units (a majority of the military) are not as well trained and have a very different mission than infantry units, they need the protection of the infantry. This is one of the most important roles for the modern infantry, in particular when operating along side armored vehicles. In this capacity, infantry essentially conducts patrol on the move, scouring terrain which may hide enemy infantry waiting to ambush friendly vehicles, and identifying enemy strong points for attack by the heavier units.

Maneuver operations consume much of an infantry unit's time. Infantry, like all combat arms units, are often maneuvered to meet battlefield needs, and often must do so under enemy attack. The infantry must maintain their cohesion and readiness during the move to ensure their usefulness when they reach their objective. Traditionally, infantry have relied on their own legs for mobility, but mechanised or armoured infantry often uses trucks and armored vehicles for transport, but can easily transition to light infantry, without vehicles, to access terrain which armored vehicles can't access.

Reconnaissance/intelligence gathering Surveillance operations are often carried out with the employment of small recon units or sniper teams which gather information about the enemy, reporting on characteristics such as size, activity, location, unit and equipment. These infantry units typically are known for their stealth and ability to operate for periods of time within close proximity of the enemy without being detected. They may engage high profile targets or be employed to hunt down terrorist cells and insurgents within a given area. These units may also entice the enemy to engage a located recon unit thus disclosing their location to be destroyed by larger combat assault forces.

Reserve assignments for infantry units involve deployment behind the front, although patrol and security operations are usually maintained in case of enemy infiltration. This is usually the best time for infantry units to integrate replacements into units and to maintain equipment. Additionally, soldiers can be rested and general readiness should improve. However, the unit must be ready for deployment at any point.

Construction can be undertaken either in reserve or on the front, but consists of using infantry troops as labor for construction of field positions, roads, bridges, airfields, and all other manner of structures. The infantry is often given this assignment because of the physical quantity of strong men within the unit, although it can lessen a unit's morale and limit the unit's ability to maintain readiness and perform other missions. More often, such jobs are given to specialist engineering corps.

Base defense is where infantry units are tasked to protect certain areas like command posts or airbases. Units assigned to this job usually have a large amount of military police attached to them for control of checkpoints and prisons.

Raid/Hostage Rescue Infantry units are trained to quickly mobilize, infiltrate, enter and neutralize threat forces when appropriate combat intelligence indicates to secure a location, rescue or capture high profile targets.

Urban Combat Urban combat poses unique challenges to the combat forces. It is one of the most complicated type of operations an infantry unit will undertake. With many places for the enemy to hide and ambush from, infantry units must be trained in how to enter a city, and systematically clear the buildings, which most likely will be booby trapped, in order to kill or capture enemy personnel within the city. Care must be taken to differentiate innocent civilians who often hide and support the enemy from the nonuniformed armed enemy forces. Civilian and military casualties both are usually very high. US Infantrymen fared very well in the urban combat, of Iraq, especially in the hand to hand close combat Fallujah, Iraq (2004). This clearly demonstrates the effectiveness and lethal nature of modern infantry training and techniques despite the mass use of civilians as shields and the posing of the enemy as civilians.

Famous quotes containing the word operations:

    A sociosphere of contact, control, persuasion and dissuasion, of exhibitions of inhibitions in massive or homeopathic doses...: this is obscenity. All structures turned inside out and exhibited, all operations rendered visible. In America this goes all the way from the bewildering network of aerial telephone and electric wires ... to the concrete multiplication of all the bodily functions in the home, the litany of ingredients on the tiniest can of food, the exhibition of income or IQ.
    Jean Baudrillard (b. 1929)

    There is a patent office at the seat of government of the universe, whose managers are as much interested in the dispersion of seeds as anybody at Washington can be, and their operations are infinitely more extensive and regular.
    Henry David Thoreau (1817–1862)

    You can’t have operations without screams. Pain and the knife—they’re inseparable.
