What Does Artillery Do in the Military? (Part 1: The Foundations of Firepower)
In the theater of modern land warfare, infantry and armored vehicles capture headlines, but military science acknowledges an immutable truth: artillery remains the decisive heavy engine of combat. Often historically dubbed "the god of war", artillery encompasses a wide array of heavy projectile-launching weapons, ranging from field howitzers and mortars to rocket launchers and tactical missile systems.
Far from simply firing random explosives into the distance, artillery serves as the structural backbone of a modern army's operational capability. Its core mission is deceptively complex: to destroy, neutralize, or suppress the enemy through overwhelming firepower, shape the geometry of the battlefield, and shield friendly ground maneuver units from harm.
Defining the Scope: What Constitutes Artillery?
To understand what artillery does, one must first understand what it is. At its most fundamental level, artillery consists of ranged weapon systems that project munitions far beyond the physical range, caliber, and destructive capacity of standard infantry small arms.
Historically rooted in ancient siege engines like catapults and trebuchets, modern artillery has evolved into a sophisticated technological branch divided into several primary categories:
Tube Artillery (Guns and Howitzers): These barrel-based systems use chemical propellants to fire high-explosive shells over medium to long ranges.
Howitzers are particularly versatile because they can fire at high angles, allowing shells to arc over hills, mountains, and urban obstacles to strike targets hidden on the reverse slopes. Mortars: Typically lighter, smoothbore, or rifled high-angle weapons, mortars are organic to infantry battalions.
They provide immediate, responsive close-support fire directly to frontline troops engaged in close combat. Rocket Artillery: Systems that utilize self-propelled rockets launched in rapid succession from multi-tube platforms (such as truck-mounted or tracked chassis).
They are designed for high-volume area saturation, delivering massive devastation across a wide grid square in a matter of seconds. Missile Systems: Surface-to-surface guided tactical missiles that extend artillery reach deep behind enemy lines, targeting command nodes, logistical hubs, and high-value strategic infrastructure with pinpoint precision.
The Core Doctrine: Shaping the Battlefield
Artillery does not operate in a vacuum; it exists to enable and protect maneuver forces (infantry and tanks). In military doctrine, the employment of artillery is broadly categorized into four primary tactical effects: destruction, neutralization, suppression, and illumination/obscuration.
1. Destruction
Destruction involves putting an enemy target completely out of action, requiring a high volume of accurate rounds to physically demolish hard targets like fortified bunkers, bridges, concrete pillboxes, and communication nodes. Because destruction requires significant ammunition and time, it is usually reserved for pre-planned targets or critical choke points identified well before an offensive push.
2. Neutralization
More frequently utilized than total destruction, neutralization temporarily knocks an enemy unit out of the fight, rendering them incapable of firing, moving, or observing friendly forces. Even if enemy soldiers survive inside hardened trenches, the concussive blasts and shrapnel force them to hunker down, rendering them temporarily combat-ineffective while friendly infantry closes the distance.
3. Suppression
Suppression keeps the enemy's heads down. Unlike neutralization, which aims for casualties and structural damage, suppression relies on the psychological and physical threat of incoming fire to restrict enemy actions. If an enemy machine gunner is forced to seek shelter and cannot acquire targets, they are suppressed—allowing friendly troops to maneuver safely across open danger zones.
4. Screening and Illumination
Beyond sheer destruction, artillery units deploy specialized ordinance to manipulate the sensory environment of the battlefield. Smoke shells create visual barriers to blind enemy direct-fire weapons and conceal advancing friendly troops. Illumination rounds—often containing magnesium flares suspended by tiny parachutes—turn night into day during nocturnal engagements, denying the enemy the cover of darkness.
The Evolution of Indirect Fire
The single greatest leap in the history of artillery was the transition from direct fire to indirect fire at the turn of the 20th century.
In early warfare, artillerists had to see their targets directly down the barrel of their cannons, exposing the guns and their crews to counter-attacks. Modern artillery almost exclusively employs indirect fire.
This separation requires a tightly coordinated chain of communication known as the fire support team:
Forward Observers (FOs) or Spotters: Embedded with frontline infantry or operating via aerial drones, these personnel scout enemy positions and transmit exact target coordinates.
Fire Direction Center (FDC): The analytical brain of the battery. The FDC receives coordinates from the observer, factors in meteorological data (wind speed, air temperature, barometric pressure), barrel wear, and ammunition type, and calculates exact firing solutions.
The Gun Crews: The operators who manually or automatically lay, load, and fire the weapon based on the FDC's digital or verbal instructions.
This sophisticated orchestration allows an army to mass its firepower instantly, concentrating the destructive weight of dozens of scattered guns onto a single target miles away without exposing the weapons to direct enemy observation.
Modern Artillerist in Action: From Target Acquisition to Effect
To understand what artillery accomplishes on the modern battlefield, one must look beyond the physical discharge of a projectile and examine the intricate, high-speed kill chain that transforms a distant coordinate into a neutralized threat. Artillery does not operate in a vacuum; it is the culmination of reconnaissance, data processing, ballistic physics, and lethal synchronization.
The Modern Fire Support Team and Target Acquisition
Long gone are the days when an artillery battery relied solely on forward observers shouting compass bearings and estimated distances through a field radio. Today, the target acquisition network is a multi-layered web spanning orbital, aerial, and terrestrial domains.

Counter-Battery Radars: These sophisticated systems track incoming artillery or mortar rounds in flight, instantly calculating their trajectories backward to pinpoint the exact location of the enemy firing position, allowing for rapid counter-fire before the opposing guns can displace.
Unmanned Aerial Systems (UAVs): Drones provide persistent, real-time video feeds over the battlefield, enabling spotters to identify enemy armor, logistics hubs, and troop concentrations hidden behind terrain folds.
Targeting Terminals: Forward observers and specialized reconnaissance teams carry ruggedized digital tablets integrated with encrypted battlefield management systems. A click on a digital map instantly transmits precise GPS coordinates to the fire direction center.
Ballistics, Meteorology, and the Fire Direction Center (FDC)
Once a target is verified, the request for fire reaches the Fire Direction Center (FDC). Here, artillery officers and computers perform rapid, complex calculations that account for every variable capable of throwing a shell off target.
Artillery is essentially applied physics on a massive scale. The FDC must compute:
Muzzle Velocity Variations: As barrels heat up from continuous firing or wear down over hundreds of rounds, the exit speed of the projectile changes.
Meteorological Data: Wind speed and direction at various altitudes, air temperature, and barometric pressure drastically affect a projectile weighing 100 pounds traveling at supersonic speeds over tens of kilometers.
Rotation and Coriolis Effect: Earth's rotation (the Coriolis effect) and the gyroscopic stability of spinning rifled projectiles must be mathematically anticipated for long-range precision.
Using advanced ballistic computers, the FDC translates these factors into precise elevation and deflection commands, transmitting them digitally directly to the gun crews or automated loading systems.
Precision-Guided Munitions and Smart Artillery
For decades, conventional artillery relied on sheer volume of fire—saturation bombardment—to ensure destruction over a wide area. While area suppression remains vital, the advent of precision-guided munitions (PGMs) has revolutionized what artillery can achieve, turning indirect fire into surgical instruments.
GPS and Inertial Guidance: Projectiles equipped with small tail fins and internal guidance systems can adjust their flight path mid-air to hit coordinates within meters of the intended target, even at extreme ranges exceeding 40 kilometers.
Laser-Guided Shells: A forward observer or drone designates a moving tank or hardened bunker with an invisible laser designator. The incoming artillery shell homes in on the reflected laser energy, turning indirect artillery systems into anti-armor weapons capable of striking moving targets on the first shot.
Sensor-Fused Munitions: Advanced rocket-delivered submunitions descend over an enemy vehicle column, scanning the ground with infrared and millimeter-wave sensors to autonomously detect and attack armor from above, where vehicle armor is traditionally thinnest.
Strategic Depth and Psychological Impact
Beyond tactical engagements, artillery exerts profound strategic influence across an entire theater of operations.
Operational Interdiction
Artillery can seal off entire sectors of a battlefield. By establishing rolling barrages or mine-laying artillery strikes (where shells scatter anti-tank or anti-personnel mines across supply routes), commanders can effectively deny enemy reinforcements the ability to traverse roads, bridges, or mountain passes.
Counter-Mobility and Counter-Fire
In high-intensity peer conflicts, the ability to silence enemy artillery while keeping one's own mobile is paramount. Modern tactics emphasize "shoot-and-scoot" capabilities: self-propelled howitzers fire a multi-round simultaneous impact (MRSI) mission—where several rounds fired at different trajectories land on the target at the exact same millisecond—and immediately pack up and drive away before counter-battery fire can arrive.
The Psychological Dimension
War historians and combat veterans universally note that nothing matches the psychological terror of heavy artillery fire. Unlike direct-fire weapons where a soldier can see the source and take cover behind specific geometry, incoming artillery shells provide no visual warning, screaming through the stratosphere to detonate unpredictably overhead or subterraneanly. It degrades morale, causes profound sensory overload, disrupts command and control through severed communication lines, and forces enemy infantry to remain pinned inside fortifications, neutralizing their operational initiative.
Conclusion: The Indispensable God of War
From the bronze smoothbores of medieval siege trains to the hyper-velocity, AI-assisted, rocket-assisted artillery systems of the twenty-first century, the fundamental mission of artillery has remained remarkably consistent: to deliver overwhelming, decisive violence at a distance, protecting friendly forces while shattering the will and capability of the adversary.
As military technology evolves toward greater automation, extended ranges, and hypersonic velocities, artillery will undoubtedly retain its crown as the true backbone of combined arms warfare—the ultimate arbiter of modern combat supremacy.
