Does Artillery Include Guns? The Anatomy of Heavy Ordnance (Part 1)

When people picture modern land warfare or historical battles, the thunderous roar of heavy machinery immediately comes to mind. Terms like "artillery," "cannons," "howitzers," and "guns" are frequently tossed around interchangeably in casual conversation, movies, and literature. However, from a technical, historical, and military science perspective, the relationship between these terms is deeply nuanced. To answer the fundamental question—does artillery include guns?—we must look deep into military doctrine, physics, and the evolution of weaponry.

The short, definitive answer is yes; guns are a primary component of artillery. But in professional military nomenclature, not all artillery pieces are "guns," and understanding why reveals a fascinating taxonomy of heavy combat power.

Defining the Terms: What is Artillery?

To understand how guns fit into the broader category of artillery, one must first define what artillery actually is. Historically and modernly, artillery refers to crew-served large-caliber weapons and systems that exceed the size, weight, and destructive capacity of individual infantry small arms (such as rifles, carbines, and light machine guns).

While the word originally derived from medieval French terms relating to any manufactured weaponry or defensive gear (including bows, slings, and siege engines), the advent of gunpowder permanently shifted the definition. Today, artillery encompasses a vast spectrum of heavy ordnance designed to deliver explosive, incendiary, or kinetic payloads across ranges far beyond the reach of standard infantry units.

Artillery is broadly split into two main organizational concepts:

• The Hardware/Equipment: The physical weapons systems, including traditional barrel artillery (guns, howitzers, and mortars) and modern rocket-launching systems.

• The Combat Arm: The specific branch of a nation’s military forces responsible for operating these heavy weapon systems and providing fire support.

Because artillery requires specialized teams to transport, load, aim, and maintain, it is fundamentally crew-served. This requirement separates an artillery piece from a soldier's personal firearm. Within this broad umbrella of crew-served heavy ordnance, the "gun" holds a very specific and prestigious lineage.

Where Guns Fit Into the Artillery Family

In civilian parlance, any device that shoots a projectile using expanding gas from burning propellant is loosely called a "gun." However, within military science and artillery taxonomy, a gun is a very precise sub-classification.

A traditional artillery gun possesses distinct mechanical and ballistic properties that set it apart from its siblings in the artillery family, such as howitzers and mortars. The defining characteristics of a true artillery gun include:

• High Muzzle Velocity: Guns are engineered to propel their projectiles at exceptionally high speeds.

• Long, Heavy Barrels: To achieve that velocity, a gun typically features a long barrel relative to its caliber size, allowing expanding propellant gases to press against the projectile for a longer duration.

• Flat Trajectory: Guns are designed primarily for direct fire or relatively low-angle indirect fire, meaning the projectile travels in a flatter, more direct line toward the target.

Historically, classic long-range field guns and anti-tank weapons were built to engage enemy targets directly, where the gunner could physically see the target through sights. Even when used in indirect fire roles, a gun maintains a flatter trajectory profile than a howitzer. Therefore, all artillery guns are artillery, but not all artillery pieces are guns.

The Spectrum of Barrel Artillery: Guns vs. Howitzers vs. Mortars

To fully grasp how guns fit into artillery, one must compare them to the other primary types of barrel artillery (often collectively called cannon artillery). The military draws strict lines based on how these weapons throw their payloads:

The Ballistic Rule: The distinction between artillery types traditionally relies on barrel length, elevation capability, and trajectory curvature rather than mere size.

1. The Gun: Features a long barrel and high muzzle velocity, firing on a relatively flat trajectory to punch through armor or strike targets directly.

2. The Howitzer: Occupies the middle ground of artillery. It features a shorter barrel than a pure gun and is specifically designed to fire projectiles at higher elevation angles. This creates a curved, plunging trajectory, allowing the explosive shell to clear intervening terrain (like mountains or ridges) and drop down onto enemy positions from above.

3. The Mortar: Typically characterized by a smoothbore, short tube and a baseplate where a shell is dropped down the muzzle to slide and fire. Mortars specialize in high-angle, plunging fire at relatively short ranges, serving as close-support assets directly alongside infantry units.

Despite these technical distinctions, military organizations often use terms fluidly. For instance, the United States Army historically and doctrinally uses "artillery piece" as a catch-all, while many other forces broadly refer to everything as a "gun" in casual service dialogue, even if the asset is technically a howitzer.

Historical Evolution: The Integration of Guns into Artillery

The integration of guns into artillery is a centuries-long story of metallurgical advancement, tactical revolution, and the quest for greater range and accuracy. In the early days of gunpowder, siege cannons were massive, immobile tubes crafted from bronze or iron. These early ancestors of modern artillery were brought to the battlefield specifically to bash down stone castle walls and medieval fortifications.

As manufacturing techniques improved during the Renaissance and the Industrial Revolution, armies realized that heavier ordnance could be split into specialized categories. Cannons evolved into distinct fields:

• Siege and garrison guns for destroying fortifications.

• Field guns mounted on wheeled carriages that could move alongside marching infantry to sweep enemy formations with solid shot or early explosive shells.

• Naval guns adapted for ship-to-ship combat.

The late 19th and early 20th centuries marked the true golden age of the artillery gun, punctuated by revolutionary engineering milestones like the French Canon de 75 modèle 1897, which introduced a hydro-pneumatic recoil mechanism. This mechanism allowed the gun barrel to slide backward upon firing and automatically return to its exact position without moving the carriage. This breakthrough transformed artillery guns from slow, single-shot siege engines into rapid-firing tactical assets capable of sustained bombardment.

The Modern Synthesis: Gun-Howitzers and Rocket Systems

To fully answer whether artillery includes guns, one must examine the evolution of modern military classification. Throughout the latter half of the 20th century and into the 21st century, traditional distinctions between flat-trajectory guns and high-trajectory howitzers began to blur significantly.

Military engineers realized that battlefield versatility required combining the high muzzle velocity and long-range flat fire of a traditional gun with the variable elevation and lobbing capabilities of a howitzer. Consequently, modern artillery design gave birth to the gun-howitzer.

• Dual-Capability Design: These systems can fire at low angles for direct engagement or high angles for indirect fire over terrain obstacles.

• Nomenclature Nuances: While international armies often classify these versatile pieces broadly as howitzers or simply artillery pieces, specific military doctrines (such as the British Army) historically retained the designation "gun" for almost all direct or indirect barrel-based field artillery.

• Beyond Barrels: Modern artillery has also expanded past traditional barrel-fired projectiles to include rocket artillery and tactical missile systems, proving that the category continuously stretches to accommodate new technologies while keeping core gun systems at its heart.

Why the Distinction Still Matters in Doctrine

Despite technological convergence, artillery officers, logicians, and historians maintain strict definitions for a reason. Tactical employment depends heavily on the specific physics of the weapon system:

"A gun trades elevation for velocity, a howitzer trades velocity for versatility, and a mortar trades range for portability and high-angle plunging fire."

1. Ballistic Profiles: True guns operate with long barrels and high propellant charges, creating extreme muzzle velocities ideal for anti-tank warfare or counter-battery fire.

2. Logistics and Training: Crews training on gun-type artillery must calculate hyper-accurate flat-trajectory data, whereas mortar and rocket crews focus heavily on meteorological variations affecting high-arc, long-dwell projectiles.

3. Organizational Structure: Within military branches, batteries are structured explicitly around their primary hardware—distinguishing between towed gun units, self-propelled tracked systems, and multiple launch rocket systems (MLRS).

Conclusion: The Verdict on Artillery and Guns

Ultimately, does artillery include guns? Yes, absolutely. In fact, guns represent the historical backbone and technical core of what artillery has evolved to become.

While the broader umbrella of artillery also embraces howitzers, mortars, and rocket launchers, the word "gun" serves as both a specific subset of barrel artillery and a general colloquialism for any heavy ordnance piece. Understanding this relationship prevents confusion between infantry small arms and heavy combat assets, anchoring our comprehension of military history and modern defense technology alike.
