In the ever-evolving landscape of modern warfare, a seemingly new player has emerged, that has been punching well above its weight class: the small, unmanned aerial vehicle (UAV), or “drone”. These compact, agile, and increasingly affordable devices are revolutionizing battlefield tactics, offering capabilities that were once the domain of larger, more expensive military assets.
The Rise of the Miniature Air Force
Gone are the days when drones were solely the purview of well-funded militaries. While unmanned, remotely-piloted military drones are certainly nothing new, having been used in combat as far back as World War 2, and while used on a large scale as recently as the six-week long Nagorno-Karabakh War in 2020, it is important to realize that many of the recent uses of drones were not “revolutionary” in any way. In fact, Azerbaijan’s use of drones was essentially a copy of the US and Coalition air force’s campaign against Saddam Hussein’s capital in Baghdad, in 1991.

Today, however, it is the comparatively cheap, off-the-shelf commercial drones, often modified specifically for military use, which have become almost ubiquitous on battlefields around the world. From the conflict in Ukraine to the wars in the Middle East, small drones began making their presence felt as early as 2015.
These miniature flying machines come in various shapes and sizes, from hand-launched fixed-wing craft to multi-rotor copters that can take off and land vertically. What they lack in size, they make up for in versatility and sheer numbers. This is driven by their low cost (as low as $40, as of late 2024), and ease of use, as their control interfaces are based on either popular video game controllers, or on smartphone app interfaces, again often mimicking video game apps.

Revolutionizing Reconnaissance
While “kamikaze” and bomb-dropping drones are certainly newsworthy, perhaps the most significant impact of small drones repurposed for military use has been in the realm of reconnaissance. Traditionally, gathering intelligence on enemy positions often required putting soldiers in harm’s way or relying on expensive satellite imagery. Now, a soldier as far down as the squad level (8-13 troops) can launch a drone from a safe position and get real-time video feedback of enemy locations, fortifications, and movements.
This capability has significantly democratized battlefield intelligence. Now, even small units can now have their own “eye in the sky,” providing unprecedented situational awareness. The psychological impact is also significant – the constant buzz of drones overhead can be deeply unnerving for opposing forces, never knowing when they’re being watched…or targeted.

From Eyes to Claws: The Weaponization of Small Drones
While reconnaissance remains a primary function, small drones are increasingly being weaponized. In some conflicts, commercial drones have been modified to drop small explosive payloads, usually modified hand grenades or rocket-propelled grenade (RPG) rounds, and do so with surprising accuracy. This last has, in fact, been used frequently on Ukrainian battlefields to counter the threat posed by main battle tanks. This has allowed for precise (if small scale) strikes on localized high-value targets without risking pilot’s lives or using expensive guided missiles.
A significant factor in this, is the timeliness of engagement, as a local unit with armed drones can act to engage a target far faster than it could using the old methods of calling back to an artillery or missile base, in order to adjust and coordinate fires; while that can – and is – still done with more conventional artillery, the weaponized drone – under the command of a leader literally shoulder to shoulder with the operator – can engage a group of targets much faster than before.
The low cost and expendable nature of these drones also enable swarming tactics. A swarm of small, explosive-laden drones, whether operating as kamikaze’s or under positive control, can overwhelm older, conventional defenses designed to counter larger, conventional threats. This asymmetric capability allows smaller forces to challenge larger, better-equipped opponents.
Leveling the Playing Field
Perhaps the most profound impact of small drones is how they’re leveling the playing field in asymmetric conflicts. Non-state actors and smaller military forces can now possess capabilities that were once the exclusive domain of major powers. A few thousand dollars worth of drones can now threaten millions of dollars worth of military hardware, and can frighten and demoralize professional troops who lack the knowledge, skills, training or equipment to effectively deal with this type of threat.
This democratization of air power is forcing a rethink of traditional military doctrine. Heavy armor, once the king of the battlefield, is increasingly vulnerable to drone-spotted artillery or direct drone attacks; current ad hoc armor strategies to counter drone strikes have only “sort of” worked. Air superiority, traditionally achieved through fighter jets and large drones, now also requires countering swarms of much smaller, harder-to-detect UAV’s. If anything, this threat is much harder for conventional armies to deal with.
The Counter-Drone Challenge
As small drones reshape offensive tactics, they’re also spawning a new field of counter-drone technology. Militaries around the world are racing to develop effective countermeasures, from electronic warfare systems that can jam drone controls to directed energy weapons that can shoot them out of the sky. Some novel approaches include training eagles to intercept drones, using large nets to capture them, or deploying “hunter-killer” drones to pursue and neutralize hostile UAV’s. Obviously, these advanced systems – while they may work for the moment – are breathtakingly expensive for the threats they are envisioned to be deployed against.
The challenge is significant – how do you economically counter a threat that might cost only a few hundred dollars per unit?

While conventional systems such as the combat-proven C-RAM and the venerable ZSU-23-2 can be fitted with proximity-fuzed warheads and self-destruct systems to help prevent “friendly fire” incidents, the dollar gap – something that always looms large in the conduct of war – is still far too wide for these systems to be truly cost-effective in combat. Likewise, conventional rifles are nearly useless against drones, as their projectiles – while perfectly suitable against a human-sized target – are nearly impossible to use against a fast-moving target roughly the size of a human hand.

Is there a better option?
Shotguns vs. Drones: A Low-Tech Solution to a High-Tech Threat
While militaries and defense contractors pour millions into developing advanced counter-drone technologies, one surprisingly effective tool has emerged from a much older era of warfare: the conventional shotgun.
The oldest model of personal firearm in history, shotguns have been continuously used in combat since the invention of gunpowder. As early as the 1980’s, if not before, conventional 12-gauge pump-action shotguns were mounted under the barrels of rifles such as the M-16, usually as supplementary weapons for police SWAT units to use in blasting open locked doors during raids; in fact, a Mossberg 500 was mounted under an M-16 look-alike in the 1987 movie “Predator“. Although terribly front-heavy, this sort of “combination weapon” does have its uses, when in trained hands.

Militaries around the world have used shotguns for both combat and recreation. The shooting sports of “trap” and “skeet” are particularly relevant here, as both are based on hitting very small, fast moving targets with little lead-time.

Shotguns offer several advantages in countering small drones:
- Widespread Availability: Most military and law enforcement units already have shotguns, making them an immediately accessible solution.
- Ease of Use: Soldiers are often already trained in shotgun use, and even if they are not, only minimal additional training is required.
- Wide Dispersal Pattern: The ever-widening spread of shotgun pellets after they leave the muzzle increases the likelihood of hitting a small, fast-moving target.
- Cost-Effective: Compared to expensive electronic warfare systems or laser weapons, shotgun shells are incredibly cheap.
- Low Collateral Damage: Unlike missiles or explosives, shotgun pellets have a limited range, reducing risks to surrounding areas.
Real-World Applications
Several militaries have already employed shotguns against drones. U.S. forces in Syria and Iraq have used them to down small ISIS drones, while developments continue to seek out solutions to develop anti-drone ammunition for conventional weapons. Meanwhile, in Ukraine, Russian companies are developing specialized anti-drone shotguns for the battlefield. And all the while, the inability of most military forces to convince their civilian-staffed governments – most of whom have no military experience at all – that going back to older designs continues to leave expensively trained and equipped troops vulnerable on the battlefield.
Despite their advantages, shotguns are not a perfect solution:
- Limited Range: Effective range is typically less than 100 meters, requiring the threat to be relatively close.
- Manual Targeting: Unlike automated systems, shotguns require a human operator to spot and shoot the drone.
- Multiple Shots: Often, multiple shots are needed to down a drone, especially if it’s a larger or more robust model.
- Environmental Factors: Wind, obstacles, and poor visibility can significantly affect accuracy.
- Escalation Risks: In some scenarios, using firearms against drones could be seen as an escalation, particularly in sensitive diplomatic situations.
Still, shotguns do at least offer a fast solution to the close-range defense problem, when the alternatives are foot-long autocannon rounds or worse, anti-aircraft missiles to deal with what is essentially a lethal child’s toy.
Conclusion: Small Size, Big Shift
While the proliferation of small drones on the battlefield represents a significant shift in military tactics and strategy, they are like most developments: there is a lot of flash and thunder early on, but military forces that are actually competent will quickly adapt, and find countermeasures. All the same, these diminutive devices are rewriting the rules of military engagement, challenging long-held assumptions about military power, and forcing a reevaluation of everything from equipment procurement to tactical doctrine.
As technology continues to advance, making drones smaller, smarter, and more capable, their impact on warfare is only likely to grow. The military forces that can best adapt to this new reality – leveraging the strengths of small drones while effectively countering their threats – will hold a significant advantage on the battlefields of the future.
In the grand chess game of global conflict, the smallest pieces on the board are proving that size isn’t everything. The age of the small drone has arrived, and with it, a new era of warfare where the tiny can have a truly outsized impact.
