In the high-tech age of artificial intelligence and drones, one would hardly expect rats, bees, or dolphins to play a frontline role in defense and security. Yet across the globe, armies are increasingly enlisting the help of animals for missions ranging from landmine detection to border surveillance. What sounds like science fiction is, in fact, very real. And the results? Nothing short of extraordinary.
Let’s explore how animals are being trained for highly specialized defense operations—and why their unique abilities are giving even the most advanced technologies a run for their money.
The Rat Army: Sniffing Out Landmines, One Step at a Time
One of the most astonishing stories of animal deployment in warfare comes from Cambodia and Africa. Here, African giant pouched rats—nicknamed “HeroRATs”—are being trained to detect buried landmines left over from decades-old conflicts.
These rats are not your average rodents. Weighing up to 1.5 kilograms with long tails and exceptional olfactory senses, these animals are incredibly intelligent and highly trainable. They can detect tiny amounts of TNT with their noses—something even the most expensive machines struggle to do efficiently.
Why Rats?
- Lightweight: They’re too light to trigger the landmines they search for.
- Fast: A trained HeroRAT can scan a tennis court-sized area in 30 minutes. A human with a metal detector would take several days.
- Cost-effective: Training a rat is far cheaper than training a dog or deploying sophisticated sensors.
Organizations like APOPO, a Belgian NGO, have deployed these rats in countries like Angola, Mozambique, and Cambodia. As of today, these rats have helped clear hundreds of thousands of landmines and unexploded bombs, potentially saving thousands of lives.
Border Guards with Wings: India’s Beehive Defense
In a jaw-dropping move, India’s Border Security Force (BSF) has turned to bees to patrol its borders. Specifically, the Indo-Bangladesh border in West Bengal has become a testing ground for an eco-friendly defense system—hanging beehives on fences.
Here’s how it works:
- Beehives are placed on or near fences.
- Flowering plants are grown nearby to sustain the bees.
- Anyone trying to tamper with the fence is immediately attacked by the disturbed bees.
This unconventional method has proven surprisingly effective. Smugglers and illegal migrants are now wary of the deadly sting of an angry swarm. The BSF personnel have even undergone training in apiculture to maintain the hives properly.
U.S. Navy’s Secret Weapon: Dolphins and Sea Lions
The U.S. Navy has been training dolphins and sea lions for decades under its Marine Mammal Program. Their mission? To detect underwater mines and protect naval bases.
Why Use Marine Mammals?
- Echolocation: Dolphins use sonar that outperforms human-made sonar devices to locate underwater mines or enemy divers.
- Trainability: Both dolphins and sea lions can be trained to tag enemy swimmers or retrieve objects from the ocean floor.
- Stealth and Accuracy: These animals can perform tasks quickly and quietly in hostile underwater environments.
Not to be outdone, Russia has also experimented with using dolphins for reconnaissance and even claimed to have used them for espionage purposes.
Ukraine’s War Rats: Helping Clear Dangerous Minefields
The war in Ukraine has left vast areas littered with landmines. Enter the rats. Ukraine has teamed up with organizations to deploy HeroRATs to scan large fields and urban zones for unexploded ordnance.
Given their speed, accuracy, and adaptability, these rats are becoming a crucial part of humanitarian demining operations. They are also being deployed in areas where it’s too dangerous for humans to work, especially in active conflict zones.
Airport Rats? Israel Thinks It’s a Brilliant Idea
Israel, known for cutting-edge defense technology, has introduced trained rats in its airport security systems. These rats are used to sniff out explosives in baggage—something that might raise eyebrows but has proven surprisingly efficient.
Due to their small size and superior sense of smell, rats can search through luggage faster and with greater accuracy than machines. Israeli intelligence believes that using animals this way adds a layer of unpredictability that makes it harder for terrorists to smuggle in contraband.
Rats vs. Machines: Why Rodents Are Beating Technology
Rats, unlike metal detectors, can also identify plastic-based landmines that may not trigger a metal-based sensor. They’re also more agile in tight or cluttered environments, and their ability to adapt to changing conditions gives them an edge over rigid algorithms or sensors.
Additionally, they bond with trainers and respond well to positive reinforcement—making them loyal, reliable, and easy to handle in the field.
Beyond War: Animals in Disaster Relief and Health
These animal heroes aren’t just limited to war zones. Rats have also been trained to detect tuberculosis by sniffing samples in labs. Some rats can identify TB infections faster than conventional lab tests—potentially saving lives in poorer countries.
Meanwhile, bees have been experimented with for detecting diseases, and rats have been trained to locate people trapped in earthquake rubble by scent.
