Modern warfare grows more sophisticated by the day—we used to use swords and spears, now we use unmanned planes and robots.
So, just in case you think all the deadliest weapons were created in the last 100 years or so, here are ten from the ancient world that I think you’ll find a little familiar (even if the closest you’ve ever gotten to a battle is playing Call of Duty or Halo).
10. Land Mine

Land mines are explosive devices planted in the ground, and have been used in conflicts all over the world. During the Mongol invasion of China in the 13th century, Chinese inventors came up with the “Underground Sky Soaring Thunder”, a land mine so terrifyingly titled, it’s name alone should’ve been enough to force armies into retreat.
Gunpowder mines were buried in the earth with banners, pikes, and lances stuck on top as bait. When enemies grabbed the weapons, they triggered a slow burning chemical mixture that fell over and ignited the fuses, creating a devastating explosion.
9. Naval Mine

Sure, Queen Elizabeth I had the opportunity to blow up ships when she received plans for a naval mine from Ralph Rabbards in the 16th century, but once again we must look to the trend-setting Chinese for the earliest use.
In the Huolongjing, a Chinese military manual, the “Submarine Dragon King” is described in detail. The gunpowder mine was secured in an inflated ox bladder and the fuse laid inside a length of goat’s intestine to keep it dry. At night, a soldier lit a stick of incense inside the intestine, and sent the mine floating downstream toward an enemy ship. If the timing was right, and the enemy didn’t notice the floating pile of animal guts suspiciously heading in their direction, the incense ignited the fuse and caused an explosion just as the mine reached the ship’s hull.
8. Hand Gun

Following the land and naval mines above, it should be no surprise that the Chinese were amongst the first to take advantage of gunpowder’s explosive capabilities. The tenth century fire lance (or lightweight hand cannon) fired shrapnel at the enemy from a long bronze or iron tube small enough to be carried by a soldier. Though it could be argued this is more of a field artillery piece.
7. Poisonous Gas

Chemical weapons aren’t a new idea, with arsenic and human feces laced incendiary bombs being deployed by the medieval Chinese.
However, in the Peloponnesian War between Athens and Sparta in the fifth century B.C., the Spartans besieging Plataea were the first to employ poison gas by soaking wood in a mixture of sulfur and pitch, lighting the wood on fire, and blowing the choking smoke under the city walls to either kill the defenders or force them to flee.
6. Tank

The Assyrians had armored siege engines in the ninth century B.C., and several ancient generals like Hannibal deployed war elephants on the battlefield, but leave it to the medieval Czech Republic—formerly known as Bohemia—to bring the tank into play.
During his conflicts with the Imperial German Army and Pope Martin V, Jan Zizka, the famous 15th century general who appears on another list—bizarre uses for human skin—ordered his engineers to cover wagons with iron sheets.
Crews in the horse drawn armored vehicles fired weapons through small holes in the sides. These tanks gave Ziska a tactical advantage, allowing his relatively small army of 25,000 to defeat much larger forces of 200,000 attackers.
5. Rocket

Self-propelled rockets have a history spanning several centuries before World War II, originating with the 'Magic Fire Flying Crow.'
In the 14th century, the Chinese developed an incendiary device propelled by four gunpowder-fueled rocket tubes attached to feathered wings. Various warheads could be attached, including poisoned arrow tips, explosives, or, if used at contemporary high schools, notes behind the teacher’s back.
Hand Grenade

Grenades are a destructive weapon of war, but aren’t a modern concept. Some of the earliest hand grenades were produced around the eighth century in Byzantium, and were made of ceramic, terra-cotta, or glass, and filled with highly flammable substances like the famous Greek fire.
To deploy these handheld incendiary bombs, ignite the fuse, hurl them, and then seek cover as your adversaries are engulfed in flames. This tactic was also utilized by Islamic engineers in the Middle East. By the 13th century, Syrian workshops were crafting egg-shaped hand grenades made of pottery.
Flamethrower

In the 8th century, the Byzantine Empire developed a hand-pumped hose that emitted Greek fire—a highly flammable liquid. The Chinese enhanced this in the 10th century with a portable version that projected a continuous stream of naphtha-based flame, known as fierce fiery oil, at the enemy.
These devices were most effectively used in naval combat but could also serve as offensive weapons for infantry soldiers or defensively against advancing forces. However, according to Thucydides, the Greeks pioneered this technique during the Peloponnesian War in 424 B.C., when they inserted a metal tube into a hollow log filled with pitch, sulfur, naphtha, and lit coals, then expelled the flaming mixture at a city's wooden defensive walls in an attempt to destroy them.
2. Torpedo

The self-propelled Whitehead or “automobile” torpedo, created in 1866 by American engineer Roger Whitehead, was an improvement on a model by Johannes Luppis in Austria, which used a compressed air system for propulsion.
An even earlier example of the torpedo comes from a 13th century military manual by an Islamic engineer describing the “egg which moves itself and burns”, which thankfully is not found in modern day kitchens. This was an incendiary torpedo, propelled by gunpowder rockets over the top of the water toward an enemy ship’s hull.
1. Machine Gun

Before the advent of gunpowder and bullets, ancient civilizations relied on crossbows as their closest approximation to firearms. Despite their effectiveness in engaging enemies from a distance, crossbows had a significant limitation—they could only discharge a single bolt per shot.
In the 12th century, the Chinese developed the machine gun crossbow, a remarkable advancement that allowed for aiming in any direction and could fire approximately one bolt per second.
