We don’t have these in the UK we have potholes 😂

Cheap to manufacture, doesn't need high qualification workers, easy to deploy, no risk to engineers in the field, easy to recover, not a danger for post-war life like anti-personnel or anti-tank mines are.

Monty Python posed the question in Life of Brian: "What did the Romans do for us ? " Now we have another thing to add to the list... Brilliant

As an Army engineer, I made it a point to teach armor about concertina. It is far more effective than you might imagine, binding tracks and drive wheels to bring the tanks grinding to a halt and requiring hours of maintenance to undo.

The trick is that the needles are hollow and it allows the air to rush out. The solid needles are less effective

Folks in the Western US still use caltrops to keep hunters and fisherman from trespassing. Or at least getting very far in their 4x4’s and ATV’s. They are cheap and easy to make.

If it ain't broke, don't fix it.

Abandoned by the Romans when the Visigoths developed run-flat tyres on their chariots.

"If it's stupid, But it works, Then it isn't stupid"

We always think that technology is the answer when we might already have all that we need. Thank you for sharing this! Best of luck to the Ukraine!

Everything old is new again, just like clothing...

I thought you meant turning the road signs round the other way to totally confuse the enemy

Without even watching the video, I'm going to guess that the weapon is caltrops. A weapon used by the Romans and Medieval armies to stop cavalry and even infantry charges.

Quebec roads inflict far more damage and not only to the tires.

Didn't James Bond use them from his car?

The old tricks are the best tricks😂

Used caltrops in Northern Ireland during op banner a smaller version carried in flat metal boxes could be pulled across the road quickly if needed

the progression of better mouse - better mousetrap is not linear, and sometimes the old mousetrap works on today's mouse

So, I used to play a vocab game with someone until I brought up caltrops and they quit lol. They were used to maim horses and slow cavalry in the bronze age. Now, same concept except vehicles are the modern cavalry.

Slava Ukraini!

I've seen many of those. When the coal miners were on strike in the seventies in southwest Virginia, the strikers would scatter those on the roads where the coal trucks didn't stop hauling to support the strike. They were very effective.

Just goes to show that sometimes the simplest ideas are the best.

Zoomers discovered anti-tank hedgehogs, but smaller ones

How did I know it was caltrops before even clicking the video?

When are we going to see the trebuchet drone?

Next, they will be talking about bronze-age weapons such as knives.

The Japanese word for Caltrop is Tetsubishi which means iron diamond . Many times in Japanese history a cavalry charge has been blunted by sowing tetsubishi on the battlefield .

Added to pile of game changers.

Caltrops have been in continual use since the Greeks. They were used against cavalry until the modern age. Infantrymen would seed the field in front or throw them into the path of oncoming horsemen, and they have been used in the twentieth and twenty first centuries against soft wheeled vehicles, often dropped by cluster bombs. There are many clever designs. Home made ones were widely used against the Germans by resistance groups in Europe who quietly placed them on roads by hand. The games that little girls used to play called "jacks" with six pointed stars and a rubber ball are miniature versions, and in the seventies oversized ones made of heavy metal were popular as book ends in the United States.

Some ideas never get old.

The hollow tube ones will cut a plug out that no self-sealing tire can possibly counter.

The cartels have been using those in Mexico for decades.

I love that spiral clock at 0:52

It's so useful it make the Russian retreating Forward.

Funny how they all are attached by a chain so they can remove them with a bmp or tracked vehicle, or in some cases by hand given a couple minutes, them shining in the light dont make them very stealthy

Im really amazed the Russians are not using run flat tires by this point

Caesar employ them outside his fortifications during the battle of Alesia , it slowed the charge of the Gauls!!!

The Romans had caltrops with barbs on the spikes, like fishhooks...

They could also be dropped by drones onto power lines and into sub-stations to short out the electrical network in Ruzzia.

Caltrops are super effective. They use big (appx 24") ones to block the closed gates on military bases too.

I used those to keep my wife out of the TV Room when I was watching sports. She wised up & swept them aside with a broom. (as vehicle drivers learned to attach angled brushes to their vehicles to sweep caltrops aside) I finally learned to eat chilli or cabbage before a sporting event. That kept her the Hell away.

Stop Sticks on a chain. Plywood with 16 penny framing nails works wonders too, and very easy to throw leaves and dirt on it, and hide it on a dirt road.

I have 20 of these odd pyramid shaped devices and they certainly will pop a tire lol

Ah my favorite item in D&D!

"Lazy Tom's" where used in Northern Ireland at vehicle check points. By the British Army. They were also taken on patrols for use in random check points. These were a piece of chain with spikes through it. They were quite heavy, and so they would be cut in half. The result was then known as" half lazy Tom's". Ingenious!

Fascinating

This is practical in so many ways crazy how effective an ancient technology is even in present day

Ingenious!

i can hear the war in the air

Ok so all russia needs is high powered magnet on front if tank to pick them up lolol

Old is gold

Smart, keep it up.

In America the police call them a spike strip. It is used to stop vehicles that the police are chasing.

In my country we call them : Miguelitos, older than injustice.

Rommel had larger ones lining the shore on D-Day. They caused a lot of physical problems effecting landing craft and the Allies.

War. War never changes.

What the Romans taught us - lots !

Caltrops? Yup caltrops

This is so genius

Someone took the phrase "Going medieval" exactly the right kind of literally

Creativity is important...

Caltrops

ingeniousity

The old iron cross and razor/barbed wire-destroying tires and machines for the ages

The art of war

So they won’t need the 61 billion $ after all?

Yeah, but all you need to do on a paved road is mount a deflector in front of the tires (that sits like an inch off the ground) and they're no longer a threat. Give it a bit of a spring and put rollers on the edges, and it won't even get damaged when the tire bounces down on the road. I mean, I'm glad that people are being creative, but this is only effective in the very short term.

Genius

Ive heard that the madagaskar navy uses these in their submarines…

Dont forget mud !!

Had those back in the 80's Germany. Only problem was getting them deployed. Was a pain.

Caltrops. Used by armies for centuries. Until gunpowder.

Ivan Ivanovich Ivanovsky: "That's a good idea! Let's do that too!" Meanwhile, Ukrainians are already working on countermeasures.

Ukraine needs all the help that it can get.

The Information Age always lets the enemy know exactly what they are doing.

I thought you were going to say General Winter, but yeah, these work too.

They used them in Korea as well

Simple mais ingénieux.🇺🇦🇨🇵🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵🇺🇦🇨🇵 Bravo 👏👏👏👏👏

Those Romans were smart!

From the title I guessed what it was, because I often think about the Roman Empire.

When you're left with no modern weapons you do this

They always act like this thing can stop the whole Russian advance when in fsct it actually can't.

In domestic life, the equivalent for flattening the feet would LEGOS and/or toy jacks.

Hollow tubes would limit escape by coring the tire instead of a slow leak.

They just made themselves a mark..

they can't stop tank or APC with track

Anyone who’s ever stepped on a Jack will attest to the brutal effectiveness of such a device!

Romans used caltrops against rubber tires? 😲

If they were using hollow pipes to make them, they would cause the tires to go flat more quickly

LMAO This is why the US military has vehicles with airless tires/tires that can drive on the rims.

Everything old is new again! 🤯

"Act accordingly" -wranglerstar

I'm sure this will turn them back, they'd never have come if they had known!

Very smart

Caltrops never stopped being used

Caltrops we not first used by the Romans.

It's not new or reborn,😂 used in all wars , Bosnia I remember them, Iraq etc. Heads up I heard they're using an old caveman technique called ... Fire😂

If it works it works. Solid rubber tyres here we come.

I saw the title and thought, "Nail strips?" Close enough.

Welcome to the world of labor disputes in the Americas. Here they're called "Jack Rocks" and used to disable non-union vehicle traffic trying to cross picket lines or service companies experiencing strikes. Been in wide use here since living memory. Thanks for the drone tip, though. Will file that one away for later, LOL.
